Spray foam insulation in Cumming, GA, does something batt insulation can’t. It air seals and insulates in the same pass, which counts for a lot in a climate that spends five months of the year pushing humid air through every gap in the building envelope. Anthem Insulation & Home has been installing foam across Forsyth County for more than ten years, and it’s the material we point homeowners toward when air leakage is the real reason behind a high power bill. Foam is one of the insulation services in Cumming, GA, we run from the Woodstock office.
Open-cell spray foam expands to around a hundred times its liquid volume, runs roughly R-3.7 per inch, and stays soft and permeable to water vapor. It’s the less expensive of the two by a wide margin, and it does well on attic roof decks and interior walls where sound dampening is a bonus.
Closed-cell is denser, about R-6.5 per inch, and stops vapor rather than letting it pass. The density adds rigidity to a wall assembly as well. In crawl spaces, rim joists, and anywhere the assembly might see bulk water, closed-cell is what we install.
Depth changes with the material. Georgia’s energy code calls for R-38 in attics in this climate zone, which takes roughly ten inches of open-cell or six inches of closed-cell. You can read more about the two types of spray foam and where each one fits.
The most common job we run in Cumming is the attic roof deck. Plenty of Forsyth County homes have the air handler and the entire duct run sitting in a vented attic that pushes past 130 degrees in August, and every foot of that ductwork is losing conditioned air on the way to the registers. Foaming the underside of the roof deck brings the attic inside the conditioned envelope, so the equipment is no longer working in an oven. Homeowners tend to notice the difference in upstairs comfort before they see it on the bill.
Rim joists are the other high-value target. They leak badly, they’re hard to seal any other way, and they take little material to do properly. Wall cavities during a remodel, bonus rooms over garages, and crawl spaces all take foam well.
Foam is a chemical reaction, and it’s unforgiving about conditions. Substrate temperature, ambient humidity, and the ratio between the two components all affect whether it cures correctly. Sprayed too thick in a single pass, it traps its own heat and can scorch. Sprayed on a deck that’s too cold, it pulls away from the surface within a season.
Crews mask off everything that isn’t getting sprayed, apply the material in controlled lifts at the specified thickness, and trim flush where framing needs to stay exposed. The house has to be vacant during application and through the ventilation period afterward, which is usually around 24 hours. We schedule around that rather than surprising you with it on the day.
Every project starts with a free home energy audit. That’s what tells us where the leakage actually is, and whether foam is the right call or just the expensive one.
New customers get 10% off insulation services. Veterans and first responders get 10% off as well. Foam costs more per square foot than the alternatives, and financing is available if you’d rather spread the project across a few years instead of paying it up front.
Treating your home like our own is the standard we hold crews to. On a foam job that shows up in the masking, the cleanup, and the willingness to tell you when a cheaper material would serve you just as well.

Sawyer and his team did an exceptional job with our blown insulation project. Our project was unique as the team had no access to the attic and had to work through speaker holes and can light holes. The team was respectful of all of our belongings, laying down tarps and plastic. The team was patient and happy to work with all my pickiness and oversight. Definitely recommend Anthem Insulation for your home or business.
I had a great experience working with them. The price they quoted was lower than I was expecting. They were not pushy, even though it took me 3 months to get around to scheduling the work after the estimate. The spray insulation work was high quality, and looks great.
I was unexpectedly not able to be home when they showed up to do the work so I left the door unlocked and the check on the counter. They were super professional, and took care of everything without me needing to be there. Couldn’t ask for anything more, I’d definitely recommend this place.
