Crawl Space Encapsulation Around Fletcher
Fletcher sits on level ground threaded with creeks, so rain soaks in instead of running off and the dirt under your house stays wet. Crawl space encapsulation in Fletcher seals that damp off and keeps the floor above it dry.
Why does the dirt stay wet under a house on flat ground?
Flat ground gives rain nowhere to run, so it soaks in beside the foundation and wets the dirt underneath. That moisture rises off the dirt into the crawl space air. On a low lot near Cane Creek, the ground rarely dries out between storms. Over time that damp air pulls the insulation down from the joists, and the rooms above start to smell musty.
Should the yard or the crawl space get fixed first?
Fix the outside water first if rain runs toward the house, then deal with the crawl space. A sealed crawl space lasts longer once the gutters, downspouts and grade carry water away from the foundation. If the yard drains fine and the dirt is only damp, we go straight to the crawl space and keep it dry.
Level ground that holds the rain
Rain here tends to sit where it lands. Most of Fletcher is flat, with hills only in places, and Cane Creek, the French Broad River and their tributaries run all through it.
On a flat lot near one of those creeks, rain has no slope to run down. It soaks in along your foundation wall and keeps the dirt under the house wet for days.
Big storms make it worse. During Helene, the French Broad River in Fletcher crested ten feet higher than its previous peak. When the creeks and the river run that high, rain on flat ground has nowhere to go, so it pools in the yard, pushes on the block foundation and finds the low corner of your crawl space.
If that happens after every heavy rain, water removal and waterproofing come first. We don't seal anything down over wet dirt.
Subdivision houses still on the builder's first plastic
Fletcher grew fast from roughly 1980 through 2000, as developers built multiple large subdivisions. If your house went up then, the plastic on the dirt may still be the builder's. So may the insulation batts between the floor joists. Decades of damp air off wet ground wear both of them out.
The plastic tears, slides off the walls or bunches up until bare dirt shows. The batts soak up moisture, get heavy and sag, and some end up lying on the dirt. Upstairs, you'll notice a musty smell that's worst in summer, or floors that stay cold all winter.
Damp dirt may only need a new vapor barrier, while dirt that never dries out calls for sealing the whole crawl space. Once we've been under your house, we'll tell you which one it needs.
Where the water comes from decides who pays
If stormwater on your property threatens your home, the Town of Fletcher offers grants that can help pay for the drainage outside. That's the grading, ditches and pipes that turn water away before it ever gets to the crawl space.
After the next heavy rain, step outside and watch the water heading for your house. Is it running off the road or out of a ditch, or off your own yard?
Road and ditch water is the kind of stormwater problem the grants are set up for, so it's worth asking the Town about. Water off your own roof or yard usually means gutters and grading that are yours to fix. The answer also tells us where to start in the crawl space.
Frequently asked questions
Is it worth sealing a crawl space that's damp but never floods?
Usually, yes. Damp does its damage slowly, and wet dirt on a level lot keeps the air under your floor humid all summer. That air sags the batts, sweats on the ductwork and leaves a musty smell upstairs. Sealing costs more than new plastic alone, so we check how wet the dirt, the air and the framing are first. Then we'll tell you if the smaller fix will hold.
Do I need a sump pump under my house?
Only if water actually collects down there. Damp dirt doesn't need one. Puddles that stand in the low corner after a heavy rain do, because that water has to have a way out before we seal anything over it. We see both kinds on the soggy lots along Cane Creek, and we only put a pump where water stands.
How do I know my old ground cover needs replacing?
It's worn out once it stops covering the dirt. That means plastic that's torn, bunched up or pulled away from the walls, bare dirt showing through, or water sitting on top of it. Plenty of houses still have the plastic that went down when they were built. If yours is that old and the batts above it sag or smell musty, damp has been getting through for a while.
