Insulation in Kennesaw, GA
Crawl space encapsulation and vapor barrier work in Kennesaw usually costs between $5,500 and $12,000 depending on square footage, access, and how much moisture control the space needs. Most homes here sit on vented crawl spaces or slabs, and with Georgia’s mixed-humid climate, groundwater vapor rises into floor framing nearly year-round. If your floors feel damp, your HVAC struggles, or you smell musty air inside your home, call Walt’s Insulation at (866) 751-4428 for a free estimate from a local crew that answers the phone live, 24/7.
Why Kennesaw Homes Are Different
Kennesaw’s residential stock exploded between 1980 and 2000, and the subdivisions along Wade Green Road and Jiles Road NW share a remarkably uniform set of insulation problems. Builders put HVAC air handlers and ductwork in vented attics, then insulated only the attic floor to R-19 or R-30. Georgia’s energy code now targets R-49 for attics, which means thousands of tract homes in Kennesaw are running at less than two-thirds of current required performance. On a summer afternoon with attic temperatures above 130°F, that under-insulated attic loads the cooling system directly, pushing cooling costs 20-30% higher than they should be.
Add in IECC Climate Zone 3A humidity, and you have a city where conditioned-attic spray foam conversions are a genuinely defining upgrade. The same heat and moisture also work against vented crawl spaces under homes off Barrett Parkway and Cherokee Street NW. Mild, damp winters create condensation on ductwork and floor joists, and by spring, that moisture has become the musty air you smell in the hallway. Kennesaw homes were built to minimum code for their era, and now they need correction, not just another bag of fiberglass.
Our Main Kennesaw Services
Kennesaw homeowners call Walt’s Insulation about two things more than anything else: attics that need a different approach than the R-19 the builder left behind, and crawl spaces that never quite dried out. Both have their own dedicated pages with full pricing and sub-job details.
Attic Insulation in Kennesaw
Most attics in Kennesaw still hold degraded, settled fiberglass batts installed between 1980 and 2000, and the fix usually involves more than topping up. The condition of the air sealing, ductwork, and roof deck all matter before any new insulation goes in. Attic Insulation in Kennesaw covers what we see in attics across the city, the local pricing, and what to ask before anyone climbs your ladder.

Crawl Space Encapsulation & Vapor Barrier in Kennesaw
Crawl space encapsulation in Kennesaw typically runs $5,500 to $12,000, and the job matters more here than in drier parts of Georgia because of Climate Zone 3A humidity. Homes built in the 1980s and 1990s along Wade Green Road and Jiles Road NW often have vented crawl spaces where warm, moist air condenses on floor joists and ductwork. Encapsulation seals the space and controls the moisture that causes musty air, warped floors, and higher energy bills. Crawl Space Encapsulation & Vapor Barrier is work we do regularly in Kennesaw because the housing stock demands it.
Crawl Space Vapor Barrier
Signs you need it
You smell damp, earthy air in the hallway, and the floors above the crawl space feel cold or clammy in winter. There may also be visible condensation on ducts or staining on the foundation walls.
What it costs in Kennesaw
A vapor barrier for a standard crawl space in Kennesaw usually falls between $2,500 and $5,500 depending on access and square footage.
How we do it
We lay a thick polyethylene liner across the floor and run it up the walls, sealing seams and piers. Then we tape all joints and ensure the liner drains toward a sump or low point if one exists.
Crawl Space Encapsulation
Signs you need it
HVAC runs constantly in summer, floorboards feel springy, and the crawl space smells like wet earth after rain. You might also see surface mold on floor joists or wet insulation hanging from the floor above.
What it costs in Kennesaw
Full encapsulation in Kennesaw, including liner, wall insulation, and sealing, runs $5,500 to $12,000 depending on crawl space size and height.
How we do it
We seal foundation vents, install a reinforced vapor barrier, insulate the walls, and add a dehumidifier where humidity levels call for one. The result is a dry, sealed space that stops feeding moisture into your home.
Crawl Space Moisture Control
Signs you need it
You find rust on duct straps, small puddles after heavy rain, or dark staining around foundation corners. Musty air in the home usually tracks back to crawl space moisture.
What it costs in Kennesaw
Moisture control work in Kennesaw often ranges from $2,500 to $6,000 if ventilation sealing and a dehumidifier are included.
