Insulation in Decatur, GA
Most Decatur homes need insulation work that goes well beyond a simple attic top-up. The city’s pre-WWII craftsman bungalows and 1950s-60s ranches sit on crawl spaces and pier-and-beam foundations, which means conditioned air leaks through floors, ductwork, and unsealed rim joists year-round. Crawl space encapsulation and vapor barrier work solves the biggest hidden energy loss in these older Decatur houses. Call (855) 657-3403 and a live person answers 24/7, ready to schedule a free estimate.
Why Decatur Homes Are Different
Decatur sits in ASHRAE Climate Zone 3A, a mixed-humid climate where summer cooling dominates but winter heating still matters. That combination punishes under-insulated homes twice: hot, humid air pushes into wall cavities and attics from June through September, then cold snaps force furnaces to run against poorly sealed building envelopes all winter. The dense tree canopy in neighborhoods like Oakhurst and Winnona Park shades roofs but holds humidity against the structure, turning crawl spaces into condensation traps.
The housing stock compounds the problem. Homes in Oakhurst, 2nd Avenue, and Winnona Park from the 1920s-1940s often have balloon-framed walls with zero original insulation. Attics in those bungalows may hold compressed fiberglass batts flattened to near-zero R-value, or vermiculite, a material from that era that can contain asbestos. The 1950s-70s ranch stock adds pier-and-beam crawl spaces where unsealed vents let humid outside air circulate around HVAC ductwork, bleeding conditioned air into the ground space. In Decatur’s pre-1950 homes specifically, contractors frequently find live knob-and-tube wiring in attic cavities. Georgia code prohibits covering that wiring with insulation until an electrician signs off, so a simple attic top-up often pauses for an electrical upgrade first. Out-of-town bidding crews consistently miss this.
Our Main Decatur Services
Two services draw the most calls from Decatur homeowners because they address the worst energy losses in this housing stock first. Here’s what each one involves locally.
Attic Insulation in Decatur
Decatur attics lose more conditioned air than any other part of the house, especially in bungalows where old batts have compressed or settled. We remove what’s failed, air seal the floor, and blow in new insulation to the correct depth for Climate Zone 3A. The older the home, the more likely the attic needs electrical clearance before insulation goes in, and we coordinate that step so the project doesn’t stall. Read the full breakdown on our Attic Insulation in Decatur page.

Crawl Space Encapsulation & Vapor Barrier in Decatur
Crawl space encapsulation in Decatur addresses the single worst basement-level energy problem in the city’s older housing stock: open, vented crawl spaces under pier-and-beam homes that pull humid outside air across HVAC ducts and into the house. Most homes in Oakhurst, Winnona Park, and 2nd Avenue sit on exactly this foundation type, and those crawl spaces stay damp and musty for months after every rain. Sealing and conditioning that space cuts humidity, stops duct condensation, and keeps the first floor warmer in winter. Our work uses reinforced vapor barrier material and is backed by the 90-Day Done Right Promise, because if it isn’t right, we make it right. Learn more about the full Crawl Space Encapsulation & Vapor Barrier service.
Crawl Space Vapor Barrier
Signs you need it
Standing water after heavy rain, visible moisture on foundation walls, or a musty smell rising through the first floor.
What it costs in Decatur
Vapor barrier installation in Decatur typically runs $3 to $5 per square foot including materials and sealing.
How we do it
We lay reinforced polyethylene sheeting across the crawl space floor and up foundation walls, then seal all seams and penetrations.
Crawl Space Encapsulation
Signs you need it
Humidity readings above 60 percent, sweating ducts, or hardwood floors cupping and warping in summer.
What it costs in Decatur
Full encapsulation in Decatur usually costs between $5,000 and $15,000 depending on square footage, access, and existing drainage.
How we do it
We seal every vent, install a full vapor barrier, add insulation to walls or rim joists, and run a dehumidifier sized to the crawl space volume.
Crawl Space Insulation
Signs you need it
Cold floors in winter, high heating bills, or visible exposed fiberglass falling from floor joists into the crawl space.
What it costs in Decatur
Insulating crawl space walls and rim joists with rigid foam or closed-cell spray typically runs $2,500 to $7,000 in Decatur homes.
How we do it
We air seal the rim joist bays and install insulation rated for ground-contact use, so it won’t absorb moisture or sag.
