Insulation contractor in North Charleston, SC - a cooler upstairs, gaps sealed first

We're based in North Charleston and insulate attics, crawl spaces and walls in the older houses here. We seal the leaks first so the new insulation isn't fighting a draft.

What we find in North Charleston attics and crawl spaces

Most of our calls here come from older houses where the upstairs runs hot, the room over the garage won't cool down or the power bill keeps climbing all summer. When I go up, I usually find a few inches of old insulation that's packed down, piled deep in the middle and thin at the edges, with open gaps around can lights, pipes and the attic hatch.

A lot of these houses also have the ductwork and air handler up in the attic, so leaks there cool the attic instead of your rooms. Underneath, sagging batts and damp crawl spaces make the floors feel cold, so we look at both ends of the house before deciding what's worth doing.

Insulation work we do on North Charleston houses

Most of our work here is attic insulation and attic air sealing, which means closing the gaps before any insulation goes down, because that's where older houses lose the most. Under raised floors that feel cold or smell musty, we do crawl space insulation and vapor barriers. When old insulation is soaked or full of droppings, removal comes first so the problem doesn't stay buried. Spray foam insulation makes sense where ductwork runs through the attic or the room over the garage won't stay cool. We also handle wall insulation, retrofit work in finished houses and small commercial buildings.

Working in North Charleston: licensing, permits and what sets the price

North Charleston has its own city government. Before any job starts, 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. On the contractor side, the state Residential Builders Commission licenses or registers residential builders and specialty contractors working on houses up to three floors, so it's fair to ask anyone you hire how they're licensed with the state. We're licensed and fully insured.

The price turns on how big the attic or crawl space is, whether old insulation has to come out first, how many gaps need sealing and whether you choose foam or loose fill. Those same things set how long we're at your house, along with how tight the attic is to move around in. The estimate lays out each step so you can see where your money goes. We do the same work in the cities around us, from Hanahan to Charleston, and if your city isn't listed, call and ask.

Why North Charleston homeowners call us

A former HVAC tech checks your ducts too

I spent years as an HVAC service tech before starting this business in 2023, so in your attic I look at the ductwork and equipment along with the insulation. Leaks around the ducts are often why the upstairs stays hot, and we seal them first.

The owner comes out and writes your estimate

I come out to look at every job and write the estimate myself, so the person pricing your house is the one who's been up in your attic. If your insulation is already in decent shape, I'll tell you the work can wait rather than sell you something you don't need.

Old material out and gaps sealed before insulating

We pull out soaked or dirty insulation, seal around can lights, pipes and the hatch, and keep the eave vents clear before adding anything new. Either I or a lead installer is on site for the whole job. Satisfaction guaranteed. Call (843) 278-0240 to set up a visit.

Questions North Charleston homeowners ask us

How much does attic insulation cost in North Charleston?

I can't give you a fair number until I've been in your attic, because the price follows what's up there. It depends on how much space there is, how many inches are already down, and whether any of it is soaked or full of droppings and has to come out. Air sealing adds work, but it's usually what stops the drafts, and foam costs more than blown-in loose fill. Call (843) 278-0240 and I'll come take a look.

How long will an insulation crew be in my attic?

Most of the time goes into the prep, not the new insulation. A clean, open attic that just needs topping up goes quickest. Pulling out old material, sealing around can lights and the hatch, and clearing buried eave vents all add time. We do those steps first, in that order, because insulation laid over a draft or a damp spot just hides it.

Do I have to leave my house during spray foam insulation?

Yes. With spray foam, you, your kids and your pets stay out until the re-entry time, which is when it's safe to come back inside. That time comes from the foam maker's instructions for the product we're using, and I'll go over it with you before the work day. With blown-in loose fill, which is blown through a hose, most people stay home and just keep clear of the work.

What is the best way to insulate an attic with ductwork in it?

When the ducts and air handler live in the attic, spray foam on the underside of the roof is often worth the extra cost. That keeps the equipment inside the insulated space, and the foam seals air while it insulates. Without ducts up there, sealing the gaps and topping up blown-in loose fill usually does the job for less.

Does a contractor working on my North Charleston house need a state license?

For larger jobs, yes. In South Carolina, anyone who builds, repairs or improves a house, or offers to, counts as a residential builder once the job costs more than five thousand dollars. Residential builders are licensed or registered by the state Residential Builders Commission. That applies to houses up to three floors and apartment buildings with no more than sixteen units, and commercial work falls under separate licensing.

Which building codes apply to insulation work in North Charleston?

North Charleston follows South Carolina's statewide building codes, which the state Building Codes Council adopts. The council also approves some changes for use only in named local areas, and those apply only after a local law adopts them. That's one reason we check with the office that covers your address before work starts.
