Crawl space insulation in Auburn AL - warmer floors and a dry space under the house
Cold floors, a musty smell or a climbing power bill? We deal with the dampness under your house first, then insulate so the floors stay comfortable.
Should I insulate the floor or seal my crawl space?
Crawl space insulation in Auburn, AL means fitting batts or spray foam between the floor joists, or turning a vented crawl space into one that's sealed, insulated and dry. Either way, the goal is a floor that stops feeling cold and framing that isn't sitting in damp air.
Most people call me about cold floors, a musty smell or a power bill that keeps going up, and the cause usually starts under the house. Research on crawl spaces in mixed and hot-humid climates found vented ones tend to get wetter, not drier, with moisture condensing on the floor framing until mold and wood damage follow, so I treat dampness as part of the job and not an add-on. The price turns on how big the space is, how easy it is to move around in, whether old wet batts have to come out first through insulation removal, and whether we insulate the floor or close the space. The schedule mostly turns on fixing any moisture problem first and settling the permit question, and the estimate lays all of it out in the order we'd do it so you can hold it next to another quote.
What our crawl space insulation work includes
Under the house, the first thing I look at is moisture. I check the vents, any gas equipment down there and your termite bond before we choose between insulating the floor and closing the space, because any one of those can rule a choice out. If we go with the floor, our crew seals the holes around pipes and wires in the subfloor first, then fits the batts snug between the joists with no gaps or squashed spots, since insulation with a draft running past it doesn't do much. Spray foam is the other way to do the floor, and it has a high R-value, which is how well insulation slows heat. Foam costs more and seals air while it insulates. Batts over well-sealed gaps usually win under a floor, unless your ductwork runs down there, and then I'd lean toward foam.
Crawl space work often ties into the rest of the house. If the rooms above still feel drafty once the floor is done, wall insulation is usually the next place to look, and air sealing services close the gaps that let outside air in no matter how much insulation sits there.
Crawl space insulation rules and conditions in Auburn
Auburn's Inspection Services issues the city's mechanical permit, which covers installing or changing air conditioning and ventilation, and its list doesn't name crawl space insulation. That doesn't settle whether your job needs a permit, especially when sealing the space means touching the heating and cooling side, so before we start we check with the office for your address and pull any permit the work calls for.
On jobs around here we find plenty of older houses on vented crawl spaces, with batts hanging off the joists and sometimes a gas furnace or water heater sitting down in the dirt. We see the same kinds of houses in Opelika and Tuskegee, and in many other cities around Auburn, so the moisture check comes first wherever we're crawling.
How crawl space insulation works
Call or send the form
Call (334) 780-0054 or fill out the form and tell us what's bothering you, whether it's cold floors, a smell or the power bill. We get back to you and set a time for me to come look.
I look under the house
I go into the crawl space, check the moisture, vents, equipment and old insulation, and ask what you've noticed upstairs. You get a written estimate with the steps listed in the order we'd do them, so you can see what's driving the price.
Permit check, then the install
Before work starts we check the permit question with the office for your address. Then a crew lead runs the install, and the gaps get sealed before any insulation goes up.
Walk the finished job together
When the crew wraps up, I look the work over and walk it with you, under the house if you want to see it. I'd rather you see the sealed gaps yourself than take my word for it.
Get a written crawl space estimate in the order we'd do it
We reply to every call or form within one business day. I come out to your house, look at the crawl space and write a free estimate with the work listed step by step. There's no pressure and no obligation, so you can take it and compare it with any other quote.
Questions before you book crawl space insulation
Should I seal my vented crawl space in Auburn?
Sealing can work, but it takes more than closing the vents, because shutting the vents alone can raise the moisture under your house. If a furnace or water heater that burns fuel and draws its air naturally sits down there, a closed space can become deadly, so that equipment gets checked before anything else.
Can I insulate my crawl space walls instead of the floor?
Only if the crawl space isn't vented to the outside, because Alabama's residential energy code allows wall insulation in place of the floor only in a closed space. The same rule calls for a strip just below the floor joists to stay open on insulated walls, so termite inspectors can still see the wood.
How much does crawl space insulation cost in Auburn, AL?
Across the US, insulating a crawl space usually costs about $3 to $6 per square foot, which is the going range for the work and not a quote from us. Your own number comes from the estimate, after I've seen how much the moisture side needs before any insulation goes in.
Will sealing my crawl space affect my termite bond?
It can. One foam maker's guide says homeowners who seal a vented crawl space often have their termite bonds or warranties cancelled, so call your termite company before we close anything, and keep that open inspection strip in mind if the walls get insulated.
How do I keep a sealed crawl space dry?
A sealed crawl space still needs a way to dry out, and one of the most effective is a small supply of conditioned air from your heating and cooling system. That treats the space as part of the house instead of a closed box under it, and I'll go over it with you before we decide to seal.
What causes a damp subfloor over a crawl space?
Usually it's damp crawl space air meeting a floor that the air conditioning keeps cool. Research on hot-humid climates found the subfloor generally stays drier in the cooling season with higher thermostat settings, flooring that lets moisture vapor pass through and under-floor insulation that lets less through.
Why Auburn homeowners call Quality Auburn Spray Foam Insulation for crawl spaces
The owner checks every crawl space
I come out to look at the job and write the estimate myself, a crew lead runs the install, and I look over the work before we leave. The person who told you the gaps would be sealed is the one who checks that they are.
Doing it in order since 2013
We've been in business since 2013, and I learned under a contractor who made me redo anything that wasn't right. A covered mistake is still a mistake, so the gaps, wiring and moisture get handled before anything goes over them.
Licensed and insured in Alabama
We're licensed and insured. Alabama's home builders licensure law covers paid repair or improvement of someone else's home when the job costs more than $10,000, so it's fair to ask anyone you're comparing how they're covered.
Under a house, what matters most is the part you won't see again once it's covered. Send us your details or call (334) 780-0054, and I'll come take a look.
