How do you insulate the walls of an existing house in Goose Creek?
Wall insulation for an existing Goose Creek house means filling the empty spaces inside your outside walls, usually through small holes, without pulling the drywall, so your rooms hold the temperature you set. It often goes with sealing air leaks first. It can also go with new siding, which is the easiest time to do the work from outside.
Older houses often went up with little or nothing in the outside walls, and adding it later means working around finished drywall and siding you want to keep. The price turns on how much wall area we're filling, whether we work from inside or outside, and what has to be fixed or sealed first. Sometimes a thin attic is the bigger problem, and if so I'll tell you that attic insulation should come first. The schedule mostly depends on how easy the walls are to reach and whether siding work is coming. Your written estimate lists each area, material and prep step, so you can see the figure for your own house.
How can you tell your walls need insulation?
One side runs hot
If the rooms on the sunny side of the house stay warm long after the AC kicks on, the outside walls there are usually empty, or the old insulation has slumped toward the bottom. Waiting means the system works harder every summer, and your power bill shows it.
Walls cold to the touch
In winter, an outside wall that feels much colder than an inside one is usually letting heat pass straight through. Leaving it means drafty rooms and a heat pump that runs longer than it should.
Drafts at outlets and switches
Air you can feel at an outlet cover on an outside wall means the cavity behind it is open to the outdoors somewhere. Insulation alone won't stop that, so those gaps need sealing before the walls get filled, or the new fill ends up fighting a draft.

Air sealing services
Leaks carry heat around insulation instead of through it, so closing them before we fill means the new material slows heat instead of letting it slip past.
Basement insulation
Walls below ground sit against damp soil and need a different approach than framed walls above it, so we quote and insulate them as their own job.
How we handle wall insulation on your house
I start by looking at what's in a few of your wall cavities now, whether that's nothing, old insulation that has slumped or wiring we have to work around, and I note anything that should be fixed first. Then we work out with you whether to fill from inside or outside. If new siding is on the way, I'll suggest doing the walls at the same time so the wall only gets opened once. For inside work, our crew covers your floors and sets up dust containment before anyone drills. Before we start, we talk through how the holes get finished, either patched or hidden behind chair rail molding. In a house built before 1980, lead safety rules can apply depending on how much the walls get disturbed, so I bring that up before any wall is opened.
Gaps come before fill, so we often pair wall work with air sealing services around outlets, window trim and the tops of the walls, because insulation packed into a cavity that still leaks air won't do its job. If the wall you're worried about is below ground, that's basement insulation, a separate job we'll look at on its own.
Filling from inside
This suits a house whose siding is sound and staying put, because the outside of the wall is left alone. It does mean small holes in your drywall, which get patched or covered once the cavities are full.
Filling from outside
This fits when you'd rather keep the drilling out of your finished rooms and the siding lifts off and goes back on cleanly. Any repair to what's behind the siding is listed on the estimate.
Along with new siding
If you're re-siding anyway, this is the best time to insulate from outside, because the house wrap is exposed and can be checked and reinstalled if it needs it. It's also the one point where rigid foam board can go over the outside of the wall, either with the cavity fill or instead of it.
Open walls during a remodel
When the drywall is already off, batts, which are pre-cut blankets of insulation, can be very cost effective if the stud spaces are an even, standard size. Each batt has to be cut to fit snug around wires, pipes and boxes without being squashed, because a crushed or gappy batt leaves cold spots.

The estimate comes from me
I come out myself to look at your walls, measure and write the estimate. I started out writing up insulation jobs before I learned to install them, so I write it so you can follow what's going in, where it goes and why.
In business since 2020
We've been running our own jobs for six years, and I learned the trade on install crews before that. That time is why I'll tell you plainly when something should wait or isn't needed.
Licensed and fully insured
We're licensed and fully insured. South Carolina lists insulation installers among its residential specialty contractor trades when a job for a homeowner runs over $500, so it's fair to ask any contractor about their status with the state licensing board.
Problems first, then gaps, then fill
Anything that needs fixing gets handled first, gaps get sealed next, and the insulation goes in last. I'd rather quote what your walls need than what sounds good, so your money goes where it counts.
The decision that matters most on walls is which side we work from, and that's easiest to settle standing in your house, so contact us and I'll come take a look.

Common questions
How do I insulate existing walls without tearing them out?
You have them drilled and filled, which means small holes near the top of each wall cavity, the space between two studs, and blown-in insulation, loose fill sent through a hose, packed into the space. It's one of the less disruptive ways to insulate a finished house because the drywall and siding stay up, and the holes can be made from inside or outside.
What is the best way to fill walls, from inside or outside?
If your siding is in good shape and staying, filling from inside is usually the better choice because it leaves the house wrap untouched. Drilling from outside cuts through the house wrap, the layer behind the siding that sheds water, so it has to be patched or replaced afterward. That makes outside work the better fit when the siding is coming off anyway.
How much does wall insulation cost in Goose Creek?
Installed blown-in wall insulation across the US usually costs about $4 to $4.50 per square foot of wall, so treat that as a national ballpark rather than our price. Your own cost depends on the wall area, which side we work from and any repairs or sealing that come first. Your written estimate lists each of those so you can see the figure for your house.
Who do I call about permits for wall insulation in Goose Creek?
The city's Permits Division handles permitting for Goose Creek, and you can reach it at (843) 797-6220, ext. 1100 or 1122. Before we schedule, we check with the office that handles permits for your address, since that can differ depending on where you live. If a permit is needed, we take care of it and let you know where it stands.
Should I put a plastic vapor barrier on the inside of my walls?
Usually not. Guidance for warm, humid climates keeps plastic sheeting and other Class I vapor retarders, which stop moisture almost completely, off the inside of walls filled with insulation that air passes through, except behind a shower or tub. Water that condenses on that layer has no way to dry toward the room, and over time it can ruin the insulation and lead to mold and rotted framing.
Can you blow insulation into walls with knob-and-tube wiring?
No. The National Electrical Code bars insulation from being applied to or around knob-and-tube wiring, the old cloth-wrapped wiring strung on porcelain knobs. If I find it when I measure, those walls wait until the wiring has been dealt with, and I'll tell you which walls are clear to fill now.