How we do it
We locate moisture entry points, close off outside air intake, and install drainage or a dehumidifier based on measured humidity. We may also replace wet, sagging insulation under the floor.
What Crawl Space Encapsulation & Vapor Barrier Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Crawl space vapor barrier (floor and wall liner) | $2,500 - $5,500 |
| Full crawl space encapsulation | $5,500 - $12,000 |
| Crawl space moisture control with dehumidifier | $2,500 - $6,000 |
| Insulation under floor, replacement | $1,800 - $3,500 |
Does a vapor barrier stop musty smells in Kennesaw homes?
Yes, in most cases. The smell comes from moisture moving up from the soil, and a sealed vapor barrier stops that transfer. Homes that continue smelling after encapsulation usually have a vented attic that is pulling air through the house.
Can you do crawl space encapsulation in a tight crawl space on Jiles Road?
Yes. Tight or shallow crawl spaces are common in Kennesaw subdivisions, and our crews work them regularly. Access hatches and low clearance add labor but do not usually rule out encapsulation.
Spray Foam Insulation in Kennesaw
Spray foam insulation in Kennesaw usually costs $1.80 to $4.50 per board foot depending on open-cell or closed-cell product, and older subdivisions here have a specific reason to use it. The 1980s and 1990s tract homes along Wade Green Road and around Jiles Road NW put HVAC equipment in vented attics, so attic heat directly loads the system. Spray Foam Insulation at the roofline converts that attic to conditioned space, and it is the single most effective fix for Kennesaw’s builder-era energy losses.
Open-Cell Spray Foam
Signs you need it
Upstairs rooms run 8-10 degrees warmer than downstairs in summer, and the HVAC runs constantly, even when the thermostat is set low.
What it costs in Kennesaw
Open-cell spray foam for attic rooflines in Kennesaw typically runs $1.80 to $3.00 per board foot applied.
How we do it
We prep the roofline, check ventilation and electrical runs, then spray a continuous air-sealing layer across the underside of the roof deck. We finish by sealing any gaps around eaves and gable ends.
Closed-Cell Spray Foam
Signs you need it
You want the highest R-value per inch, you have moisture concerns in a crawl space or rim joist, or you are insulating a small, hard-to-access cavity from inside.
What it costs in Kennesaw
Closed-cell foam in Kennesaw generally runs $3.00 to $4.50 per board foot, depending on depth and access.
How we do it
We apply the foam in controlled passes, building to the required depth, and check for voids as we go. Closed-cell also adds structural rigidity, which helps older Kennesaw framing.
Rim Joist Spray Foam
Signs you need it
Cold floors in winter, drafts at the perimeter of upstairs and main-floor rooms, and higher heating bills even with attic insulation present.
What it costs in Kennesaw
Rim joist sealing with spray foam in Kennesaw usually costs $800 to $2,200 for an average home.
How we do it
We clear debris along the rim joist, then spray a continuous foam seal around the sill plate and band joist. This closes a major air leak point that builders left open.
What Spray Foam Insulation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Open-cell spray foam (roofline) | $1.80 - $3.00 per board foot |
| Closed-cell spray foam | $3.00 - $4.50 per board foot |
| Rim joist spray foam sealing | $800 - $2,200 |
| Garage ceiling spray foam | $1,500 - $3,200 |
Will spray foam work in a 1980s vented attic in Kennesaw?
Yes. In fact, that is where we recommend it most. The key is sealing the roofline and removing the vented attic as a heat source for the ductwork. The savings show up in summer, when attic temperatures here pass 130°F.
Can you spray foam only part of the attic roof deck?
We can, but we do not recommend partial roofline spray if your HVAC equipment is up there. A partial layer still leaves thermal bypasses. Full roof deck coverage keeps the attic temperature stable and the HVAC load predictable.
Blown-In Insulation in Kennesaw
Blown-in insulation in Kennesaw usually costs $1,800 to $5,000 for an attic top-up or full removal replacement, depending on depth and square footage. The homes along Jiles Road NW and Wade Green Road often still carry builder-grade fiberglass that settled to R-19 or less, far below Georgia’s R-49 attic target. Blown-In Insulation gives us a fast, even way to correct that deficiency without tearing out drywall.
Blown-In Cellulose
Signs you need it
Attic insulation is dusty, settled, and inconsistent from one end to the other, or you can see ceiling joists above the existing layer.