What Crawl Space Encapsulation & Vapor Barrier Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Vapor barrier only | $3 – $5 per sq ft |
| Full encapsulation | $5,000 – $15,000 |
| Crawl space insulation | $2,500 – $7,000 |
| Moisture control package | $1,500 – $4,000 |
How long does crawl space encapsulation take in Decatur?
Most Decatur crawl space encapsulations finish in one to two days. Pier-and-beam access, existing moisture damage, and whether we’re adding insulation or a dehumidifier all affect timeline. Call (855) 657-3403 to schedule an on-site assessment.
Will encapsulation fix my high humidity in Decatur summers?
Yes, properly installed encapsulation cuts crawl space humidity dramatically, often below 60 percent, which stops condensation on ducts and reduces first-floor humidity. The dense tree canopy in Decatur neighborhoods keeps ground moisture high, making the vapor barrier essential. Estimates are free.
Spray Foam Insulation in Decatur
Spray foam in Decatur works hardest in the city’s older homes, where balloon-framed walls and vented attics leak conditioned air through hundreds of invisible gaps. Closed-cell foam adds structural strength and acts as a vapor retarder, which matters in Climate Zone 3A’s humid summers. Open-cell foam is often the better choice for attic roof decks. We carry Icynene and Demilec products and back the installation with the 90-Day Done Right Promise. See the full Spray Foam Insulation service.
Open-Cell Spray Foam
Signs you need it
High cooling bills, uneven upstairs temperatures, or attic rooms that never hold comfortable air in summer.
What it costs in Decatur
Open-cell spray foam in Decatur attics and walls typically costs $1.50 to $2.50 per board foot installed.
How we do it
We spray foam directly onto the roof deck or wall cavities, forming an air seal that stops convection and quiets the house.
Closed-Cell Spray Foam
Signs you need it
Foundation walls that leak air and moisture, or crawl space rim joists that need rigid, water-resistant insulation.
What it costs in Decatur
Closed-cell spray foam in Decatur typically runs $2.50 to $4.00 per board foot installed.
How we do it
We apply foam at the correct thickness to create an air and vapor barrier that also adds racking strength to walls.
Rim Joist Spray Foam
Signs you need it
Drafty floors at the perimeter of every room, or cold spots along exterior walls in winter.
What it costs in Decatur
Rim joist sealing and spray foam at the band board usually costs $800 to $2,500 for a typical Decatur ranch.
How we do it
We seal each rim joist bay with closed-cell foam, cutting air infiltration where the floor meets the foundation.
What Spray Foam Insulation Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Open-cell spray foam | $1.50 – $2.50 / board ft |
| Closed-cell spray foam | $2.50 – $4.00 / board ft |
| Rim joist spray foam | $800 – $2,500 |
| Attic roof deck foam | $3,000 – $8,000 |
Is spray foam safe in older Decatur homes?
Yes, when installed by a licensed crew. We follow manufacturer cure times and ventilate the work area before anyone re-enters. The spray foam itself off-gasses quickly and becomes inert once cured. Call (855) 657-3403 with questions about a specific space.
Can you spray foam the roof deck in a 1920s Decatur bungalow?
Usually, yes. We inspect the roof sheathing and any knob-and-tube wiring first, because foam cannot cover live electrical lines. If the sheathing is sound and wiring is clear, we spray the roof deck to create a conditioned attic. Estimates are free.
Blown-In Insulation in Decatur
Blown-in insulation in Decatur is the fastest way to bring an older attic up to modern thermal performance without tearing into finished surfaces. Loose-fill cellulose or fiberglass fills every irregular cavity in those pre-war bungalows better than batts ever could. We typically install Owens Corning or GreenFiber products, chosen for their settled R-value and resistance to air movement. Read the full Blown-In Insulation service.
Blown-In Cellulose
Signs you need it
Attic insulation depth below 6 inches, high cooling bills in summer, or rooms directly under the roof that won’t hold temperature.
What it costs in Decatur
Blown-in cellulose in Decatur attics typically costs $1.50 to $3.00 per square foot installed to R-38 or R-49.
How we do it
We dense-pack or loose-fill cellulose from recycled paper treated with borate, filling every joist bay and corner cavity evenly.
Blown-In Fiberglass
Signs you need it
Compressed or damaged old batts, rodent contamination, or insulation that has settled below the top of the ceiling joists.
