Most calls we get from Sangaree are about a hot upstairs, a drafty room over the garage or a power bill that keeps creeping up. When I climb into those attics, the usual story is loose fill that's settled thin and air finding its way up through gaps nobody sealed. I spent years as an HVAC tech in attics like these, so I look hard at the ductwork too, because when it runs up there it changes what the job should be.
Sangaree is a short drive up from North Charleston, and the houses here have a lot in common with what we see in nearby Summerville. Under the house, I check the crawl space for damp soil or old insulation hanging loose before I'll suggest putting anything new down there.
We reply to every call and form within one business day and set a time for me to come out to your Sangaree house. I look over your attic or crawl space and write the estimate on site. It's free, with no pressure and no obligation.
(843) 278-0240Most Sangaree jobs start in the attic, where we seal the gaps around lights, pipes and the hatch and then top up the blown-in insulation, loose fill blown in through a hose, so it's even all the way out to the eaves. We pull out soaked or droppings-filled insulation before anything new goes in, and we put vapor barriers and insulation in crawl spaces once they're dry. We use spray foam where the ductwork lives in the attic, and we handle basement insulation on the occasional house with a below-grade room.
Sangaree runs as a special tax district under Berkeley County rather than as its own city, so any permit for work here goes through the Berkeley County Permitting Department. Before we set a start date, I check what the county asks for at your address and take care of any permit your job needs, so that step comes first on the schedule. The county won't authorize anyone to pull permits without a current South Carolina State Contractors License Card, the card itself and not the certificate on the wall, so ask whoever you hire to show you theirs. If you'd rather ask the county about your job yourself, the department's number is 843-719-4292.
Price turns on how big your attic is, how easy it is to move around in, how many inches are already up there and whether old material has to come out first. Sealing a lot of gaps or choosing foam over loose fill adds to it, and the schedule mostly hangs on the permit check and any removal. You'll see your own number on the estimate, and it's the same way we plan jobs in Moncks Corner and Goose Creek.
I come out to every job myself, climb into the attic or crawl space and write the estimate. When the work starts, our installers do it with me or a lead installer on site, so someone who knows the plan is always close at hand.
Years as an HVAC service tech showed me that thin insulation and air leaks around the equipment were the bigger problem. That's why we seal gaps and clear out damp or soiled material first, because insulation laid over a leak or a wet spot only hides it.
Your estimate is written out step by step, so you can see what goes where and why it's there. If your house won't use a piece of work, or it can wait a few years, I'll tell you that instead of selling it to you.
We started this business in 2023, and we're licensed and fully insured on every job. Satisfaction guaranteed. When you're ready, call (843) 278-0240 or send the form, and we'll set a time for me to come out and take a look.
I can't give you a fair number until I've been up in your attic, because the price comes from what's there and not the square footage alone. Removing old material and sealing a lot of gaps usually move it the most. Foam costs more because it seals air while it insulates, and in most attics sealing the gaps and topping up loose fill does the job for less, unless your ductwork runs up there.
It depends on what has to happen before new insulation goes in, so I give you the plan at the estimate rather than guess on the phone. Pulling out old material and sealing gaps takes longer than a top-up, and you can usually stay home while we blow in loose fill. Spray foam is different, because the foam maker sets the re-entry time, how long before people and pets can come back inside, and we tell you that ahead of the day.
Usually it's air leaking through gaps the insulation was laid over, not a shortage of insulation. Openings around can lights, pipes and the attic hatch let air move straight through, and fill that's deep in the middle but thin at the edges leaves the outside walls exposed. We seal first, then even out the depth, and we keep the eave vents clear so the attic can still breathe.
Look them up with the South Carolina Residential Builders Commission, which licenses or registers people qualified for residential building and residential specialty contracting. Its work covers houses up to three floors and apartment buildings with no more than sixteen units in a building. We're licensed and fully insured, and I'm glad to show you our paperwork at the estimate.
The state building codes in force now took effect January 1, 2023, and a newer set is scheduled to take effect January 1, 2027. If your job is planned close to that date, I check which set applies when I look into what the county asks for at your address.
Have it checked for standing water, damp soil and wet or sagging insulation first, because new insulation over a damp crawl space just hides the problem. I look for all of that at the estimate, and a vapor barrier usually goes down before any insulation does. If you want to see whether your lot sits in a mapped flood zone, Berkeley County's GIS has a FEMA flood hazard map you can look up yourself.