What it costs in Kennesaw
Blown-in cellulose for an average Kennesaw attic typically runs $1,800 to $4,000 depending on depth and attic size.
How we do it
We air-seal the attic first, then blow cellulose to the specified depth using a calibrated machine. We level the coverage and check depth markers so the R-value is consistent across the whole attic.
Blown-In Fiberglass
Signs you need it
You want a lighter-weight insulation, or the attic floor has areas of compressed batt that cannot be saved. Blown fiberglass also works well for topping up old fiberglass.
What it costs in Kennesaw
Blown-in fiberglass in Kennesaw generally runs $1,800 to $5,000 for a full attic, with top-ups on the lower end.
How we do it
We remove or level damaged material, seal air leaks, and blow fiberglass to a consistent depth. We then verify the depth in multiple spots to confirm the R-value you were quoted.
Dense-Pack Wall Insulation
Signs you need it
Walls feel cold in winter, rooms along exterior walls run warmer in summer, and your home was built before 2000 with hollow wall cavities.
What it costs in Kennesaw
Dense-pack wall insulation in Kennesaw ranges from $2,800 to $7,500 depending on wall area and access.
How we do it
We drill small access holes through siding or drywall, then blow cellulose or fiberglass into the cavities under pressure. We fill each cavity fully, then patch and restore the surface.
What Blown-In Insulation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Blown-in attic insulation (fiberglass or cellulose) | $1,800 - $5,000 |
| Blown-in top-up over existing attic insulation | $850 - $2,400 |
| Dense-pack wall insulation | $2,800 - $7,500 |
| Attic blow-in with air sealing included | $2,500 - $6,000 |
Can you blow insulation directly over old fiberglass batts?
Yes, if the old batts are dry and compressed flat, we commonly blow fiberglass or cellulose over them. The builder batts lose R-value when settled, and a top-up returns the attic to a consistent, current level.
What R-value should a Kennesaw attic have?
Current Georgia energy code targets R-49 for attics. Most 1980s and 1990s-era homes in Kennesaw are sitting at R-19 to R-30. Closing that gap is one of the fastest utility-bill fixes available for these homes.
Radiant Barrier Installation in Kennesaw
Radiant barrier installation in Kennesaw typically costs $1,200 to $3,500 depending on attic size and roofline geometry. Summer attic temperatures in this city routinely exceed 130°F, and a radiant barrier stapled under the roof deck blocks much of that radiant heat from reaching the insulation below. Radiant Barrier Installation is especially effective in the older Kennesaw subdivisions where ductwork sits in vented attics.
Attic Radiant Barrier
Signs you need it
Your upstairs runs hot in summer even with insulation on the attic floor, and the attic itself feels unbearable within minutes of opening the hatch.
What it costs in Kennesaw
An attic radiant barrier in Kennesaw usually costs $1,200 to $3,500, with roofline area as the main price driver.
How we do it
We staple reflective foil under the roof decking, leaving air gaps where the material needs them, and we work around existing wiring and roof vents. The barrier reflects radiant heat before it enters the attic airspace.
Radiant Barrier Roof Deck
Signs you need it
The roof deck faces full western or southern exposure, and the master bedroom ceiling below stays warm long after sunset.
What it costs in Kennesaw
Roof deck radiant barrier in Kennesaw is often priced as part of the full attic, from $800 to $2,800 for a partial or full deck installation.
How we do it
We run the barrier across the underside of the roof deck, cutting around vent chutes and roof penetrations. In a vented attic, we keep the air space below the deck open so the reflection still works.
Radiant Barrier & Ventilation
Signs you need it
Your attic has a ridge vent, but summer heat still soaks through the ceiling, or the existing soffit vents are partially blocked by old insulation.
What it costs in Kennesaw
Combined radiant barrier and ventilation corrections in Kennesaw run $1,500 to $3,500, depending on how much vent work is needed.
How we do it
We check soffit and ridge vent flow first, clear blockages, then install the radiant barrier. Without airflow, the barrier alone cannot do its job in a Kennesaw summer.
What Radiant Barrier Installation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Full attic radiant barrier | $1,200 - $3,500 |
| Roof deck radiant barrier (partial or full) | $800 - $2,800 |
| Radiant barrier with ventilation correction | $1,500 - $3,500 |
| Radiant barrier over garage attic only | $600 - $1,500 |
Will a radiant barrier alone fix a hot upstairs in Kennesaw?
