Insulation in Kennesaw, GA
Effective insulation in Kennesaw starts with understanding one thing: most homes here were built between 1988 and 2008, and their original insulation was never enough for a climate where attics hit 140°F in July. A poorly sealed and under-insulated attic or crawl space quietly costs Kennesaw homeowners hundreds of dollars a year in wasted energy. We fix that with crawl space encapsulation, attic air sealing, spray foam, and blown-in insulation that matches how these specific houses actually behave.

Why Kennesaw Homes Are Different
Kennesaw’s residential building boom along the Barrett Parkway corridor and around Town Center at Cobb produced thousands of two-story subdivision homes that are now 20 to 30 years old. That age matters. Original code-minimum attic insulation has settled, and air sealing was rarely done properly at the time of construction. What makes Kennesaw unique compared with older cities like Marietta is how concentrated this housing stock is: block after block of the same builder-grade era, with the same weaknesses.
Those houses share signature construction details. Vaulted ceilings, cathedral sections, and bonus rooms over garages create fragmented attic planes that were routinely under-insulated from day one. In neighborhoods like Legacy Park, the bonus room over the garage is the single most complained-about space in the house: the garage ceiling usually has no thermal break, and the knee walls are almost never insulated. The result is a room that runs 10 to 15 degrees hotter than the rest of the house every summer. Kennesaw also sits in IECC Climate Zone 3A, a mixed-humid zone where crawl spaces hold moisture that migrates upward through the house. Crawl space encapsulation is not optional here; it is the companion fix that keeps attic work from being undermined by damp, mold-prone air rising from below.
Our Main Kennesaw Services
Two services dominate the calls we get from Kennesaw homeowners, and both trace back to that 1990s and 2000s building era: attic insulation that has settled and air sealing that was never done right in the first place.
Attic Insulation in Kennesaw
Most Kennesaw attics we inspect have R-19 or less of settled fiberglass, far short of what Zone 3A demands. We bring attic insulation up to a true R-38 or better with blown-in cellulose or fiberglass, and we handle the air sealing that makes the insulation actually work. Vaulted ceilings and bonus room knee walls are routine here. Read more about Attic Insulation in Kennesaw, including what a retrofit costs and how we handle those uneven attic planes.

Crawl Space Encapsulation & Vapor Barrier in Kennesaw
In Kennesaw’s mixed-humid climate, an unencapsulated crawl space is a slow-moving problem that gets worse every summer. Moisture rises from the dirt floor, meets warm humid air, and condenses on floor joists, ducts, and subflooring. That is how you get mold, musty odors, sagging insulation, and higher cooling bills all at once. Encapsulating the crawl space in Kennesaw means sealing the floor and walls with a reinforced vapor barrier, closing off foundation vents, and controlling moisture at the source. We install complete Crawl Space Encapsulation & Vapor Barrier systems that stop that moisture cycle permanently.
Crawl Space Vapor Barrier
Signs you need it
You smell damp earth or mildew when the AC kicks on, or you see condensation on ductwork and floor joists under the house.
What it costs in Kennesaw
A reinforced vapor barrier in a typical Kennesaw crawl space runs from $1,200 to $3,000 depending on square footage and access.
How we do it
We clean the floor, lay a 10-mil or thicker reinforced liner across the ground, run it up the walls, and mechanically fasten it at the top edge.
Crawl Space Encapsulation
Signs you need it
Humidity in the crawl space stays above 60% even after venting, or you see standing water, mold, or crumbling insulation.
What it costs in Kennesaw
Full encapsulation in Kennesaw, including sealing vents and adding a dehumidifier, typically falls between $6,000 and $15,000.
How we do it
We install the vapor barrier, seal foundation vents, insulate the walls, and add a commercial dehumidifier sized for the space.
Crawl Space Insulation
Signs you need it
Floors above the crawl space feel cold in winter, and old fiberglass batts are sagging or falling away from the joists.
What it costs in Kennesaw
Crawl space wall insulation in Kennesaw runs from $1,000 to $3,500 when done as part of an encapsulation package.
How we do it
We remove failed batts and install rigid foam or closed-cell spray foam on the crawl space walls, keeping the floor framing uninsulated so it stays dry.
