Vapor barrier installation in Evansville IN - leaks found first, then the dirt covered
Musty smell, damp dirt or a cold floor over the crawl space? We find the leaks first, then cover the ground with plastic sheeting.
Do you need a vapor barrier under your house?
Vapor barrier installation in Evansville means covering the bare dirt in your crawl space with plastic sheeting, so the ground isn't sending damp air up under your floors. It works alongside fixing the leaks that let water in, not in place of it.
Most people call because of a musty smell, damp dirt they spotted when the plumber was down there, or floors that stay cold all winter. The price mostly follows how big the crawl space is and how hard it is to work in, since a low, tight one full of old junk takes more than a clean one you can sit up in. The schedule turns on what the leak check finds, because a gutter or plumbing leak gets fixed before any plastic goes down, and on whether your building office wants a permit, which we ask about before work starts and handle when one's needed. Your own number comes from the estimate.
How we handle vapor barrier installation
I crawl in first and look for where water is getting in, because plastic over an active leak just keeps it company. Once any repair is done, we measure the floor with room for the panels to overlap, and one maker's guide sets a minimum overlap that it says can vary with local codes. Then the sheeting goes down over the dirt and around the piers and pipes. If you want the walls covered too, we stop the liner short of the sill plate, the wood the house sits on at the top of the foundation, so there's a strip of bare wall left where someone can check for pests later. Walls below ground get their own plan, because plastic in the wrong spot traps water, and a building science guide warns that heavy vapor control on the inside of walls below ground holds moisture in and leads to damage over time.
The crawl space is the bottom of the house, and the top is usually where the heat goes. If upstairs runs hot in summer and drafty in winter, attic air sealing closes the gaps around lights, pipes and the hatch before anything else goes up there. Older houses with thin or settled insulation can get retrofit insulation, added to what's already in the walls and attic without tearing the place apart.
Why Evansville homeowners call A&B Evansville Insulation Services for a vapor barrier
I write your estimate myself
I learned the trade on another crew and started this business in 2023, and I come out to look at the crawl space and write the estimate myself. Our own crew does the work and I'm on most jobs with them, so what I saw under your house is what we plan for.
Licensed and insured for Evansville work
Evansville and Vanderburgh County require licensed contractors for work done on buildings, which means passing a written exam and an experience check and showing proof of insurance. We're fully licensed and insured, so you're not left wondering who's under your floor.
Straight answers on older crawl spaces
We're based in Evansville and work across the area, including Henderson, KY, Mount Vernon, Boonville, Princeton and other cities nearby, and most of our calls come from older homes. When a crawl space needs a roof, gutter or plumbing fix before it needs plastic, I'll tell you that rather than sell you sheeting over the problem.
On this job, the order is what counts. Have a rough idea whether anyone's checked the crawl space for leaks and what's stored down there, then call (812) 205-2872 or send us the form. The work is backed by our satisfaction guarantee.

Questions before you book a vapor barrier
What does a crawl space vapor barrier actually do?
It covers the bare soil in your crawl space with plastic sheeting, so ground moisture stays under it instead of rising into the space below your floors. It's meant to work alongside the checks that keep the crawl space sealed against leaks, so it won't fix a pipe or a gutter that's sending water down there.
How do I get my crawl space ready for a vapor barrier?
Clear out what's stored down there, because one maker's checklist asks for the crawl space to be cleaned out, or anything that can't be moved covered, before installation starts. That checklist and a university extension checklist both call for a leak check too, so tell me about any wet spots you've seen. If your house sits in one of Vanderburgh County's flood hazard areas, which flood from time to time, mention that when you call.
How much does vapor barrier installation cost in Evansville?
I can't give you a fair number until I've seen your crawl space, because no two price out the same. Size and access set most of it, and the rest comes from how much has to be hauled out first, whether the walls get covered, how many piers and pipes we work around, and any repair the leak check turns up.
Do I have to leave the house while the vapor barrier goes in?
Usually not, because laying plastic sheeting doesn't involve spray foam or anything with fumes, so there's no re-entry time, the wait before you can come back inside. We'll be going in and out of the crawl space access, so keep kids and pets clear of it while the crew's working.
Who issues building permits in Evansville for crawl space work?
The city's Building Commission issues building permits for work on any structure or its parts. Its list names waterproofing but doesn't mention vapor barriers, so the commission is the one to say whether your job needs a permit, and city and county ordinances also call for inspections on work done to buildings. As I said up top, we ask before work starts and handle the permit if one's needed.
How do I get a permit to install my own vapor barrier in Evansville?
You'd ask the city, which may issue a permit without the usual contractor license to you or your immediate family for work on the home you live in now. The city lays out who needs a license, and if you go it alone, do the leak check first, since plastic over a leak just hides it.
Other work that pairs with a vapor barrier
- Attic air sealing
If the upstairs bedrooms bake in summer and the power bill climbs anyway, the gaps in the attic floor are often the reason.
- Retrofit insulation
For an older house whose walls and attic never got much insulation, this adds more without opening up every room.
