Snellville's 1980s and 1990s ranches and two-stories sit on sloped red-clay lots over vented crawl spaces, with air handlers and ductwork routed through attics that bake at 130 to 150 degrees from May through September. Cold floors over the crawl space and hot upstairs rooms are the signature complaint we hear from homeowners in 30078, and they are almost always fixable with spray foam insulation and air sealing.
Atlanta Spray Foam Insulation has served Snellville and the surrounding Atlanta area since 2012. We know the building stock here: we know why your bedroom stays hot when the downstairs is cool, why your crawl space stays damp, and what has to happen first to make it right. We show up with a crew that stays through the job, we give you a written estimate with R-value and thickness specs, and we leave your property clean.
Spray Foam Insulation in Snellville (30078)
The 1980s and 1990s construction that defines Snellville brought us two-story homes with vaulted great rooms, finished rooms over garages, and two-story foyers. Those open floor plans and cathedral ceilings are beautiful, but they create dead zones for HVAC ductwork. The air handler sits in a vented attic that reaches 140 degrees in midsummer, and the ducts running through it lose conditioning before the air ever reaches the upstairs bedrooms. Meanwhile, the crawl space underneath stays humid year-round because the vented foundation can't keep up with Atlanta's subtropical climate. The result is a cold first floor and a second floor that never cools, and a cooling bill that climbs every summer.
Spray foam insulation solves this by sealing the attic and the crawl space at the source. We spray closed-cell or open-cell foam directly onto the roof deck to keep the attic temperature down and the ductwork in conditioned space. We seal the rim joist and band joist where the floor frame meets the foundation wall, and we spray the crawl space walls to stop humidity from rising into the floor above. Every job starts with a free on-site assessment so we can see what you are working with and price it honestly.

How a Job Works in Snellville
We start with a free on-site visit. We walk your attic, crawl space or walls, measure the area to be covered, check for moisture or contamination that has to be fixed first, and talk through whether open-cell or closed-cell foam makes sense for your use. We give you a written estimate with the R-value and thickness we are specifying, the area in square feet or board feet, and the total price. No surprises, no upselling.
On the day of the work, we set up mechanical ventilation in the space being sprayed and keep it running through the cure window. We spray the foam to the thickness specified in your estimate, allow it to cure, and then install the ignition and thermal barriers required by code. If insulation has to come out first, we remove it and haul it away. We do not spray over wet, contaminated or leaking substrates. If the moisture has to be fixed first, we tell you that upfront and walk away if you want to spray anyway. That is how you know we are doing it right.
Once the foam is cured and the barriers are installed, we do a final walkthrough with you, answer any questions, and clean up the work area. The space is off-limits for 24 to 48 hours while the foam finishes curing, and we tell you that timeline before we start.
Pricing for spray foam insulation in Snellville depends on the area to be covered, the R-value and thickness you need, whether you choose open-cell or closed-cell foam, and what has to be removed or fixed first. An attic foam job in a typical Snellville ranch or two-story runs from $1.50 per square foot for open-cell to $1.20 per board foot for closed-cell, depending on the depth. A crawl space typically starts around $2,500 and goes up with the square footage and the condition of the space. Rim joist and band joist sealing starts at $650. Wall injection foam for closed cavities runs around $2 per square foot. If existing insulation has to come out first, add $950 and up depending on the volume. The best way to know what your job costs is to call us at (678) 931-8735 for a free estimate. We will measure the space, identify any moisture or contamination, and give you a firm price with R-value and thickness in writing.
