Crawl Space Encapsulation in Weaverville
Creek-side lots around Weaverville keep the dirt under a house damp, and the wet air it gives off rises into the rooms you live in. We do crawl space encapsulation so that musty smell fades and the air under your floor stays dry.
How do I get the humidity down under my house?
Close off the ground and the outside air, then dry what's left with a dehumidifier. We do it that way under most houses on damp lots near the creek. First we find out where your moisture comes from: the dirt, the vents, or water that stands after storms. Then we deal with each one, and the air under your floor stays dry.
Can I just run a dehumidifier down there and skip the rest?
You can, but on damp ground it'll run nearly nonstop and still fall behind. With bare dirt and open vents, it's trying to dry the soil below and the summer air outside along with your crawl space. Close those off first, and the same machine has just a small, closed-in space to dry, which it can keep up with.
The creek along the east edge of town
Reems Creek runs along the east edge of Weaverville, so plenty of houses here sit on ground close to the water. That ground stays damp long after the rain stops. Under your floor, the bare dirt breathes that moisture out as vapor, day and night.
You usually won't find a puddle down there, just air that feels heavy, smells like an old cellar and never quite dries out between storms. It builds so slowly that it's easy to miss for years.
Out the creek road toward Beech
If you drive Reems Creek road, the creek stays beside you out to the eastern end, where the historic Beech community sits. That puts a long string of houses on creek lots, not just the ones in town. If yours is out there, expect the same damp ground under it.
A lot of older houses along that stretch still breathe through open vents in the foundation wall. On a muggy summer day, outside air rolls in and meets ductwork the air conditioner has chilled. The ducts sweat, water drips onto the insulation, and the batts get heavy and sag.
What the damp does to the house above
You'll usually notice it upstairs long before anyone crawls underneath.
- A musty smell that's worst in the rooms over the crawl space, or right when the air conditioner kicks on.
- Ducts beaded with water, or a drip line on the plastic below them.
- Insulation sagging between the joists or lying on the dirt.
- Floorboards that cup or feel soft near an outside wall.
- Mold on the joists, which tells you the air is wet.
On a creek lot you're mostly fighting wet air, not a flood. So we'll talk with you about sealing the crawl space and a dehumidifier under the floor. If the batts are soaked or down, new insulation belongs in the plan, and where water does stand after a hard storm, getting that water out comes before we seal anything.
Frequently asked questions
Does a house that never floods still need work underneath?
Often it does, because standing water isn't the only way a crawl space gets wet. On damp ground by the creek, the dirt gives off moisture every day, and open vents let humid summer air in on top of it. If the floors smell musty or the ducts sweat, the crawl space is wet enough to matter, flood or no flood.
Will a sump pump dry out a crawl space that's only damp?
Not by itself. A sump pump only moves water that pools in a low spot, so it does nothing for wet air. On most creek lots from town out to Beech, the trouble is wet air, not standing water. A pump earns its place where water stands after storms. Where the ground is just damp, the job is sealing out the moisture and drying what's left in the air.
Why would sealing my crawl space cost more than a neighbor's?
The price follows the crawl space, not the street. A bigger space costs more, and so does one that's low and tight to work in. Old plastic, fallen insulation or junk to haul out adds work, and wet or damaged wood adds more. If we have to pump water out first or add a dehumidifier, that costs more than sealing alone.