What Crawl Space Encapsulation & Vapor Barrier Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Vapor barrier only | $1,200 - $3,000 |
| Crawl space wall insulation | $1,000 - $3,500 |
| Full encapsulation with dehumidifier | $6,000 - $15,000 |
| Standing water removal and grading prep | $500 - $1,500 |
Is crawl space encapsulation a good investment in Kennesaw’s climate?
Yes. Kennesaw’s mixed-humid climate means crawl space moisture is active most of the year, not just in summer. A sealed crawl space reduces cooling loads, protects floor framing from rot, and improves indoor air quality on the first floor.
Will closing crawl space vents make my house too humid in Kennesaw summers?
No. Closed vents are the point: open vents let humid outside air in, and that air condenses on cool surfaces. A proper encapsulation package includes a dehumidifier that controls moisture mechanically, which is far more reliable than venting in Zone 3A.
Spray Foam Insulation in Kennesaw
Kennesaw’s attic temperatures in July and August routinely reach 140 to 150 degrees, and that heat pushes straight down through the ceiling if your attic is under-insulated. Open-cell and closed-cell spray foam solve the problem differently than batt or blown-in insulation: they air seal and insulate in one step. That matters most in the bonus rooms, vaulted ceilings, and fragmented attic planes that define this city’s housing stock. We install Spray Foam Insulation from Demilec and Icynene, two of the most trusted names in the industry.
Open-Cell Spray Foam
Signs you need it
Your upstairs rooms are 8 to 10 degrees hotter than downstairs, and you want an air seal plus insulation in one application.
What it costs in Kennesaw
Open-cell spray foam for a Kennesaw attic typically runs $1.50 to $3.00 per board foot installed.
How we do it
We spray a continuous layer on the underside of the roof deck, covering gaps and bypasses that let hot attic air into the home.
Closed-Cell Spray Foam
Signs you need it
You need an insulation that also acts as a moisture barrier, or you have limited depth in a wall or roofline cavity.
What it costs in Kennesaw
Closed-cell spray foam in Kennesaw runs from $2.50 to $5.00 per board foot depending on depth and access.
How we do it
We spray a dense, rigid foam that insulates, air seals, and resists moisture in a single layer, ideal for rim joists and crawl space walls.
Rim Joist Spray Foam
Signs you need it
You feel drafts near exterior walls on the first floor, or your crawl space or basement rim joist shows gaps and old fiberglass stuffed loosely in cavities.
What it costs in Kennesaw
Rim joist spray foam in a typical Kennesaw home costs $800 to $2,500 for the full perimeter.
How we do it
We remove failed material and spray closed-cell foam into each rim joist cavity, sealing the gap where the foundation meets the framing.
What Spray Foam Insulation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Open-cell attic roof deck | $1.50 - $3.00 per board foot |
| Closed-cell roof deck or walls | $2.50 - $5.00 per board foot |
| Rim joist sealing (full perimeter) | $800 - $2,500 |
| Bonus room knee wall foam | $600 - $1,800 |
Is spray foam safe in a Kennesaw attic that gets over 140°F?
Yes. Spray foam is designed for exactly those conditions. Once cured, open-cell and closed-cell foam are inert and stable across the full temperature range a Kennesaw attic sees in July and August.
Which spray foam should I use for a bonus room over the garage in Kennesaw?
Usually closed-cell foam on the garage ceiling and knee walls. The garage ceiling has no thermal break, and closed-cell foam gives you the highest R-value per inch while blocking moisture and air movement at the same time.
Blown-In Insulation in Kennesaw
The fastest, most cost-effective retrofit for a Kennesaw attic is blown-in insulation. Loose-fill cellulose or fiberglass settles around irregular framing, fills the odd cavities created by vaulted ceilings, and raises R-value far faster than removing and replacing batts. For Kent’s aging two-story stock, blown-in attic insulation plus air sealing is the single highest-return energy job most homeowners can do. We use GreenFiber cellulose and Owens Corning fiberglass on Blown-In Insulation jobs here.
Blown-In Cellulose
Signs you need it
Your attic has less than R-30 of existing insulation, and you want a high-coverage material that blocks air movement better than fiberglass.
