Insulation Contractor in Mount Pleasant, SC - Attics and Crawl Spaces Sealed Right

Your price is set by what's already in your attic or crawl space and which material the house needs, and the written estimate gives you that number before any work starts. Foam costs more because it seals air while it insulates, but on most attics, sealing the gaps and topping up the loose fill, the blown-in kind that goes in through a hose, is the better buy. Foam usually earns its price when your ductwork runs through the attic.

The Town of Mount Pleasant says work valued at $1,000 or less in material and labor doesn't need a building permit unless an inspection is required, though site plan approval from the city's planning department still applies. Past that, a permit can come into it, so we check with the city's permit office for your address before we start and take care of any permit the job calls for.

Yes, state law requires a current South Carolina license or registration for residential building and specialty contracting, and the city checks contractor licenses with the state's licensing department. Any contractor working in Mount Pleasant also needs a business license from the city, paid before work begins and every year after. We're fully licensed and insured, so ask us about it at the estimate.

If your house is in the Old Village, it may well be, because the city's local historic district covers a section of that neighborhood. The Historic District Preservation Commission reviews every exterior change in the district and has to approve it before work starts. Most insulation goes in from inside, but if a job would add or change vents on the outside, we bring that up at the estimate so it goes to the commission first.

The city's newer flood maps raised the design flood elevation, which is how far above the expected flood level a building is designed to sit, and that's the rule most homeowners hear about. For insulation, what matters more is that the city names two kinds of flooding, blocked or overwhelmed drainage and storm surge from tropical storms and hurricanes, and either one can soak a crawl space. We look for water lines and wet insulation under the house first, and wet material comes out before anything new goes in.

Usually it's thin insulation in the short walls beside the slanted ceiling and in the floor over the garage, plus air leaking in around the edges of the room, so it heats up faster than the rest of the house. We check those spots at the estimate, seal the gaps and fill what's thin, and in some rooms foam fits better because the space is too tight for loose fill.
