Basement insulation in Fayetteville AR - sealed walls that keep the heat in the house
Cold floors and a chilly basement driving up the power bill? We fix any water first, then seal and insulate the walls.
Is it worth insulating my basement in Fayetteville?
Usually, yes. Basement insulation in Fayetteville lines the inside of your foundation walls with foam so the heat you pay for stops escaping through the concrete, and the basement is where 10% to 30% of a home's heat loss happens.
Most people call me about cold floors over the basement, a basement room nobody wants to sit in, or a damp smell that hangs around after a hard rain. If part of your house sits over a crawl space instead, that side needs crawl space insulation, which is a different job. Your price moves with how much wall there is and which material suits it, and the schedule mostly turns on whether a water problem has to be fixed before we start, so I'll give you your own numbers once I've seen the basement.

What basement insulation looks like
How we do basement insulation, step by step
First I look for water, because we don't insulate a basement wall that's taking on water, and anything that leaks gets sorted out before a single board goes up. Then we air seal the rim joists, the band of framing that sits on top of the foundation, by closing the gaps there before we insulate them, since a lot of basement drafts start right at that spot. After that we line the walls from the inside with foam board or spray foam, seal every seam and gap, and finish by covering the foam, usually with drywall, so it's sealed tight and nothing is left bare.
On a flat, dry wall, sealed foam board is usually the better buy, and on rough or uneven walls spray foam earns its higher cost because it fills every dip in one pass. When we spray, we usually reach for closed-cell foam insulation, a dense foam that holds back moisture, because it stands up to cold concrete. Open-cell foam insulation is softer and lighter, so we keep it for framed walls and rooflines above ground rather than against a foundation.
Why Fayetteville homeowners call us for basement insulation
I look at every basement myself
I come out to every job in Fayetteville and the cities around it across Northwest Arkansas, and I find the real cause of the cold or damp before I quote anything. If insulation won't fix what you're seeing, I'll tell you so instead of selling you a job that won't help.

The crew in your basement is our own installers, working from the plan you and I settled on at the estimate. Every job is backed by our satisfaction guarantee.

Before I started this business in 2023, I spent years doing upkeep for a property management company and chasing drafty rooms and damp floors back to where they started. That's why landlords and property managers call us too when they need a straight answer fast.

Basement insulation questions we hear
What is the best way to insulate basement walls in Fayetteville?
For an existing house, insulating from the inside is usually the way to go, because doing the outside of the foundation means digging deep around the entire house, which is costly and tears things up. Rigid foam board and spray foam are the safest choices for the inside of the wall.
How do I get my basement ready for insulation?
Start with a dry basement, because any water coming in has to be dealt with before insulation goes on the walls. If you've seen puddles, a damp floor or stains on the concrete, tell me at the estimate so I can trace where it's coming from. Before work starts I also check with the city's building office about what the job needs, and if a permit is called for we take care of the paperwork and the inspections.
Why does air sealing matter when insulating a basement?
Sealing keeps condensation off your walls, because warm indoor air that slips behind the insulation hits cold concrete and turns to water. That's why every seam in foam board gets sealed with caulk, good tape or canned spray foam. On a spray foam job, you can look over the finished wall yourself for gaps or shrinkage cracks that would let indoor air reach the concrete.
Does spray foam in a basement need to be covered?
Yes, in most basements foam needs to be covered by a fire or ignition barrier, and drywall usually does that job. The local building code sets what counts, so plan on a finished, covered wall from the start rather than bare foam.
How much does basement insulation cost in Fayetteville?
Your price comes from the estimate once I've seen the basement, because it turns on things like how many rim joists need sealing, how much plumbing and wiring we have to work around, and whether you're finishing a room or just covering bare concrete. What you get back on the power bill depends on the weather, your fuel cost, your heating system and how your household lives.
Can radon get into a basement in Fayetteville?
Yes. The Arkansas Department of Health says radon, a natural gas you can't see or smell, can get into homes through cracks and openings in the foundation, and testing is the only way to know your home's level. Breathing high levels can cause lung cancer, so if you've had a test, mention the result when you ask for an estimate.
