Spray Foam Insulation in the Lowcountry – Energy Savings That Actually Stick
We seal and insulate your Charleston home in one shot — cutting energy bills up to 50%, keeping out humidity, mold, and allergens, and making your house quieter and more comfortable year-round.
Welcome
Hey neighbors — we’re Atlantic Spray Foam, a local, owner-operated crew right here in Charleston. TJ Anderson moved to the Lowcountry in 2008, fell in love with Charleston and the surrounding coast, and started this company to give folks better insulation than the old fiberglass or batt stuff that just doesn’t hold up in our humid coastal climate.
We take the time to understand your home — whether it’s a new build on Daniel Island or in Mount Pleasant, a historic single house or Charleston-style home South of Broad or in the French Quarter, or a Lowcountry-style home along the Ashley or Cooper Rivers — and we only use the highest-quality, American-made spray foam. Our goal? Slash your dependence on expensive energy, improve the air your family breathes, and deliver the most professional insulation service Charleston has seen.

Why Spray Foam?
If you’re a Charleston homeowner tired of high electric bills, stuffy rooms, or that musty crawl space smell, spray foam is a game-changer. Here’s what it does for Lowcountry homes:
Cuts heating & cooling costs up to 50% — perfect for our hot, humid summers and mild winters. Homeowner reports and case studies frequently mention savings of up to 50% on energy bills after professional spray foam installation.
Seals every crack, gap, and void — stops humid Lowcountry air from sneaking in and causing mold or high humidity problems.
Creates a quieter, more comfortable home — blocks outside noise from boats on the harbor, traffic on I-26 or Meeting Street, or weekend crowds downtown.
Improves indoor air quality — keeps dust, pollen, and allergens out so your family breathes easier.
Pays for itself — most Charleston homeowners see real savings on their next Duke Energy or SCE&G bill.
It’s not just insulation — it’s a permanent, one-and-done solution built for Charleston’s unique coastal conditions.
