What Southeast GA Homeowners Say About Coastal Synergy
"Carlos Martinez and the Coastal Synergy crew were incredible. Our power bills last summer were hitting $420/month. After they spray foamed our roof deck and topped the attic, our bill dropped to $245 during peak July heat. Carlos arrived on time, walked us through the thermal camera tests, and didn't leave a single scrap of dust."
Derrick Henderson
Homeowner in Statesboro, GA
"We had damp, musty smells coming up through our hardwood floors. Coastal Synergy came out, encapsulated our entire crawlspace with a heavy white liner, sealed the foundation vents, and put in an energy-efficient dehumidifier. Our home smells fresh, feels 10 degrees cooler, and our floors don't cup anymore!"
Amanda & Thomas Vance
Property Owners in Savannah, GA
"As a GC, you need subcontractors who communicate clearly and show up when they promise. Coastal Synergy handles our spray foam and blown-in fiberglass packages across the Lowcountry. Their prices are fair, their prep work is meticulous, and inspectors pass their work the first time every time."

FAQ
Insulation & Crawlspace Questions, Answered by Coastal Synergy
Straight answers on spray foam, energy savings, and crawlspace moisture before you book your free estimate.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, expands rapidly to air-seal attic rafters, and offers superior acoustic dampening. Closed-cell spray foam is rigid, rock-hard, adds structural strength, and acts as a Class II vapor barrier—making it ideal for crawlspaces and metal buildings.
How much money can I save on my electric bill?
Homes in Georgia lose up to 40% of conditioned air through attic leaks and unsealed crawlspaces. Upgrading with closed or open-cell spray foam routinely lowers monthly electric bills by 25% to 40%.
Why encapsulate my crawlspace?
Open vents let humid summer air into cool crawlspaces, creating moisture condensation that causes mold and floor joist rot. Encapsulation seals off ground moisture with a heavy vapor barrier and maintains humidity below 55%.
