Insulation in Atlanta, GA
Crawl space encapsulation and vapor barrier work in Atlanta almost always starts with the same discovery: red Georgia clay holding moisture against pier foundations while batts of fiberglass sag from floor joists. Most crawl spaces we open in intown bungalows from the 1920s through 1940s haven’t been touched since the house went up. The fix is a sealed, conditioned crawl space, and the result is warmer floors, lower humidity, and an end to the damp smell that creeps into living space. Call (855) 657-3403 for a free estimate and we’ll tell you exactly what’s going on under your house.
Why Atlanta Homes Are Different
Atlanta’s insulation challenges start with the housing stock itself. Intown neighborhoods like Grant Park, Kirkwood, East Lake, and Reynoldstown are dense with Craftsman bungalows and shotgun homes built between the 1920s and 1940s. Those houses went up before wall insulation was standard, and many still have empty 2×4 stud bays or, if you’re unlucky, crumpled newspaper someone stuffed in there decades ago. Out in the post-war inner suburbs, you’ll find thousands of 1950s and 1960s ranch homes on crawl spaces or slabs, built to pre-energy-code standards that treated insulation as optional.
Climate Zone 3A is the other half of the story. Atlanta isn’t a purely hot city or a purely cold one. We design for real summer heat gain, real winter heating loads, and year-round humidity that pushes vapor through every unsealed gap it can find. The result is that the most useful work in Atlanta is almost always retrofit: dense-pack cellulose in old walls, encapsulation over damp clay, and attic air sealing on homes where ductwork roasts in 140-degree heat from June through September.
Our Main Atlanta Services
Two services get the most calls from Atlanta homeowners, and they’re the jobs this city’s housing stock demands most often. Here’s what each one looks like on the ground.
Attic Insulation in Atlanta
In an Atlanta summer, an unconditioned attic can hit 140°F before noon, and that heat pours straight down into living space when the attic floor is under-insulated. We address it with a full attic retrofit: assess existing R-value, air seal every penetration, then blow in fresh insulation to code for Zone 3A. Homes in Grant Park or East Lake with original ceiling joists respond well to blown-in cellulose over air sealing, which also quiets the house.

Crawl Space Encapsulation & Vapor Barrier in Atlanta
Crawl space encapsulation in Atlanta is the highest-impact retrofit most intown homeowners can make, because the combination of red clay soil, high relative humidity, and vented pier foundations creates a near-perfect moisture problem under floorboards. Encapsulation seals the crawl space with a heavy-duty vapor barrier, closes the vents, and conditions the space so moisture stops wicking up from the clay into floor joists and hardwood flooring. For full details on materials and the process, see our Crawl Space Encapsulation & Vapor Barrier page.
Crawl Space Vapor Barrier
Signs you need it
You smell must or damp when you walk into the house, floors feel humid in summer, or you can see exposed dirt with a thin, torn sheet of plastic that’s curling at the seams.
What it costs in Atlanta
Expect to pay roughly $2.50 to $5 per square foot depending on the barrier thickness, access difficulty, and whether piers need sealing.
How we do it
We clean the crawl space floor, lay a 12-mil or thicker liner across the entire footprint, run it up the foundation walls, and mechanically fasten it at the top. All seams are taped and pier bases are sealed so nothing wicks through.
Crawl Space Encapsulation
Signs you need it
Your floorboards feel damp or cupped in summer, you see condensation on ductwork under the house, or your energy bills spike when the AC runs hardest.
What it costs in Atlanta
Full encapsulation in Atlanta typically runs $3 to $7 per square foot, which includes the liner, sealing, ventilation changes, and a dehumidifier where the space needs one.
How we do it
We seal every vent and penetration, install the vapor barrier from floor to foundation wall, run closed-cell foam on the rim joist, and add a correctly sized dehumidifier. The result is a dry, conditioned space that stops pulling humid outside air under your house.
Crawl Space Insulation
Signs you need it
Floors over the crawl space are cold in winter, pipes have frozen or come close, or old fiberglass batts are sagging and wet against the subfloor.
