Vapor barrier installation in Gastonia NC - a drier crawl space under your floors
Musty smell, damp dirt or a cold floor over the crawl space? We fix the water first, then lay a barrier that covers the ground.
What does a vapor barrier do for a Gastonia crawl space?
Vapor barrier installation in Gastonia means covering the dirt floor of your crawl space with heavy plastic, also called a vapor retarder, and carrying it up the walls, piers and footings so it helps keep ground moisture and soil gases such as radon from working up into your house.
Most calls start with a musty smell, a floor that's cold underfoot or a crawl space nobody has looked at since closing day, which is fair, because it's not a place anyone visits for fun. The price moves with the size of the space, the thickness you pick, any water that has to be fixed first and whether the crawl space is vented or sealed off, since a sealed, unvented space needs every seam and pipe opening closed with a lasting sealant and a vented one doesn't. The schedule mostly turns on that water repair and on any permit, and the estimate gives you your own number. We're licensed and insured, and if the barrier is part of a bigger project, the state's licensing board for general contractors requires whoever runs it to be licensed once the total project cost reaches $40,000.
What happens after you call about a vapor barrier in Gastonia?
Call or send us a message
We get back to you within one business day to set up a visit. We ask for your address early, because we work on both sides of the state line and the address decides which offices cover your job.
I come out and look underneath
I check the crawl space myself for standing water, vents and whatever's stored down there, then give you a free estimate with no obligation. It tells you what has to be fixed first, which thickness I'd use and that the barrier covers the whole space, so you can see what drives the number before you decide.
We fix, install and clean up
If you go ahead, we handle any permit paperwork and get the water problem fixed before anything goes down. Then our own crew installs the barrier, I check the work, and we clean up before we leave.
How we install a vapor barrier under your house
We start by clearing out what's stored down there, because the barrier has to lie on bare ground, and old paint cans make poor company for plastic. Then we find where any standing water is coming from and get it fixed, since a barrier laid over a leak just hides the leak. Our crew lays the barrier across the floor and runs it up the walls and piers so the ground is covered, not just the middle of it. Before we leave, we go over the whole thing for tears, because a rip from a knee or a toolbox is easy to miss and easy to fix while we're still down there.
A barrier takes care of the ground, and the rest of the house still counts. Damp air tends to follow gaps all the way up through the house, so attic air sealing, closing the gaps around lights, pipes and the attic hatch, often comes next. If the floors stay cold once the crawl space is dry, retrofit insulation adds insulation to a house you already live in without tearing it apart.
Get a vapor barrier estimate for your crawl space
We'll get back to you to set up a visit, and then I come out, look at the crawl space and write the estimate myself. If you've seen standing water down there or know whether the crawl space has vents, put that in your message.
Vapor barrier questions from Gastonia homeowners
How much does a crawl space vapor barrier cost in Gastonia?
We price it on site after I've been under the house, because the size of the crawl space, the thickness you pick and any water repair change the number more than anything else. A 20-mil barrier, the heavier plastic, costs more upfront than 6-mil, and clearing out your stored things ahead of time saves us a step.
How long does a 6-mil or 20-mil vapor barrier last?
One Carolinas cost guide says a 20-mil barrier lasts 15 to 25 years, while a 6-mil barrier may need replacing in as little as 5 to 7 years in a crawl space that gets walked through. If someone's down there for inspections or service calls, I'd usually spend more now on the thicker one and skip the replacements.
What has to be fixed before a vapor barrier goes in?
Any standing water has to go, and its source has to be found and repaired, most often a leaking pipe above or groundwater coming in from outside or under the floor. If that leak comes back, the moisture climbs right back up under your new barrier, so the repair goes in the plan before any plastic goes down.
Who issues construction permits for a project in Gastonia?
Gaston County Permitting issues construction permits, and before you apply there you need a zoning permit from the City of Gastonia. When a job needs a permit, we check which offices cover your address and handle the paperwork before work starts, and the county's inspectors then make sure permitted work meets state code.
How long does vapor barrier installation take?
Most of the time goes into getting the space ready, so I can give you a schedule once I've seen how much is stored down there and whether water needs fixing first. You can usually stay home while we work, since the crew is under the floor and not in your kitchen.
Does a vapor barrier help with radon in Gaston County?
It helps, because a well-installed barrier carried up the walls and piers helps minimize soil gases such as radon along with ground moisture, but it's no guarantee for any one house. The state health department publishes radon data for Gaston County, which is why radon comes up when we're working under houses around here.
Other work that pairs with a vapor barrier
Attic air sealing
Worth a look if upstairs runs hot or the power bill keeps climbing, since air leaking out the top of the house pulls more in from below.
Retrofit insulation
For older houses where the walls, floors or attic came up short on insulation and you'd rather not open everything up to fix it.
