Do you need a vapor barrier, a sealed crawl space or a water fix first?
Vapor barrier installation in Goose Creek means laying heavy plastic across the dirt floor of your crawl space and running it up the walls, columns and footings, so less ground moisture rises into the space under your floors. It often comes with fixing a drainage problem first, and sometimes with sealing and insulating the whole crawl space.
Most people call because the house smells musty, the floors feel cold or damp, or a service tech told them the plastic down there is torn or missing. The price turns on how big the crawl space is, whether water has to be fixed first, which plastic goes down and whether we stop at the ground cover or seal and insulate the space. The schedule turns on that same water work and on your pest company's timing. I'd rather tell you a ground cover is enough than sell you a sealed crawl space your house isn't ready for, and the estimate lists every area, material and prep step so you can see what you're paying for.
How do you know your crawl space needs a vapor barrier?
A musty smell inside
If the rooms over the crawl space smell like a damp basement, moisture from the dirt is usually rising into the space and coming up through the floor. Left alone, that damp air keeps working on the wood framing, and the smell settles into closets and carpet.
Bare dirt or torn plastic
When you open the access door and see bare ground, or old plastic bunched up in piles, the ground isn't covered anymore. As long as it stays that way, moisture has a straight path to the wood that holds up your floor.
Wet wood or puddles after rain
Water beading on the framing or ducts, or puddles after a storm, means the crawl space has a water problem as well as a vapor one. That gets fixed before new plastic goes down, because plastic laid over standing water just traps it.
Often done along with a vapor barrier
Attic air sealing
When the floors feel better but the upstairs still runs hot or drafty, the leaks are usually overhead, around the hatch, pipes and lights in the attic.
Retrofit insulation
If your house is older and the insulation already in place is thin or patchy, adding to what's there can help once the crawl space is dry.
How we install a vapor barrier
I start by looking for water, because plastic over a wet crawl space only hides the problem, so any drainage issue goes on the estimate as the first item. Once the ground is ready, we lay the plastic over every bit of dirt, run it up the walls, columns and footings, and overlap every seam so there's no strip of ground left open. Where we can, we fasten it to the walls so it doesn't slide down and leave a gap at the edge over time.
A ground cover handles moisture coming up from below, but it does nothing for the air leaking into your house from above, which is where attic air sealing comes in. In an older house, retrofit insulation adds to what's already in the walls or attic without tearing everything out.
Ground cover with the vents open
This suits a crawl space that stays dry and only needs the dirt covered. It's the smaller job, and the vents stay the way they are.
Sealed and insulated crawl space
This suits a house that keeps getting damp air through the vents, or one with ductwork running under the floor. It's more work because the vents get closed and the walls insulated, and any water problem has to be fixed before we start.
Reinforced plastic where people walk
This suits a crawl space with a furnace, water heater or ducts that a technician has to reach. Plain plastic tears under knees and boots, while thicker reinforced plastic holds up along those paths.

We're licensed and fully insured. That matters when a crew is working under your house, because you're not the one carrying the risk if something goes wrong down there.
Permits checked before we schedule
Before we schedule, we check with the office that handles permits for your address, since that can differ depending on where you live. In Goose Creek that's the City of Goose Creek, which takes permit requests through its portal and enforces the state's residential code and energy standard, and if a permit is needed, we take care of it and tell you where it stands.
What matters most on this job is handling the water before the plastic goes down, so tell us what's going on under your house and I'll come take a look.

Common questions
Does a crawl space vapor barrier help with radon?
It can help. A well-installed vapor barrier helps cut down soil gases such as radon along with ground moisture, which is why the plastic has to cover all the dirt and run up the walls with no gaps left open.
What is the best way to handle crawl space moisture in a humid climate?
Building scientists recommend an insulated, unvented crawl space in humid climates, because outside air coming through the vents can condense on cooler framing. Any water or drainage problem has to be fixed before the vents are closed, so that's the first step if you go this way.
How do I prepare my crawl space for a vapor barrier?
Empty out anything you've stored down there before we come, so the plastic can cover all the ground. We clear the loose debris that's left, and if you're not sure what can stay, ask me during the estimate.
How much does vapor barrier installation cost in Goose Creek?
The cost comes down to the size of your crawl space, any water fix it needs first, the plastic we use and whether you want a ground cover alone or a sealed, insulated crawl space. A ground cover with the vents left open is the smaller job, while reinforced plastic and sealing and insulating the space add material and labor. I give you the figure in writing after I measure.
How thick should a crawl space vapor barrier be?
Weatherization work specifications call for plastic at least 6 mil thick on crawl space ground, mil being the thousandths of an inch plastic sheeting is sold by. Ask each contractor what thickness they're quoting so you're comparing the same thing.
Will sealing my crawl space affect my termite treatment or pest warranty?
It can, so call your pest company before we start. Guidance on closed crawl spaces says to work with your pest professional so the system leaves their treatment and any warranty intact, and bringing them in early lets our work fit with theirs.
Get your crawl space looked at
Before you call, jot down any water you've seen after rain, what's stored down there and what equipment sits in the crawl space, so I can plan the visit around it.