What it costs in Atlanta
Spray foam on the rim joist and foundation walls usually lands between $3 and $7 per square foot when done as part of an encapsulation job.
How we do it
For encapsulated crawl spaces, we insulate the foundation walls rather than the floor joists, using closed-cell foam on the rim and rigid board or foam on the walls. The crawl space becomes part of the conditioned envelope, which keeps your floors warmer and your ducts cooler.
What Crawl Space Encapsulation & Vapor Barrier Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Vapor barrier (12-mil+) | $2.50 - $5 per sq ft |
| Full encapsulation | $3 - $7 per sq ft |
| Rim joist spray foam | $3 - $7 per sq ft |
| Crawl space dehumidifier (if needed) | $2,500 - $4,000 installed |
Can you encapsulate a crawl space in Atlanta’s humidity?
Yes, and Atlanta’s humidity is exactly why encapsulation works. A properly installed vapor barrier and sealed vents stop humid outside air from entering, and a dehumidifier controls whatever moisture remains. The sealed space stays drier than the outside air year-round.
Is a dehumidifier required in an encapsulated crawl space?
In most Atlanta homes, yes. With clay soil and a high water table in parts of the metro, passive drying isn’t reliable. We size a dehumidifier to the crawl space’s volume and place it where air circulates across the barrier.
Spray Foam Insulation in Atlanta
Spray foam insulation changes the equation in Atlanta, because it air-seals as it insulates. In older intown homes with balloon framing and gaps that have never been closed, open-cell foam fills and seals in one pass; on rim joists and foundation walls, closed-cell foam adds a moisture and vapor barrier that stops the wet-clay problem cold. For a deep dive on foam chemistry and the brands we install, see our Spray Foam Insulation page.
Open-Cell Spray Foam
Signs you need it
Your attic reaches 140°F in summer, upstairs rooms won’t cool, or you hear every outside noise through the roof deck.
What it costs in Atlanta
Open-cell foam typically runs $0.40 to $2.75 per board foot depending on depth; most Atlanta attic roof deck jobs fall in the middle of that range.
How we do it
We prep the roof deck, spray open-cell foam to the target R-value for Zone 3A, and leave it exposed or cover it per code. The foam expands to fill every gap, which is what makes it so effective in old Atlanta houses.
Closed-Cell Spray Foam
Signs you need it
You need insulation with a built-in vapor barrier, you have a rim joist over a damp crawl space, or you want higher R-value per inch than any batt can deliver.
What it costs in Atlanta
Closed-cell foam costs $0.65 to $4.50 per board foot in Atlanta; the higher end applies to thick roof deck or unusual geometry work.
How we do it
We spray one to three inches to hit the target R-value, then leave the cured foam as both insulation and air barrier. On rim joists we work in tight passes so the foam bonds fully to wood and masonry.
Rim Joist Spray Foam
Signs you need it
Your crawl space is cold in winter and humid in summer, or you’ve seen mouse droppings and debris where the joists meet the foundation.
What it costs in Atlanta
Rim joist foam in Atlanta runs $3 to $7 per square foot when measured across the joist area being sealed.
How we do it
We clean the rim joist, seal visible gaps, and spray closed-cell foam in a continuous band. This is a standard part of our encapsulation work because it closes the single biggest air leak in most Atlanta crawl spaces.
What Spray Foam Insulation Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Open-cell foam (per board foot) | $0.40 - $2.75 |
| Closed-cell foam (per board foot) | $0.65 - $4.50 |
| Rim joist closed-cell sealing | $3 - $7 per sq ft |
| Attic roof deck (open-cell, full) | $2,500 - $9,000+ |
Is spray foam worth it in Atlanta’s climate?
For many homes, yes. The air-sealing benefit matters more here than in drier cities, because it stops humid outside air from entering through the same gaps heat escapes through. It also keeps attic ductwork cooler, which matters when attics hit 140°F.
Can you spray foam an old Atlanta bungalow attic?
Yes, and those attics are often ideal candidates. We inspect the roof deck first for any signs of water damage, then spray the underside to turn the attic into conditioned space or add a ventilated air gap where plans call for it.
