A sagging ceiling is an emergency
A ceiling that sags or bulges is holding water in the drywall or in insulation behind it. Drywall is heavy when wet, and the paper face can tear. A ceiling that has dripped for days can come down, so people and furniture should stay out from under it.
If water is dripping, set a bucket below it and move belongings. If the light fixture is wet or flickering, leave that circuit off. Do not stand under a bubble of water, and call us before you open it.
Water near ceiling lights and fans
If water drips from a light fixture or a ceiling fan, turn off the switch and the breaker if you can reach the panel dry. Do not touch the fixture. If you smell burning or see sparks, call 911 and the utility before you call us.
Where ceiling water comes from
The stain on the ceiling is where water showed up, not where it started. Water moves along joists and pipes before it finds a spot to drip. Technicians trace the path from the stain back to the source with moisture meters and a thermal camera.
| Source above the ceiling. | Typical sign. | What the repair involves. |
|---|---|---|
| Roof leak through decking and insulation. | Stain after rain, often near a wall or vent. | Dry insulation and decking, then repair the roof and the ceiling. |
| Bathroom or kitchen above. | Stain under a tub, toilet or sink. | Plumber stops the leak, then dry the floor system and ceiling. |
| Supply or drain line in the joist space. | Spot that grows with use. | Open the ceiling, repair the line, dry the cavity. |
| HVAC in the attic. | Staining near air handlers or ducts. | Clear the condensate path, dry insulation, patch the ceiling. |
Roof leaks that show up as ceiling damage
Water damage from a leaking roof appears indoors long before anyone climbs up to look. Rain enters through flashing, a lifted shingle or a failed seal, runs along the underlayment and soaks insulation. The ceiling is the last layer to show it, and by then the attic framing may be wet too.
A roofer repairs the roof, and we handle the damage inside. If you have both a roof problem and active storm damage, see storm water damage for how wind and rain openings are handled. Do not wait for a dry day to call, because trapped moisture does not drain on its own.
Baltimore County says building permits are required for additions, alterations and structural modifications to existing dwellings. Ask whether the repair you are planning triggers one, particularly if framing is replaced.
Repair options and trade-offs
- Stain only, ceiling dry: stain-blocking primer and paint can finish the job.
- Wet drywall but sound: dry in place with equipment if readings allow.
- Sagging or soft drywall: cut out and replace the damaged section.
- Wet insulation above: remove and replace, because it holds water against the framing.
- Old stain with no moisture: confirm it is dry with a meter, then repaint.
Painting over a stain that is still damp traps moisture and the stain returns. Ask for a meter reading before any repainting. For a structure that stays damp, structural drying is the process that pulls the moisture out.
Wet ceilings and the insulation above them are dried and verified under the ANSI/IICRC S500 approach of measuring moisture, not judging by touch. A reading after the repair confirms nothing wet is sealed in.
Water above the ceiling?
Call the 24/7 line. A crew can locate the wet area before the ceiling gives way.
Old Catonsville ceilings
The Old Catonsville Historic District includes houses built between 1866 and 1950, and many older homes have plaster ceilings instead of drywall. Plaster is heavy and cracks when wet, and a failing plaster ceiling can fall in pieces. If you have plaster, mention it on the first call so the crew can plan the right protection and repair.
Cost and insurance for a wet ceiling
- How large an area is wet and whether the ceiling must be removed.
- The source and whether insulation and framing are wet.
- Ceiling type, since plaster repair differs from drywall repair.
- Drying time and equipment.
- Paint, texture and finish work after repair.
Sudden and accidental water damage is often covered by homeowners insurance, and gradual leaks often are not. Check your policy and ask your insurer. We explain the scope and the price before work starts, and you can call the line for a real number.
Common questions
Yes. A ceiling can sag any time after a storm or a plumbing failure, and the line is answered 24 hours a day. Move people from under the area and call so a same-day response can be planned when a crew is available.
Not unless you are prepared for the water to come out. Place a bucket and a tarp under it first, wear eye protection and keep people away. Calling us first is safer, because a crew can relieve it in a controlled way.
Only if it is verified dry. Painting over a damp ceiling traps moisture and the stain returns. A technician checks with a moisture meter before any primer or paint goes on.
It depends on the cause and your policy. Sudden storm damage is often handled differently from a long-term leak. Ask your insurer, and keep photos of the roof, the stain and any wet insulation.
A moisture meter and a thermal camera show whether materials are still wet or drying. If readings rise after rain or after a fixture is used, the source is still active and must be found before repairs.
