Insulation in Alpharetta, GA
Crawl space encapsulation in Alpharetta solves one problem more than any other: humidity wicking into floor systems from Georgia red clay. The 1990s and 2000s homes throughout Windward, Kimball Bridge, and Crabapple sit on vented crawl spaces that pull damp air upward year-round, which makes the first floor feel musty and drives cooling bills up. Spray foam and attic air sealing address the same root issue from above because Alpharetta attics hit 140°F in late summer while the humidity outside hovers near 70 percent. That combination punishes ductwork. Call (855) 657-3403 and a live person picks up, 24/7, ready to schedule a walk-through.
Why Alpharetta Homes Are Different
Alpharetta’s toughest insulation jobs follow a pattern we see every week. Homes built between 1990 and 2010 were framed fast, and the original insulation was usually code-minimum blown fiberglass. Twenty-five years later, that fiberglass has compressed in the cathedral ceiling sections and settled away from the top plates. Add in the multi-plane rooflines that dominate Windward and the golf club communities, and a standard “blow more on top” approach skips the actual problem. The bonus room over the garage is the clearest example: the garage ceiling below often has R-13 or nothing, the knee walls on each side are uninsulated, and the floor insulation between the joists has slipped. Residents of Alpharetta routinely tell us that room is 10 degrees hotter than the rest of the house in July. The fix is rarely more attic insulation. It’s air sealing the floor system and insulating the knee walls. Alpharetta sits in IECC Climate Zone 3A, mixed-humid, so we also watch for moisture accumulation at roof decks when a home gets over-sealed. Any reputable crew should test that, not guess.
Most homes here sit in deed-restricted subdivisions. That means HOA approval can slow down any exterior work, though interior insulation and crawl space jobs rarely trigger review. For attic and crawl space work, no Alpharetta permit is typically required beyond what the HOA asks. Dispatch for Alpharetta jobs runs through our Atlanta office, so scheduling is local and same-week in most cases.
Our Main Alpharetta Services
Two services account for most of the calls we get from Alpharetta homeowners. Attic insulation tops the list, and crawl space encapsulation runs a close second once people smell the damp. Here’s what each one looks like in this city.
Attic Insulation in Alpharetta
Alpharetta attics are bigger, hotter, and more broken-up than what you’d find in older Atlanta neighborhoods. Ductwork crosses unconditioned space for 30 feet or more, and the original R-30 fiberglass has settled to R-19 or worse in cathedral sections. We pull the old material where it’s failed, air seal the top plates, and blow in fresh coverage to a true R-38 or R-49 depending on the home. Most jobs finish in one visit.

Crawl Space Encapsulation & Vapor Barrier in Alpharetta
Crawl space encapsulation in Alpharetta usually starts because a homeowner notices a damp, earthy smell in the first-floor hallway or warped hardwood near the kitchen. The fix is more than laying plastic on the ground. In Alpharetta’s mixed-humid climate, a vented crawl space pulls saturated outside air under the house every time the AC runs, and that moisture feeds mold and rot inside floor joists. Encapsulating the space means sealing the vents, lining the floor and foundation walls with a heavy vapor barrier, and managing the air so the crawl space becomes a dry, conditioned part of the home. Our Crawl Space Encapsulation & Vapor Barrier process handles vented and unvented spaces, with everything backed by the 90-Day Done Right Promise.
Crawl Space Vapor Barrier
Signs you need it
You smell mildew when the AC kicks on, or you see condensation on ductwork and copper pipes under the house. Standing water after heavy rain is another red flag.
What it costs in Alpharetta
Installing a reinforced 12-mil vapor barrier over the crawl space floor in Alpharetta typically runs $1,200 to $2,800 depending on square footage and access height.
How we do it
We clear debris, level high spots, and lay a 12-mil reinforced barrier across the floor, running it up the foundation walls and sealing every seam. The barrier is mechanically fastened, not just weighted down.