Blown-In Insulation in Atlanta
Blown-in insulation is the workhorse retrofit for Atlanta’s older homes, because it can fill wall cavities and attic floors without opening walls. In Grant Park and Kirkwood bungalows where original wall cavities are empty or packed with newspaper, dense-pack cellulose goes in through small holes and delivers real R-value in a day. On attic floors, we blow over existing settled insulation after air sealing. For the full breakdown of materials and typical jobs, see our Blown-In Insulation page.
Blown-In Cellulose
Signs you need it
Your attic floor has thin or settled insulation, upstairs rooms run hot in summer, or your walls feel hollow when you knock on them.
What it costs in Atlanta
Blown-in cellulose in Atlanta runs $1.25 to $2.75 per square foot for attic floors, with dense-pack wall jobs at $2 to $5 per square foot depending on access and depth.
How we do it
We use cellulose from GreenFiber or similar blower-grade product, install to the exact depth for the target R-value, and blow it through small access holes in walls. The material settles slightly, so we over-blow to spec.
Dense-Pack Wall Insulation
Signs you need it
You live in a 1920s-1940s intown home with empty wall cavities, rooms that won’t hold temperature, or original plaster over lathe that you don’t want to tear out.
What it costs in Atlanta
Dense-pack cellulose in Atlanta typically runs $2 to $5 per square foot of wall area, including the access holes and patching.
How we do it
We drill small holes through siding or drywall, blow cellulose at high density until the cavity is packed, then patch each hole to match. The result is a filled, insulated cavity you’d never know was opened.
Attic Blown-In Top-Up
Signs you need it
Your attic insulation is present but below the Zone 3A recommended level, or you can see the tops of ceiling joists across the floor.
What it costs in Atlanta
A blown-in top-up over existing insulation in Atlanta runs $1.25 to $2.75 per square foot depending on how much material is needed to reach target R-value.
How we do it
We check the existing insulation, add blown-in product to reach the target depth, and keep the attic vents clear so air still moves. This is the quickest single-visit insulation job we do in Atlanta.
What Blown-In Insulation Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Attic floor cellulose | $1.25 - $2.75 per sq ft |
| Dense-pack wall cellulose | $2 - $5 per sq ft |
| Attic top-up over old insulation | $1.25 - $2.75 per sq ft |
| Blown-in fiberglass (attic) | $0.75 - $2 per sq ft |
Can you blow insulation into old Atlanta walls without tearing out plaster?
Yes. We drill access holes through siding or drywall, blow dense-pack cellulose into each cavity, then seal the holes. The process preserves original plaster and trim, which matters in bungalows and historic intown homes.
How much insulation do Atlanta attics need?
Zone 3A calls for roughly R-38 to R-49 in the attic floor. Many older Atlanta homes have R-9 to R-13, so a top-up makes a measurable difference in cooling bills from the first summer.
Radiant Barrier Installation in Atlanta
Radiant barrier installation in Atlanta targets the single biggest summer heat load in this city: an asphalt shingle roof deck that overheats to 140°F and radiates heat down into the attic. A radiant barrier stapled or laid across the roofline and attic floor cuts that radiant transfer and drops attic temperatures by double digits. For the material specs and typical layouts, see our Radiant Barrier Installation page.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms won’t cool below 80°F on hot days, the attic is unbearable by mid-afternoon, or your AC runs nonstop from June through September.
What it costs in Atlanta
Attic radiant barrier in Atlanta runs $0.75 to $1.50 per square foot when installed on the roof deck or attic floor.
How we do it
We staple a perforated radiant barrier to the underside of the roof rafters or lay it across the attic floor, leaving a small air gap on one side. The foil reflects heat back toward the roof deck instead of letting it radiate into the attic.
Radiant Barrier & Ventilation
Signs you need it
You have a radiant barrier or plan to get one, your attic has inadequate or blocked vents, or you’ve found signs of moisture in an attic that runs hot.
What it costs in Atlanta
Radiant barrier with ventilation correction in Atlanta runs $0.75 to $1.50 per square foot for the barrier plus the cost of vent work, which we quote separately after inspection.
