A stained or sagging ceiling in Dearborn almost always means water arrived from above: an upstairs bathroom, a roof leak, or melting snow at the eave. Keep out from under a bulging area, shut off the source, and call. Dearborn Water Damage Restoration serves Wayne County 24/7 and a crew is dispatched as fast as one is available.
In a slab-on-grade market a wet ceiling is mostly a plumbing story. In Dearborn it is a house story. Much of the housing stock here is two-storey brick and frame built before the war, with a bathroom stacked over a kitchen, a laundry over a basement, and a roof that sheds a heavy Michigan snow load onto cold eaves. Water has a long way to travel before it shows on a ceiling, and by the time you see a brown ring it has already been through insulation, framing and the back of the ceiling finish.
What makes the job different in an older house is the finish itself. Many pre-1950 homes have plaster over wood lath rather than drywall, and plaster behaves badly when it is wet. It soaks water up like a sponge, it gets heavy, the keys that hold it through the gaps in the lath can let go, and a section can sag for days and then come down in one sheet. Drywall in newer additions and remodels swells and softens instead. A technician reads which one you have before deciding where to cut, what to protect and what has to come out.
Do not stand under a bulging or sagging ceiling, do not run a ceiling fan or light on a wet circuit, and do not paint over a stain, because the water source is still there. Switch off the room's breaker and call; a crew can open the ceiling from a safe angle.
Keep everyone out from under a bulging or sagging area, switch off the circuit for any light on the wet ceiling, and move furniture aside only if you can do it without standing beneath the damage.
The technician traces the wet area upward with a moisture meter and a thermal camera, checking the room above, the attic and the eave, because the stain is rarely under the leak.
If it is a plumbing leak the water is shut off and a licensed plumber is called for the repair; if it is roof or ice-dam water, the roof side is tarped or protected so the ceiling stops taking on more.
A sagging ceiling holds water above it. The crew opens the lowest point in a controlled way, catches the water and removes plaster or drywall that has lost its strength before it falls.
Air movers and dehumidifiers dry the joist bay, the insulation and the walls below, and readings are logged until the framing and finish materials are back to a dry reading.
Photos and moisture readings are recorded for your insurer. Patching, skim-coating or replastering, texture and paint are quoted separately as repair work.
Ceiling work is priced by the area affected and by how much of the floor and walls below also got wet. These published ranges are typical for Michigan and are not a quote.
| Job | Typical range | What it includes |
|---|---|---|
| Clean-water (Category 1) cleanup and dry-out | about $4 per sq ft | A supply-line or roof leak that has not sat long |
| Single room, clean water (Category 1) | $1,200-$3,200 | Cleanup and dry-out; excludes debris removal, repair and replacement |
| Typical Michigan water damage job | $1,300-$4,092 | A published Michigan figure, not specific to Dearborn |
| Water-damaged drywall repair after drying | a few dollars per sq ft | Repair after the dry-out; plaster work costs differently |
These are estimates for Wayne County in 2026, drawn from published Michigan ranges. Your exact price is explained and confirmed on site before any work starts, and repairs after drying are quoted separately.
A ceiling can stay wet or start dripping on a dry day because the water is coming from plumbing above, from snow melting slowly at the eave, or from insulation that soaked up a leak days ago and is still releasing it. A stain with no obvious weather link usually points to an upstairs supply or drain line.
In a two-storey house the bathroom is often right over the kitchen or dining room. A slow weep at a tub drain, a toilet supply or a shower valve can run along a joist and show up several feet away from the fixture. A technician starts by asking what sits directly above the stain and what is a few feet to either side of it.
Winter adds a second suspect. Warm air leaking into an attic melts the underside of the snow on the roof, the meltwater runs down to the cold eave and refreezes, and the ice then backs water up under the shingles. That water drips onto the top plate of the exterior wall and into the ceiling along the outside edge of the room, often days after the snow stops. The ice-dam roof leak service page covers that side in detail.
Because the cause changes the repair, take photos of the stain now, note the date, and note whether it grows after showers, laundry or thaw. That log helps the technician and your insurer.
Yes. Plaster over lath absorbs water, gets much heavier, and can sag and detach in a sheet because the plaster keys that grip the lath break when saturated. Drywall swells, softens and stains instead. Older Dearborn homes often have both, so each room is judged on its own.
Plaster is a layer of lime or gypsum pushed through gaps in wood lath so that it forms keys behind the strips. When water sits on top of it, the plaster gets heavy and the keys can snap. The ceiling may look nearly normal for a while, then bow, and then drop. That is why a bulging plaster ceiling is treated as a falling hazard rather than a stain.
Plaster also dries slowly, and the lath, the joists and the attic side behind it dry slowest of all. A ceiling that feels dry on the surface can still be wet inside. Moisture readings on the framing, not just on the finished face, tell the crew when a bay is truly dry.
