Wilmington Island sits along the tidal marsh where the Savannah River spreads wide, and that proximity to water defines every insulation challenge your home faces. Your attic and crawl space pull in damp coastal air for most of the year, and that moisture works its way into walls, rim joists, and band joists in ways that standard blown-in insulation cannot stop.

Savannah Spray Foam Insulation has served Wilmington Island (31410) and the Savannah area since 2010. We know the raised crawl spaces under older frame homes along Victory Drive and Whitemarsh Island Road, the vented attics that bake through the long cooling season, and the moisture that never really stops in a climate zone 2A Lowcountry home. When a homeowner in Wilmington Island calls us, it is usually because a room over the garage stays too hot, the attic insulation has gone damp, or the cooling bill has climbed beyond reason. We spray foam the right spaces, seal the air leaks around them, and leave your home tighter and drier.

Spray Foam Insulation in Wilmington Island (31410)

Wilmington Island's housing stock is a mix of mid-century frame homes on raised crawl spaces and newer construction on slab, with attics that carry ductwork and roofing that bears the weight of the summer sun and hurricane-season wind. The vented crawl spaces and attics that made sense when homes were built to breathe now work against you. They pull in humid air off the marsh, and that moisture condenses on cool surfaces, soaks into fiberglass batts, and rots rim joists and band joists that you cannot see until the damage is already there. Closed-cell spray foam stops that moisture at the air barrier. Open-cell foam in an attic lets the wood dry to the inside, which works well when the attic is unconditioned and you are not running air conditioning through it. We assess what you have, what the moisture is actually doing, and what foam type fits your home and your use.

Our team has been serving Wilmington Island and the surrounding Savannah area for over a decade. We understand the local building stock, the humidity that never truly leaves, and the difference between a quick spray and an installation that holds up through hurricane season and twenty years of Lowcountry weather.

How a Job Works in Wilmington Island

We start with a free on-site assessment. You walk us through the problem: a cold room, a damp attic, a crawl space that smells like mold, or an energy bill that has become unaffordable. We look at the space, check for moisture, identify what is already there, and tell you plainly what has to happen first. If the insulation is wet or contaminated, it comes out before we spray anything new. If there is standing water or active leaks, we walk away until those are fixed. Moisture first, or we do not proceed.

On the day of the work, our fully insured crew arrives with equipment and materials. We protect your floors and belongings, seal off the space we are spraying, and run mechanical ventilation during the cure. Spray foam releases odor as it cures, and we keep the air moving. You can usually re-enter the space within twenty-four to forty-eight hours, depending on thickness and temperature. We provide a written estimate with R-value and thickness specifications before we start, so you know exactly what you are getting.

When we are done, we clean up. Your property leaves the way it came, minus the air leaks and the damp insulation.

Pricing in Wilmington Island depends on what needs to be done. An attic foam job typically runs from $1.50 per square foot for open-cell foam to $1.20 per board foot for closed-cell, depending on the R-value you need and the thickness we have to spray. A crawl space job starts around $2,500 and climbs with the square footage and the moisture prep work required. Wall injection foam in a closed cavity runs from $2 per square foot. If old insulation has to come out first, add $950 and up for removal. Rim and band joist sealing starts at $650. The real cost drivers are the area to cover, the R-value and thickness your space needs, whether the substrate is wet or contaminated, and what has to be removed or prepped before we spray. Call us at (912) 483-1976 for a free estimate. We measure on site, assess the moisture and the substrate, and give you a firm price with R-value and thickness written down.

Why does my attic in Wilmington Island get damp even though it is vented?
A vented attic in the Lowcountry pulls in humid air off the marsh and the river. In summer, that warm, damp air hits the cool underside of your roof deck and condenses. The insulation soaks it up. Closed-cell spray foam on the roof deck stops that moisture at the air barrier. The attic stays drier, and the wood stays sound.
My crawl space under my Wilmington Island home smells musty and the insulation feels damp. What do we do first?
First, we find out why it is damp. Is there standing water, a plumbing leak, or just humidity from the marsh? If there is standing water or an active leak, that has to be fixed before we spray foam. If it is just humidity, we seal the rim joist and band joist, and sometimes we spray the crawl space floor or walls with closed-cell foam to stop the moisture from rising. Call us at (912) 483-1976 and we will assess what is actually happening under your house.
What does attic spray foam cost in Wilmington Island?
Attic foam typically starts around $1.50 per square foot for open-cell foam, depending on the R-value and thickness. If you need higher R-value or closed-cell foam, the cost rises. The real factors are the square footage of your attic, whether old insulation has to come out first, and how thick we need to spray to meet your target R-value. A free on-site estimate will give you a firm price.
Who inspects spray foam insulation in Wilmington Island and what are the R-value and thickness requirements?
Chatham County building code governs attic ventilation, ignition barriers, and thermal barriers. The rules depend on your specific address and the building era. The building official at Chatham County has final say on what applies to your home. Your local building department can tell you what is required. Check with Chatham County through their official site at https://www.chathamcounty.org to confirm what applies at your address.
Can we stay in the house while you spray foam the attic?
Yes. We run mechanical ventilation during the cure, so the smell stays contained. You can usually re-enter the space within twenty-four to forty-eight hours. If you have an HOA in Wilmington Island, let us know, because some communities have rules about exterior work or equipment staging. We coordinate around your schedule and any community guidelines.
Is your crew fully insured?
Yes. We carry full general liability and workers' compensation insurance. You can ask to see our certificate of insurance before we start any work. Protecting your home and our team is not optional.
When should I schedule spray foam insulation work in Wilmington Island?
Summer in Wilmington Island is brutal on an uninsulated attic. If you have a room that never reaches temperature or an energy bill that climbs through June, July and August, spring is the time to call. Fall and early winter are also good windows before the holidays. Hurricane season runs June through November, so avoid scheduling during active storm activity. The sooner you seal and insulate, the sooner you stop losing money to air leaks and damp insulation.
