Summerville houses usually bring us one of two calls. Older homes near downtown tend to sit up on crawl spaces where the insulation under the floor is thin, sagging or gone, so people tell us about cold floors in winter and a musty smell in summer. In the newer neighborhoods the ductwork often runs through the attic, and that's where the hot upstairs bedroom and the high power bill come from.
In either kind of house, I start with what's already there. That means how many inches are up there, whether it's dry, and where air is getting through. In this humid weather, a damp crawl space or a buried eave vent can show up as moisture in the framing long before you notice anything inside, so we fix that first and insulate after.
Send the form or call (843) 278-0240, and we'll reply within one business day to set a time. I come out to your Summerville house myself, look over the attic or crawl space, and write a free estimate step by step so you can see what goes where. There's no pressure and no obligation.
(843) 278-0240In Summerville attics we seal the gaps around can lights, pipes and the hatch, then add blown-in insulation, which is loose fill blown in through a hose, evenly out to the eaves. Under older raised houses we handle crawl space insulation and vapor barriers to keep the floor warm and the ground damp out. Where the ductwork lives in the attic, spray foam is often the better fit. When old insulation is soaked or full of droppings, we take it out before anything new goes in.
The first thing I check on a Summerville job is whether your address is inside the Town of Summerville or in unincorporated Dorchester, Charleston or Berkeley County, because that decides whose rules apply. Inside Summerville's limits, the Building Department requires permits and inspections for renovations and for repairs to a house's structure and systems. When a job goes through plan review there, it usually takes about three weeks, and workload or weather can stretch that. We check what your job calls for and take care of any permit before we start, so if one's needed, the review can set the start date more than the attic does. Before you hire anyone, ask to see their South Carolina contractor license for the work and a current Summerville business license. The price moves with the size of the space, how easy it is to reach, and whether old insulation has to come out, and my estimate lays out each part.
Summerville is a straight run up I-26 from North Charleston, so getting out to look at your house is no harder than a job in our own city. We do the same attic and crawl space work next door in Ladson and over in Goose Creek. Because of that, we usually have a fair idea what's waiting before the hatch comes open, though I don't write anything down until I've seen it. If you're just outside Summerville and don't see your city on our list, call and ask.
Our installers work with me or a lead installer on site, so someone who knows the plan is there to check that every gap is sealed before anything gets covered up. We're licensed and fully insured, and the person who wrote your estimate is a phone call away.
I spent years as an HVAC tech crawling through attics before starting this business in 2023, and the real trouble was usually the leaks and thin spots around the equipment. We seal and dry things out first. If a job can wait, I'll tell you so.
Foam costs more, and it seals air while it insulates, which pays off when your ductwork runs through the attic. In most other attics, sealing the gaps and topping up loose fill usually does the job, so that's what we'll recommend. Satisfaction guaranteed. Call (843) 278-0240 to set up a visit.
There's no set price, because it depends on what I find, and I put the figure in writing after I've seen your attic. The biggest swings come from how many inches are already up there, how tight the access is, and whether old insulation is wet or full of droppings, because that has to come out first. Choosing foam over loose fill raises it too.
We ask the Building Department before we start, because its permit list doesn't settle the question for insulation on its own. Inside Summerville's limits, permits cover renovations, repairs to a house's structure and systems, and mechanical, roofing and vinyl siding work, so if your insulation is part of a reroof, new siding or HVAC changes, that work has its own permit. If your job needs a permit, we take care of it.
Yes, Summerville requires a yearly business license from businesses outside its limits that do work there, not only from businesses based in Summerville. Licenses run from May 1 to April 30, so it's fair to ask any contractor, us included, whether theirs is current.
With blown-in insulation you can usually stay home the whole time, and I give you the crew's time on site when I write the estimate, because it depends on the attic's size and how much sealing comes first. Spray foam has a re-entry time, a wait before people and pets can come back in. We plan the day around it and tell you that time before we start.
Usually it's the crawl space, where insulation has fallen down, gotten damp or was thin to begin with, and outside air moves freely under the house. We check for moisture first and put down a vapor barrier where it's needed, because new insulation over a wet crawl space just holds the water against the floor.
Most often it's warm attic air getting in through gaps around can lights, pipes and the attic hatch, along with insulation that's deep in the middle and thin at the edges. We seal those gaps first, a step called air sealing, and then even out the coverage to the eaves without burying the vents, because a blocked eave vent traps moisture in the framing.