What it costs in Kennesaw
Blown-in cellulose for a typical 1,500-square-foot Kennesaw attic runs $1.20 to $2.50 per square foot installed.
How we do it
We air seal first, then blow cellulose to a consistent R-38 or R-49 depth across the entire attic floor, including hard-to-reach corners.
Blown-In Fiberglass
Signs you need it
You want a fast, inexpensive top-up over existing batts, and you prefer a material that will never settle below its rated depth.
What it costs in Kennesaw
Blown-in fiberglass in Kennesaw runs $1.00 to $2.00 per square foot for a typical attic top-up.
How we do it
We calculate the settled depth needed for R-38 or R-49, mark the depth, and blow Owens Corning fiberglass to an even, consistent layer.
Dense-Pack Wall Insulation
Signs you need it
Your exterior walls are uninsulated or have settled batts, and you want an insulation that fills the cavity completely without opening the walls.
What it costs in Kennesaw
Dense-pack wall insulation in Kennesaw runs from $2.00 to $4.50 per square foot of wall area.
How we do it
We drill small access holes, blow cellulose or fiberglass under pressure until the cavity is completely filled, and patch the holes cleanly.
What Blown-In Insulation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Cellulose attic insulation (R-38 to R-49) | $1.20 - $2.50 per sq ft |
| Fiberglass attic top-up | $1.00 - $2.00 per sq ft |
| Dense-pack wall insulation | $2.00 - $4.50 per sq ft |
| Air sealing add-on | $400 - $1,200 |
How deep should blown-in insulation be in a Kennesaw attic?
For fiberglass, roughly 14 to 17 inches for R-49. For cellulose, about 12 to 14 inches. Most Kennesaw attics we inspect have only 6 to 9 inches, which is why upstairs rooms feel so hot in summer.
Will blown-in insulation settle and lose R-value in Kennesaw’s heat?
Cellulose settles slightly, but we calculate the settled depth into the initial install so the R-value holds. Fiberglass blown to the correct depth will not settle. Heat does not reduce either material’s performance.
Radiant Barrier Installation in Kennesaw
Kennesaw attics absorb enormous radiant heat in summer, with roof deck temperatures climbing well past 130°F on a typical July afternoon. A radiant barrier reflects that heat before it reaches the attic floor and the insulation below it, reducing the heat your AC has to fight. We install Radiant Barrier Installation systems in attics across Kennesaw, often paired with blown-in insulation and air sealing for a complete summer-cooling package.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot even with the AC running, and your attic feels like an oven when you open the hatch.
What it costs in Kennesaw
A radiant barrier across a standard Kennesaw attic runs $800 to $2,000 installed.
How we do it
We staple a reinforced foil barrier to the underside of the roof rafters, leaving an air gap so the foil can reflect heat back toward the roof deck.
Radiant Barrier Foil
Signs you need it
You want the reflectivity benefit of a radiant barrier and you plan to add attic insulation later, so a standalone foil installation makes sense now.
What it costs in Kennesaw
Standalone radiant barrier foil in Kennesaw costs $0.50 to $1.50 per square foot of attic footprint.
How we do it
We measure the roof plane, pre-cut the foil, and attach it in continuous strips across the rafters to minimize gaps and maximize reflection.
Radiant Barrier Roof Deck
Signs you need it
Your roof is being replaced and you want the radiant barrier installed from the outside while the deck is exposed.
What it costs in Kennesaw
Radiant barrier roof deck installation during a re-roof runs $1,000 to $2,500 depending on roof size.
How we do it
We coordinate with the roofing contractor to apply a radiant barrier sheet to the roof deck before shingles go down, reflecting heat at the source.
What Radiant Barrier Installation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Attic radiant barrier (installed) | $800 - $2,000 |
| Standalone foil | $0.50 - $1.50 per sq ft |
| Roof deck radiant barrier | $1,000 - $2,500 |
How much can a radiant barrier reduce my cooling bill in Kennesaw?
A radiant barrier typically cuts ceiling heat gain by 15 to 25% in a Kennesaw summer, which translates to lower cooling costs. The exact savings depend on attic size, existing insulation, and how much time the AC runs.
Does a radiant barrier work in Kennesaw winters?
