The real problem
Why humid air is the enemy, not R-value.
A humid house loses in two ways: air leaks carry heat and moisture through every gap, and insulation rated for temperature alone can't slow wet air. Airtightness is what moves first. We measure it, seal it, and only then talk about inches of insulation, which is why every job ends with blower-door verification instead of a shrug.
What we install
The spray foam services we install.
Closed cell on the roof deck, encapsulated attics, seal-off crawls, blown-in floors: these are the installs we run every week across the metro. Insulation removal lives one click away in the services hub for jobs that start with a cleanup.
Closed Cell Spray Foam
Two-pound, medium-density foam: R-6.5 per inch, moisture blocked outright, and real strength where the coast pushes hardest.
View Closed Cell Spray Foam ›Open Cell Spray Foam
Half-pound foam that air-seals and quiets a space for less: the honest pick for ordinary attic budgets.
View Open Cell Spray Foam ›Attic Encapsulation
Foam on the roof deck, ducts pulled inside the envelope, and a 130F attic turned into mild, usable space.
View Attic Encapsulation ›Crawl Space Encapsulation
Liner, sealed walls, and the right dehumidifier: musty crawls, damp floors, and marsh air fixed at the source.
View Crawl Space Encapsulation ›Air + Duct Sealing
Seal the gaps and the ducts first: the cheapest big win on the list, and the move every good install starts with.
View Air + Duct Sealing ›Blown-In Insulation
Loose fill to a real depth in a day, paired with proper air sealing so the R-value you buy actually lands.

Share your details
Send the five-field form or give us a call. Your address and a few lines about the symptoms are enough to get us moving.
Free on-site assessment
We come out, measure the space, check the assembly and any old insulation, and hand you a written quote with a real number. No obligation attached.
Install + blower-door verification
The install runs to spec, and then we prove it: a blower-door check on the finished envelope, so the airtightness you paid for is measured, not promised.
Costs
Know the numbers before you book.
Dollar ranges publish in exactly two places on this site: the estimate card below and our two cost guides. Everything else talks factors, because every house prices differently and we'd rather show you why than guess.
The card to the right carries the honest, sourced bands for crawl space encapsulation, attic encapsulation, and whole-home foam. Your real number comes from the free on-site assessment, and both cost guides carry the full method, per-board-foot pricing, and the sources behind every range.
| Scope | Estimated band |
|---|---|
| Crawl space encapsulationtypical range, SC average about $5,000Popular | $4,500 to $7,000 |
| Attic encapsulationopen vs closed cell swings the price | $4,000 to $9,000+ |
| Whole-home foambuilt from the on-site assessment | Priced per job |
Every home prices differently and the free on-site assessment gives your exact number. Bands sourced from CrawlSpaceCosts.com and HomeGuide; full sources on the cost guides.
Why us
Built for the Lowcountry.
National brands sell a calendar slot. We run local crews with written quotes, blower-door verification, and our SC registration wording published for anyone to check. Foam installs follow real demand here, so booking in July is as easy as booking in January.
Humidity-first, not R-value-first
Airtightness beats inches in this climate, because wet air is the leak that matters. We score the envelope before we quote the foam.
Blower-door verified
Every install finishes with a verified air-seal number instead of a promise. You see the result before we call it done.
Local crews, year-round windows
We live and work here, and foam installs follow real demand rather than a booking-season scramble. July schedules as easily as January.

Straight answers
Charleston spray foam questions, answered.
Are you licensed in South Carolina?
We operate as a registered residential specialty contractor (insulation installers classification) with the SC LLR Residential Builders Commission, the registration classification South Carolina requires for insulation installation work. Our registration number publishes here and on your paperwork once it's finalized for the site. You can verify the class through the state registry today, and we'll walk you through it anytime.
What rebates or tax credits do insulation jobs qualify for?
South Carolina's utility programs are the live opportunity: Dominion Energy SC pays insulation and air-sealing rebates to residential electric customers, and Duke Energy SC applies discounts on attic insulation upgrades through its approved-contractor program. We help you file the paperwork either way. The federal 25C credit wasn't extended past 2025, so we don't promise federal dollars on 2026 jobs; if that situation changes, the cost guides will say so first.
How long does a typical spray foam install take?
One to two days for most homes. Attic floors and crawl spaces often wrap in a single day, while whole-home and roof-deck jobs usually take a second day for prep and depth checks. Your written quote includes the install window before you commit.
Is spray foam safe, and when can my family re-enter the house?
Standard practice here is containment: the crew works in full protective gear, the work area stays sealed off, and people and pets stay out of the treated space until the foam has fully cured and the area is aired. For most residential jobs that means re-entry the next day. You'll get the exact window with your schedule.
What warranty comes with the work?
Two layers: the foam manufacturer's material warranty, which on major closed-cell brands runs for decades to a lifetime on the product itself, and our workmanship warranty on the installation. Exact term lengths are being finalized for launch, so ask when you book and you'll get the current terms in writing.
What areas around Charleston do you serve?
Charleston, Mount Pleasant, Summerville, North Charleston, West Ashley, James Island, Johns Island, Hanahan, and Goose Creek each have a page on this site, plus service to Isle of Palms, Folly Beach, Daniel Island, and the surrounding Lowcountry. Not sure your address is in range? Call and ask; if we can't serve you well, we'll say so.
