How do you know your crawl space needs a vapor barrier?
Most of these show up well before anything under the house is ruined, and catching them early usually means a simpler fix to the cover and the water feeding it.
Bare dirt under the house
You open the hatch and there's nothing but soil. Ground moisture and soil gases have a clear path up toward your floors, and they keep coming until it's covered.
Torn or pushed-aside plastic
Old plastic gets shoved around whenever someone crawls in to fix a pipe. Every gap lets damp through, but a mostly whole cover may only need a repair.
A musty smell in the house
A damp, earthy smell in the rooms above usually starts with wet ground under the floor. It doesn't go away on its own while the soil stays uncovered.
Damp soil after the sprinklers
If the dirt along one wall is wet after watering, the water's coming from the yard. Plastic alone won't stop that, so it's worth finding before the cover goes in.
Puddles against the foundation
Water that sits next to the house after rain usually means the ground slopes toward it or there's no drainage there. Left alone, it soaks the soil under your floors.
Damp boxes stored down there
Boxes or tools you keep in the crawl space feel damp or smell stale. That means moisture is getting into the space, and anything stored there keeps soaking it up.
How we put in a crawl space vapor barrier
A crawl space vapor barrier is plastic sheeting laid over the bare ground under your house, and it also helps keep soil gases from drifting up into your rooms. For a crawl space vapor barrier in City of Atwater, CA, I start in the yard, because most of the water in a vented crawl space comes from outside, through ground that slopes toward the house, missing drainage or sprinklers soaking the foundation. Plastic can't fix that by itself, so I'll show you where the water's getting in, and some fixes are as simple as aiming a sprinkler head away from the wall. Then I ask how you use the space down there, since the right liner depends on how often someone goes in to store things or reach equipment, and we can lay a runner or extra plastic along a path to the furnace so it holds up to the traffic. Our crew clears out debris, lays the plastic so water under the house keeps draining the way it already does, and secures it at the edges. The size of the crawl space, how tight it is to get into, how much has to come out first and whether an old cover gets pulled or patched are what move the price and the schedule, and you'll get a written price for yours after I walk you through what I found.
Once the floor's covered, a lot of homeowners turn to the drafty rooms and the power bill, and that usually starts upstairs with attic air sealing, which closes the gaps around lights, pipes and the hatch so insulation isn't fighting a draft. If you need plastic somewhere other than under the house, that's our vapor barrier installation work, and I can look at both while I'm out.

Crawl space cover questions
These are the questions I hear most when I'm standing in someone's yard next to a crawl space hatch. If yours isn't here, call and ask about your own house.
Does a vented crawl space need a vapor barrier?
Yes, the plastic ground cover belongs in a crawl space whether it's vented or sealed. Vents move air, but the damp still comes up out of the dirt, so you can plan on a cover just like someone with a sealed crawl space would.
How much does a crawl space vapor barrier cost in Atwater?
Across the US, putting in a crawl space vapor barrier usually costs about $1,200 to $4,000 per job, and that's the going rate nationally, not our price. An older cover that's mostly in one piece may only need a repair, which can keep yours lower. You'll get a written price after I've been under your house.
How thick should a crawl space vapor barrier be?
The usual guidance calls for plastic at least 6-mil thick, covering all of the ground or as close to it as the space reasonably allows. When you compare bids, ask each contractor how thick their plastic is, how much of the floor it'll cover and whether they fasten it up the walls and piers or stake it at the edges.
How do I get my crawl space ready for a vapor barrier?
Clear out whatever you've stored down there and any loose junk near the hatch, so the plastic can cover the whole floor. If something's too heavy or tucked too far back, point it out when I visit and we'll sort out what our crew moves.
Do you need a license to install a crawl space vapor barrier in California?
Anyone doing the job for more than $1,000, with workers, or on a job that needs a permit needs a California contractor's license. That's why it's worth asking anyone who bids on your crawl space for their license before they start.
What is the best way to seal and insulate a crawl space?
Fix the water first, because drainage and other moisture problems get handled before a vented crawl space is turned into a sealed, insulated one. A good ground cover is part of that first step, and once the space stays dry we can talk about crawl space insulation.
