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

Comfort Summerville Insulation Company is an insulation contractor working in Hanahan, SC. We insulate and air seal attics, crawl spaces and walls, and we handle the prep first, like pulling out soaked or dirty old material.

Insulating Hanahan houses with water close by

Hanahan sits at the south end of Berkeley County, and its west and south city limits run right along the Charleston County line. Several neighborhoods have tidal water behind them, and Goose Creek Reservoir sits in the middle of the city, so on our jobs here the water is rarely far from the house. We're a Summerville insulation contractor, and we do the same work in James Island and Goose Creek.

Most calls here are about an upstairs that runs hot, a drafty room over the garage, or an older house someone just bought. With water this close, we check the attic and the crawl space for moisture before we add anything, because fresh insulation over a wet spot just hides it.

What sets the price and the schedule

The price comes down to how big the attic or crawl space is, how easy it is to get into, how many inches are already up there, and whether old material has to come out first. Air sealing, which means closing the gaps before we insulate, adds work, and foam costs more than loose fill. The schedule turns on the same things, plus whether a spray foam job means you're out of the house for a while. Your own number comes from someone looking at your space, so I come out and look at it myself.

Foam or loose fill in your attic

Foam costs more, but it seals air while it insulates. For most attics, we'd rather seal the gaps around can lights, pipes and the hatch, then top up with blown-in, which is loose fill blown through a hose, because that usually gets you more for the money. The exception is an attic where your ductwork lives, since foam there brings the ducts inside the insulated space. Either way, we keep the eave vents clear so the attic can breathe, and we keep the edges as deep as the middle. Our installers do the work, and I check it over before we call it done.

Crawl spaces and cold floors

Cold floors are a common call here, and with tidal water behind so many neighborhoods, the crawl space is the first place we look. We check for soaked insulation, droppings, leaks and loose wiring before anything new goes under the floor, because laying fresh material over that leaves the problem in place. If it's a plumbing or electrical job, I'll tell you it belongs to another trade before it's ours. Basements are uncommon around here, but if your house has one, basement insulation follows the same order, with the problems fixed first and the insulation after.

Insulation questions from Hanahan homeowners

Do I need a permit to insulate my attic in Hanahan?

The state's permit exemption for homeowners doesn't settle it, because its list covers work like fences, driveways and painting on your own house, not insulation. Hanahan sits near the Berkeley and Charleston county line, and which office covers a job depends on your address, so we sort that out before we start and handle any permit the job needs.

How do I know an insulation contractor in SC is properly licensed?

Ask which state board licenses or registers them. South Carolina's Residential Builders Commission covers residential builders and specialty contractors, and specialty trade work it regulates needs registration or licensure once the job runs over $500. We're licensed and fully insured, and any contractor you're weighing should be able to tell you where they stand with the state.

How do I check my flood zone in Hanahan?

Type your address into Berkeley County's FEMA flood map or the SCDNR Floodplain Map Viewer, which can switch between preliminary and current maps where new ones exist. It's worth knowing before crawl space work, because a low lot near tidal water tells us how closely to look for moisture under the house.

Do we have to leave the house while you insulate?

For blown-in attic work, usually not, since the crew stays up in the attic. Spray foam is different, so you, the kids and the pets stay out until the re-entry time, the point when it's safe to come back, which depends on the foam we use. I'll tell you that up front so you can plan around it.
