Air sealing services in Summerville SC - rooms that hold their temperature
Drafty rooms or a hot upstairs usually mean air is leaking in. We find where it's moving and seal it so the rooms stay comfortable.
I do every estimate visit myself
I do every estimate visit myself, and I go up into the attic and under the house instead of guessing from the driveway. You get a straight answer from the person running the job, even when it's that you don't need much.
Six years of doing the prep first
We've been in business since 2020, and the thing we're known for is the unglamorous prep done before anything you can see. On an air sealing job, the leaks and anything that has to be fixed get found before a single gap is sealed.

What air sealing fixes in a Summerville house
Air sealing services in Summerville close the gaps where air leaks through your attic, walls and the openings around pipes, lights and the attic hatch. It helps anyone with drafty rooms, a hot upstairs or a room over the garage that never feels right.
Those leaks do more than make a room drafty. Conditioned air slips out, your heating and cooling equipment works harder to keep up and the power bill climbs, and the same gaps can let in moisture that can warp wood and lead to mold. The price mostly comes down to how many leaks there are, how hard they are to reach in a low or floored attic, and whether something has to be fixed before we seal.
The schedule turns on the same things, since anything that needs another trade gets fixed first, and your estimate lays out the plan and order in writing. Summerville's Building Department requires permits for renovations and repairs to building structures and systems, and its list names roofing and vinyl siding, not air sealing, so that's the office to ask. We sort out which office covers your address and handle any permit the job needs.
How our air sealing services work
We find the leaks first
We find the leaks before we seal anything, so the work goes where air is really moving and not just where it's easy to reach. The worst gaps in an attic are usually the ones nobody wants to crawl to, around can lights, plumbing and wiring holes, the attic hatch and the tops of interior walls out near the eaves. Some sit under the old insulation, so it has to be pulled back to reach them. Seal the easy spots and skip those, and the draft stays right where it was.
Check the attic before sealing
A federal attic guide says to inspect the work area before any air sealing starts, and that matches how I like to begin. We look for old knob and tube wiring, bathroom fans that vent into the attic instead of outside, a leaking roof, an unvented kerosene heater or gas fireplace, and attic flooring that hides gaps. Some of that belongs to another trade, and Summerville requires permits and inspections for electrical, gas, mechanical and plumbing work, so it gets fixed properly before we seal over it.
The right seal for each gap
Foam costs more, and it seals air while it insulates. In most attics, sealing the gaps and then topping up the loose fill usually wins, because the sealing stops the air and the fill handles the heat for less money. That changes when your ductwork runs through the attic, and then spray foam such as closed-cell foam insulation, the dense kind that also blocks moisture, can earn its price. If your house has a basement, the rim along the top of its walls is a common leak, so it's worth sealing when you plan basement insulation.

I inspect and write it up
I come out myself and look at the attic, crawl space or walls, checking for anything that has to be fixed first. At the visit I tell you what I'd do and in what order, then you get it in writing.
Our installers seal, I check
Our installers do the sealing in the order we agreed, after any fixes that had to come first. Before we call the job done, I look the work over myself, so you aren't left guessing what got sealed.
Air sealing questions from Summerville homeowners
Do I need air sealing if my attic already has insulation?
Often, yes, because insulation slows heat moving through a ceiling or wall, but it may not stop air from moving through the gaps around it. If rooms still feel drafty with a decent depth already up there, leaks are the usual reason. I'll tell you at the visit if your house doesn't need much.
How do contractors find air leaks in a Summerville home?
Professionals can use a blower door test, where a fan set in an outside door pulls air out of the house so leaks show, and a thermal camera that picks out the spots where air gets in. It's worth asking whether a job starts with that kind of testing, so the sealing targets the leaks it actually finds.
Should air sealing come before new attic insulation?
Yes, the sealing goes first. Federal energy guidance has air sealing finished before insulating, and on an existing vented attic the first step is sealing every opening through the attic floor, with sealant, spray foam or rigid board as needed. If you're adding insulation, schedule the sealing first, because new insulation buries those gaps.
What should I do if my attic has vermiculite insulation?
Have it tested before anyone air seals or insulates the attic, because vermiculite may contain asbestos. Federal guidance also calls for professional advice and contacting your state Department of Health. If I spot it at the visit, we leave it alone and plan the job around the test results.