Crawl Space Encapsulation
Signs you need it
Your floors feel cold in winter and damp in summer, or the relative humidity in the crawl space reads above 65 percent on a warm day. High humidity below the house also drives up the load on the AC.
What it costs in Alpharetta
Full encapsulation in Alpharetta, including sealing vents and lining walls, typically runs $4,500 to $9,000 for a standard 1,500 to 2,000 square foot crawl space.
How we do it
We seal foundation vents, insulate the rim joists, and install a continuous vapor barrier over floor and walls. Then we add a dehumidifier sized to the space so humidity holds below 55 percent.
Crawl Space Insulation
Signs you need it
The floor above the crawl space is noticeably colder than the rest of the house in January, or your current fiberglass batts are sagging, wet, or falling out of the joist bays.
What it costs in Alpharetta
Insulating crawl space walls or rim joists in Alpharetta usually runs $1,500 to $3,500 depending on whether the space is encapsulated first.
How we do it
We remove failed batts and install closed-cell spray foam or rigid foam board on the foundation walls and rim joists. That stops air movement at the floor line and keeps the joists dry.
What Crawl Space Encapsulation & Vapor Barrier Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| 12-mil vapor barrier (floor only) | $1,200 - $2,800 |
| Full encapsulation with dehumidifier | $4,500 - $9,000 |
| Crawl space wall or rim joist insulation | $1,500 - $3,500 |
Does encapsulation help with Alpharetta’s humidity problem?
Yes. Alpharetta’s dew point stays high from May through September, so a vented crawl space is almost always condensing moisture somewhere. Sealing the space and running a dehumidifier keeps that moisture from moving into floor joists and first-floor living areas. Call (855) 657-3403 to have us measure your crawl space humidity before you decide.
Can you encapsulate a crawl space with a low ceiling?
We can. Some Alpharetta crawl spaces have clearance under 30 inches, which makes the work slower and more physically demanding. The price reflects the extra labor, but the result is the same dry, conditioned space. Estimates are free and upfront.
Spray Foam Insulation in Alpharetta
Spray foam is the right tool for Alpharetta attics where ductwork runs through unconditioned space and temperatures peak above 140°F in August. Open-cell foam on the roofline pulls ducts into a semi-conditioned space and cuts the 20 to 30 percent cooling loss that a hot attic forces on the HVAC system. Closed-cell foam does the same thing with added moisture resistance, which matters for roof decks in a mixed-humid climate. For Windward homes with complicated rooflines and buried duct runs, spray foam is often the most effective single upgrade. See our Spray Foam Insulation process for full details on open-cell and closed-cell options.
Open-Cell Spray Foam
Signs you need it
Your upstairs runs 5 to 8 degrees warmer than downstairs in summer, and the ducts in the attic are sweating. If the attic is vented and the ducts are buried in fiberglass, open-cell foam on the roofline solves both problems.
What it costs in Alpharetta
Open-cell foam applied to an attic roofline in Alpharetta typically runs $1.75 to $3.00 per board foot, or roughly $4,000 to $8,000 for a 2,000 square foot attic.
How we do it
We prep the roofline, mask off soffits to preserve ventilation, and spray a continuous layer of open-cell foam across the underside of the roof deck. Then we air seal the attic floor penetrations.
Closed-Cell Spray Foam
Signs you need it
You have moisture staining on the underside of the roof deck, or you want the highest R-value per inch in a tight space. Closed-cell also adds structural rigidity to older roof decking.
What it costs in Alpharetta
Closed-cell foam in Alpharetta runs $2.50 to $4.50 per board foot, so a full 2,000 square foot roofline lands in the $10,000 to $16,000 range.
How we do it
We apply closed-cell foam directly to the roof deck and gable walls in a continuous layer. Once cured, it forms an air, vapor, and thermal barrier in one pass. We use products from Icynene and Demilec.
