Raised homes and older houses across Hollywood
Hollywood is a small Charleston County city with more room between houses than you'll find closer to Charleston, and a lot of the homes we see there sit up off the ground over a crawl space. There's a mix of older houses that have been added onto over the years, ranch homes from later decades and newer builds, some with a room over the garage that never stays comfortable. It's the same work we do around our home base in Hanahan and out on James Island, just with more houses that have something going on underneath.
That changes where we start. On a raised house the cold floors and the moisture questions usually live in the crawl space, and the hot rooms trace back to thin, uneven attic insulation and unsealed gaps, so I look at both before I recommend anything.
Our services in Hollywood, SC
When ductwork runs through a Hollywood attic, insulation on the attic floor leaves those ducts on the wrong side of it. That's when we spray open-cell foam insulation under the roof deck so the ducts sit inside.
Many houses here sit over a crawl space, and cold floors usually mean the batts underneath have sagged or dropped. We pull what's ruined and insulate the floor from below so it stays put.
Bare dirt under a raised house gives off moisture that soaks into the framing and insulation above. We lay a vapor barrier, a heavy plastic sheet, over the ground and seal the seams.
Older attics here often hold a few settled inches, deep in the middle and thin at the edges, which is backward. We even it out and keep the eave vents clear so the attic still breathes.
A hot or drafty upstairs usually has air slipping through gaps around can lights, pipes and the attic hatch. We seal those first so new insulation isn't fighting a draft.
In older homes we sometimes find insulation that's been soaked or is full of droppings, and covering it just keeps the problem. We bag it out and clean up so the new material starts fresh.

What happens after you call us in Hollywood
Call us or send a request
You reach us at (843) 278-0353 or through the form, and we set a time to come out to your house in Hollywood. Tell us what's bothering you, whether it's a hot room, cold floors or the power bill, so I know where to look first.
Look at the house together
I come out myself to look at the attic, crawl space or walls with you and show you what I find, so it helps if you're home. Then 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.
Do the work in order
On the day, our installers protect your home and work in the order the estimate set, and I'm usually right there with them. If the job calls for a permit, we've already checked with the Town of Hollywood and taken care of it before we start.
Walk the finished space
Before we leave, we walk you through the finished attic or crawl space so you can see what was done and where. If a question comes up later, call and I'll explain it again.
Hollywood insulation questions answered
Do I need a permit to insulate my house in Hollywood, SC?
The Town of Hollywood makes that call, and its building permit covers repairs and renovations to a structure, not only new construction. Homeowners and contractors apply the same way, through the town's Permits Portal, and Town Hall answers questions at 843-889-3222. We check with the town for your address before we start and handle any permit the job calls for.
How do I schedule an inspection for permitted work in Hollywood?
Inspections for town permits are done by CC&I Services, Monday through Friday, and you need to request one at least one business day ahead. The request only counts when it's made directly with a staff member. When we're handling the permit for your job, we take care of that request too.
How do I know if my insulation contractor needs a state license in South Carolina?
Contractors doing specialty work on a South Carolina home have to be registered or licensed with the state Residential Builders Commission once the job is worth more than $500. A contractor working in Hollywood also needs a town business license, and the town asks for proof of state licensure, where it applies, along with a contract or invoice for the job. We're fully licensed and insured, and I'm glad to show you that at the estimate.
Can I insulate my own house in Hollywood without a permit?
South Carolina law exempts certain residential improvements from permit and licensing requirements when the owner of the property does the work. The law lists categories such as building, electrical, gas, mechanical and plumbing work, so confirm with the Town of Hollywood that your project fits before you skip the permit.
What building code applies to insulation work in Hollywood, SC?
South Carolina uses statewide building codes, and the current set took effect January 1, 2023. A newer statewide set takes effect January 1, 2027, so if your job lands near that date, we confirm which set applies when we check on the permit.
How much does insulation cost for a house in Hollywood, SC?
We price your job after seeing the house, because the cost turns on how much attic or crawl space we're covering, how many inches are already up there and whether old material has to come out first. Foam costs more because it seals air while it insulates, but sealing the gaps and topping up blown-in fill, loose insulation blown through a hose, usually does the job for less unless your ductwork lives in the attic. Removal and any permit also add time before the work day, and your written estimate spells all of that out.