It has minimal effect on winter heating. Radiant barriers mainly address summer heat gain, which is Kennesaw’s dominant energy problem. They do not interfere with insulation’s ability to slow heat loss in winter.
Insulation Removal & Replacement in Kennesaw
After 20 to 30 years of Kennesaw summers and the humidity that comes with them, attic insulation can be compacted, contaminated, or simply ineffective. Removal becomes necessary when old insulation has been saturated from roof leaks, contaminated by rodents, or when it contains materials that should not stay in place. We provide Insulation Removal & Replacement across Kennesaw, removing failed material down to the deck and rebuilding the insulation system properly.
Attic Insulation Removal
Signs you need it
Your attic insulation is compressed, dusty, or underperforming, and you want a clean slate before adding new material.
What it costs in Kennesaw
Attic insulation removal in Kennesaw runs $1.00 to $2.50 per square foot depending on depth and access.
How we do it
We use a commercial vacuum system to extract old insulation down to the attic deck, then haul it away for disposal.
Contaminated Insulation Removal
Signs you need it
You see rodent droppings, staining, or smell urine in the attic, and the insulation is no longer safe to leave in place.
What it costs in Kennesaw
Contaminated insulation removal in Kennesaw costs $2.00 to $4.00 per square foot, including sanitation prep.
How we do it
We remove all contaminated material under containment, then sanitize the affected surfaces before any new insulation goes in.
Vermiculite & Old Insulation Removal
Signs you need it
Your attic contains loose vermiculite or outdated insulation, and you want it removed before it becomes a liability.
What it costs in Kennesaw
Vermiculite removal in Kennesaw starts at $4.00 per square foot due to specialized handling requirements.
How we do it
We follow strict containment and disposal protocols for vermiculite, treating it as potentially asbestos-containing material until proven otherwise.
What Insulation Removal & Replacement Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Standard attic removal | $1.00 - $2.50 per sq ft |
| Contaminated removal & sanitizing | $2.00 - $4.00 per sq ft |
| Vermiculite removal | $4.00+ per sq ft |
| Replacement blown-in insulation | $1.20 - $2.50 per sq ft |
Is it cheaper to remove and replace insulation or add more on top in Kennesaw?
Adding more is cheaper initially, but layering over wet, compacted, or contaminated insulation preserves the problem. Removal and replacement is the only option when old material is compromised, and it lets us air seal the attic floor at the same time.
How long does attic insulation removal take in a Kennesaw home?
Most standard attic removals are completed in one day. Larger homes or those with contaminated material may take longer. The work is done under containment so dust does not spread through the house.
Attic Air Sealing in Kennesaw
Air sealing is the step most Kennesaw attics never got when they were built. Gaps around top plates, wiring penetrations, can lights, and duct boots let conditioned air leak straight out of the living space into a 140°F attic. That is why two identical Kennesaw homes can have very different energy bills. We perform Attic Air Sealing before adding insulation, because sealing after insulating means pulling the insulation back out.
Attic Floor Air Sealing
Signs you need it
You feel drafts upstairs, or your energy bills spike in July and January even though the thermostat stays set.
What it costs in Kennesaw
Whole-attic floor air sealing in Kennesaw runs $600 to $1,800 depending on attic size and number of penetrations.
How we do it
We clear insulation from key areas, seal every gap and crack with foam or caulk, and then replace and top up the insulation.
Top Plate & Penetration Sealing
Signs you need it
You can see light coming through gaps where interior walls meet the attic floor, or around plumbing and wiring penetrations.
What it costs in Kennesaw
Top plate and penetration sealing in Kennesaw costs $300 to $800 as part of a larger air sealing package.
How we do it
We seal every top plate seam, electrical penetration, and plumbing vent with fire-rated foam or caulk matched to the gap size.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights are hot to the touch, or you feel air leaking around the duct boots where they meet the ceiling.
What it costs in Kennesaw
Can light and duct boot sealing in Kennesaw typically runs $200 to $600, depending on the number of fixtures and registers.
How we do it
We install sealed covers over recessed lights rated for insulation contact and seal every duct boot to the drywall with mastic and foam.
