Kennesaw's 1980s and 1990s subdivisions sit on red-clay Piedmont slopes with vented crawl spaces and attics that climb to 140 degrees in July and August, and those bonus rooms and finished spaces over the garage rarely cool down or heat evenly no matter what the thermostat says.
Atlanta Spray Foam Insulation has been sealing and insulating homes across the Atlanta area since 2012, and we know exactly why homeowners in Kennesaw (30144) call us: a room that won't reach temperature, an attic or crawl space that sweats in the humidity, or an insulation job that has to be done right the first time because access is tight and the work is expensive to redo. We serve Kennesaw and all the surrounding areas with spray foam insulation, air sealing, and insulation removal and replacement.
Spray Foam Insulation in Kennesaw (30144)
Kennesaw's housing stock is dominated by two-story frame homes built between 1985 and 2010, most of them with vented attics, ductwork routed through those attics, and a finished bonus room or master suite over the garage that was never designed to be comfortable. The red clay and the tree canopy mean humidity is constant, and a vented attic full of fiberglass batts or blown-in cellulose will absorb moisture all summer long. Crawl spaces under these homes are vented to the foundation, which means humid air flows in from outside, condenses on cold ductwork or rim joists in winter, and leaves the insulation damp and useless. Wall cavities in many of these homes are empty or partially filled, and no amount of blown-in cellulose will seal air leaks the way closed-cell foam does.
Spray foam insulation solves all three of these problems at once: it seals the air leaks that make rooms uncomfortable, it creates a vapor barrier so moisture cannot condense inside the insulation, and it holds its R-value year-round in Kennesaw's humid subtropical climate. We have been installing spray foam in attics, crawl spaces, walls, and rim joists across the Atlanta area since 2012, and we know how to read a Kennesaw home and match the foam type and thickness to the space, the use, and the budget.

How a Job Works in Kennesaw
We start with a free on-site assessment. We walk your attic, crawl space, walls or garage with you, take measurements, and talk through what you are trying to accomplish: a room that won't cool, a condensation problem, or an older insulation job that has failed and has to come out. We leave you with a written estimate that names the R-value, the foam thickness in each space, whether we are using open-cell or closed-cell foam, and the total cost. No surprises, no upselling.
On the day of the work, our fully insured crew sets up mechanical ventilation, seals off occupied spaces, and sprays the foam to the thickness and density specified in the estimate. If you have old insulation that has to come out first (damp batts, contaminated cellulose, or failed foam), we remove it, haul it away, and inspect the substrate. We do not spray over wet wood, active leaks, or contaminated surfaces. If the moisture has to be fixed first, we say so and walk you through the options. Once the foam is sprayed and has cured for 24 to 48 hours, we clean up, remove the ventilation setup, and do a final walkthrough with you.
Pricing for spray foam insulation in Kennesaw depends on the area you are covering, the foam type (open-cell or closed-cell), the R-value and thickness you need, and whether old insulation has to come out first. An attic top-up in a Kennesaw home typically runs from $1.50 per square foot for open-cell foam to $1.20 per board foot for closed-cell foam. A crawl space job starts around $2,500. Wall injection foam runs from $2 per square foot. Rim joist and band joist sealing starts at $650. If you have old insulation that needs removal, add $950 and up depending on the volume and condition.
