Wet Drywall and Walls in Prosper, TX

Wet walls in Prosper rarely stay a small problem. Most homes sit on slab-on-grade foundations, so when water spreads across a tile or carpeted floor it meets the bottom of every wall in its path and starts wicking up the drywall. On interior walls the paper face and gypsum core pull water upward several inches; on exterior walls the batt insulation inside the cavity holds it against the board. In a hot, humid North Texas summer the wall cavity stays warm, which slows natural drying and speeds up swelling, staining and the risk of mold growing behind the paint.

At one hour water is sitting at the bottom plate and soaking the lowest inch or two of drywall. By 24 hours it has usually wicked well above the baseboard, the baseboard has swollen and the paint shows a faint line. Between 24 and 48 hours, the wet gypsum behind a painted wall becomes a place mold can start, even though the room looks fine. After a week, drywall that could have been dried often has to be flood cut, and the bottom plate and insulation may need to be opened as well.

Drywall wet with clean water from a supply line, a dishwasher or a water heater can often be dried in place when it is still firm and the crew starts within the first day or two. Interior walls without insulation dry well with air movers set along the wall and small holes drilled behind the baseboard line to push dry air into the cavity. Studs and the bottom plate on the slab are checked separately, since wood and concrete hold water longer than gypsum. Walls with one or two coats of latex paint dry better than walls covered in heavy wallpaper or vinyl.

A flood cut, a clean line a little above the highest wet reading, is the standard answer when the board is soft, when water wicked high, or when the water was category 2 or 3, such as a washer drain, toilet overflow or storm water. Wet batt insulation in exterior walls has to come out because it holds water against the studs. Moisture resistant board behind tubs and laundry boxes is checked closely, and the wall behind a kitchen sink base often needs the cabinet pulled so the drywall behind it can dry.

Across Prosper, wet wall calls tend to follow the floor plan. In Star Trail and Windsong Ranch, an upstairs laundry or bathroom leak can run inside a wall from the second floor to the first, while a slab leak or a failed dishwasher line in the Lakes of Prosper or Tanners Mill tends to wet the lower part of kitchen and hallway walls. Homes along irrigated HOA lawns sometimes see a garage or exterior wall wicked from outside when a sprinkler valve or line breaks and water pools against the foundation.

Homeowners in Celina, Little Elm and Aubrey call about the same thing, especially in new two-story homes where drywall meets a slab in every room downstairs. In Little Elm, storm water from heavy spring rain adds to the list, and Aubrey homes on rural acreage can see walls wet from a frozen line in a garage or workshop. One call connects you with a local restoration pro serving your town who measures, cuts and dries the walls.
