Drafty rooms, a hot upstairs or a power bill that keeps climbing? We find the hidden leaks, seal them and keep fresh air coming in.
Air sealing services in North Charleston close the gaps where air slips in and out of your house, around door frames, ducts and fans and wherever pipes, vents and wires pass through, so the air you pay to heat and cool stays inside. It's best done before any new insulation goes in, because insulation slows heat but doesn't stop air from moving through it.
Most people call us about a room that never feels right, like a hot upstairs, cold floors or the room over the garage, or about a power bill that keeps climbing for no clear reason. The cause is usually leaks you can't see, under the attic insulation or in the crawl space, and reaching them is what sets the price. That means how much insulation we have to pull back, how easy the attic is to get into, how many holes have been cut for lights, pipes and wires, and whether the house will need a fan for fresh air once it's tighter. The schedule turns on the same things, plus anything that has to be fixed first, like a roof leak or wet insulation. If the insulation itself is thin, we can top up your attic insulation right after the sealing, and your estimate is written out step by step so you can see what goes where.
I come out to look at every job and write the estimate myself. Our installers do the work with me or a lead installer on site, so the person who found the leaks is the one making sure each of them gets sealed.
I was an HVAC service tech before I started this business in 2023. Working on equipment in attics and crawl spaces, I kept finding that the leaks and thin insulation around it were the bigger problem, so I know where to look.
We're licensed and fully insured. Air sealing puts our installers in your attic among wiring, ducts and fans and over your ceilings, so that cover protects you as much as it protects us, and you're welcome to ask about it.
If your attic is already tight and the trouble is somewhere else, I'll say so rather than sell you sealing your house won't use. Satisfaction guaranteed. Call (843) 278-0240 or use the form below to set up a visit.
We reply to every call and form within one business day and set a time to come look at the attic and crawl space, and the estimate is free, done on site, with no pressure and no obligation. When you reach us, mention how you get into the attic and whether you have a roof leak, a kerosene heater or a gas fireplace, since those change what we check first.
In North Charleston, the city's Building Department issues building permits for renovations and residential projects, and the city requires the proper permits before anyone alters a structure. Doing that work without them is a misdemeanor under the city's rules, so we don't guess. We find out which office covers your address, check what it asks for and take care of any permit your job needs before we start. The state also counts a contractor you hire for specialized trade work over $500 as a residential specialty contractor, which is worth keeping in mind when you compare crews.
Most of our calls come from older houses, where years of new wiring, plumbing and lights have left holes in the attic floor that nobody went back to close. 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. If cost is what's holding you back, Palmetto Community Action Partnership in Charleston runs a weatherization program that can include air sealing, weather stripping and caulking, and insulation of attics, walls and floors.
There's no set price, because the cost depends on how many leaks are hiding in your house and how hard they are to reach. Deep or old insulation that has to be moved, a tight attic opening, a lot of can lights and pipe holes, or a fan for fresh air all add to it, while an open attic with few holes keeps it down. Your estimate lays out each step, so you can see what you'd be paying for.
Yes, for the obvious gaps, like around door frames, where caulk or new weather stripping usually does the trick. What you'll miss are the small leaks in the attic hidden under the insulation, and those are the ones that take testing tools to find. That hidden part is usually what we're called in for.
Certified home energy assessors find them with a blower door test, a big fan that pulls air through the house, and thermal camera images that show where it's coming in. If you're comparing crews, ask whether they hold either of the two nationally recognized certifications, BPI Building Analyst or RESNET HERS Rater. You can also look for insulation that has turned black, since that's a sign air has been moving through it, and point those spots out when someone comes to look.
It can, because a tighter house can trap pollutants like carbon monoxide, radon and volatile organic compounds, the fumes some household products give off. The fix may mean adding ventilation fans or repairing whatever is giving off the pollutant. Ask whoever seals your house to check how well it's ventilated, which also guards against a buildup of damaging water vapor, and that's the same fresh-air check we do before we finish.
Have the attic inspected before any sealing starts. A federal guide to attic air sealing calls for checking for active knob and tube wiring, vermiculite insulation, leaking roofs, bath fans vented into the attic, unvented kerosene heaters or gas fireplaces, and attic flooring. Any of those can change what gets sealed and in what order, so clear a path to the attic hatch and tell us about any you already know of.
