Ask for a vapor barrier estimate
I go under the house and check for water, piers and access before pricing anything.
Request an estimateDoes your crawl space need a vapor barrier?
Vapor barrier installation in Fort Worth puts plastic sheeting over the dirt in your crawl space and up the foundation walls and piers, so less ground moisture rises into the space under your floors.
Most people call me about a musty smell coming up through the house, cold floors, or wood under the house that looks damp, and before I'd sell you plastic, I want to know where the water's coming from. What moves the price is the size of the crawl space, how many piers we work around, how tall or low the space sits and how complicated the foundation's shape is, plus whether you stop at a sealed floor or close the whole space with drying equipment. The schedule mostly turns on whether a water repair has to happen first. Your own figure comes from the estimate I do on site.
How we handle vapor barrier installation
I start by going under the house to look at the floor, the walls, the piers and any water sitting on the dirt. If there's standing water, we clear it and get its source fixed before any plastic goes down, because sealing over a wet floor traps the moisture you're trying to stop. Then our crew lays the sheeting across the whole floor and up the foundation walls and piers, overlapping the seams and taping them so moisture doesn't slip through the joints. If you decide to close the crawl space fully, the drying equipment is part of the plan from day one, not something we add on after.
A vapor barrier handles the ground, but it's only one part of the house. If air is leaking out at the top, attic air sealing closes the gaps around lights, pipes and the hatch so less air gets pulled up through the floor. And when an older house needs more insulation without opening it up, retrofit insulation is how we add it to the walls and floors you already have.
What vapor barrier installation involves in Fort Worth
Fort Worth holds home building work to the International Residential Code, with some local changes of its own, and the city sets how that code is applied and enforced. Before we start, I check with the city's building office about what your job needs, and we take care of any permit and inspection on our end, so you're not the one making those calls.
A lot of the houses we get under sit on piers with low, tight crawl spaces and a small access hatch, so we plan the layout around every pier before the plastic comes off the roll. We see the same kind of crawl spaces on jobs in Haltom City and North Richland Hills.
Why call us for vapor barriers
I do the estimate myself
I come out, go under the house and give you the estimate myself, and then I run the job alongside our install crew. The person who saw where your water was coming from is the one making sure it's handled before the plastic goes down.
In business since 2020
I left an office job to learn insulation on a Fort Worth crew, and I started this business in 2020. Six years in, I'd still rather tell you to fix a leak first than sell you something that won't help.

Frequently asked questions
What does a vapor barrier in a crawl space do?
It slows ground moisture from evaporating into the space under your house, as long as it's fully sealed on the floor and walls. Gaps or open seams let that moisture back through and push the humidity up, so ask anyone you're getting a price from how they'll seal the seams.
What is the best way to deal with standing water before a vapor barrier goes in?
Fix it first. Crawl space guidance says drainage and moisture problems in and around the space have to be handled before it's sealed, so it stays dry once it's closed up, with any standing water removed and its source repaired. That's why some plans start with a repair step before any plastic, and I'll tell you plainly if yours does.
Is a closed crawl space better than a vented one?
Usually yes, when it's done properly. Research and real installations show that properly closed crawl spaces control moisture much better than wall-vented ones in temperate-humid climates, but a closed design needs a mechanical drying system, such as conditioned air or a dehumidifier, so that equipment belongs in the plan. When a crawl space has had moisture trouble, I lean toward closing it, as long as the drying side is budgeted from the start.
How much does a crawl space vapor barrier cost in Fort Worth?
A 12-mil vapor barrier with a commercial dehumidifier for a 1,500-square-foot crawl space in Fort Worth usually runs about $4,500 to $8,000 for the job. That's the typical range around here, not our quote. Your own number comes from the estimate after I've seen the space.
Can my dryer vent into the crawl space once it's sealed?
No. In a closed crawl space, exhausts from the dryer, kitchen and bathrooms, along with any discharge pipes, end outside the crawl space. I check where those lines run during the estimate, because rerouting one can be part of the job.
How do I know my crawl space vapor barrier is working?
Track the temperature and humidity down there after it's sealed, ideally for a full year, which is what crawl space guidance suggests. The same guidance suggests testing the moisture in the rim and floor joists, the wood framing that holds up your floor, so you know the wood is staying dry.

Attic air sealing
A house that leaks at the top keeps drawing air from underneath, so closing those attic gaps can help the upstairs stop running hot.
Retrofit insulation
If rooms still feel drafty or cold after the crawl space is dealt with, adding insulation to the existing house is usually the next thing worth looking at.
