What should I do when a ceiling is dripping or bulging?
Stay out from under it, move people and valuables away, and stop the source if you safely can: close the water heater supply, switch off the A/C, or shut the main valve. Do not poke a bulge or turn on a light fixture that is wet. Call, take photos, and let a crew relieve the water.
A bulging ceiling can hold many gallons behind a thin skin of paint. Wet drywall and wet insulation are heavy, and the board can let go all at once, so keep your head, and everyone else's, out of the line of fall.
Put a bucket or a tarp under a drip, move rugs and electronics, and photograph the stain and the bulge before anything is moved. If water is dripping through a ceiling light, turn off that circuit at the breaker only if the panel is dry and you can reach it without stepping into water. If you cannot, stay out of the room and call.
Where does the water in a Mansfield ceiling usually come from?
It usually comes from above or beside the room: an attic water heater tank, a clogged AC condensate line or overflowing drain pan, a hail- or wind-damaged roof, or upstairs plumbing such as a laundry hose. The source sets the water category, and the category decides what is dried and what is removed.
In slab homes, equipment that a basement house would put underneath is often overhead. A failing tank heater in the attic soaks insulation before a stain ever shows below, and a clogged condensate line does the same in summer, when the air conditioner runs for weeks. See the pages on AC condensate leaks and water heater leaks.
Roofs are the other usual suspect. Hail and wind can open a path that does not show until the next rain, and the page on hail and roof leak water damage covers the tarping and the interior side. Upstairs bathrooms and laundry rooms are the last common cause. The crew traces the water before drying it, because a ceiling dried without finding the source simply gets wet again.
Can wet drywall and ceiling insulation be dried, or does it come out?
Drywall that stayed firm and was wet with clean water can sometimes be dried in place, but board that sagged, crumbled or took in dirty water is cut out. Wet insulation that has matted or held contaminated water is replaced. Moisture readings, not the look of the surface, decide each piece.
Drywall is gypsum between sheets of paper, and the paper wicks water sideways and upward. Once the board is soft, or the paper has separated, it will not recover and it can hold moisture against the joists. Insulation above the ceiling acts like a sponge, so in most jobs the wet portion comes out and new insulation goes in once everything above is dry. Humid Texas weather can stretch drying times.
You are asked before anything is removed, and the crew can document a section with photos and readings if you want your insurer to see it first.
Does a dry-looking ceiling mean the job is done?
No. A ceiling can look and feel dry while the drywall back, the insulation and the framing above are still wet. The EPA advises drying water-damaged materials within 24 to 48 hours, but that is a guideline, not a deadline, and mold may have started even where materials later dried.
Surface paint dries quickly and tells you little about the cavity. The crew compares the ceiling and framing with a dry reference reading from a part of your home that never got wet, and the job is complete when the numbers match.
If the ceiling stayed wet for days, ask for an assessment before the repair is closed up. Texas separates the people who inspect for mold from the people who remove it, so a mold inspection is a different role from mold remediation, and the same license holder may not do both on one project.