What Attic Air Sealing Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Whole-attic floor air sealing | $600 - $1,800 |
| Top plate and penetration sealing | $300 - $800 |
| Can light and duct boot sealing | $200 - $600 |
| Attic hatch sealing and insulation | $150 - $350 |
Can I add insulation without air sealing my Kennesaw attic?
You can, but it won’t work well. Insulation slows heat transfer but does not stop air movement. In a Kennesaw attic that reaches 140°F, air leaks carry heat and humidity straight into the house, bypassing the insulation entirely.
How much does air sealing save on a Kennesaw energy bill?
Air sealing alone typically cuts heating and cooling costs by 10 to 15% in a Kennesaw home. Combined with insulation to R-49, the savings often reach 20 to 30% annually. The fastest way to know is a blower door test.
Wall Insulation in Kennesaw
Kennesaw homes built before about 1990 often have inadequate wall insulation, and even newer homes suffer in specific places: bonus room knee walls, garage-adjacent walls, and the cavities around vaulted ceilings. Wall insulation is more invasive than attic work, but the comfort payoff is immediate, especially in rooms that have never held temperature well. We install Wall Insulation using injection foam and drill-and-fill methods that avoid tearing out drywall.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel cold in winter and warm in summer, and you want insulation added without removing drywall.
What it costs in Kennesaw
Injection foam wall insulation in Kennesaw runs $2.50 to $5.00 per square foot of wall area.
How we do it
We drill small holes in each stud cavity and inject slow-rise foam that fills the entire cavity without sagging or settling.
Drill & Fill Wall Insulation
Signs you need it
You have open wall cavities or old batts that have slumped, and you want a dense-packed material that blocks air movement.
What it costs in Kennesaw
Drill-and-fill wall insulation in Kennesaw costs $2.00 to $4.50 per square foot.
How we do it
We access each stud bay through small openings and dense-pack cellulose or fiberglass until the cavity is completely full and airtight.
Interior Wall Soundproofing
Signs you need it
You hear conversations, TVs, or plumbing noise through interior walls, and you want a quieter home.
What it costs in Kennesaw
Interior wall soundproofing in Kennesaw runs $1.50 to $3.50 per square foot depending on the material chosen.
How we do it
We install acoustic batts or blown-in material in interior wall cavities, focusing on bedrooms, bathrooms, and home offices.
What Wall Insulation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Injection foam wall insulation | $2.50 - $5.00 per sq ft |
| Drill-and-fill wall insulation | $2.00 - $4.50 per sq ft |
| Interior wall soundproofing | $1.50 - $3.50 per sq ft |
| Bonus room knee wall insulation | $600 - $1,800 |
Can you insulate the walls of a bonus room over the garage in Kennesaw without tearing out drywall?
Yes. The knee walls and garage ceiling can almost always be insulated from the attic or garage side without disturbing finished surfaces. This is one of the highest-impact improvements for that specific Kennesaw floor plan.
How do I know if my Kennesaw walls are insulated?
Remove an outlet cover on an exterior wall and look past the electrical box. If you see empty cavity space, the wall is likely uninsulated. A thermal imaging inspection during a home energy audit confirms it across the whole house.
Attic Cleaning & Rodent Proofing in Kennesaw
Kennesaw’s mix of mature trees, subdivision lot lines, and older roof designs creates ideal entry conditions for squirrels, rats, and mice. Once rodents get into an attic, they contaminate insulation, chew wiring, and leave behind waste that becomes an air quality problem. We provide Attic Cleaning & Rodent Proofing that removes the contaminated material, sanitizes the space, and seals the entry points so the problem does not return.
Attic Cleanout
Signs you need it
You hear scratching or scurrying overhead at night, or you see droppings and nesting material in the attic.
What it costs in Kennesaw
An attic cleanout in Kennesaw runs $800 to $2,500 depending on attic size and volume of debris.
How we do it
We remove contaminated insulation and debris under containment, then vacuum and prepare the space for sanitizing and new insulation.
Rodent Proofing & Exclusion
Signs you need it
You have active rodent activity, or you want to prevent future entry after a cleanout.
What it costs in Kennesaw
Rodent proofing and exclusion in Kennesaw costs $600 to $2,000 depending on the number and location of entry points.