What it costs in Decatur
Blown-in fiberglass in Decatur usually runs $1.00 to $2.50 per square foot installed.
How we do it
We remove failed material when needed, air seal penetrations, then blow fiberglass to an even depth verified by ruler at multiple points.
Dense-Pack Wall Insulation
Signs you need it
Rooms with exterior walls that feel cold in winter or heat up fast in summer, in homes built before wall insulation was standard.
What it costs in Decatur
Dense-pack wall insulation in Decatur typically costs $3,000 to $8,000 for a whole bungalow depending on wall count and access.
How we do it
We drill small holes through siding or drywall, dense-pack cellulose into the cavities, then patch each hole cleanly.
What Blown-In Insulation Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Blown-in cellulose attic | $1.50 – $3.00 / sq ft |
| Blown-in fiberglass attic | $1.00 – $2.50 / sq ft |
| Dense-pack walls | $3,000 – $8,000 |
| Blown-in top-up | $800 – $2,000 |
How deep should attic insulation be in Decatur?
For Climate Zone 3A, we blow to R-38 at minimum, which is about 12 to 14 inches of cellulose, and R-49 where the roof allows. Most Decatur bungalows are currently at R-11 or less. Call (855) 657-3403 for a free attic assessment.
Can you blow insulation over existing batts in a Decatur attic?
Yes, in many cases we blow loose-fill directly over sound, uncontaminated batts to reach target depth. If the old material is compressed, damp, or rodent-damaged, we remove it first rather than bury a problem. Estimates are free.
Radiant Barrier Installation in Decatur
Radiant barriers in Decatur reduce the heat load that beats down on attic floors from late spring through early fall, which is exactly when the city’s dense tree canopy traps humidity and makes attics feel like ovens. A foil radiant barrier reflects radiant heat before it soaks into insulation, where it becomes conductive heat that radiates down into living spaces. That’s a real difference in the hottest Decatur afternoons. Explore the full Radiant Barrier Installation service.
Attic Radiant Barrier
Signs you need it
Upstairs rooms that stay 8 to 10 degrees hotter than downstairs in summer, or an attic that’s unbearable to enter after noon.
What it costs in Decatur
Installing a radiant barrier across the attic floor or rafters in Decatur typically costs $1,500 to $3,500.
How we do it
We staple double-sided foil across the underside of rafters or over existing insulation, leaving the required air gap for reflection.
Radiant Barrier Foil
Signs you need it
High air conditioning runtimes, hot ceilings, or wanting to protect attic-stored items from heat damage.
What it costs in Decatur
Foil radiant barrier material and installation in Decatur attics usually costs $0.75 to $1.50 per square foot.
How we do it
We measure and cut foil to fit each rafter bay, securing it with staples and foil tape at every seam.
Radiant Barrier Roof Deck
Signs you need it
A home with ductwork in the attic that must stay as cool as possible, or a roof that bakes in direct sun most days.
What it costs in Decatur
Roof deck radiant barrier installation in Decatur typically runs $2,000 to $5,000 depending on roof area and access.
How we do it
We attach the foil product to the underside of the roof decking, reflecting radiant heat before it enters the attic air space.
What Radiant Barrier Installation Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Attic radiant barrier | $1,500 – $3,500 |
| Radiant barrier foil | $0.75 – $1.50 / sq ft |
| Roof deck radiant barrier | $2,000 – $5,000 |
| Radiant barrier + ventilation | $2,500 – $6,000 |
Does a radiant barrier help in Decatur’s humid summers?
Yes, a radiant barrier keeps attic temperatures down during the long cooling season, which reduces heat gain into your ductwork and ceiling. It works alongside insulation, not instead of it. Call (855) 657-3403 to discuss whether your attic is a good candidate.
Do I still need attic insulation if I add a radiant barrier in Decatur?
Yes. The radiant barrier reflects radiant heat, but insulation is what resists conductive and convective heat transfer. In Decatur’s mixed-humid climate, you need both for year-round performance. Estimates are free.
Insulation Removal & Replacement in Decatur
Removal and replacement in Decatur is common work because the city’s older homes often hold insulation that has failed, been contaminated, or contains material that shouldn’t stay in place. Rodent activity, roof leaks, and decades of settling leave batts useless, while some pre-war Decatur attics still contain vermiculite that may include asbestos. We handle that carefully and legally. See the full Insulation Removal & Replacement service.