What Spray Foam Insulation Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Open-cell roofline (2,000 sq ft attic) | $4,000 - $8,000 |
| Closed-cell roofline (2,000 sq ft attic) | $10,000 - $16,000 |
| Rim joist spray foam (per bay) | $120 - $250 |
Is spray foam worth it in Alpharetta’s climate?
For homes with ductwork in the attic, yes. Alpharetta’s summer attic temperatures rob 20 to 30 percent of cooling output before air reaches the rooms. Encapsulating the roofline with foam recovers most of that loss. The payback shows up in summer electric bills first. Call (855) 657-3403 for a blower door test before you commit.
Can you spray foam over old fiberglass?
No, and any crew that says otherwise is cutting corners. We remove the old fiberglass, inspect the deck for moisture, and spray onto clean sheathing. Applying foam over settled fiberglass traps heat and moisture. The 90-Day Done Right Promise covers the full removal and reinstallation.
Blown-In Insulation in Alpharetta
Blown-in insulation is the most common fix for Alpharetta attics where the original 1990s fiberglass has settled to a fraction of its rated R-value. Homes in Deerfield, Windward, and Crabapple were typically insulated to R-30 at code minimum, but 25 years of compression and air movement drops real performance well below that. Loose-fill fiberglass from Owens Corning or Knauf, blown to a true R-49, is the most cost-effective way to restore the thermal boundary in a vented attic. Our Blown-In Insulation crew measures settled depth before quoting so you’re not paying to top up a problem that needs air sealing first.
Blown-In Fiberglass
Signs you need it
You can see the tops of the ceiling joists in the attic, or the insulation measures under 12 inches deep across most of the floor. In Alpharetta, original R-30 batts are almost always under-performing by year 20.
What it costs in Alpharetta
Blowing fiberglass to R-49 in a typical Alpharetta attic runs $1,800 to $3,500 depending on square footage and whether old material is removed first.
How we do it
We air seal the attic floor penetrations, mark the target depth, and blow loose-fill fiberglass to a consistent R-38 or R-49. The machine runs from the truck while a technician in the attic directs the hose.
Blown-In Top-Up
Signs you need it
Your attic has insulation in some areas but bare or thin patches near the eaves, or the existing material has settled several inches. A top-up is cheaper than removal when the existing material is dry and clean.
What it costs in Alpharetta
A top-up over existing insulation in Alpharetta runs $800 to $1,800 depending on current depth and target R-value.
How we do it
We check moisture content first. If the existing insulation is dry, we blow new fiberglass over it to reach the target depth, then card the surface level.
What Blown-In Insulation Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Blown-in fiberglass to R-49 (1,500 sq ft attic) | $1,800 - $3,500 |
| Top-up over existing insulation | $800 - $1,800 |
| Blown-in cellulose (per sq ft, installed) | $0.90 - $1.60 |
How much insulation does an Alpharetta attic need?
For Climate Zone 3A, the Department of Energy recommends R-38 to R-49 in vented attics. Most 1990s Alpharetta homes started at R-30 and have settled below that. We quote to R-49 on most attics because the labor is nearly the same. Call (855) 657-3403 and we’ll measure your current depth for free.
Does blown-in insulation settle over time?
Fiberglass settles less than cellulose, but both lose height over 20-plus years. Alpharetta attics with the original code-minimum install are almost always due for a top-up or full re-blow by now. Our estimate includes a measured depth check, not a guess.
Radiant Barrier Installation in Alpharetta
A radiant barrier does one job very well in Alpharetta: it stops the attic floor from radiating stored heat into the living space after the sun goes down. In July and August, the roof deck absorbs heat all day and then releases it through the fiberglass into the ceiling below. Stapling a reflective barrier to the underside of the rafters cuts that transfer significantly, and in Alpharetta’s 3A climate the best results come from pairing it with proper ventilation and air sealing. Our Radiant Barrier Installation process uses reinforced foil that holds up to the heat and humidity inside a Georgia attic.
