Crawl space insulation in Evansville IN - warmer floors over a dry crawl space
Cold floors, musty air or damp walls under the house? We fix the water first, then seal and insulate the crawl space.
Should you seal and insulate your crawl space?
Crawl space insulation in Evansville usually means sealing the crawl space under your house and lining its inside walls with rigid foam. Any ducts and heating gear down there then sit in a sealed, insulated space, the floors and pipes above stay warmer in winter, and the floor framing is less likely to sweat in a humid summer.
Most people call because the floors are cold, the house smells musty, or the old insulation under the floor is hanging from the joists like laundry nobody came back for. The price mostly turns on how big the space is, how much room there is to work, how much old material has to come out, whether water needs fixing first and whether you need a new crawl space vapor barrier. The schedule depends on that water work and on any permit, which we check with the building office for your address before we start. I'll come out, look at your crawl space and give you a figure for your house.
What our crawl space insulation job includes
I start by crawling the whole space with a light and checking the walls and floor for water, plus old insulation that's soaked or full of droppings. Water gets fixed before any foam goes on the walls, because a wet crawl space doesn't get better by being insulated. Then we pull out the bad material and close the old vents and gaps to the outside. Next we lay a plastic sheet over the dirt and up the walls to slow ground moisture, and fit rigid foam board to the inside of the foundation walls. A sealed crawl space also needs a way to dry out, so we work that plan out with you up front, not after the foam is up.
The crawl space is only one way outside air gets into your house. If the rooms above still feel drafty, air sealing services for the rest of the house usually help more than another layer anywhere. Older houses with cold outside walls can also need wall insulation, and I'll tell you on the visit whether that's worth doing now or can wait.
Why Evansville homeowners call A&B Evansville Insulation Services for crawl spaces
I write your estimate myself
I come out, get down in the crawl space and write the estimate myself, and our own crew does the work with me on most jobs. The person who looked is usually the one under your floor doing it.
Licensed and insured crawl space crew
We're fully licensed and insured. Evansville runs a contractor licensing program to put contracted work in the hands of qualified, licensed people, and that's the bar to hold anyone working under your house to.
Back in the trade since 2023
I learned insulation on another outfit's crew and came back in 2023 to start this business. With fresh eyes I kept seeing leaks skipped and insulation piled on top, so we seal first.
Used to older Evansville crawl spaces
Most of our calls come from owners of older homes in and around Evansville, and those crawl spaces usually carry a few decades of patch jobs. I'd rather tell you to fix the gutters or the wiring first than sell you foam that won't help.

Questions before you insulate a crawl space
What does crawl space insulation cost in Evansville?
Insulating a crawl space in Evansville usually costs about $1,500 to $6,800 per job. Where yours lands depends mostly on the size of the space, how much old insulation and debris has to come out, and whether water has to be fixed first. I'll give you your own figure after I've been down there.
How do I keep a sealed crawl space dry?
A sealed crawl space needs a steady way to dry out, and the usual one is a small supply of heated or cooled air from your home's heating and cooling system. That treats the crawl space as part of the house rather than the outdoors, which is why the air supply gets settled before the job starts.
How do I fix water coming into my crawl space walls before insulating?
Find where it's coming in and stop it there, because the standard guidance is to check the walls for water and fix any leak before insulating. Usually it's gutters, downspouts or ground sloping toward the house, and sometimes a crack in the wall. If the fix isn't our kind of work, I'll tell you who to call, and we pick the job up once it's dry.
Who oversees building permits in Evansville and Vanderburgh County?
The Building Commission for the City of Evansville and Vanderburgh County oversees the building codes for residential alterations and repairs, so it's the office to ask about crawl space work. Projects should also check with the Area Plan Commission before a building permit. We ask the office that covers your address before work starts, and when the job calls for a permit, we handle it.
Does foam insulation in a crawl space need to be covered?
Usually yes, because most codes require a fire-resisting cover such as gypsum board over foam insulation. Some foams can give off toxic or flammable gases when they get hot, so we plan the cover into the job and the estimate from the start.
Should I test my Evansville house for radon?
Yes. The EPA's radon map for Indiana says all homes should be tested, whatever zone the county falls in. Local rules for crawl space work also cover radon, along with fire safety and insect control, so it's worth bringing up when the building office looks at your job.
Other work that often goes with a crawl space
- Air sealing services
Gaps around windows, outlets and the attic hatch can keep the house drafty no matter what's under the floor.
- Wall insulation
Cold outside walls in an older house lose heat that a finished crawl space can't make up for.
- Crawl space vapor barrier
Bare dirt or torn plastic under the house keeps feeding ground moisture into the space.