Attic Insulation Removal
Signs you need it
Visible compression, water stains, or old batts that have sagged and separated from each joist bay.
What it costs in Decatur
Attic insulation removal in Decatur typically costs $1.50 to $3.00 per square foot including bagging and disposal.
How we do it
We vacuum or bag existing insulation, clean the attic floor, and prepare the space for new material or air sealing.
Vermiculite & Old Insulation Removal
Signs you need it
Pebble-like gray or brown insulation in a pre-1970 Decatur attic, or any material you suspect predates current safety standards.
What it costs in Decatur
Suspected vermiculite removal in Decatur is quoted on inspection, but runs $4 to $8 per square foot when abatement is required.
How we do it
We stop work, seal the area, and coordinate with a licensed asbestos professional if testing confirms vermiculite is present.
Insulation Replacement
Signs you need it
Energy bills rising year over year, or old insulation that no longer meets R-38 for the Decatur climate zone.
What it costs in Decatur
Full removal and replacement with blown-in cellulose or fiberglass in Decatur usually runs $3,000 to $8,000 for a standard attic.
How we do it
After removal and air sealing, we install new insulation to code depth and verify final R-value with photos.
What Insulation Removal & Replacement Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Attic insulation removal | $1.50 – $3.00 / sq ft |
| Vermiculite removal | $4.00 – $8.00 / sq ft |
| Full removal + replacement | $3,000 – $8,000 |
| Contaminated insulation removal | $2,000 – $5,000 |
How do I know if my Decatur attic has vermiculite?
Vermiculite looks like small gray or brown pebbles mixed into the insulation. If you see it in a pre-1970 Decatur home, don’t disturb it. We can sample and test before any work starts. Call (855) 657-3403 to schedule an inspection.
Is it cheaper to remove old attic insulation or just add more on top?
It depends on condition. If the old material is dry, uncontaminated, and not compressed, we often blow new insulation over it. If it’s rodent-damaged, moldy, or vermiculite, removal is the only safe option. Estimates are free.
Attic Air Sealing in Decatur
Attic air sealing in Decatur stops the stack effect that pulls conditioned air out of your living space and draws hot, humid outside air into the attic. In a 1920s Oakhurst bungalow, the gaps around top plates, can lights, and the attic hatch can add up to a window left wide open all year. Sealing those leaks before adding insulation is what makes the insulation actually work. That’s the order we always follow. More on the Attic Air Sealing service.
Attic Floor Air Sealing
Signs you need it
Dust streaks on insulation, rooms that feel drafty when the HVAC runs, or unusually high winter heating bills.
What it costs in Decatur
Whole-attic floor air sealing in Decatur typically costs $1,200 to $3,000 depending on attic size and number of penetrations.
How we do it
We move aside existing insulation, seal every crack and gap with foam or caulk, then restore insulation to proper depth.
Top Plate & Penetration Sealing
Signs you need it
Visible gaps where walls meet the attic floor, or wiring and plumbing penetrations with air movement around them.
What it costs in Decatur
Top plate and penetration sealing in Decatur usually costs $800 to $2,000 for the typical bungalow attic.
How we do it
We seal along every top plate and around every pipe, wire, and duct with expanding foam or fire-rated caulk.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights that leak air into the attic, or register boots that pull attic air into the duct system.
What it costs in Decatur
Sealing can lights and duct boots in a Decatur attic typically runs $500 to $1,500 per attic.
How we do it
We install rated covers over can lights and seal every duct boot joint with mastic and mechanical fasteners.
What Attic Air Sealing Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Full attic floor air sealing | $1,200 – $3,000 |
| Top plate & penetration sealing | $800 – $2,000 |
| Can light & duct boot sealing | $500 – $1,500 |
| Attic hatch sealing | $200 – $800 |
Why do I need air sealing if I already have insulation in my Decatur attic?
Insulation slows heat transfer but does not stop air movement. In Decatur, humid air moving through gaps condenses inside the insulation, lowering its effective R-value and causing mold. Sealing first protects the insulation investment. Call (855) 657-3403.
Can air sealing really reduce my Decatur energy bill that much?
