The first question on a ceiling water damage call is not where the water came from. It is whether that ceiling is wet right now. A good share of the stains we get asked to look at in Liberty Hill are history: a roof detail fixed two owners back, a condensate line somebody cleared years ago, a ring rolled over with flat white before the house changed hands. A dry stain is a painter's job. A wet one is ours, and the difference is a number on a meter, not an opinion from the floor.
So we read it first. A pin meter through the paint, a non-invasive scan across the whole plane instead of the discolored part, and a thermal camera to see whether the cool area has an edge that matches the stain or runs well past it. Live water usually spreads further than the mark, because drywall stains where it dries and stays clean where it is still soaking. Old damage reads the other way: the ring is the whole story, the board is stiff, the tape is still bonded. Nail pops, a soft spot under thumb pressure, and a sag that holds a fingerprint mean the board is carrying weight and the work starts today.
What happens once the meter says it is live
We find and stop the source before anything gets opened, since a ceiling cut under a running leak just gets wet again. From there it goes in order. Any sag gets drained in a controlled stream rather than left to let go over the furniture. The board comes back to the joist where the readings turn dry, the soaked batt comes out of the bay, and the framing and the top plate below it get air movers and a dehumidifier, with numbers taken every day. New board goes up after the wood is dry, the texture is matched to the rest of the plane, and the patch is sealed so nothing bleeds through the new paint a month later.
- A meter and a thermal scan across the whole ceiling, not just the stained part
- A straight answer when the readings say the stain is old and dry
- Soaked insulation out of the bay and the framing dried to a number
- Board, matched texture, and a stain-blocking sealer so the ring stays gone

If the readings come back dry, that is the answer, and what you have is a paint job rather than a ceiling repair. If they come back wet, water is sitting on the back of that board and it does not improve while anyone thinks it over.