Attic Radiant Barrier
Signs you need it
Your upstairs stays hot well past midnight in summer, or the ceiling itself feels warm to the touch. Heat radiating from the roof deck into the attic floor is the likely culprit.
What it costs in Alpharetta
Installing a radiant barrier across the rafters of a typical Alpharetta attic runs $1,500 to $3,000 depending on roofline complexity.
How we do it
We staple a reinforced foil barrier to the underside of the rafters, leaving a small air gap on each side for the reflective surface to work. In Alpharetta’s steep multi-plane roofs, we work section by section and keep the barrier taut.
Radiant Barrier & Ventilation
Signs you need it
The attic temp in summer is pushing 140°F and your ridge or soffit vents are undersized. A radiant barrier without enough airflow does far less than it should.
What it costs in Alpharetta
Adding or correcting soffit and ridge ventilation during a radiant barrier install in Alpharetta typically runs $600 to $1,400 extra.
How we do it
We verify existing vent area, add soffit baffles where needed, and confirm ridge or gable vents are moving air before installing the barrier. The foil reflects heat; ventilation carries it out.
What Radiant Barrier Installation Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Attic radiant barrier (1,500 sq ft attic) | $1,500 - $3,000 |
| Ventilation correction with barrier | $600 - $1,400 |
| Barrier plus attic air sealing | $2,300 - $4,200 |
Does a radiant barrier work in Alpharetta without extra insulation?
It helps, but it’s not a substitute. Alpharetta attics need both the reflective surface and adequate fiberglass or foam below. Used alone, a radiant barrier primarily cuts late-evening heat transfer. The real savings come from pairing it with air sealing and proper depth. Estimates are free at (855) 657-3403.
Will a radiant barrier damage my roof shingles?
No, in a properly ventilated Alpharetta attic, the barrier does not raise shingle temperature enough to matter. The barrier sits inside the attic on the rafters, not on the roof deck. Adequate soffit and ridge ventilation keeps the roof system within its normal temperature range.
Insulation Removal & Replacement in Alpharetta
Removing and replacing insulation is the right call when Alpharetta attics show rodent damage, moisture staining, or insulation that’s been compressed by years of foot traffic and roof leaks. A 25-year-old attic that’s hosted squirrels or roof rats in the tree-heavy subdivisions around Kimball Bridge and Crabapple needs material pulled before new insulation goes in. You don’t want fresh fiberglass layered over contaminated material, and in Alpharetta’s humid air, damp insulation keeps releasing moisture into the house. Our Insulation Removal & Replacement crew handles full extraction, sanitizing, and re-insulation in a single visit.
Attic Insulation Removal
Signs you need it
You see rodent droppings in the insulation, the material is matted and compressed, or a past roof leak left water damage across a section. Dry rot around roof penetrations is another sign that material needs to come out.
What it costs in Alpharetta
Full attic insulation removal in Alpharetta runs $2,000 to $4,500 depending on attic size, access, and contamination level.
How we do it
We run a HEPA-filtered vacuum from the truck to the attic, remove all old material down to the deck, and bag it for disposal. Technicians wear full PPE and seal off the attic access to keep dust out of the house.
Insulation Replacement
Signs you need it
The old insulation is gone or so degraded that topping up won’t fix the performance problem. Fresh blown-in or batt insulation is the path back to a stable thermal boundary.
What it costs in Alpharetta
Removal plus new blown-in fiberglass to R-49 in Alpharetta typically runs $3,800 to $8,000 all in.
How we do it
After the old material is vacuumed out, we air seal the attic floor, then blow in new fiberglass from Owens Corning or Johns Manville to the specified depth. Most jobs are completed in one visit.
What Insulation Removal & Replacement Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Full attic removal | $2,000 - $4,500 |
| Removal plus re-insulation to R-49 | $3,800 - $8,000 |
| Contaminated insulation removal (rodent damage) | $2,500 - $5,500 |
Is it cheaper to just blow over old insulation in Alpharetta?
