Insulation Contractor in Bentonville, AR - Even Temperatures Upstairs and Down
C&J Fayetteville Insulation Company is an insulation contractor working in Bentonville, AR. We find out why a room runs hot, drafty or damp, then seal and insulate attics, walls, crawl spaces and basements to fix it.

Bentonville: bonus rooms and attic ductwork
A lot of our Bentonville calls come from the newer subdivisions that keep filling in around the city, two-story houses with a bonus room over the garage and the heat and air equipment up in the attic. Those attics usually aren't short on insulation in the middle. The trouble sits at the edges, over the garage and behind the knee walls, where coverage runs thin and the gaps were never sealed, so the upstairs runs hot all summer while the power bill climbs.
Closer to downtown and heading north toward Bella Vista, the houses get older, and more of them sit on crawl spaces or have an old attic layer that's packed down, damp or full of droppings. Those jobs start with what's already there, because I won't lay new insulation over a problem that hasn't been fixed.

Insulation work we do in Bentonville homes
Attic insulation
Newer Bentonville attics often have plenty of fill in the middle and barely any at the eaves, which is backward, because the edges are where the heat gets in. We even out the coverage and keep the eave vents clear so the attic can still breathe.
Attic air sealing
In a two-story house with a bonus room, drafts usually come through gaps around can lights, pipes, wiring and the attic hatch. We close those gaps before any insulation goes down, because insulation laid over an open gap just has air blowing through it.
Spray foam insulation
When the ductwork and air handler live in a Bentonville attic, foam on the underside of the roof brings that space inside the house so the ducts aren't sitting in summer heat. It costs more than loose fill, so I only recommend it when the equipment up there makes it worth it.
Insulation removal
Older houses near downtown often have attic insulation that's been soaked by an old roof leak or used by mice and squirrels. We pull it out and clean up before anything new goes in, so the smell and the damp don't stay trapped under a fresh layer.
Basement insulation
Houses built into a slope here often have a walk-out basement with a cold, damp wall on the uphill side. We find where the moisture is coming from first, then do the basement insulation that suits that wall.
Crawl space vapor barrier
Cold floors and a musty smell in an older Bentonville house usually trace back to a bare dirt crawl space. We lay a vapor barrier, a heavy sheet that keeps ground moisture from rising, before anything goes under the floor, because insulation over damp ground just holds the damp.
Working in Bentonville: permits, price and timing
In Bentonville, permits come from the Building & Fire Safety Division, which is part of the fire department. Its posted list covers building permits and plumbing, electrical, mechanical and fire system work but doesn't name insulation, so before we start I check with the division about what your job needs. When a permit is called for, we take care of the paperwork and the inspections, and waiting on it is usually what sets our start date. Plumbing, electrical and mechanical permits have to be pulled by a contractor licensed in Arkansas, and we're fully licensed and insured, so ask anyone you're comparing to show you the same.
Price comes down to what I find once I'm up there. The inches already in place, whether the old layer is damp or dirty and has to come out, how many gaps need sealing, how tight the attic is to crawl through and whether ductwork up there makes foam worth the extra cost all move the number, while the size of the job and any permit wait move the schedule. Bentonville is a short drive up from our base in Fayetteville, and we see the same newer two-story houses in Centerton and Rogers, so I know what to look for before I give you your own figure.

Bentonville insulation questions
How long does it take to get a trade permit in Bentonville?
Electrical, mechanical and plumbing permits in Bentonville are usually issued the same day or the next, and most need no review or extra drawings. Building permits take longer, because the city reviews the plans first and flags any problems before the permit is issued. If your job needs one, we work that wait into the schedule.
When can insulation work start in Bentonville if the job needs a permit?
Not until the permit is paid for and issued, going by the city's posted guidance. Starting early can bring extra fees or a stop work notice, so we book our crew once the permit is in hand.
Can I be my own general contractor on a remodel in Bentonville?
Yes, the legal owner of a permitted residential property can act as general contractor in Bentonville. You can't do the licensed work yourself, though, and you're responsible for the items the city lists on its Owner as Builder page, so its permitting guidance is the place to start. We can do the insulation inside a project you're running.
What happens if insulation covers work before it passes inspection in Bentonville?
The city's guidance says work covered before it's inspected, or before it passes, has to be uncovered at the builder's expense so the inspection can happen. On a remodel with open walls, we don't insulate until the work behind them has passed, because tearing out fresh insulation means paying for it twice.
How much does attic insulation cost in Bentonville?
Your price comes from your attic, mostly the inches already up there and whether the old layer has to come out first. Removal, a lot of gaps to seal or a cramped attic add to it, and a simple top-up over clean, dry insulation keeps it down. I'll give you your figure after I've been up there.
What is the best way to insulate a Bentonville attic with ductwork in it?
If your ductwork and air handler are up in the attic, spray foam on the underside of the roof is usually worth the extra cost, because it seals air while it insulates and keeps the ducts out of the heat. Without equipment up there, sealing the gaps and adding blown-in insulation, loose fill we blow through a hose, usually does the job for less. I'll tell you which one your house needs, even when it's the cheaper one.
