Hanahan sits at the south end of Berkeley County, right where it meets the Charleston County line, so it's close to home for us. The calls we get here are the familiar ones: a hot upstairs, a drafty room over the garage, cold floors over the crawl space and a power bill that keeps creeping up.
Several neighborhoods here have tidal water behind them, so on those houses I look hard at the crawl space before I talk about anything else. Damp under a house has to be dealt with first, because insulation laid over it just hides the problem until it shows up in the framing.
We reply to every call and form within one business day. I'll set a time to come out to your Hanahan house, look at the attic or crawl space myself and write up the estimate. There's no pressure and no obligation to go ahead.
(843) 278-0240Most of the work we do here starts in the attic, where we close the gaps around lights, pipes and the hatch before we blow in loose fill to an even depth, edges included. Under the house we insulate crawl spaces and lay vapor barrier where the ground stays damp, and we pull out old insulation that's been soaked or fouled before anything new goes in. Where the ductwork runs through the attic, spray foam can earn its higher price. If you're not sure where your house is losing heat, our home insulation page walks through the whole house, top to bottom.
South Carolina leaves each city and county to enforce the building codes for itself, and code questions about a property go to the local building official for that jurisdiction. Hanahan's city limits run along the county line, so I find out which city or county office covers your address, check what it asks for and take care of any permit the job needs, and when one is needed, it comes before the work does. The state's list of improvements an owner can make to their own house without a permit covers things like fences, driveways and painting, not insulation, so we don't treat an insulation job as exempt. On the contractor side, the state's Residential Builders Commission licenses or registers residential builders and specialty contractors, and specialty work over $500 needs one or the other, so it's fair to ask anyone you're weighing. We're licensed and fully insured.
On the job itself, the price moves with the size of the space, how many inches are already up there, whether old material has to come out first and which material your house needs. The schedule turns on that same removal, on any permit and, with foam, on the wait before you can go back inside, and the estimate gives you your own figure. We do this same work across the cities around us, including Goose Creek and Mount Pleasant.
I look at every job myself, measure what's already in the attic or crawl space and write the estimate out step by step, so you can see what goes where. If something can wait, I'll tell you that too, rather than sell you work your house won't use.
If what's up there has been soaked or is full of droppings, laying fresh material on top keeps the problem in your attic. We find the cause, pull out what's spoiled and fix the damp first, so the new insulation goes onto something clean and dry.
I spent years servicing heating and air equipment in attics and crawl spaces before starting this business in 2023, so I check the ducts while I'm up there. Our installers work with me or a lead installer on site. Call (843) 278-0240 to set up a visit.
I can't give you an honest number until I've been in your attic, because the cost follows the work your attic needs. A tight hatch, a low roof or lots of can lights and pipes to seal around add time, and closed-cell foam costs more than loose fill. Call (843) 278-0240 or send the form, and the free estimate will show your figure.
Usually it's air moving through gaps the insulation never covered, around can lights, pipes, wires and the attic hatch. Thin coverage at the edges and buried eave vents make it worse, because heat comes straight through the edges and the attic can't breathe. We seal those gaps first, then even out the insulation so it isn't deep in the middle and thin at the sides.
For most older houses, sealing the gaps and topping up blown-in insulation, loose fill blown in through a hose, does the job for less. Foam costs more but seals air while it insulates, so it starts to make sense when your ductwork runs through the attic. I'll tell you which one your house needs and why once I've been up there.
Yes, with spray foam you, your kids and your pets stay out until the re-entry time is up, which is the wait the foam maker sets before people can come back in. With blown-in insulation and air sealing you can usually stay home. We go over the timing for your job before we set a start date.
Search your street address on Berkeley County's FEMA flood map or the SCDNR Floodplain Map Viewer, and either one will show your flood zone. The county map shows flood data only, and where preliminary maps exist, the state viewer lets you switch between those and the current ones. Tell me what you find when you call, because it changes how I look at your crawl space and what we'd put under the house.