It helps, but it is rarely a complete fix. Radiant barriers reduce heat gain through the roof deck, but air leaks, duct leaks, and insufficient attic floor insulation also drive uncomfortable upstairs rooms. We usually combine it with air sealing or a top-up.
Does a radiant barrier work with a vented attic in Kennesaw?
Yes, a vented attic is actually the best fit for a radiant barrier. The barrier reflects heat while the vents keep the air moving, so the attic stays measurably cooler during Kennesaw’s hot afternoons.
Insulation Removal & Replacement in Kennesaw
Insulation removal and replacement in Kennesaw generally ranges from $1,500 to $5,000 for an attic, more if the material is contaminated or vermiculite is present. Older homes around Wade Green Road and Cherokee Street NW often have settled fiberglass or, in pre-1990 builds, materials we want to test before touching. Insulation Removal & Replacement is the right call when rodent activity, moisture, or years of settlement have destroyed the original R-value.
Attic Insulation Removal
Signs you need it
Insulation is matted, wet, or packed down in areas, or a roof leak has soaked the attic floor covering. Discoloration and compressed spots are common signs.
What it costs in Kennesaw
Attic insulation removal in Kennesaw typically runs $1,500 to $3,500 depending on attic size and material type.
How we do it
We use a high-powered vacuum system to remove the old material to the attic floor deck, then haul it away. We check for moisture and air leaks before any new insulation goes down.
Contaminated Insulation Removal
Signs you need it
You have visible rodent droppings, nesting material, or a history of squirrels or raccoons in the attic. Urine staining and gnawed ductwork are serious indicators.
What it costs in Kennesaw
Contaminated insulation removal in Kennesaw runs $2,000 to $5,000, with higher costs if full sanitizing and enzyme treatment are included.
How we do it
We bag and remove all contaminated material, treat the attic surfaces, and sanitize the space before installing new insulation. This is dirty, necessary work, and it requires the right protective gear.
Insulation Replacement
Signs you need it
Energy bills have climbed year over year, and the existing attic insulation measures far below R-49. Spot repairs have not solved uneven temperatures across the upstairs.
What it costs in Kennesaw
Insulation replacement in a Kennesaw attic typically runs $2,500 to $6,000 including new material and full removal.
How we do it
We remove the old insulation, air-seal the attic plane, and blow in new cellulose or fiberglass to the specified depth. The difference in comfort is immediate, especially in homes built before 2000.
What Insulation Removal & Replacement Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Attic insulation removal | $1,500 - $3,500 |
| Contaminated insulation removal with sanitizing | $2,000 - $5,000 |
| Full removal and new blown-in insulation | $2,500 - $6,000 |
| Vermiculite testing and removal | $1,800 - $4,200 |
Should I remove old insulation before adding new in Kennesaw?
Not always. If the old material is dry, solid, and uncontaminated, a top-up works. You should remove it if there is rodent waste, moisture damage, or the material has settled so unevenly that a fresh start makes sense.
How do you handle old vermiculite insulation in Kennesaw homes?
We test it before we touch it. Vermiculite was common in older attics, and some sources contained asbestos. If testing returns positive, we follow state-required handling and disposal procedures.
Attic Air Sealing in Kennesaw
Attic air sealing in Kennesaw usually costs $900 to $2,800 depending on attic size and how many penetrations need sealing. Homes built in the 1980s and 1990s here were not sealed to modern standards, and the gaps around top plates, can lights, and the attic hatch let conditioned air leak into a 130°F attic. Attic Air Sealing is the half of the insulation job most builders skipped in this city’s big growth decades.
Attic Floor Air Sealing
Signs you need it
You see dirty insulation around cracks, darkened fiberglass near gaps, or cold, dusty airflow around ceiling fixtures on the floor below.
What it costs in Kennesaw
Attic floor air sealing in Kennesaw typically runs $1,200 to $2,800, depending on the number of penetrations and the attic’s layout.
How we do it
We pull back insulation where needed, seal gaps around wire and pipe penetrations, top plates, and chase walls, then re-cover everything. The air sealing happens before any new insulation goes in.
Can Light & Duct Boot Sealing
Signs you need it
You feel air moving around ceiling can lights, or the ducts where they enter the rooms seem loose and pull attic air into the house.
