Homes old and new across Summerville

Summerville is a short drive from us, and we work there the same way we do in Goose Creek and up in Moncks Corner. Early on every Summerville job, we settle whether the house is inside town limits or in unincorporated Dorchester, Charleston or Berkeley County, a question the Town of Summerville's planning page puts up front, because the town's building rules apply inside its limits.

On our jobs there, we mostly see two kinds of houses. Near downtown, a lot of homes are older, many sit on raised crawl spaces where Lowcountry damp comes up from the ground, and the attic holds whatever went in decades ago. Out in the newer neighborhoods, the air handler and ductwork often sit up in the attic, and the room over the garage is usually the one people call about. That split tells me where to start, under the floor in an older house and up top in a newer one, before any new insulation goes in.

Our services in Summerville, SC

  • Many Summerville attics hold a thin layer that settled years ago, so upstairs bakes all summer. We measure what's up there and build it back up, full at the edges with the eave vents left open.

  • Can lights, pipe holes and loose attic hatches let damp Summerville air into the house, and insulation laid over them just fights the draft. Our air sealing services close those gaps first.

  • Rooms over the garage in newer Summerville homes run hot because their walls and ceilings are tight and hard to reach. Foam fills those spaces and seals the air leaks in the same pass.

  • Some Summerville attics hold insulation soaked by an old roof leak or full of droppings, and new material on top just buries that. We pull the old layer out first.

  • Older houses near downtown often sit on crawl spaces where Lowcountry humidity rises out of the dirt and into the floor framing. We lay a vapor barrier over the ground so that damp stays down there.

  • Some of Summerville's older homes were built with little or nothing in the exterior walls, which is why those rooms feel drafty in winter. We can usually fill closed walls without tearing them open.

How it goes when you call us about a Summerville house

  1. Call or send a request

    You call (843) 278-0353 or fill in the form, and we set a time to come out to your Summerville house. Tell us what's bothering you, like a hot room over the garage or cold floors, so I know where to look first.

  2. Walk the house with me

    I come out myself and go up in the attic or under the crawl space with you, showing you the inches already up there and any wet spots, gaps or buried vents I find. It helps if you're home for this, so you see it for yourself instead of taking my word for it.

  3. Go over the written plan

    You get a written estimate that says what we'd fix first, what comes after and why, and we go over it until the plan makes sense to you. We also check with the office that covers your address and take care of any permit the job calls for, and in town most plan reviews take about three weeks, longer when the office is busy or the weather's bad.

  4. Do the work, then walk through

    On the day, our installers protect your home and do the work in the order we agreed, and I'm usually right there with them. If the job needs an inspection, the town can usually get to it by the end of the next business day when we ask by 3 p.m., and before we leave I walk you through the finished space.

Summerville insulation questions

How much does it cost to insulate an attic in Summerville?

The price comes down to how big your attic is, how many inches are already up there and what has to be fixed before anything new goes in. Pulling out soaked or dirty old insulation, sealing gaps and choosing foam over blown-in all raise it, while a clean attic that only needs topping up keeps it lower. I'll put your own number in writing after I've been up there.

Do I need a permit to insulate my house in Summerville?

The town's permit list doesn't name insulation either way, so we check with the office that covers your address before we start and take care of any permit the job calls for. Inside town limits, the town's Building Department requires permits and inspections for renovations and repairs to building structures and systems, and for roofing, vinyl siding and electrical, gas, mechanical and plumbing work.

Does an insulation contractor from Hanahan need a Summerville business license?

Yes, the town requires an annual business license from businesses outside town limits that do work in town, not only from businesses based there. The license runs one year, from May 1 to April 30, so it's fair to ask any contractor whether theirs is current.

How do I know if an insulation contractor is licensed in South Carolina?

Ask to see their state license or registration, because South Carolina requires contractors and subcontractors to be licensed for the work they do. Residential mechanical trades need a specialty license that takes an exam, other trades need a registration, and either one is required once a residential specialty job is worth more than five hundred dollars. We're fully licensed and insured, and I'm happy to show you.

What is the best way to insulate an attic in Summerville?

For most Summerville attics, sealing the gaps and then topping up with blown-in insulation, which is loose fill blown through a hose, gives you the most for your money. Foam costs more because it seals air and insulates in one step, and it usually earns that cost when the ductwork and air handler live up in the attic, which we see a lot in the newer neighborhoods. I'll tell you straight if foam isn't worth it for your house.

Do I need a permit if I insulate my own attic in Summerville?

Not always, because South Carolina exempts certain improvements an owner makes to their own home from building permit and licensing rules. That list is grouped into building, electrical, gas, mechanical and plumbing work, so check with the town's Building Department whether your attic job is on it before you start.