Sometimes, but not when the old material is contaminated or wet. Layering over rodent-soiled or moldy insulation traps the problem under fresh material. We only recommend top-ups when the existing insulation is dry, clean, and structurally sound. Call (855) 657-3403 for an honest assessment.
How long does attic insulation removal take?
Most Alpharetta attics are fully vacuumed in half a day. The re-insulation can often happen the same afternoon, which is why we build most removal and replacement jobs as single-day visits. Your live person scheduler can confirm a same-week slot.
Attic Air Sealing in Alpharetta
Air sealing is the unglamorous half of attic work that Alpharetta homeowners skip and then regret. Every recessed light, ceiling fan box, top plate, and plumbing penetration lets conditioned air leak from the house into a 140°F attic. Sealing those leaks before adding insulation makes the new material perform at its rated R-value. In Alpharetta’s master-planned communities, the original builder work typically left dozens of unsealed penetrations, which is why we measure with a blower door before and after. The full process is documented on our Attic Air Sealing page.
Attic Floor Air Sealing
Signs you need it
You feel drafts in the hallway even with windows closed, or the upstairs is dusty despite regular cleaning. Air moving through the attic floor carries dust and humidity with it.
What it costs in Alpharetta
Sealing the attic floor penetrations in a typical Alpharetta home runs $900 to $1,800 depending on access and the number of bypasses.
How we do it
We pull back insulation in work sections, seal each penetration with fire-rated foam or caulk, and set the insulation back. Every seam around a top plate gets a continuous bead.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights in the ceiling feel warm, or airflow from a register is noticeably weaker than from others. Leaky duct boots quietly bleed conditioned air into the attic.
What it costs in Alpharetta
Sealing can lights and duct boots in Alpharetta runs $500 to $1,200 for a typical home, depending on how many fixtures and boots are accessible.
How we do it
We install rated covers over non-IC can lights, seal the covers to the drywall, and mastic-seal each duct boot to the ceiling and the duct collar. The difference in register airflow is often immediate.
What Attic Air Sealing Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Full attic floor air sealing | $900 - $1,800 |
| Can light and duct boot sealing | $500 - $1,200 |
| Attic hatch sealing and weatherstripping | $150 - $350 |
Can air sealing make my Alpharetta house too tight?
Not realistically. Alpharetta’s 1990s and 2000s homes leak far more air than a tight building envelope would. Sealing the attic floor, especially in homes with original construction, brings the air changes per hour down toward a healthy range. We test with a blower door to confirm.
Do I need air sealing before new insulation?
Yes, for the same reason you wouldn’t put on a down jacket over a wet shirt. Insulation slows conductive heat transfer but does little to stop air movement. In Alpharetta, sealing before blowing is the standard we follow on every attic job.
Wall Insulation in Alpharetta
Wall insulation doesn’t get the attention attic work does, but for Alpharetta homes with uninsulated interior walls or bonus room knee walls, it’s the difference between a usable room and a temperature swing. The bonus room over the garage pattern is the dominant wall insulation problem in this city: the garage ceiling below is thin, the knee walls are uninsulated, and the room bakes in summer. We insulate those cavities with injection foam or dense-pack fiberglass so the room holds temperature. See our Wall Insulation process for the full breakdown of interior and exterior options.
Injection Foam Wall Insulation
Signs you need it
Exterior walls feel cold to the touch in winter, or a specific room runs 5 degrees off from the rest of the house. Finished walls with empty cavities are prime candidates for injection foam.
What it costs in Alpharetta
Injecting foam into existing wall cavities in Alpharetta runs $3 to $5 per square foot of wall area, so a standard two-story wall section typically lands between $1,800 and $4,500.
How we do it
We drill small holes through the drywall or exterior sheathing, inject foam to fill the cavity, and patch the holes cleanly. The foam expands to seal gaps and stops air movement inside the wall.
Dense-Pack Wall Insulation
Signs you need it
Interior walls in a bonus room or over a garage feel hollow, and the room swings hot in summer and cold in winter. Dense-pack cellulose is the right fix for closed cavities.