How we do it
We seal roof returns, gable vents, soffit gaps, and any opening larger than a quarter inch with metal mesh and pest-resistant materials.
Attic Sanitizing & Decontamination
Signs you need it
Your attic smells strongly of urine or there is visible staining and waste, even after rodents are gone.
What it costs in Kennesaw
Attic sanitizing in Kennesaw runs $500 to $1,500 as part of a full cleanout or as a standalone treatment.
How we do it
We apply an enzyme-based treatment to break down waste and odors, then follow with a sanitizing fog across the affected surfaces.
What Attic Cleaning & Rodent Proofing Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Attic cleanout | $800 - $2,500 |
| Rodent proofing & exclusion | $600 - $2,000 |
| Attic sanitizing & decontamination | $500 - $1,500 |
| New insulation after cleanout | $1.20 - $2.50 per sq ft |
How do rodents get into Kennesaw attics?
Most enter through roof returns, gable end vents, uncapped chimneys, or gaps where siding meets the roofline. Kennesaw’s older subdivisions have mature trees close to rooflines, which gives squirrels direct access to the roof.
Should I replace insulation after rodent removal in my Kennesaw attic?
Yes, in most cases. Rodent urine and droppings contaminate insulation and create ongoing odor and air quality problems. Compromised insulation should be removed and replaced, not covered over.

Home Energy Audit in Kennesaw
A home energy audit is the logical starting point for almost every Kennesaw home, because it tells you exactly where your house is losing energy before you spend a dollar on insulation. Most audits here show the same pattern: significant air leakage at the top of the house, settled attic insulation, and bonus rooms that act as thermal weak points. We perform Home Energy Audit testing with blower door equipment and thermal imaging to pin down the problems precisely.
Blower Door Test
Signs you need it
Your home feels drafty, your bills are high, and you want a single measurement of how much air your house leaks.
What it costs in Kennesaw
A blower door test in Kennesaw typically costs $200 to $500 as part of a full audit or as a standalone test.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure total air leakage in cubic feet per minute.
Thermal Imaging Inspection
Signs you need it
Certain rooms are always hot or cold, and you want to see exactly where the insulation is missing without opening walls.
What it costs in Kennesaw
Thermal imaging in Kennesaw runs $150 to $400 when combined with a blower door test and audit.
How we do it
We scan walls, ceilings, and floors with an infrared camera to locate missing insulation, air leaks, and thermal bridging in real time.
Insulation Inspection
Signs you need it
You suspect your attic insulation is underperforming or has settled, and you want an expert assessment before spending on repairs.
What it costs in Kennesaw
A standalone insulation inspection in Kennesaw runs $100 to $300.
How we do it
We measure insulation depth, document gaps and compression, and compare your current R-value against what Zone 3A requires.
What Home Energy Audit Costs in Kennesaw

FAQs About Insulation in Kennesaw, GA
How quickly can you schedule a Kennesaw job?
We typically schedule Kennesaw visits within a few days of your call, sooner if the bonus room over your garage has never been properly insulated and it is affecting comfort. If your timing is flexible we’re happy to work around it, and either way we’ll confirm the exact appointment window with you before the day of the visit.
Is a permit needed for insulation work in Kennesaw?
Routine attic and wall insulation generally does not require a separate permit in Kennesaw. Larger jobs involving structural changes sometimes do, and we handle that paperwork as part of the project.
How does the estimate process work?
We inspect the attic, including fragmented sections around vaulted ceilings and bonus rooms, and give you a specific written price before starting any work. That estimate spells out materials, labor, and any disposal costs, and the number does not change once the crew arrives unless you ask us to add more scope to the job.
What areas near Kennesaw do you cover?
Along with Kennesaw, we serve Houston, Spring, The Woodlands, Katy, Pearland, and Humble. Contact us with your address to confirm. If you’re not sure whether your address falls inside that range, just tell us your city and zip when you call and we’ll confirm coverage right away.
What happens to the old insulation you remove?
Old insulation is bagged and hauled away as part of the job. Knee wall and bonus-room cavities get checked carefully since they are often under-insulated from the original build. We keep the work area clean throughout the job and walk you through the finished space before we leave.

What Kennesaw Customers Say
"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"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
