Crawl space vapor barrier in Jerome ID - a dry, covered floor under your house
Damp smell, cold floors or bare dirt under the house? We cover the ground so moisture and soil gases stay down there.
What a crawl space vapor barrier doesfor your Jerome house
If the floors over your crawl space run cold or the house smells a little musty, bare dirt under the house is a common cause. A crawl space vapor barrier is plastic laid over that soil to slow the moisture coming up and help keep soil gases out of your rooms, whether the crawl space is vented or not.
We start by looking for water, because plastic over a puddle just hides the puddle. Then we talk through a basic ground cover versus a fully sealed crawl space, what each one asks of you, and whether your walls or basement need vapor barrier installation too.
The price moves with the size of the crawl space, how much has to be cleared out, any water repair, and whether you want a basic cover or a sealed one. The schedule mostly turns on that water fix and the permit question. Your estimate lays out the plan for your house, with anything that needs fixing first at the top.
You can count on a straight answer about what your crawl space needs and what it doesn't, so call (208) 544-9045 to set up a visit.
Crawl space vapor barrier setups we install
The right setup depends on how dry your crawl space is, what runs through it and how often someone has to crawl around down there, so we match the plastic and sealing to that.
Basic ground cover
We lay plastic over the dirt and leave the vents open. It's the simpler setup, and it usually fits a crawl space that stays dry year round.
Fully sealed crawl space
We cover the floor, carry the plastic up the walls and piers, and close off the vents. It's more work up front and usually needs a dehumidifier to keep the air dry.
Heavier plastic for foot traffic
If plumbers or furnace techs crawl around down there, we suggest heavier plastic that holds up to knees and boots, because a torn barrier lets moisture right back through.

Licensed and insured, ask anytime
We're licensed and insured, and I'd rather you ask to see it before anyone goes under your house than wonder about it afterward.

I look at it with you
I go into the crawl space, take photos and show you what I found. Then I write up a plan that puts anything needing a fix at the top of the list.
Permits and prep
Once you say yes, we sort out the permit question with the right office and get any water handled first. Stored items and debris come out so the plastic can cover the whole floor.
Our crew lays the barrier
Our own installers lay and overlap the plastic across the floor. On a sealed crawl space they carry it up the walls and piers and close off the vents.
Cleanup and walkthrough
We clean up and go over the finished crawl space with you, photos and all, so you can see every seam and corner before we call it done.
Crawl space questions we hear
Is a basic vapor barrier enough for a crawl space in Jerome?
Often it is, as long as your crawl space stays dry. One publisher's guide says a basic barrier with the vents left open fits dry climates and tighter budgets, and Jerome County's building design criteria put this area in a dry climate zone inside the range that guide names. On a lot that drains well with no history of water trouble, the simpler setup may be all you need.
What is the best way to handle standing water in a crawl space before a vapor barrier?
Fix the water first, before any barrier goes in. The same publisher's guide puts standing water, puddles and water coming in at the front of the job, because plastic over a wet floor only covers the problem. If you've seen water down there, plan on that repair as step one.
How much does crawl space encapsulation cost in Idaho?
Full crawl space encapsulation with a vapor barrier and a dehumidifier usually runs about $5,000 to $8,500 per job in Idaho. That's the going rate for a fully sealed crawl space, not our price, and the size of the space, any water repair and how much has to be cleared out push it up or down. A basic ground cover is a smaller job, and your estimate gives the figure for your house.
How long does a crawl space vapor barrier last?
It depends mostly on how thick the plastic is and who crawls over it. One publisher's guide says thin 6-mil plastic punctures easily under a technician's knees, while a 20-mil product resists punctures and lasts 20 years or more. That's why we point people with regular service visits toward the heavier plastic.
Who has to register as a contractor to do this work in Idaho?
Idaho requires contractor registration for anyone taking a construction job over $2000.00, counting materials and labor together, unless they're exempt. Owners doing their own work on their own land, with no plan to sell within 12 months, are exempt. It's a fair question to ask anyone you're thinking of hiring.
How do I keep pipes in my crawl space from freezing in Jerome?
Sealing the crawl space instead of venting it can lower the risk of frozen pipes, according to a federal study of a sealed crawl space in New York. The same study found it can cut heating and cooling energy and ease summer moisture, though that house sat in a different region than ours. If pipes run down there or the floors above feel cold, sealing is worth weighing, and attic air sealing helps by stopping warm air from leaking out the top.