What it costs in Alpharetta
Dense-packing existing walls in Alpharetta typically runs $2 to $4 per square foot of wall area, or $1,200 to $3,200 for an average bonus room.
How we do it
We drill access holes, blow cellulose at high pressure to fill each cavity completely, and patch. The finished wall feels solid and the room sits at a steadier temperature.
What Wall Insulation Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Injection foam (per sq ft of wall) | $3 - $5 |
| Dense-pack cellulose (per sq ft of wall) | $2 - $4 |
| Garage ceiling insulation | $900 - $1,800 |
Why is my bonus room over the garage so hot in Alpharetta?
Because the original builder didn’t insulate the knee walls or the garage ceiling below it. The room has a thermal break on three sides. We fix it by insulating the knee walls, sealing the floor joists, and adding material to the garage ceiling. Call (855) 657-3403 for a room-specific diagnosis.
Can you insulate walls without tearing out drywall?
Yes, that’s exactly how injection foam and dense-pack work. We make small access holes, fill the cavities, and patch cleanly. The drywall stays in place and the room is usable the same day. Most Alpharetta wall jobs finish in a single visit.
Attic Cleaning & Rodent Proofing in Alpharetta
Attic cleaning and rodent proofing in Alpharetta goes hand in hand with insulation because tree-heavy lots in neighborhoods like Windward and Crabapple put squirrels and roof rats right at roof level. Rodents tear into ductwork, chew wiring, and soak insulation with urine and droppings. We remove the contaminated material, sanitize the full attic floor, and close off every entry point so they can’t come back. The full service is detailed on our Attic Cleaning & Rodent Proofing page, and it’s always backed by the 90-Day Done Right Promise.
Attic Cleanout
Signs you need it
You hear scratching in the ceiling at dawn, or you’ve stored items in the attic that now show droppings and chew marks. Old insulation with rodent trails needs to come out.
What it costs in Alpharetta
A full attic cleanout with debris removal in Alpharetta runs $1,200 to $2,800 depending on contamination and attic size.
How we do it
We vacuum out the old insulation, bag debris, and remove damaged materials. The space is left clean and ready for new insulation or sealing. Technicians wear full PPE for the whole job.
Rodent Proofing & Exclusion
Signs you need it
You see entry holes at the roofline or where utility lines enter, or rodents keep returning after removal. Sealing the entry points is the only long-term fix.
What it costs in Alpharetta
Rodent proofing and exclusion on a typical Alpharetta home runs $700 to $1,800 depending on the number of entry points and roofline access difficulty.
How we do it
We inspect the full roofline, seal gaps with steel mesh and sealant, and screen gable and soffit vents. Then we set the attic for monitoring so any recurrence gets caught early.
What Attic Cleaning & Rodent Proofing Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Full attic cleanout | $1,200 - $2,800 |
| Rodent proofing and exclusion | $700 - $1,800 |
| Cleanout plus re-insulation | $3,000 - $6,500 |
Do I need to remove insulation after rodents in Alpharetta?
Yes, if the contamination is widespread. Rodent urine and droppings carry pathogens and the smell doesn’t dissipate on its own. Leaving the material means the odor and the health risk stay under your roof. We remove, sanitize, and replace in one visit. Call (855) 657-3403 to schedule an inspection.
Can you keep rodents out of my Alpharetta attic permanently?
We can, with a properly installed exclusion system. The key is sealing every entry point with materials rodents can’t chew through, which standard caulk and foam don’t do. We use steel mesh, hardware cloth, and professional-grade sealants on every job. The 90-Day Done Right Promise covers the exclusion work.

