Thunderbolt's waterfront homes sit where the marsh meets the humid coastal air, and that moisture finds its way into crawl spaces, rim joists, and attics year-round. Older frame houses on raised foundations and newer construction alike pull damp air through vented foundations and attic spaces, and by mid-summer your cooling bill shows it. Savannah Spray Foam Insulation has been sealing and insulating homes in Thunderbolt and across the Savannah area since 2010, and we know exactly where the leaks are in a 31404 house.
Homeowners in Thunderbolt call us when a room stays hot no matter how hard the AC runs, when they see condensation or dampness in the crawl space or attic, or when an older home's energy bills have climbed beyond reason. We show up with a truck, not a promise. We measure, we spec the R-value and thickness on paper, and we tell you what the job costs before we spray a drop.
Spray Foam Insulation in Thunderbolt (31404)
Thunderbolt's housing stock runs the full span: waterfront cottages and older frame houses on pier-and-beam foundations with open crawl spaces, mid-century brick ranches with slab-on-grade construction, and newer subdivisions with stick-framed walls and vented attics. The marsh and tidal creeks nearby mean humid coastal air is the baseline condition, and vented crawl spaces and attics pull that moisture in steadily from May through September. Rim joists and band joists in older homes are the weak point, condensing and staying damp. Attics here bake through long cooling seasons, and if your ductwork runs through an unconditioned attic, you are losing conditioned air to the heat before it reaches the rooms. Closed walls with no cavity insulation are common in older frame construction, and they leak both air and energy. We seal and insulate the spaces that matter: attics with closed cell or open cell foam, crawl spaces with full coverage to stop moisture and air intrusion, rim and band joists that take the brunt of coastal humidity, walls with injection foam where we can reach them, and the air leaks around everything else.
Since 2010, we have worked on the full range of Thunderbolt properties, from historic waterfront homes to new construction. We are fully insured, and we show up on time with a written estimate that names the R-value, thickness, and price before we start.

How a Job Works in Thunderbolt
We start with a free on-site assessment. We walk your attic, crawl space, or the walls you want sealed. We look at what is there now, what has to come out, how thick we can spray, and what the local code requires. We measure the area, we spec the R-value and thickness on the estimate, we price it honestly, and we answer your questions. No surprises.
When you say go, we show up with the rig and crew. If there is old insulation that has to come out first, we remove it and haul it. We set up mechanical ventilation so the air moves while the foam cures. We spray to the thickness we promised, in passes that let the material set up right. We do not cut corners on ratio, drum temperature, or application technique. The work takes anywhere from a few hours to a day or two depending on what we are covering. Your home stays occupied if you want it to, and we tell you exactly when the space is ready to use again, typically twenty-four to forty-eight hours after we finish.
We clean up after ourselves. You get a walkthrough, and the job is done.
Pricing for Thunderbolt jobs depends on what you are insulating and what has to happen first. Attic spray foam runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, and the choice depends on your attic ventilation setup and local code. Crawl space spray foam, which is common in Thunderbolt, starts at $2,500 and covers the rim joist, band joist, and foundation wall. Rim and band joist sealing alone starts at $650. Wall injection foam for closed cavities runs from $2 per square foot. If old insulation has to come out first, removal runs from $950. The real cost drivers are the area to cover, the thickness and R-value you need, whether you choose open or closed cell, and whether we are removing contaminated or failed insulation before we spray.
