A lot of our Charleston calls come from older houses, where the attic insulation went in long ago, has settled to a few inches and has been walked on, patched or rained on since. The upstairs runs hot by afternoon, and the room over the garage is usually the worst of it.
The ground here sits low, and plenty of it is close to the water, so crawl spaces under raised floors breathe damp air. The cold floors people mention in winter usually trace back to a crawl space with little or nothing between the joists, and that damp is the first thing I look for under a Charleston house.
We reply to every call and form within one business day, with no pressure and no obligation. I'll set a time to come out to your Charleston house, go up in the attic and under the floor myself, and write up the estimate. Our installers start only once you've decided to go ahead.
(843) 278-0240In the older houses here, most jobs start with attic insulation, adding to settled material once the gaps under it are closed, or taking it out first when it's ruined. Under raised floors we insulate crawl spaces and put down vapor barriers so ground moisture stays out, and we use closed-cell foam, a dense foam that blocks moisture, where water is a real risk. We also do wall and retrofit insulation in finished rooms, and commercial insulation for landlords and small business owners.
Inside city limits, permit questions go to the City of Charleston, and its residential permit list names work like roofs, fences and decks without settling insulation either way, so 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. If one is needed, we can begin once the city shows it as issued and the placard is posted at your house, so that wait can set the start date. If a dumpster for old insulation has to sit in the street or on the grass strip by the sidewalk, that takes an encroachment permit from the city's Public Service Department. On your end, two things are worth checking about whoever you hire. State law requires a contractor license for residential trade work above a small dollar amount, while commercial work over $10,000 takes a General or Mechanical Contractor's license, and the other is the city business license covered in the questions below.
The price here turns on how big the attic is and how easy it is to reach, how many inches are already up there, whether old material has to come out first, and how many gaps around can lights, pipes and the hatch need closing before anything goes on top, the air sealing that keeps new insulation from fighting a draft. The schedule turns mostly on the permit question and on removal, and the estimate I write lays each step out so you can see what goes where. We come in from North Charleston for these jobs, the same crew that works in Goose Creek and the other cities around us.
I come out to every job, up through the attic hatch and under the floor if there's a crawl space, and I write the estimate, so nothing gets lost between whoever quoted it and the crew. Our installers then work with me or a lead installer on site.
I spent years as an HVAC tech in attics and crawl spaces before starting this business in 2023, and the real trouble was usually leaks and thin insulation around the equipment. So we seal gaps and fix damp spots first, and if a job can wait, I'll say so.
We're licensed and fully insured, and satisfaction guaranteed is the promise behind every job we do here. Before we leave, we pull out our hose lines and sweep up around the hatch. When you're ready, call (843) 278-0240 or use the form on this page.
I can't give you a fair number until I've been in your attic, because the price turns on its size, the inches already there and whether old material comes out first. Spray foam costs more because it seals air while it insulates, but sealing the gaps and topping up with blown-in insulation, loose fill blown through a hose, usually wins unless your ductwork runs up there. I'll come out, look and write it up.
For blown-in work you can usually stay home, but with spray foam everyone, kids and pets included, stays out until the re-entry time, the point when it's safe to come back, has passed. The foam maker's instructions set how many hours that is, and we tell you before the job. How long we're up there depends on how much comes out and how much sealing there is, which I'll know after the estimate.
Usually it's thin, uneven insulation and open gaps, not the AC. Older attics are often thin at the edges and deeper in the middle, which is backward, and hot air pushes in around can lights, pipe holes and the hatch. Buried eave vents make it worse, because the attic can't breathe and moisture starts showing in the framing.
Look it up on the city's interactive GIS map, linked from the city's Permit Center. If your address isn't on that map, the city points you to other GIS maps, such as Charleston County's. It matters because city limits decide whether the city's permit and business license rules apply to your job.
Yes, any contractor doing business inside city limits needs a city business license, even with no office in the city. That covers contractors from outside the city, like us in North Charleston. It's fair to ask whoever you hire to show theirs.
Yes, the city's Non-licensed Owner Intent to Build form lets homeowners get residential single-family permits, except fuel-gas permits. If you'd rather not, we take care of any permit your job needs, as described above.
Zones AE and VE are the city's high hazard flood zones, inside the regulated Special Flood Hazard Area, while X is low hazard and X Shaded is moderate, both outside it. The city explains the zones on its flood zone page. For insulation, a house in or near a high hazard zone usually needs its crawl space checked for moisture first, and closed-cell foam usually holds up better where water can reach.