Yes, in older Decatur homes with significant leakage, air sealing plus proper insulation commonly cuts heating and cooling costs by 15 to 25 percent. The more penetrations in the ceiling plane, the bigger the gain. Estimates are free.
Wall Insulation in Decatur
Wall insulation in Decatur is retrofit work in mostly finished, occupied homes, which is why injection and drill-and-fill methods dominate. The pre-war bungalows in 2nd Avenue and Winnona Park often have literal empty wall cavities between the studs, with nothing but plaster and siding between the room and Georgia summer. Filling those cavities changes comfort more than almost any other single job. See the full Wall Insulation service.
Injection Foam Wall Insulation
Signs you need it
Exterior walls that feel cold in winter and hot in summer, or rooms that never match the thermostat setting.
What it costs in Decatur
Injection foam wall insulation in Decatur typically costs $3,500 to $9,000 for a full bungalow depending on wall area.
How we do it
We inject slow-rise foam through small holes into empty wall cavities, where it expands to fill gaps and air seal.
Drill & Fill Wall Insulation
Signs you need it
Uneven room temperatures, high humidity in summer, or hearing outside noise through exterior walls.
What it costs in Decatur
Drill and fill dense-pack cellulose in Decatur walls usually runs $3,000 to $7,000 per house.
How we do it
We drill through siding or drywall, dense-pack cellulose into each stud bay, then patch each hole to match.
Interior Wall Soundproofing
Signs you need it
Conversation, footsteps, or plumbing noise carrying between rooms in a Decatur bungalow or ranch.
What it costs in Decatur
Interior soundproofing in Decatur typically costs $1,500 to $4,000 per wall or ceiling depending on square footage.
How we do it
We install sound-absorbing insulation inside interior wall and ceiling cavities, which also gives modest thermal benefit.
What Wall Insulation Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Injection foam walls | $3,500 – $9,000 |
| Drill & fill dense-pack | $3,000 – $7,000 |
| Interior soundproofing | $1,500 – $4,000 |
| Exterior wall insulation | $5,000 – $12,000 |
Will wall insulation help with my Decatur home’s humidity problems?
Yes, empty wall cavities in a mixed-humid climate allow moisture to condense on the back side of wallboard. Filling and air sealing the cavity stops that condensation pathway and reduces indoor humidity swings. Call (855) 657-3403 for a wall assessment.
Can you insulate walls without tearing out my Decatur plaster?
Yes, drill-and-fill and injection foam methods work from the exterior or through small interior holes, preserving original plaster and trim. We patch every hole cleanly and the existing wall finish stays intact. Estimates are free.
Attic Cleaning & Rodent Proofing in Decatur
Attic cleaning and rodent proofing in Decatur deals with what the city’s dense tree canopy and older housing stock create together: squirrels, rats, and raccoons using overhanging limbs to access attics and crawl spaces. Once inside, they soil insulation, chew wiring, and leave behind contaminants that compromise air quality. Cleaning and sealing the entry points is the only durable fix. Explore the full Attic Cleaning & Rodent Proofing service.
Attic Cleanout
Signs you need it
Droppings, nesting material, or scattered insulation from animal activity, plus a strong animal smell in the attic.
What it costs in Decatur
Attic cleanout in Decatur typically costs $800 to $2,500 depending on attic size and amount of contamination.
How we do it
We remove all contaminated insulation, bag and dispose of it, and vacuum every surface clean before any new insulation goes in.
Attic Sanitizing & Decontamination
Signs you need it
Persistent odor after rodents are gone, urine stains on sheathing, or family members with unexplained allergy symptoms.
What it costs in Decatur
Attic sanitizing and decontamination in Decatur usually runs $500 to $1,500 after the cleanout is complete.
How we do it
We apply an enzyme-based antimicrobial treatment that breaks down organic waste and neutralizes odor, then fog the space.
Rodent Proofing & Exclusion
Signs you need it
Scratching in walls or ceiling at night, chew marks on fascia, or repeated infestations after previous trapping.
What it costs in Decatur
Comprehensive rodent proofing and exclusion in Decatur typically costs $1,000 to $3,500 depending on entry points and material.
How we do it
We seal every entry point with steel mesh and flashing, trim back roof access points, and reinforce vulnerable vents.
