Does your crawl space need a vapor barrier?

A crawl space vapor barrier is a sheet of heavy plastic spread over the dirt under your house, and when it's sealed to the walls it keeps moisture from the ground out of your floor framing. Tifton Spray Foam Insulation puts in crawl space vapor barriers for homes in Tifton, GA and the cities around it.

Most people call us about a musty smell coming up through the floor, a damp crawl space or a floor that's started to feel soft, and the plastic is only part of the answer. The price moves with how big the crawl space is, whether you want a ground cover alone or a fully closed crawl space with a dehumidifier, how heavy a liner you need and what has to be fixed first. The schedule mostly turns on those fixes, because water and pest problems get handled before we cover the ground, and the written estimate lists each area and material so you can see where the money goes. If your floors run cold, crawl space insulation pairs well with the barrier.

How we put in a crawl space vapor barrier

I go under the house first and look for water coming in, damp wood and pest damage, and you get a list of anything that should be fixed before the plastic goes down, because a liner laid over a leak or a termite problem just hides it. Then we talk through a ground cover alone versus a fully closed crawl space, and I check any gas furnace, water heater or other fuel-burning equipment before anyone closes a vent. Once the fixes are done, our crew spreads the sheeting across the whole ground, overlaps and tapes the seams and runs the edges up the walls with fasteners, cleaning and drying each spot first because tape only holds on a clean, dry surface.

A crawl space liner is one kind of vapor barrier installation, and we bring the same taping and sealing to walls and other spots where moisture needs stopping. If the power bill is part of why you called, attic air sealing closes the gaps at the top of the house where your cooled air slips out.

  • Ground cover alone

    This suits a crawl space that stays fairly dry once any water problems are fixed, and it leaves the vents as they are. If someone crawls down there to service equipment, a thicker reinforced liner holds up to the traffic better than plain thin sheeting.

  • Fully closed crawl space

    This suits a crawl space that stays damp or has ductwork running through it, because the liner covers the floor and walls and a dehumidifier or a supply of conditioned air keeps the space dry. It costs more and takes more than plastic, since kitchen, bath and dryer exhausts have to end outside the crawl space, but it's usually the one I'd pick when the ducts live down there.

What changes a crawl space vapor barrier job in Tifton

The City of Tifton's Building and Permitting office issues permits here, and its list names new construction, renovations and additions but not crawl space vapor barriers, so that list alone doesn't tell you whether your job needs one. Each city and county has its own office, so we check with the one where your home is and take care of the permit paperwork when the job calls for it, whether you're in Tifton or out in Sylvester or Moultrie.

When wood-destroying fungi turn up under a house, a Georgia Department of Agriculture rule sets how they're treated, and that includes a vapor barrier over at least 90 percent of the bare soil. Plenty of the crawl spaces we get under have open vents and bare dirt, so I check the joists and sills for soft or stained wood before we talk about plastic, because a liner won't fix rot that's already there.

Why Tifton homeowners call Tifton Spray Foam Insulation about their crawl space

  • I do the estimate myself

    I'm the one who crawls under your house and writes the estimate, and I run the job while our crew does the work. The person who saw the problem is the one making sure it gets fixed.

  • In business since 2017

    We've been at this since 2017, and I learned under a boss who made me tear out and redo anything that wasn't right. Once the plastic's down nobody looks under it again, so I don't cover up a problem.

  • Licensed and fully insured

    We're licensed and fully insured, so you're not the one carrying the risk of somebody working under your floor. Ask to see it when I come out.

  • Based right here in Tifton

    We're based in Tifton, GA and work across the cities around it, including Adel and Fitzgerald. If your city isn't one of those, give us a call and ask.

On a crawl space, what counts most is what gets found and fixed before anything is covered, so the first step is a good look underneath. Send us a request or call (229) 479-8005 to set that up.

Get a free written estimate for your crawl space

We'll reply within one business day to set a time for me to come look under your house. The estimate is free, done on site and carries no obligation. You get it in writing, with each area and material listed and anything that needs fixing first.

What happens after you call about your crawl space

  1. Call or send a request

    Call (229) 479-8005 or use the form, and we'll set a time for me to come out. If you have a termite contract, have your pest control company's name handy.

  2. I look the house over

    I check the crawl space, attic and walls, ask about gas appliances and any termite contract, then leave you a written estimate. It lists each area and material, so you know what you're paying for and why before anything starts.

  3. Fixes first, then sealing

    If you go ahead, the water or pest fixes on your list get handled first. Then our crew lays and seals the barrier, and nothing gets covered until it's been checked.

  4. We walk the job together

    When the crew's done, I go over the finished crawl space with you. You'll see the taped seams and the edges on the walls, since that's the part nobody looks at again.

Frequently asked questions

What causes a damp crawl space when the vents are open?

Open vents usually make a crawl space damper, not drier, in hot-humid and mixed climates. Humid outside air comes in, the moisture condenses on the cooler wood floor framing, and that feeds fungus and damages the wood your floor sits on.

Can I just close my crawl space vents to keep moisture out?

No, closing the vents by themselves can actually raise the moisture under your house. A sealed, dry crawl space also needs a sealed liner and a way to dry the air, and any fuel-burning equipment that draws its air naturally has to be planned for first, because shutting off its air can be deadly. That's the equipment check I mentioned, and it comes before any vent gets touched.

How much does a crawl space vapor barrier cost in Tifton, GA?

The price depends mostly on the size of the crawl space and whether you want a ground cover alone or a closed crawl space with a dehumidifier. A heavier reinforced liner, debris that has to come out and any water or pest repairs add to it, and the written estimate after my visit lists each area and material.

Where does a crawl space dehumidifier drain its water?

Georgia Department of Agriculture guidance says a dehumidifier conditioning a closed crawl space has to drain its water automatically, by gravity, to a sump pump or into your air conditioner's condensate pump. That way nobody has to crawl under the house to empty a bucket.

How do I get my crawl space ready for a vapor barrier?

Clear out anything stored down there and any loose junk, because the cover has to reach every part of the ground to do its job. If something's too heavy or awkward to move, tell me at the estimate and we'll plan around it.

Will a closed crawl space affect my termite contract?

It can, so ask your pest control company to confirm a closed crawl space won't get in the way of its treatment or affect its warranty, if your contract has one. I ask about termite contracts at the estimate for that reason, and it's easiest to get that answer before work starts.

  • Vapor barrier installation

    If moisture is reaching walls or other spots besides the crawl space, a barrier there keeps damp air out of insulation and framing you can't see.

  • Attic air sealing

    When the upstairs runs hot or the power bill climbs, sealing gaps around lights, pipes and the attic hatch keeps cooled air in the rooms instead of leaking out the top.

A crawl space that's been damp a while usually has a surprise or two down there, and those are a lot easier to deal with before the plastic goes down than after.
