Do you need a vapor barrier in your crawl space?

A crawl space vapor barrier is a plastic cover we lay over the dirt under your Wichita Falls house. It can almost completely shut off one of the biggest sources of moisture in a home, so less damp works its way up through the walls into your rooms.

Most folks call because a room smells musty, the floor insulation is sagging or damp, or they just bought an older house and found bare dirt or torn plastic under it. The price mostly moves with how big the crawl space is, how easy it is to get into and whether water or mold has to be handled before a liner goes down. That last part sets the schedule too, along with checking on permits with the city. When I come out, you get a plain write-up of what I found and what we'd do.

How can you tell your crawl space needs a vapor barrier?

A musty smell inside

If the house smells like a damp basement, especially after rain or on muggy days, moist air from under the floor is usually finding its way up. Left alone, that damp keeps working on the wood down there and on the air upstairs.

Bare dirt or torn plastic

When you look through the access and see open ground, or old plastic that's ripped, bunched up or missing in spots, nothing is stopping ground moisture from rising. It's an easy fix early on and a harder one once the wood has stayed wet for a while.

Wet insulation or dark spots

Floor insulation that's hanging down and soggy, or wood with dark or fuzzy patches, usually means moisture has been at it for some time. Don't go scraping at spots like that. Tell us what you saw, because mold is something we plan around before anyone crawls in.

How we put in a crawl space vapor barrier

Here's how it goes. I get under the house first, take a humidity reading and look for standing water, wet spots and mold, because that tells us whether a dehumidifier belongs in the plan before you spend a dime on one. If I find mold, we stop there and get the right help in before anyone starts poking around. Once the crawl space is safe to work in, our crew clears out old debris and torn plastic, lays the new liner over the dirt, and I walk you through what's down there now so you know what to watch for.

A crawl space liner is one piece of moisture control, and if your trouble shows up in the walls or another part of the house, our vapor barrier installation work covers those spots. Damp air that gets past the floor tends to rise and slip out through gaps in the ceiling, so some folks pair the liner with attic air sealing, which closes those gaps before any new insulation goes in.

  • Liner on its own

    This suits a crawl space where the humidity reading comes back in a good range and no water is coming in. Covering the ground is often all that kind of crawl space needs.

  • Liner plus a dehumidifier

    This suits a crawl space that still reads damp or takes in water in wet weather. The liner stops the ground moisture and the dehumidifier pulls the rest out of the air, though it needs power and regular upkeep.

What changes a crawl space vapor barrier job in Wichita Falls

Wichita Falls Building Inspections issues permits here, and the city says construction work has to follow city codes with the right permits and licenses. The same office inspects work for code and licenses and registers contractors, so it's the place to check on whoever you hire. Whether your liner job needs a permit isn't something I'd guess at, so we check with the office before we start, and when the job calls for a permit we handle the paperwork and the inspections for you.

Wichita County sits in what's called a Mixed-Humid climate zone, so muggy stretches are part of the year here, which is why I'd rather take a reading than assume a crawl space is dry. We see the same older crawl spaces with bare dirt and worn-out plastic on jobs in Burkburnett and Iowa Park.

What happens after you call about your crawl space?

  1. Call or send us a message

    Call (940) 298-1123 or use the form on this page, any day until 11 PM, and tell us a little about the house. We'll set a time for me to come take a look.

  2. I look under your house

    I come out myself, check the humidity, look for water and mold, and walk you through what I found and what I'd take care of first. You get it written up in plain words, so you know what the job involves and why before you decide anything.

  3. We check permits and protect your house

    Once you say go, we check with the city's inspections office, which keeps weekday hours of 8 to 5, then cover the floors along the path to the crawl space access. Any repairs come first so the liner never goes down over a problem.

  4. We lay the liner and walk it

    Our crew lays the liner over the dirt, and then I go over the finished crawl space with you, flashlight in hand. You'll know what it looked like before, what we did and what to keep an eye on.

Frequently asked questions

Is a crawl space vapor barrier worth it in Wichita Falls?

For most houses with a dirt crawl space, yes, because covering the ground keeps high moisture from slowly breaking down the floor framing, the wood that holds your floor up. That wood is a lot harder to fix than the dirt is to cover.

How thick should a crawl space vapor barrier be?

University extension guides put the minimum at 6 mil, a measure of plastic thickness, with an older guide calling for at least 6 and a newer one recommending 6 to 8. The older guide also overlaps the sheets and runs the liner part way up the wall, so ask anyone who quotes you how their liner handles both.

How do I check the humidity in my crawl space?

Set a moisture meter or humidistat down there and read it, and the guidance is to keep it below 60%, with 30 to 50% about ideal. While you're looking, check for leaks or wet spots, and I'll take my own reading when I come out.

Do I need a dehumidifier with a crawl space vapor barrier?

If your reading stays above that 60% mark, the guidance is to consider one, and its drip pan needs emptying and cleaning on a regular basis. If it needs a new circuit, the Texas Department of Licensing and Regulation says that takes a licensed electrician working through a licensed electrical contractor, so plan on that being part of the job.

What is the best way to handle mold in a crawl space?

Leave it alone until you have help, because digging around can spread mold through the house, and that's a serious risk for anyone with asthma, allergies or a weak immune system. Extension guidance suggests talking to a doctor or bringing in a professional before anyone does a thorough check, so mention any spots or smells when you call.

How much does a crawl space vapor barrier cost in Wichita Falls?

The price comes down to the size of your crawl space, how hard it is to get into and whether water, mold or old debris has to be handled first. A thicker liner or a dehumidifier on a new circuit adds to it, and after I look it over I write up what I found and what we'd do, in plain words.
