What does a vapor barrier do for an El Paso crawl space?
Vapor barrier installation in El Paso means laying a plastic ground cover across the dirt floor of your crawl space and up its walls and piers, so it helps keep ground moisture and soil gases like radon from rising into your house.
We're based in El Paso and work across the city and the cities around it, on both sides of the Texas and New Mexico line. Most crawl space calls start with a musty smell, damp insulation under the floor or a hatch nobody has opened in years. The price and the schedule turn mostly on how big the floor is, how much is stored down there, whether the space is vented or unvented, and anything that has to be fixed before the plastic goes down, like a leak or mold. I write an estimate that lists each step, so you can see what your job needs before anything starts.
Why El Paso homeowners call Wraptight El Paso Insulation Company for vapor barriers
I look at every crawl space
I come out to every job, go through the crawl space and write the estimate myself. Our installers work from that list, and I check their work before we leave.
Licensed and insured, permits checked
We're licensed and insured. Rules differ between El Paso, the county areas and the New Mexico cities, so I check your address with the right office and we handle any permit it needs.
Repairs named before plastic goes down
I learned the trade on a municipal crew where every job got checked, then started here in 2023. If a leak needs fixing before the plastic goes down, I'll tell you instead of covering it.
On this job, what counts is a cover that reaches every edge and doesn't seal a problem underneath it. Book a crawl space visit and I'll come take a look.
How our vapor barrier installation works
First we clear stored boxes and debris out of the crawl space, because a ground cover only does its job when it can reach every part of the floor. I look for mold before anything gets moved, and if there's any sign of it we slow down and handle it carefully, since stirring it up can spread it through the rest of the house. Then we lay the plastic across the whole floor, as close to every corner as the space allows, and run it up the walls, piers and footings. We leave the crawl space draining the way it already does, so the plastic doesn't change where water goes.
A ground cover deals with moisture coming up from the dirt, and it's often one piece of a larger fix. If the rooms upstairs run hot or drafty, attic air sealing closes the gaps at the top of the house, and in an older home retrofit insulation adds what's missing in walls and attics that are already finished. Plastic inside a wall is a different matter, because the Insulation Institute, a trade group, says a vapor retarder that lets almost no moisture through can lead to moisture problems on the inside of a wall in warmer climate zones.
New ground cover
This suits a crawl space with bare dirt or old plastic too torn to save. We clear the floor and lay fresh plastic from edge to edge and up the walls and piers.
Repairing the plastic you have
This suits a cover that's mostly whole with a few tears or loose edges. Patching usually costs less than starting over, and I'll tell you at the estimate whether yours is worth saving.
Ground cover with floor insulation
This suits a house with cold floors over the crawl space. Planning the plastic and the insulation together means our crew goes under the house once instead of twice.
How do you know your crawl space needs a vapor barrier?
A musty smell indoors
A damp, earthy smell in the rooms over the crawl space usually means ground moisture is rising into the house. Left alone, that moisture can feed mold on the wood down there.
Bare dirt under the house
If you open the hatch and see open dirt, nothing is holding back the moisture coming up from the ground. As long as it stays bare, that damp air keeps rising into the framing.
Torn or loose plastic
Old plastic that's ripped, bunched up or stops short of the walls leaves gaps where moisture gets through. Small tears are easy to patch now and harder once they spread.
Sagging, damp floor insulation
Insulation drooping between the floor joists or feeling damp usually means moisture is coming up from below. Wet insulation does little, so the floors above get colder while you wait.

Crawl space vapor barrier questions
These are the questions El Paso homeowners ask most before a crawl space job. If yours isn't here, call or send the form and ask it about your own house.
What does a crawl space vapor barrier do?
A crawl space vapor barrier is a plastic ground cover that helps cut down the moisture vapor and soil gases, such as radon, that rise from the dirt under your house. The Department of Energy's crawl space guide says it should cover all of the ground, or as close as is reasonably possible, and extend up the walls, columns and footings. When you compare quotes, ask whether each one covers the whole floor and its edges, and our written estimate spells that out.
How much does vapor barrier installation cost in El Paso?
Your cost comes down to the size of your crawl space floor, how much has to be cleared out and whether the space is vented or unvented. Repairing plastic that's mostly sound usually costs less than replacing it, and a leak or mold that has to be dealt with first adds to the job. I give you the price in a written estimate after I've seen the space.
Does my crawl space need sealed seams on the vapor barrier?
Sealed seams are listed for unvented crawl spaces, the kind with no vents to the outside, in the federal guide for this work. On those, the seams and the spots where pipes come through get a durable sealant that suits the plastic, so the kind of crawl space you have changes how much sealing your job includes. If you know which kind you have, tell us before I come out.
How do I keep moisture down in my crawl space after the vapor barrier goes in?
Check your indoor humidity now and then with a humidistat or moisture meter. NC State Extension guidance says to keep it below 60% and to consider a dehumidifier if it runs higher, though that advice was written for North Carolina homes, so treat it as a starting point for your own checks.
Who handles building permits in El Paso, and how does a permit close out?
Building permits in El Paso go through the city's One Stop Shop, and the city requires one to build, enlarge, alter, repair, move or demolish a building or structure. A contractor has to file the city's registration every year to be able to get permits, and every city permit has to be finalized with a final inspection, a certificate of completion or a certificate of occupancy. When a permit applies to your job, we take care of the application and the inspections.
How long does a crawl space vapor barrier installation take?
Laying the plastic is usually the quick part, and most of the time goes into clearing the crawl space and fixing anything that has to come first. I'll tell you what your schedule turns on when I write the estimate, and since this is plastic sheeting and not spray foam, you usually don't need to leave the house while we work.

Worth a look when the second floor feels hot and the power bill climbs, since leaks at the ceiling let cooled air escape into the attic.
