What does a brown stain on my ceiling mean?
It means water has been through the ceiling from above — a pipe, a roof leak, an upstairs bathroom, or an AC unit. Water has usually been there longer than the stain, because drywall discolors only after repeated wetting. The source is not always directly above the stain; water travels along joists and pipes before it drips.
How do I know if it is still leaking?
A stain that grows, feels damp or soft, or comes back after rain or after a bath or shower runs is an active problem. A stain that stays dry and the same size may be an old, fixed leak. If you are unsure, call (000) 000-0000 and describe what you see.
My shower or tub has a slow hidden leak. What should I do?
This is the most common call in this category: a shower valve or tub drain leaking slowly behind the wall. Signs are soft or spongy drywall at the base of the shower or tub wall, loose or lifting tiles, grout that keeps cracking in the same spot, or a musty smell localized to one bathroom. Because it is slow, this leak class often has mold established before it is found. A technician confirms it with moisture readings and, if needed, a small inspection opening behind the fixture.
Should I repair the stain now, or dry first?
Dry first. Painting or patching over a wet ceiling traps moisture and the stain usually comes back, sometimes with worse damage behind it. Drying and source repair come first; cosmetic repair is the last step.
Does a ceiling stain always mean my drywall has to come out?
No. Drywall that is caught early and dried properly can often stay. Drywall that is soaked through, sagging, soft or contaminated needs to be removed. The moisture readings and a hand pressing the surface tell the story.
How long does a ceiling take to dry?
Most ceilings dry within the normal 3–5 day range once the source is stopped. Thick insulation above the ceiling can hold water and stretch the timeline. Readings taken in the ceiling cavity decide the end point.
Is a wet ceiling dangerous?
Water adds weight, and heavily soaked drywall can sag or come down — keep people, especially children, out from under a bulging ceiling. Water near light fittings and wiring is the other reason to treat a wet ceiling seriously and keep the power to that area off until it is checked.
Local facts
- Southlake attic AC units sit above ceilings — ceiling stains in summer are often the AC, not the roof.
- Upstairs bathrooms over kitchens and living rooms are a common source pattern in two-story Southlake homes.
- Water travels along joists and pipes — the stain is not always under the source.
