Insulation Contractor in Hanahan, SC - Attics and Crawl Spaces Done in Order

We check with the office that covers your address before we start, and we take care of any permit the job calls for. South Carolina lets an owner skip the permit application for a listed set of work on their own home, like fences, driveways, painting and similar finish work, and each city or county reads and enforces the building code its own way. Hanahan's edges run along the Charleston County line, so the local building official for your address is the one who settles code questions.

Residential specialty trade work over $500 needs a state registration or license, and the state's Residential Builders Commission is the board that licenses and registers residential builders and specialty contractors. Its reach covers homes up to three floors. We're fully licensed and insured, and I'm happy to show you before any work starts.

The price comes down to what's already in your attic or crawl space and what has to happen before new insulation goes in, so I give you a figure after I've seen it. The size of the space, how many inches are up there, whether soaked or dirty material has to come out, how much air sealing it needs and whether we use foam or blown-in all move the number, and foam costs more. A tight attic or a low crawl space takes longer, which shows up in both the price and the schedule, and your written estimate lists each part so you can see what you're paying for.

Search your address on Berkeley County's FEMA flood map or the SCDNR Floodplain Map Viewer, and either one will show your flood zone. The county map shows flood data only, not property lines, and the state viewer lets you switch between the current map and a proposed one where new maps are in the works. With tidal water behind several Hanahan neighborhoods, it's worth knowing before we plan what goes under your floor.

Usually not, unless your ductwork runs through the attic. Foam costs more and seals air while it insulates, but in most attics, sealing the gaps around lights, pipes and the hatch and then topping up with blown-in, loose fill sent through a hose, gets you there for less. When the ducts or the air handler live up there, foam sprayed on the underside of the roof brings them inside the conditioned part of the house, and that's when I'll recommend it.

You, your kids and your pets stay out while we spray and until the re-entry time has passed, which is the wait the foam maker sets before people can come back inside. I'll tell you that time for the product we're using when we go over your estimate, so you can plan where to be. Blown-in and air sealing jobs usually don't need you out of the house.
