Hot upstairs rooms and drafts you can feel usually mean air is leaking in. We seal it with foam and insulate in the same coat.
Spray foam insulation in North Charleston is foam our crew sprays into walls, attic rooflines and crawl spaces, where it fills the space and stops air from moving through, so one coat seals the leaks and insulates at the same time.
Most of our calls come from older houses with a room over the garage that won't cool or a power bill that keeps climbing, and foam earns its place where air leaking in is the real problem. The price moves with how many square feet we cover, which foam goes in each spot, how thick it needs to be and whether old insulation has to come out first. The schedule turns on that same prep, the time your household plans to be away and the conditions in the space on spray day. I write the estimate out step by step, so you can see what goes where before you decide anything.
I look at every spray foam job myself before anything gets quoted, so the person pricing your house is the one who checked the attic, walls and crawl space. When the crew sprays, either I or a lead installer is on site with them.
I spent years as an HVAC service tech before starting this business in 2023, working on equipment in attics and crawl spaces. Over and over, the bigger problem was the leaks and thin insulation around that equipment, which is why we check those first.
We're licensed and fully insured, so you aren't the one carrying the risk while our crew works in your attic, walls or crawl space. When you're ready for a look, call (843) 278-0240 or send the form on this page.
We reply to every call and form within one business day, then I set a time to come out, look at the spots you want sealed and write your estimate on site, free, with no pressure and no obligation. It helps to have the rooms or walls you want insulated, your siding type and any gas or other fuel-burning appliances in mind when you call (843) 278-0240 or send the form.
North Charleston's Building Department issues building permits for new construction, renovations and residential projects, and city code requires the proper permits before anyone alters a structure. That list doesn't name insulation work by itself, so whether your spray foam job needs a permit is a question for the Building Department. We find out which city or county office covers your address, check what it asks for and take care of any permit your job needs before we start.
On jobs here we often find ductwork running through attics that were never sealed well, and a lot of brick houses, which changes the foam we'd choose for the walls. We're based in North Charleston and do the same work across the cities around it, including Hanahan and Goose Creek, and if your city isn't listed, call and ask.
A Department of Energy spray foam guide rates closed-cell foam as the preferred choice for walls in hot-humid climates, because it seals air and controls moisture vapor whether it fills the whole wall or is paired with other insulation. The same guide advises against open-cell foam in hot-humid climates where brick veneer sits over housewrap, the wrap sheet behind the siding. If your house is brick, ask us about closed-cell for the walls instead.
Everyone living in the house should be out while the foam is sprayed, and some makers of professional high-pressure foam recommend 24 hours before residents come back. That time can vary by product, so plan on a night elsewhere, and we'll go over the wait for the foam we're using. Other trades working in the house should be out during spraying too.
Spray foam insulation in the Charleston area usually costs about $1 to $5 per square foot. The low end usually means open-cell foam on an easy-to-reach roofline, and the high end usually means thicker closed-cell foam or a space that has to be cleared out before we spray. Your estimate lays it out spot by spot, so you can see what goes where.
South Carolina's residential specialty contractor rules include insulation installers, the trade that installs, alters and repairs insulating materials for temperature or sound control. The state counts a contractor as a residential specialty contractor when a property owner hires them for specialized trade work on a job over $500, and foam used as outside roofing falls outside the insulation trade. You can also ask about the crew's training, since installers certified by the Spray Polyurethane Foam Association carry a wallet-sized card.
Plan for fresh air before the foam goes in, because a tighter house can lose the outside air that keeps indoor odors down, and areas with fuel-burning appliances may need extra air exchange. That's worth going over with an HVAC design professional before the job is scheduled.
Schedule around the conditions in the space, because foam only goes in well when the air and surface temperature, the humidity and any moisture on the surfaces are right. On a muggy stretch that can mean adjusting the indoor conditions ahead of time or shifting the work day. We check those conditions before we spray and talk with you if they mean moving the date.