What Attic Cleaning & Rodent Proofing Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Attic cleanout | $800 – $2,500 |
| Sanitizing & decontamination | $500 – $1,500 |
| Rodent proofing & exclusion | $1,000 – $3,500 |
| Attic restoration | $1,500 – $4,000 |
Do I need to clean my Decatur attic before adding insulation?
Yes, if there’s any rodent activity or contamination. Installing new insulation over droppings and soiled material seals the problem in and continues spreading allergens through your home. Clean first, then insulate. Call (855) 657-3403.
How do rodents get into Decatur attics?
Almost always through roof gaps, soffit openings, and overhanging tree branches that touch the roof line. Decatur’s heavy canopy gives squirrels direct highways onto roofs in neighborhoods like Oakhurst. We seal every opening with steel reinforcement. Estimates are free.
Home Energy Audit in Decatur
A home energy audit in Decatur tells you exactly where your older house is losing conditioned air and what to fix first, so you stop guessing and stop paying for upgrades that don’t matter. The mixed-humid climate means both air leakage and insulation levels matter, and the audit measures both with real equipment. It’s the diagnostic starting point that makes every other insulation service smarter and more targeted. See the full Home Energy Audit service.
Blower Door Test
Signs you need it
Drafty rooms, high bills despite a newer HVAC system, or wanting a concrete number on your home’s air leakage rate.
What it costs in Decatur
A blower door test as part of a full Decatur home energy audit typically costs $300 to $600 when bundled.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure exactly how many air changes occur per hour.
Thermal Imaging Inspection
Signs you need it
Cold or hot spots on walls and ceilings you can feel but can’t explain, or suspect missing insulation in a finished wall.
What it costs in Decatur
Thermal imaging inspection in Decatur is included in our full energy audit, which runs $400 to $800 total.
How we do it
We scan every wall, ceiling, and floor with an infrared camera to visualize missing insulation and air leaks in real time.
Duct Leakage Test
Signs you need it
Some rooms never reach the thermostat setpoint, or utility bills stay high even after attic insulation improvements.
What it costs in Decatur
Duct leakage testing in Decatur typically costs $200 to $500 as part of a full diagnostic package.
How we do it
We pressurize the duct system and measure leakage to the outside, locating specific joints and boots that need sealing.
What Home Energy Audit Costs in Decatur
| Item | Typical range in Decatur |
|---|---|
| Full home energy audit | $400 – $800 |
| Blower door test | $300 – $600 |
| Thermal imaging inspection | Included with audit |
| Duct leakage test | $200 – $500 |
Is a home energy audit worth it for an older Decatur house?
Yes, especially for pre-1980 homes where air leakage and insulation gaps are unevenly distributed. The audit shows you exactly where the biggest losses are, so you spend money where it returns the most. Call (855) 657-3403 to schedule one.
How long does a home energy audit take in Decatur?
Most Decatur audits take two to four hours depending on house size and number of rooms. You get a written report with prioritized recommendations and the measured leakage numbers. Estimates are free.

FAQs About Insulation in Decatur, GA
How quickly can you schedule insulation work here?
We typically schedule an inspection within a few business days of your call, and most attic, crawl space, or wall jobs start within one to two weeks once we’ve confirmed the scope. Urgent issues, like an exposed attic or a failed vapor barrier, get priority scheduling.
Do I need a permit for insulation work in Decatur?
Decatur sits in ASHRAE Climate Zone 3A, a mixed-humid zone where code calls for meaningful attic R-value on both ends of the year. Most standard insulation and air sealing jobs don’t require a separate permit, but we target current code minimums and take care of any paperwork a project needs.
How does the written estimate process work?
We walk the attic, crawl space, or walls in person, measure the square footage, and note what condition the existing insulation is in. You get a written estimate with the recommended materials, R-values, and total price before any work begins, so there are no surprises once the crew arrives.
Which nearby areas do you cover?
We also regularly work in Houston, Spring, The Woodlands, Katy, Pearland, and Humble. If you’re just outside one of those areas, reach out and we’ll confirm whether your address falls within our current service radius.
What happens to my old insulation?
We remove and bag the old material, whether it’s compressed fiberglass, vermiculite, or insulation damaged by rodents, before installing anything new. Contaminated insulation gets disposed of according to local rules, and we sanitize the space so the new material goes into a clean attic or crawl space.

What Decatur 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."
- Marcus Hale
