Services in Sangaree, SC
Attic insulation
Many Sangaree attics still hold the fill from when the house was built, and it has settled thin. We top it up evenly, with the edges as deep as the middle.
Attic air sealing
Upstairs drafts in Sangaree homes usually come through gaps around can lights, pipes and the attic hatch. We seal those first, so new insulation isn't fighting moving air.
Crawl space vapor barrier
Sangaree homes on crawl spaces can pull damp air from bare ground into the floors. We lay a vapor barrier, a sealed plastic sheet, across the dirt.
Insulation removal
Attic fill in a house that's been lived in for years sometimes gets soaked by leaks or fouled by rodents. We pull it out before adding anything.
Basement insulation
Few Sangaree homes have a basement, but a below-grade room stays damp. Our basement insulation covers those walls in closed-cell foam, the dense kind that blocks moisture.
Spray foam insulation
A room over the garage often runs hottest in Sangaree homes, since its floor and side walls border the garage and attic. We seal them with spray foam.
Sangaree, SC properties and local conditions
When I climb into an attic in Sangaree, the first thing I measure is how many inches are already up there, because most of these houses have been lived in a while and the original blown-in fill, loose insulation blown through a hose, has usually settled. It's often deep in the middle and thin along the edges, where it does the least good, and sometimes it has been pushed over the eave vents, so the attic can't breathe and moisture starts to show on the framing. We pull it back off the vents, set baffles, which are chutes that hold the airflow open, and level the new layer so the edges get their full share.
Under the floor is the other place we look closely. Flooding and hurricanes are a real hazard across South Carolina, and a crawl space usually shows it first, with damp soil, sagging batts or a water line on the piers. I'd much rather find that before we insulate than after, so we deal with the water and the ground cover first and then choose a material that suits what we found.
What to know about permits and licenses in Sangaree
Sangaree is run as a special tax district whose volunteer commissioners advise the Berkeley County Council on local services, so permits for your address come from the Berkeley County Permitting Department. Before work starts we ask that office whether your job needs a permit, and if it does, we handle the application and keep you informed, which means your start date waits on the county's answer. The county only issues permit authorization to someone who shows a current South Carolina State Contractors License Card, the wallet card rather than the wall certificate, and you can look up any contractor, us included, with the South Carolina Residential Builders Commission, which licenses residential specialty contractors for homes up to three floors. We're fully licensed and insured, and on our side the price mostly follows the size of the spaces, how easy they are to reach and how much insulation is already in place.
We're based in Mount Pleasant and work in the cities around it, and Sangaree sits right alongside Summerville and Goose Creek, where we see the same kinds of subdivision homes. Most houses here sit on quiet residential streets with the attic hatch in a hallway or garage ceiling, so at the estimate I plan where the truck parks, how the hose reaches the hatch and which floors we cover.

Call or send the form
Reach us at (843) 416-5007 or through the form, and we'll set a visit at a time that suits you. Someone needs to be home so I can get into the attic and crawl space.
I look over the house
I check for old wiring, water, rodents and fuel-burning appliances, and I measure what's already up there. Then I walk you through what I'd do and why, and give you a price for that work.
We prepare and do the work
Once the county's answer on permits is in, our crew covers floors and the path to the hatch before any insulation comes out. For spray foam, we'll tell you ahead of time when the house needs to be empty.
We walk through it together
Before we leave, I go over the finished job with you, in the attic if you'd like to look, so you understand what we did and why. Every job is backed by our satisfaction guarantee.
Frequently asked questions
Which building codes apply to insulation work in Sangaree, SC right now?
The 2021 South Carolina Building Codes apply today, and they've been in effect since January 1, 2023. The state's building codes council lists January 1, 2027 as the date the 2024 codes take effect, which is only a couple of months away. We work to whichever edition is in effect when your job is done.
How do I find out if my Sangaree home is in a flood zone?
You can look up your address on Berkeley County's FEMA flood map, which has a print tool if you want a copy. That map carries FEMA flood data only, so for property lines and parcel details you'd use the county's Advanced Desktop Map instead. If you're in or near a flood zone, please tell me at the estimate, because it changes what I'd suggest for the crawl space.
What is the best way to insulate a crawl space in Sangaree?
Deal with the moisture first, then insulate. In most crawl spaces that means a vapor barrier over the ground, then insulation on the floor above or on the crawl space walls, depending on how it's vented and whether ducts run down there. Where a crawl space has seen water, closed-cell foam usually makes more sense than batts, since it doesn't soak water up.
How much does insulation cost for a house in Sangaree, SC?
I can't give you a fair number until I've seen your attic or crawl space, because two houses the same size can need very different work. The biggest swings come from whether old, soaked or dirty insulation has to come out first, how many gaps need sealing and whether you choose foam or loose fill. Foam costs more and seals air while it insulates, but for most attics I'd seal the gaps and top up the loose fill, unless your ductwork runs up there, where foam usually earns its price.
Should old attic insulation be removed before adding new insulation?
Only when it's wet, moldy or full of droppings, because new material laid over it keeps the problem in your attic. Dry insulation that has simply settled can usually stay, and we add to it. I'll show you what I find so you can see why I'm suggesting one or the other.
When can kids and pets come back inside after spray foam insulation?
After the re-entry time, the wait the foam maker sets before people and pets go back in, which I'll give you for the exact product before the day. Plan to have everyone, pets included, out of the house while we spray and through that wait. Blown-in work doesn't usually require you to leave, though we'll ask you to keep children and pets away from the hatch.
About Sangaree, SC
Sangaree is a residential community in Berkeley County, made up mostly of single-family subdivisions such as Victoria Place and Hampton Trace, and it shares a border and a lot of its character with neighbors like Ladson and Summerville. The homes are lived-in family houses rather than new construction, many with a two-story layout, a room over the garage or a crawl space underneath, and the same handful of comfort complaints comes up from street to street.
Because these houses have had years of living in them, the attic and crawl space usually tell a story before we add anything, whether that's an old leak, a hatch nobody sealed or fill that settled long ago. That's why I start every Sangaree estimate by looking at what's already there.
