Services in Mount Pleasant, SC

Spray foam insulation

Ductwork in the attic is common here, and it leaves upstairs rooms hot. Spray foam insulation on the roof deck seals air as it insulates and shields those ducts.

Attic insulation

Older attics here often have thin, settled insulation that's deep in the middle and bare at the eaves. We level the depth and keep the eave vents clear.

Insulation removal

Insulation soaked by an old roof leak or fouled by animals keeps causing trouble under anything new. We remove it and clean up before we add a thing.

Crawl space vapor barrier

Many raised houses here sit over bare soil that keeps the crawl space damp. We look for standing water first, then lay a vapor barrier over the ground.

Attic air sealing

Can lights, pipe holes and the attic hatch leak air in older houses here. We seal those gaps first so new insulation isn't fighting a draft.

Wall insulation

Older homes near the Old Village often have walls with little or nothing inside. We fill them from inside where we can, leaving the siding alone.

Mount Pleasant, SC properties and local conditions

Most calls we get here start with a hot room upstairs or over the garage. The attic usually explains it, with a few inches of old insulation that has settled over the years, ductwork running through the hottest part of the house and gaps letting air through. Before we add anything, I also look for old wiring, signs of water and any fuel-burning appliance that needs its air supply left open, because covering those with insulation can create a new problem.

The Town of Mount Pleasant describes two kinds of flooding here, local flooding from blocked or undersized drainage and storm surge from tropical storms and hurricanes. Either one can leave water under a raised house, and wet insulation under a floor sags and holds moisture against the framing, so in a crawl space we look for water lines and damp soil before we put anything back up.

What to know before insulation work in Mount Pleasant

Before work starts on a job here, we check with the Town's building office for your address, because its Front Office staff issue trade permits for any work on electrical, gas, mechanical or plumbing systems, and a building permit covers repairs and changes to the house itself. That answer comes first on our schedule, since we don't start until we know whether a permit applies, and if one does, we take care of the application and keep you informed. You can check any contractor the same way the Town does, because every contractor working in the Town needs a Town business license, and the Town verifies contractor licenses through the state licensing board. We're fully licensed and insured, and you're welcome to look us up.

What moves the price is mostly what's already in your house, such as how big the attic or crawl space is, whether old insulation has to come out first, how easy the space is to reach and whether foam or loose fill suits where your ducts run. The schedule turns on the same things, plus the permit check, and at the estimate visit I'll explain what I found and what I'd suggest so you have your own figure. We do the same work in North Charleston and on James Island, where the houses raise many of the same attic and crawl space questions, though the office we check with changes with the address.

How it goes when you call us about a Mount Pleasant home

  1. Call us or send the form

    Tell us a little about the room or the space that's bothering you, whether it's a hot bedroom, cold floors or an attic you aren't sure about. We'll set a time for me to come out.

  2. I look over the house

    I come out myself, go through the attic, crawl space or walls, and ask a few questions about how the house feels through the year. It helps if you're home so I can show you what I find, and you'll hear the price before anything starts.

  3. We check permits and install

    We check with the building office for your address first, and when a trade permit is tied to a master permit, the Town typically issues it the same day. Our install crew then protects your floors and belongings and does the work.

  4. We walk through it together

    Before we call it done, I check the work over with you, in the attic or under the house if you'd like to look. You'll know what we did, where and why before we leave.

Frequently asked questions

Do I need a permit to insulate my attic in Mount Pleasant, SC?

Under the Town's permit rules, a job valued at $1,000 or less in material and labor doesn't need a building permit unless it calls for an inspection, though site plan approval can still apply. Larger jobs, or work that touches wiring, gas lines or ductwork, can need one, which is why we check for your address before any work starts.

Does an insulation contractor need a license in South Carolina?

Yes, state law requires a current South Carolina license or registration for residential building and specialty contracting. Trades such as electricians, plumbers and HVAC contractors show proof of a current state contractor's license before the Town issues their permit, so ask any contractor you're considering for theirs and check it with the state board.

How do I know if my house is in the Mount Pleasant historic district?

The Town's local historic district covers a 37-block area of the Old Village, and if your house is inside it, the Town's historic review board reviews all exterior changes and approves them before work begins. Most insulation goes in from inside, but filling walls through the siding or adding vents changes the outside, so in the district we'd plan for that review before setting a start date.

Which flood rules apply to insulating a crawl space in Mount Pleasant?

The Town's flood maps set the design flood elevation, the height flood rules measure new work against, at two feet above base flood elevation, up from one foot under the old maps. If part of your crawl space sits below that line, we ask the building office for your address what it means for the work before we choose materials.

How much does insulation cost in Mount Pleasant, SC?

The biggest choice in your price is foam or loose fill, because spray foam costs more and seals air while it insulates, while blown-in insulation, loose fill blown through a hose, costs less. For most attics here I'd suggest sealing the gaps and topping up the loose fill, unless your ductwork runs up there, in which case foam usually earns its cost.

How long does it take before we can go back inside after spray foam insulation in Mount Pleasant?

You, your kids and your pets stay out until the foam maker's re-entry time has passed, which is the wait the maker sets before anyone comes back inside, and I'll tell you that time at the estimate for the product we'd use. With blown-in insulation or air sealing alone, most families stay home while the crew works.

About Mount Pleasant, SC

Mount Pleasant is where we're based, and the houses we work in here cover a wide span. Near the harbor, the Old Village has older homes, each with its own story up in the attic and under the floor, while newer neighborhoods farther out are full of two-story houses with bonus rooms over the garage and ductwork running overhead. Plenty of homes in both sit raised over crawl spaces.

We see many of the same house types in Charleston and Summerville, but here the mix of old and new means no two attics look alike, so each job starts with what's already up there and what's under the floor.