What it costs in Kennesaw
Can light and duct boot sealing in Kennesaw generally runs $400 to $1,400 depending on how many fixtures and boots need work.
How we do it
We seal around recessed cans using approved covers or sealant, then close gaps where the duct boots meet the drywall. This stops attic air from being pulled into the living space.
Attic Hatch Sealing
Signs you need it
The attic hatch in your hallway feels warm or hot in summer, or you see a dust ring around it from air movement. This one opening can leak as much as a small window left open.
What it costs in Kennesaw
Attic hatch air sealing and insulated cover installation in Kennesaw typically costs $250 to $600.
How we do it
We install weatherstripping around the hatch frame, insulate the hatch panel, and add a sealed cover box. The hatch is often the single easiest air leak to fix in older Kennesaw homes.
What Attic Air Sealing Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Full attic floor air sealing | $1,200 - $2,800 |
| Can light and duct boot sealing | $400 - $1,400 |
| Attic hatch sealing and cover | $250 - $600 |
| Air sealing with blown-in top-up | $1,500 - $3,800 |
Why does air sealing matter before insulation in Kennesaw?
Because insulation slows heat transfer but does not stop air movement. In Kennesaw’s summers, air leaking into a vented attic pulls conditioned air out of the house, and insulation only covers the gaps. Sealing first makes the insulation work as designed.
Can you seal an attic without removing the old insulation?
Yes. We move insulation aside or work around it, seal the penetrations, and then re-lay the material. Most Kennesaw attic air sealing jobs do not require full insulation removal.
Wall Insulation in Kennesaw
Wall insulation in Kennesaw typically runs $2,800 to $7,500 for a full drill-and-fill or injection foam job. The tract homes built along Wade Green Road and Jiles Road NW during the 1980s and 1990s often have wall cavities with minimal or missing insulation, and homeowners feel it in every winter cold snap. Wall Insulation closes the gap between the studs and stops the wall-driven heat gain that keeps rooms facing afternoon sun uncomfortable.
Injection Foam Wall Insulation
Signs you need it
Rooms with south or west-facing exterior walls won’t hold temperature, and the interior drywall feels noticeably cold or warm compared to interior walls.
What it costs in Kennesaw
Injection foam wall insulation in Kennesaw ranges from $3,200 to $7,500 depending on wall area.
How we do it
We drill small holes through the exterior or interior surface and inject slow-rise foam that fills the cavity around existing wiring and plumbing. The foam expands and hardens, creating an air-sealing and insulating layer.
Drill & Fill Wall Insulation
Signs you need it
Your home was built with hollow wall cavities, and you want a lower-cost material like cellulose or fiberglass blown into the stud bays.
What it costs in Kennesaw
Drill and fill wall insulation in Kennesaw usually runs $2,800 to $6,500 for an average two-story home.
How we do it
We drill access holes in each stud bay, blow the material to a set density, then patch and touch up the surface. The process works from inside or outside, depending on your siding and room layout.
Interior Wall Soundproofing
Signs you need it
You can hear conversations or TV through interior walls, or bedrooms share a wall with a bathroom and plumbing noise travels.
What it costs in Kennesaw
Interior wall soundproofing in Kennesaw generally runs $1,800 to $4,500 depending on the number of shared walls.
How we do it
We fill interior wall cavities with a dense insulation product and seal around electrical boxes. This cuts sound transfer noticeably, especially in homes with open floorplans and hard-surface flooring.
What Wall Insulation Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Injection foam wall insulation | $3,200 - $7,500 |
| Drill and fill wall insulation | $2,800 - $6,500 |
| Interior wall soundproofing | $1,800 - $4,500 |
| Exterior wall cavity sealing and insulation | $2,500 - $6,000 |
Can you insulate the walls of a 1990s Kennesaw home without tearing out drywall?
Yes. Drill-and-fill and injection foam methods both work from small access holes, so the drywall or siding stays mostly intact. The patching is minor, and we match the surface afterward.
Which wall insulation works best for Georgia humidity?
Injection foam is strong here because it also air-seals, which reduces the moist air movement that causes condensation inside wall cavities. Cellulose and fiberglass both work when installed to proper density, but they do not seal as completely.