Home Energy Audit in Alpharetta
A home energy audit is the diagnostic step that makes every other insulation job in Alpharetta smarter. Instead of guessing why the upstairs is hot or the power bill spiked, we measure it with a blower door, thermal imaging, and duct testing. In Alpharetta’s large 3,500 to 6,000 square foot homes, the audit usually finds a mix of air leaks, duct losses, and settled insulation that interact in ways a walkthrough alone can’t catch. Our Home Energy Audit service gives you a prioritized fix list so you spend money where it moves the needle.
Blower Door Test
Signs you need it
Your home is drafty in winter, dusty year-round, or the AC runs constantly on hot afternoons. A blower door test quantifies how leaky the building envelope actually is.
What it costs in Alpharetta
A standalone blower door test in Alpharetta typically costs $200 to $400 as part of a full energy audit.
How we do it
We mount a calibrated fan in an exterior door frame, depressurize the house, and measure the airflow required to hold the pressure. That number tells us exactly how much air is moving through the shell.
Thermal Imaging Inspection
Signs you need it
Certain walls or ceilings always feel cold, or you suspect missing insulation but can’t confirm it without opening the wall. Thermal imaging shows the gaps clearly.
What it costs in Alpharetta
A thermal imaging scan during a home energy audit in Alpharetta runs $150 to $300, depending on square footage.
How we do it
We scan each ceiling and wall surface with an infrared camera while the blower door runs. Missing insulation, air leaks, and moisture show up as temperature anomalies we can pin to specific cavities.
What Home Energy Audit Costs in Alpharetta
| Item | Typical range in Alpharetta |
|---|---|
| Full home energy audit | $350 - $700 |
| Blower door test (standalone) | $200 - $400 |
| Thermal imaging scan | $150 - $300 |
| Duct leakage test | $150 - $300 |
Is a home energy audit worth it before insulating in Alpharetta?
Yes, especially in larger Alpharetta homes where the attic is broken into multiple zones and the ductwork runs through unconditioned space. The audit tells you whether the problem is insulation depth, air sealing, or ducts. Without it, you’re guessing which upgrade to buy first.
How long does a home energy audit take?
Most Alpharetta homes take 2 to 3 hours for a full

FAQs About Insulation in Alpharetta, GA
How quickly can you schedule an insulation job?
Scheduling depends on current demand and the scope of the work. After a quick phone call or an on-site look at the attic, crawl space, or walls involved, we set a start date for the Alpharetta job and let you know how long it will take before any work begins.
Do I need a permit for insulation work?
Routine insulation work usually doesn’t require a permit. We do size new material to current code rather than simply matching the code-minimum fiberglass that went into most homes here when they were originally built, since that original standard is lower than what’s recommended today.
How does the written estimate work?
Before any work starts, we walk the attic, crawl space, or walls being insulated and write up the exact scope and price for the Alpharetta job in a single document. That number is fixed before any material is opened or any tear-out begins, so there are no surprise add-ons once work is underway.
Which nearby areas do you also cover?
We also work throughout the surrounding area, including Houston, Spring, The Woodlands, Katy, Pearland, and Humble, and Alpharetta appointments are scheduled alongside jobs in those communities. If your home falls just outside this list, call and we’ll confirm whether we can reach you.
What happens to my old insulation when you replace it?
We remove old batts, blown-in material, or vapor barrier and bag or vacuum it out for disposal before any new insulation goes in. If it’s contaminated with rodent droppings, mold, or moisture damage, we handle it separately with sanitizing before the space is sealed and refilled.

What Alpharetta Customers Say
"Radiant barrier stapled to the rafters plus new baffles at the soffits. Attic temperature dropped enough that the AC runs noticeably less in the afternoon. Crew was in and out in a day and left the garage cleaner than they found it."
- Sam Kessler"Injection foam in the walls of our 1950s house - no drywall demolition, just small holes patched and painted the same day. The street noise in the front bedroom is half what it was."
- Yasmin Farah"Upstairs was ten degrees hotter than downstairs every summer. They pulled the attic to bare joists, air-sealed every can light and top plate first, then blew it to R-49. First August in this house where the bedrooms and the living room read the same on the thermostat."
