Atlanta's homes sit on red-clay Piedmont over vented crawl spaces and daylight basements, with air handlers and ductwork baking in attics that hit 150 degrees from May through September. Whether you're in a 1920s Craftsman bungalow on brick piers in Virginia-Highland or Inman Park, a 1950s brick ranch in Brookhaven, or a newer two-story with a finished room over the garage that never cools, your insulation and air sealing strategy has to match your specific building, your foundation type, and Atlanta's humid subtropical climate.
Atlanta Spray Foam Insulation has served homeowners and property managers across the city and surrounding areas since 2012. We show up with a free on-site assessment, write estimates that specify R-value and thickness, and leave your property clean. We know Atlanta's neighborhoods, its building stock, and the moisture and temperature challenges that drive every insulation decision in this city.
Spray Foam Insulation in Atlanta (30303)
Atlanta's insulation problems are shaped by its building era and the way homes are built here. Inside the Perimeter, 1900s-1930s Craftsman bungalows and mill cottages sit raised on brick piers above damp crawl spaces, with lap siding over empty wall cavities and vented attics. Beyond the Perimeter, 1950s-60s brick ranches have flattened original attic fill and poor air sealing around the rim joist. Newer subdivisions in Alpharetta, Roswell, Johns Creek and Marietta run two-stories with two-story foyers and vaulted great rooms, where the finished room over the garage or at the end of a duct run never reaches temperature because the attic above it is poorly insulated and the wall cavities are hollow. Across all of it, humidity and crawl space moisture drive every decision. An air handler and its ductwork in a vented attic that hits 130 to 150 degrees in summer loses conditioned air through uninsulated or poorly insulated ducts, and that loss shows up on your cooling bill. Damp insulation in a crawl space or condensation on rim joists and band joists means moisture is moving through those spaces, and wet insulation does not insulate. Closed-cell spray foam stops air and moisture movement both. Open-cell foam insulates and is vapor-permeable, which is the right choice in some applications and the wrong choice in others. We assess your specific building, your foundation, your attic configuration and your moisture profile, and we recommend the foam type and air sealing approach that works for your home.
Our team has been installing spray foam insulation in Atlanta and the surrounding areas for over a decade. We are fully insured, and we work in occupied homes with proper ventilation and a stated re-entry window so you know when the space is safe to use again.

How a Job Works in Atlanta
We start with a free on-site assessment. You describe what brought you to us: a cooling or heating bill that has become unaffordable, a room that never reaches temperature, visible moisture or damp insulation in an attic or crawl space, or insulation that has failed and has to come out before anything else can happen. We walk the space, measure the area, identify what needs air sealing, and determine whether existing insulation has to be removed first. We give you a written estimate that specifies the R-value, thickness, and foam type we recommend, along with a firm price.
On the day of the work, our team sets up mechanical ventilation and manages the cure window. We spray foam to the specified thickness in multiple passes, controlling the ratio and drum temperature so the foam cures properly. We air seal rim joists, band joists, rim board penetrations, and the edges of the foam where it meets the existing structure. In an attic with ductwork, we foam around the ducts. In a crawl space on brick piers, we foam the rim and band joists and the walls, leaving the inspection strips that your pest bond requires. In a wall cavity retrofit, we inject foam into the closed cavity from the exterior or interior. We do not spray over wet, contaminated or leaking substrates. If your crawl space has standing water or your attic has an active roof leak, we fix the moisture first or we walk away.
When the foam is cured, we clean up the site and walk through with you. We leave your property clean and your space ready to use after the re-entry window closes, typically 24 to 48 hours.
Pricing for spray foam insulation in Atlanta depends on the area to cover, the R-value and thickness you need, the foam type (open or closed cell), and whether existing insulation has to be removed first. Attic foam typically runs from $1.50 per square foot for open-cell work to $1.20 per board foot for closed-cell, with the final cost determined by the depth and coverage your attic requires. Wall and injection foam retrofit runs from $2 per square foot. A crawl space project starts around $2,500 and scales with the size of the space and the wall area to cover. Rim and band joist sealing starts at $650. If you have old, wet, or contaminated insulation that has to come out first, removal runs from $950, and the cost of the new foam goes on top. We give you a free estimate by phone at (678) 931-8735, and we schedule an on-site assessment so we can write a firm price with R-value and thickness specified.