How we do it
We check that soffit and ridge ventilation are balanced before installing the barrier, then add venting where needed. A radiant barrier without proper airflow can trap moisture in a humid climate, so we treat the two as one job.
What Radiant Barrier Installation Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Attic radiant barrier (roof deck) | $0.75 - $1.50 per sq ft |
| Attic floor radiant barrier | $0.75 - $1.50 per sq ft |
| Radiant barrier + ventilation correction | Quoted after inspection |
| Combined barrier + attic air sealing | $2,000 - $4,500+ |
Does a radiant barrier work in Atlanta’s climate?
Yes, and it works well in a humid-subtropical climate because the benefit is about blocking radiant heat, not controlling air. It reduces attic temperatures meaningfully in summer, which lowers the cooling load and takes strain off ductwork.
Will a radiant barrier replace attic insulation?
No. A radiant barrier reduces radiant heat gain, but it does not resist conductive heat transfer the way insulation does. We recommend radiant barrier in addition to proper attic insulation, not instead of it.
Insulation Removal & Replacement in Atlanta
Insulation removal and replacement in Atlanta almost always starts with a problem: rodents, old contaminated material, water damage, or attic insulation so settled it’s no longer doing anything. We remove the failed material, sanitize where needed, and reinstall insulation sized for Zone 3A. For the process and pricing details, see our Insulation Removal & Replacement page.
Contaminated Insulation Removal
Signs you need it
You’ve seen rodent droppings, nests, or trails in the attic, or you’re removing insulation after a roof leak that soaked the material and left mold or mildew.
What it costs in Atlanta
Contaminated insulation removal in Atlanta runs $2 to $4.50 per square foot depending on access, depth, and whether sanitation is included.
How we do it
We contain the work area, vacuum out the failed insulation, bag it, and sanitize the surfaces underneath. Then we inspect for entry points and recommend sealing before new insulation goes in.
Attic Insulation Removal
Signs you need it
The attic is full of old, thin, or pest-damaged material, or you’re about to do air sealing and don’t want old debris in the way.
What it costs in Atlanta
Plain attic insulation removal in Atlanta runs $1.50 to $3 per square foot when no contamination cleanup is needed.
How we do it
We bring a commercial HEPA vacuum and bagging system, remove the old material by hand or suction, and leave the attic floor ready for air sealing and new blown-in insulation.
Insulation Replacement
Signs you need it
Your insulation is gone, wet, or so old it no longer meets code, and you want a clean start with modern material.
What it costs in Atlanta
Insulation replacement in Atlanta runs $1.25 to $5 per square foot depending on the material chosen and whether it’s an attic, crawl space, or wall cavity.
How we do it
After removal and any needed repairs, we install new insulation to the target R-value for the space, using blown-in, batt, or spray foam depending on where it’s going and the house’s construction.
What Insulation Removal & Replacement Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Attic insulation removal (clean) | $1.50 - $3 per sq ft |
| Contaminated insulation removal | $2 - $4.50 per sq ft |
| Attic removal + new blown-in | $3 - $7 per sq ft |
| Sanitizing after rodent damage | $1 - $3 per sq ft |
How do you know if attic insulation needs replacement in Atlanta?
Look for pest droppings, water stains on the material or decking, or insulation that sits well below the joist tops. If any of the three are present, removal and replacement beats top-up because it eliminates contamination before new material goes in.
Can old insulation stay in place under new insulation?
Sometimes, but not if it’s wet, pest-contaminated, or moldy. Clean, dry, settled insulation can be topped up. We’ll inspect before we recommend removal, because we won’t cover a problem that should have been fixed first.
Attic Air Sealing in Atlanta
Attic air sealing in Atlanta is the least visible upgrade with the biggest comfort payoff, especially in intown bungalows where dozens of original penetrations let conditioned air leak into a 140°F attic all summer. We seal top plates, can lights, duct boots, hatch frames, and every penetration we can reach from above. For the full air sealing process and materials, see our Attic Air Sealing page.
Attic Floor Air Sealing
Signs you need it
Rooms below the attic are drafty, dust falls through ceiling fixtures, or your AC bill is high even with recent insulation work.
