Insulation Contractor in North Charleston - Cooler Upstairs, Drier Crawl Spaces

The price mostly comes down to how many inches are already up there, whether the old material has to come out first and how much air sealing the attic needs. Foam costs more than blown-in, which is loose fill we blow through a hose, and a tight attic or ductwork in the way adds time. After I look at your attic, the written estimate shows what you'd be paying for and why.

The state Residential Builders Commission licenses or registers residential builders and residential specialty contractors who work on houses up to three floors high. Its builder definition covers anyone who builds, repairs or improves a house, or offers to, once the job costs more than five thousand dollars, and commercial buildings fall under separate licensing. We're fully licensed and insured, and you're welcome to ask me about it at the estimate.

Houses in North Charleston fall under the statewide building codes adopted by the South Carolina Building Codes Council, and the 2021 codes took effect January 1, 2023. The council has since published a round of changes, and some changes it allows apply only in named local areas once a local law puts them in place. That's why it's worth asking any contractor how they keep up with what applies to your house.

Usually not for the whole house, unless your ductwork runs through the attic. Foam costs more and seals air while it insulates, which pays off when ducts sit up in that heat or the room over the garage won't cool. For most other attics, sealing the gaps and topping up loose fill does the job for less, and I'll tell you straight out which one your house needs.

Air sealing and a loose-fill top-up is usually a short job, and you can stay home while we work. Spray foam is different, because you, the kids and the pets have to stay out until the foam maker's re-entry time, how long before it's safe to come back, has passed. I'll tell you at the estimate how long your job should run and when you can go back in.

Mostly humid outside air working its way under the house and settling on the cooler floor framing and ducts, made worse when the plastic ground cover is torn or missing. Insulation sagging down from the floor is a common sign you'll spot with a flashlight. We pull out what's soaked, lay a sealed vapor barrier and insulate once it's dry.
