Insulation contractor in Cave Springs, AR - sealed first, then insulated
C&J Fayetteville Insulation Company is an insulation contractor working in Cave Springs, AR. We find out why a room runs hot, cold or drafty, then seal the gaps and add insulation in attics, walls and crawl spaces.

Cave Springs: newer subdivisions, older wooded lots
Cave Springs is a small city tucked between Rogers and Bentonville, and most of the houses we're called to here are on the newer side, built in the subdivisions that have filled in around the older part of town.
That mix shapes the job. In the newer homes, the attic usually has builder-grade blown-in that looks fine in the middle and runs thin out at the edges, and the room over the garage is the one people call about. The older houses on bigger, wooded lots tend to have insulation that's settled or gotten wet somewhere along the way, and cold floors there often start in the crawl space, so I look underneath before I say anything about the attic.

Insulation work we do in Cave Springs
Attic air sealing
In the newer Cave Springs subdivisions we find open gaps around can lights, bath fans, pipes and the attic hatch, and that's air you already paid to heat or cool slipping out. We do air sealing, closing those gaps with foam and caulk, before any insulation goes on, so the new layer isn't fighting a draft.
Blown-in insulation
Builder-grade attics here often run deep in the middle and thin at the edges, which is backward, because the edges over the outside walls need it most. We blow in loose fill out to the eaves and set baffles so the eave vents stay open and the attic keeps breathing.
Wall insulation
The room over the garage is the usual complaint here, and the short knee walls between that room and the attic are often thin or bare. We add wall insulation to those walls and cover the backs so it stays in place and actually does its job.
Crawl space vapor barrier
Many of the older homes on the wooded lots sit over crawl spaces, and cold floors or a musty smell usually start down there. We lay a vapor barrier over the dirt to keep ground moisture out of the framing, then talk about insulating the floor once it's dry.
Insulation removal
When old insulation has been soaked or is full of droppings, laying new material on top just hides the problem. We vacuum the old material out and clean up, and we make sure whatever caused it has been fixed before anything new goes in.
Spray foam insulation
Some houses here have the ductwork and air handler up in the attic, outside the part of the house you heat and cool. That's when foam on the underside of the roof starts to make sense, because it brings the attic and the ducts inside the house.
Working in Cave Springs: permits, licenses and price
City permits in Cave Springs go through the Planning & Development Department, and the Building Department enforces the state codes. The city's fee list names building, renovation, HVAC and other work but doesn't single out insulation, so before we start I check with the city about what your job needs, and when a permit is called for we take care of the paperwork and the inspections. If one's needed, the start date waits on it. Two things are worth checking on any contractor here: a home improvement license from the state's Residential Contractors Committee, and a city business license, which Cave Springs requires of anyone doing business inside city limits. We're fully licensed and insured.
Price and schedule turn on the same few things: how big the attic is and how easy it is to get into, how many inches are already up there, whether old material has to come out first, how many gaps need sealing, and whether the job calls for foam or loose fill. I started this business in 2023 after years of chasing drafty rooms and high power bills for a property manager, and I come out to look at every job myself, so the number you get at the estimate is for your house. We're based in Fayetteville, and our own installers do the same work here that they do in Lowell and Springdale.

Cave Springs insulation questions
How much does attic insulation cost in Cave Springs, AR?
I can't give you a fair number until I've been up in your attic, because the price turns on how much is already there and what has to happen before anything new goes in. Wet or dirty material that has to come out adds to the job. Foam costs more and seals air while it insulates, but for most attics sealing the gaps and topping up with loose fill is the better buy, unless your ductwork lives up there.
How long does attic insulation take, and do we have to leave the house?
For air sealing and blown-in insulation you can usually stay home while we work. How long we're up there depends on the attic size, how many gaps need sealing and whether old material comes out first, and I'll tell you before we book. Spray foam is different, because everyone, kids and pets included, stays out until the re-entry time, the wait before it's safe to come back in, and I'll give you that time for the product we'd use.
Does an insulation contractor need a state license in Arkansas?
Yes, a home improvement contractor working on your house needs a license from the state's Residential Contractors Committee unless the job is exempt. One exemption covers a project that costs $2,000 or less, but it doesn't hold if a bigger job is split into separate contracts under $2,000. Ask any contractor for the committee license before you sign.
Can I insulate my own house in Cave Springs without a contractor license?
Yes, Arkansas exempts the owner of a single-family home who acts as their own contractor on their own property. That exemption covers the state contractor license only, so it doesn't settle anything you'd need to sort out with the city. If you do the attic yourself, seal the gaps first and keep the eave vents clear.
What causes the room over the garage to be hot and cold in my Cave Springs house?
Usually it's the floor over the garage and the short attic walls around the room, which tend to be thinly insulated and full of gaps. We seal those gaps, insulate the knee walls and the floor, and check the duct run to that room, since it's often the longest one in the house.
How do I know if my old attic insulation needs to be removed?
It needs to come out if it's been wet, matted down or full of droppings, because new insulation on top just covers the problem. Look from the hatch for dark stains, flattened spots or signs of animals, and I'll check the framing for moisture when I come out. If what's up there is in good shape, I'll tell you to leave it and top it up.
