/crawlspace-waterproofing Sealing the crawlspace so the damp under your house stops feeding mold, musty air and cupped floors in the rooms above it.
Air does not stay put. It rises from the crawlspace into the living space through every gap in the subfloor, carrying whatever is down there with it. A bare dirt crawlspace evaporates moisture into that air continuously, and the rooms above pay for it.
That is why the symptoms usually show up upstairs first. Musty smell, cupped hardwood, allergies that get worse indoors, an HVAC system working harder than it should to move damp air.
A durable vapor barrier sealed across the floor and up the walls, with the seams and penetrations taped rather than just laid loose. Drainage and a pump if the space takes standing water. A dehumidifier where the air needs conditioning as well as separating.
Done properly it is a sealed system, not a sheet of plastic. Done improperly it traps moisture against framing, which is worse than leaving it alone.
It means sealing the crawlspace off from the bare ground: a heavy vapor barrier across the floor and up the walls, with the seams taped and the penetrations sealed. It matters because the air down there does not stay down there. It rises into the house through every gap in the subfloor and brings the damp with it. That is why the first signs usually show up upstairs, as a musty smell, cupped hardwood, or a furnace working harder than it should.
White chalky residue on block, a musty smell that never clears, cracks that keep growing, rust at the base of appliances, damp patches that darken a day or two after rain, and humidity you can feel. Any sign of water damage or mold is worth an inspection before it becomes structural.
Anywhere from three days to a week, depending on the scope of work and site conditions. You will get a specific timeline with your written scope rather than a guess over the phone.
