Crawl space vapor barrier in Sugar Land TX - dry framing under your floors

Most people call because the floors feel cold or damp, the house smells musty, or someone looked under there and saw wet dirt and torn plastic. The price turns on how big the space is, how many piers the sheet has to wrap, how far the space sits above or below the ground outside, how odd the foundation shape is, and whether you keep the vents or seal the space, which adds drying equipment. The schedule mostly turns on what's down there already, because anything wet or rotten gets fixed before plastic goes in. The estimate lists the steps we plan, in order, so you can see what comes first and why.

I start by going under the house to see what we're dealing with. Standing water, mold, rotten wood or anything hazardous gets handled first, because plastic laid over a wet problem just hides it. If you have a pest company, we check with them before we lay anything down, so the barrier doesn't get in the way of their treatment. If you're thinking of closing off the vents, we look for fuel-burning equipment down there first, because a sealed space is a bigger job than plastic and vent covers. Then our installers lay the sheet over the soil and overlap the seams. The usual guidance is to cover the whole floor, or as close as you can reasonably get, and carry the plastic up the walls, piers and footings.

Crawl space work often ties into the rest of the house. If you need plastic somewhere other than under the floor, that's our vapor barrier installation work. And because air pulled up from below has to escape somewhere, attic air sealing closes the gaps at the top of the house where it leaks out.

Whether a vapor barrier alone needs a permit in Sugar Land is something we check for your address, not something I'll assume. The city's Permits Office handles permits here, weekdays 8 a.m. to 5 p.m. at 281-275-2270. If your job needs one, we apply for it and keep you posted on inspections. If your house is in the floodplain, look up its flood zone first on the city's floodplain map, because the city says substantial renovation usually calls for flood damage protection. When a house gets raised, the enclosed area underneath often ends up below flood level, where flood vents and water resistant materials become necessary. If you need the zone confirmed in writing, the City Engineer takes email requests for a letter from the city's floodplain administrator.

Under houses around here we usually find old plastic torn along the path to the AC or the plumbing, or bare dirt with nothing on it at all. We see the same thing on jobs in Stafford and Missouri City, so we plan the sheet around the spots someone will crawl to later.
