Marietta's mix of 1800s homes around the Square and sprawling 1970s-90s two-stories on wooded slopes over daylight basements face a common insulation problem: hot attics that bake at 130-150°F in summer, damp crawl spaces fed by red-clay moisture, and closed wall cavities that were never insulated when the house was built.
Atlanta Spray Foam Insulation has served Marietta (30060) and the surrounding Atlanta area since 2012, helping homeowners and property managers seal the gaps that cost money and comfort. We spray foam attics, crawl spaces, rim joists, and closed walls, and we remove and replace insulation that has failed or absorbed moisture. We show up with a truck and a crew that knows the neighborhood, not a trailer from out of state.
Spray Foam Insulation in Marietta (30060)
Marietta's older homes around the historic Square often sit on brick piers above vented crawl spaces where humidity and condensation are constant. The newer two-stories on the slopes have vaulted great rooms and finished rooms over garages that never reach temperature because the attic above them is uninsulated or stuffed with aged fiberglass that has settled and lost its R-value. In both cases, an air handler and ductwork sit in a vented attic that swings from 130-150°F in summer to near-freezing in the rare hard winter. Spray foam seals the leaks that fiberglass misses, controls humidity in crawl spaces, and stops the temperature swings that make a room uncomfortable no matter how hard the HVAC works.
Closed-cell foam is the right choice for crawl spaces and rim joists where moisture pressure is high and the space is tight. Open-cell foam works well in attics where cost matters and ventilation is good. Wall injection foam fills the empty cavities in older homes without tearing down the drywall. We measure each job on site, specify the R-value and thickness in writing, and use the correct foam for the job. Our team is fully insured with general liability and workers' compensation coverage.

How a Job Works in Marietta
We start with a free on-site assessment. You show us the attic, crawl space, or wall cavity that needs work, and we walk through what we see. We measure the area, ask about the current condition (is the insulation wet, settled, or contaminated?), and explain what has to happen before we spray. If old insulation has to come out first, we price that separately and do it honestly. We then provide a written estimate that names the R-value, thickness, square footage or board footage, and the total cost.
On the day of the work, our crew sets up mechanical ventilation in the space being sprayed. We apply the foam at the correct thickness in controlled passes, maintaining the manufacturer ratio and drum temperature. Spray foam cures as it hardens, and we observe a re-entry window of twenty-four to forty-eight hours before the space is occupied again. For homes in Marietta where the attic is tight and access is difficult, we plan the job carefully and work methodically. For crawl spaces, we seal rim joists and band joists first, then foam the floor deck or the crawl space walls depending on the moisture condition and your goals.
When the work is done, we remove all debris, sweep the space clean, and walk through with you to confirm the job is complete. You get a record of what was sprayed, where, and to what thickness.
Attic spray foam in Marietta typically runs from $1.50 per square foot for open-cell foam on top of existing insulation, to higher costs if old fiberglass has to be removed first. A 1,500-square-foot attic with removal and closed-cell foam can run $4,000 to $7,000 depending on access and the R-value specified. Crawl space foam starts at $2,500 for a small space and scales with square footage and the depth of the crawl. Rim joist and band joist sealing starts at $650 and covers the perimeter of your foundation. Wall injection foam for a closed cavity runs from $2 per square foot. Insulation removal alone starts at $950. The main cost factors are the area to cover, the R-value and thickness required by your local energy code, whether the foam is open or closed cell, what existing insulation has to come out, and how tight the access is.
