About Spray Foam Charleston

Who we are.

We work the Charleston metro the way a local outfit does: crews from around here, installs scheduled around real demand instead of a booking calendar, and a phone answered by someone who knows what a rim joist is.

We are not a national call-center brand, and we don't quote from a screen. The pitch leads with verification for a simple reason: an airtightness number is the only honest scoreboard in this trade, and you don't get one without walking the actual house.

How we work.

Step one is the assessment: we come out, look at the actual assembly wherever the project lives (attic, crawl, roof deck), measure what's there, and write the quote from evidence rather than guesswork. Step two is the install: prep done first, foam sprayed to spec, depth verified, and the site cleaned before the crew leaves.

Step three is the standard most quotes skip: jobs finish with blower-door verification of the finished envelope, so the airtightness you paid for is a measured number, not a promise. As far as we're concerned, that's when the job is done.

Licensing + standards.

We operate as a registered residential specialty contractor (insulation installers classification) with the SC LLR Residential Builders Commission, the registration class South Carolina requires for insulation installation work. The registration number publishes here once it's finalized for the site, and you can verify the class through the state registry today. Every install runs to the manufacturer's spec, from substrate prep to lift thickness to the listed applications we quote from.