What it costs in Atlanta
Attic floor air sealing in Atlanta runs $0.75 to $2.50 per square foot of attic area being sealed.
How we do it
We pull back the insulation around each penetration, seal the gap with the right material, and set the insulation back. This is done before new blown-in insulation goes on top.
Top Plate & Penetration Sealing
Signs you need it
You can see gaps around the top of wall plates, plumbing vents, wiring runs, or chimneys from the attic side, or you’ve noticed dust streaks on ceiling areas.
What it costs in Atlanta
Top plate and penetration sealing in Atlanta runs $0.75 to $2.50 per square foot when quoted across the attic floor area.
How we do it
We seal every opening with fire-rated foam or caulk as the material demands, with special attention to the joint between drywall and framing. On balloon-framed bungalows, that single joint is often the biggest leak in the house.
Can Light & Duct Boot Sealing
Signs you need it
You have recessed lights that get hot, conditioned air is leaking into duct chases, or you’ve noticed air streaming through gaps around ceiling registers.
What it costs in Atlanta
Can light and duct boot sealing in Atlanta typically runs $15 to $50 per fixture or boot, with the total depending on how many you’re sealing.
How we do it
For sealed-rated lights we caulk the trim ring; for non-sealed lights we add covers or replace the housing. Duct boots get sealant at the drywall joint and foam around the boot where it meets the trunk line.
What Attic Air Sealing Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Attic floor air sealing | $0.75 - $2.50 per sq ft |
| Top plate & penetration sealing | $0.75 - $2.50 per sq ft |
| Can light sealing (per fixture) | $15 - $50 per fixture |
| Attic hatch sealing | $75 - $200 per hatch |
Why is air sealing important in Atlanta before adding insulation?
Because blown-in insulation does almost nothing to stop air movement. In an Atlanta attic that reaches 140°F, every unsealed penetration pulls hot, dusty air into the house. Sealing first is what makes the insulation you pay for actually perform.
How long does attic air sealing take in an Atlanta home?
Most single-family Atlanta homes are sealed in four to eight hours. Our technicians work top-down, seal every penetration, then verify with a blower door or thermal scan where the audit includes one.
Wall Insulation in Atlanta
Wall insulation in Atlanta is the retrofit the city’s Craftsman bungalows have needed for a century. When we open an intown wall and find empty 2×4 bays or newspaper packing, the fix is dense-pack cellulose or injection foam that fills the cavities without tearing out plaster or siding. For the full menu of wall insulation options, see our Wall Insulation page.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel warm in summer and cold in winter, or you live in a 1920s-1940s Atlanta bungalow with original uninsulated walls.
What it costs in Atlanta
Injection foam wall insulation in Atlanta runs $2.50 to $5.50 per square foot of wall area depending on cavity depth and access.
How we do it
We drill small holes through siding or interior finish, inject expanding foam into each stud bay, and patch the holes to match. The foam fills every gap, which is ideal for lath-and-plaster bungalow walls with irregular cavities.
Drill & Fill Wall Insulation
Signs you need it
You want wall insulation without major renovation, your stud bays are open or accessible, or you’re in an older Atlanta home where the walls were never filled.
What it costs in Atlanta
Drill and fill wall insulation in Atlanta runs $2 to $5 per square foot, using either cellulose or fiberglass dense-pack material.
How we do it
We drill into each stud bay, blow material until the cavity is packed, and patch the holes. This is the most common wall retrofit in Atlanta’s post-war ranches as well as intown bungalows.
Interior Wall Soundproofing
Signs you need it
You can hear conversations or TV through interior walls, or you have a home office, bedroom, or guest room that needs acoustic isolation.
What it costs in Atlanta
Interior wall soundproofing in Atlanta runs $2.50 to $5.50 per square foot, with material choice driven by how much sound reduction you need.
How we do it
We either blow dense-pack into the cavity or install specialized batt products, depending on the wall’s construction. For the best result we pair the insulation with acoustical caulk on the drywall joints.