Attic Cleaning & Rodent Proofing in Kennesaw
Attic cleaning and rodent proofing in Kennesaw generally costs $600 to $2,800, though full sanitizing and re-insulation pushes the total higher. The older subdivisions around Kennesaw have mature tree cover close to rooftops, and squirrels and rats use those branches as highways into vented attics. Attic Cleaning & Rodent Proofing removes what they leave behind and closes the entry points so they cannot return.
Attic Cleanout
Signs you need it
You hear scratching in the ceiling, find droppings in stored boxes, or see nesting material scattered around the attic.
What it costs in Kennesaw
An attic cleanout in Kennesaw usually runs $600 to $1,800 depending on attic size and debris volume.
How we do it
We remove contaminated insulation, nesting, and debris, then vacuum and prep the space for restoration. Everything is bagged and removed from the property, not left in your yard.
Rodent Proofing & Exclusion
Signs you need it
You have had rodent activity before and you want the entry points sealed so it does not happen again. Chewed soffit edges and gaps at roof junctions are common signs.
What it costs in Kennesaw
Rodent proofing and exclusion in Kennesaw ranges from $500 to $2,200 depending on the number of access points and roofline complexity.
How we do it
We find every opening larger than a pencil, seal entry points with metal flashing or hardware cloth, and secure attic vents. The goal is a sealed attic where rodents cannot re-enter.
Attic Sanitizing & Decontamination
Signs you need it
Odors persist after cleaning, or staining from urine and droppings covers sheathing and framing. Health concerns are a valid reason to sanitize, too.
What it costs in Kennesaw
Attic sanitizing and decontamination in Kennesaw typically adds $800 to $2,500 to the cleanout cost.
How we do it
We treat the affected surfaces with an enzyme-based solution that breaks down waste and odor, then fog the attic space. After drying, new insulation can be installed safely.
What Attic Cleaning & Rodent Proofing Costs in Kennesaw
| Item | Typical range in Kennesaw |
|---|---|
| Attic cleanout | $600 - $1,800 |
| Rodent proofing and exclusion | $500 - $2,200 |
| Sanitizing and decontamination | $800 - $2,500 |
| Full cleanout with sanitizing and new insulation | $2,500 - $5,500 |
Do you handle the rodents themselves or just proofing?
We handle the proofing, exclusion, and cleanup work. If live animals are present, we coordinate with a licensed pest control partner to remove them first, then we seal the entry points and restore the attic.
How do rodents get into Kennesaw attics?
Mostly through roof junctions and vents. Tree limbs overhanging the roof give squirrels and rats direct access to soffits and gable ends. Once they chew a small gap, the attic becomes shelter, and the damage accelerates quickly.

FAQs About Insulation in Kennesaw, GA
How quickly can you schedule an insulation job in Kennesaw?
We typically schedule inspections within a few business days of your call, and most crawl space, attic, and wall jobs are completed within one to two visits. Exact timing depends on current job volume and the scope of work, but we will give you a start date once we have seen the space in person.
Do I need a permit for insulation work here?
Kennesaw’s 1980s and 1990s tract homes were often built to R-19 or R-30 attic standards, well under the R-49 Georgia’s Climate Zone 3A now recommends. Standard attic and crawl space insulation work typically does not require a separate permit.
How does the written estimate process work?
We inspect your attic, crawl space, or walls in person, measure square footage, and check for moisture, pests, or the condition of any existing insulation. From that visit we write a fixed price before any work starts, so you know the total cost upfront with no changes added later.
Which areas near Kennesaw do you cover?
Beyond the city itself, we also serve nearby communities including Houston, Spring, The Woodlands, Katy, Pearland, and Humble. If your home falls in one of these service areas, we can schedule the same inspection and written estimate process we use here.
What happens to my old insulation before new material goes in?
If your existing insulation is compressed, contaminated, or contains vermiculite, we remove and dispose of it before installing anything new. If it is simply thin but otherwise in good condition, we can often add new material on top of it, which keeps the job faster and less expensive.

What Kennesaw Customers Say
"Good honest work on the attic. The price was a little higher than one online quote, but Walt is the one who actually showed up and the one whose name is on the truck, and that was worth it to us."
- Helen Tran"Radiant barrier and new insulation in one visit. Walt explained what the foil actually does and what it does not, which nobody else bothered to. Electric bill in July was the lowest it has been in this house."
- Nadia Haddad"Air sealing first, then blown-in over the top. He found a bathroom fan venting straight into the attic and fixed that too. Written price before they started, same price when they finished."