What Wall Insulation Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Injection foam walls | $2.50 - $5.50 per sq ft |
| Drill & fill cellulose walls | $2 - $5 per sq ft |
| Interior soundproofing | $2.50 - $5.50 per sq ft |
| Exterior wall insulation (new build) | $1.50 - $4 per sq ft |
Can you insulate walls in an old Atlanta bungalow without tearing out plaster?
Yes. Drill and fill is designed exactly for that. We go through the siding or through small interior holes, pack the cavity, and patch to match. In most cases there’s no drywall or plaster repair beyond the drill holes themselves.
Which wall insulation is best for Atlanta’s climate?
For existing walls, dense-pack cellulose or injection foam both work well in Zone 3A. Cellulose is cost-effective and fills irregular cavities. Injection foam air-seals as it insulates, which matters in houses where the wall cavities are tied to the attic and crawl space.
Attic Cleaning & Rodent Proofing in Atlanta
Attic cleaning and rodent proofing in Atlanta goes hand in hand with insulation, because rodents love the same old attics where insulation has settled. Squirrels, roof rats, and mice get into intown bungalows through rooflines, gable vents, and gaps around chimneys, and what they leave behind is contaminated material that has to go. For the full cleaning, sanitizing, and exclusion process, see our Attic Cleaning & Rodent Proofing page.
Attic Cleanout
Signs you need it
You can see rodent droppings, nesting material, or damaged insulation from a quick attic look, or you’ve heard animals moving above the ceiling.
What it costs in Atlanta
Attic cleanout in Atlanta runs $2 to $4.50 per square foot depending on the amount of material removed and whether contamination cleanup is included.
How we do it
We bag and remove the contaminated insulation, vacuum up debris and droppings, and leave the attic floor clean and ready for new material. The job usually takes a day.
Attic Sanitizing & Decontamination
Signs you need it
You’ve had rodents or bats, there are droppings over a large portion of the attic, or an old leak left musty smells in the framing.
What it costs in Atlanta
Attic sanitizing and decontamination in Atlanta runs $1 to $3 per square foot over the area being treated, on top of any cleanout work.
How we do it
After removal, we fog or spray an EPA-registered sanitizer across the attic surfaces and let it dry. The goal is a clean substrate for new insulation, not just a surface that looks clean.
Rodent Proofing & Exclusion
Signs you need it
You hear scurrying overhead at dawn or dusk, you find droppings or chewed wires, or you want to keep animals out after a cleanout.
What it costs in Atlanta
Rodent proofing and exclusion in Atlanta runs $300 to $1,500 depending on the number of entry points and the materials needed to close them.
How we do it
We inspect every potential entry: roof returns, gable vents, soffit gaps, chimney chases, and plumbing penetrations. Then we close them with steel mesh, hardware cloth, and sealant that animals cannot chew through.
What Attic Cleaning & Rodent Proofing Costs in Atlanta
| Item | Typical range in Atlanta |
|---|---|
| Attic cleanout (standard) | $2 - $4.50 per sq ft |
| Attic sanitizing & decontamination | $1 - $3 per sq ft |
| Rodent proofing & exclusion | $300 - $1,500 |
| Cleanout + new blown-in insulation | $4 - $8 per sq ft |
Do I need to replace insulation after rodent activity in Atlanta?
Usually yes. Rodent droppings and urine contaminate the material in ways that can’t be spot-cleaned. In an Atlanta attic where summer heat bakes that contaminated material, removing it before adding new insulation is the only approach we recommend.
How do rodents get into Atlanta attics?
Through roof returns, gable vents with loose screening, soffit gaps, chimney chases, and any opening larger than a dime. Older intown homes with original trim and multiple roof angles tend to have more potential entry points, so exclusion is a critical final step.

FAQs About Insulation in Atlanta, 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 Atlanta 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 typically doesn’t require a permit. This area sits in Climate Zone 3A, which calls for real summer heat gain control and winter heating performance in the same house, so we size new attic and wall material to that dual standard rather than a single-season minimum.
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 Atlanta 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 Atlanta 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 Atlanta Customers Say
"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez"The estimate had every line itemized - removal, sealing, baffles, the blown-in by the bag - and the final invoice matched it exactly. Two other companies quoted a single number and could not tell me what R-value they were installing."
- Priya Raman"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