Drywall is lighter and easier to cut out and replace, but it softens quickly and can grow mold if it stays wet. In a house with both materials, expect the crew to use different methods in different rooms. Replastering or skim-coating to match old plaster is a trade skill, so ask the repair contractor about it before a patch is quoted.
Do not puncture it while standing underneath. A bulge can hold a large weight of water and the surrounding plaster or drywall may fail the moment you open it. If water is actively dripping, a crew can open the lowest point from a safe position and catch the water in a controlled way.
People often hear that you should pierce a sagging ceiling to relieve the water. That advice is only safe if you can do it from the side, wearing eye protection and not under the sag, with a bucket ready, and with the circuit above shut off. In a plaster ceiling it is much riskier, because the whole panel may let go rather than just draining.
If you cannot stay clear, move people and pets out of the room, put a tarp or plastic sheet on the floor if that is possible without walking under the bulge, and call. A crew can carry the right protection and work from a ladder at an angle.
Whatever you do, do not turn on a ceiling fan or light fixture that is wet. Water inside a fixture box can reach live wiring.
Freeze-thaw weather is behind most winter ceiling stains here. Heat escaping into a cold attic melts snow, the meltwater refreezes at the eave, and the resulting ice dam forces water up under shingles and down into the ceiling. A burst or thawing pipe in an upper wall or attic is the other common cause.
Detroit-area winters bring roughly 130 nights a year at or below freezing and about 44 inches of snow in a normal year at Detroit Metro Airport, so the freeze-thaw cycle repeats often. Older houses with thin attic insulation and cold eaves are the ones that grow ice dams, and they leak at the outside wall first.
Pipes in exterior walls and cold attic corners can freeze and split above a ceiling; when the cold snap ends and the pipe thaws, water pours into the cavity. See the frozen pipe water damage page for how that call goes.
Either way the damage can go unseen for days because the attic is cold and nobody looks. A damp patch that appears after a thaw is worth a call even if it dries out, because the cause is still there.
Drying and removal are done by the restoration crew. Rebuilding the ceiling is separate repair work: in Michigan, residential repair work costing $600 or more needs a LARA-licensed Residential Builder or Maintenance and Alteration Contractor. You can look up any contractor's licence on LARA's lookup.
Once the cavity is dry, someone has to replace insulation, hang or plaster the ceiling, tape, texture and paint. That is rebuild work and is quoted on its own, after drying, so that you are not asked to approve a repair price before anyone knows how far the water went.
LARA exempts work whose total contract price is under $600 and requires a licence at $600 or more, and jobs may not be split to stay under it. Ask for the licence and look it up. Whether extraction and drying alone falls under the same licence is not something we state either way.
Plumbing and electrical fixes inside the ceiling need licensed trades and, in many cases, a permit from the city's building department.
Common in pre-1950 houses in east Dearborn and similar streets. Wet plaster is heavy, can pull away from the lath and drop, and is hard to match when patched. If the lath is sound, a section can sometimes be dried in place, but a ceiling that has sagged is usually taken down.
Found in newer homes and in rooms that were remodelled or finished. Drywall that stays wet loses strength and may sag in a few spots. Light staining on a ceiling that was only briefly damp can often be dried, while soft or sagging boards are cut out.
Spray textures and some older ceiling products in houses built before the 1980s may contain asbestos. Do not sand, scrape or drill suspect texture; ask the technician and check with the state before disturbing it.
Blown or batt insulation soaks up leak water and holds it against the ceiling, so a small roof leak can stain a large area. Wet insulation is usually removed and replaced rather than dried.
The houses where this call is most common are the two-storey brick and frame homes of east Dearborn and the older streets around Springwells Park, where bathrooms sit over finished rooms and the original plaster is still overhead. Newer remodels often add drywall under an old plaster ceiling in the next room, so one house can need two methods.
Heavy rain is the other trigger. Summer thunderstorms drive water sideways under shingles and flashing, and a wet ceiling after a storm is often a roof edge or chimney flashing problem rather than the sewer problem the rest of the neighbourhood is dealing with. A crew can check the roof edge and attic as part of the visit, but roof replacement is a roofer's job.
Because homes here have full basements, a ceiling leak can also keep going straight down: through the first-floor subfloor, into a finished basement ceiling, and finally to the floor drain. The visit looks at every level, not just the room with the stain.
A crew is dispatched as fast as one is available, and you approve the estimate before any work starts.

What drying a full Dearborn basement after a Category 3 sewer backup in the cold months involves, and what the readings must show.
An ice dam forms when heat escaping into the attic melts snow on the warm part of the roof, and the meltwater refreezes at the cold eave.
Do not wait. A sagging plaster ceiling can fall without warning, and wet drywall and insulation can start to grow mold. The EPA advises drying within 24 to 48 hours to limit mold, so call as soon as you see a stain and keep the room clear.
Not safely. Paint hides the ring but not the moisture. The stain returns, paint blisters, and any mold behind it keeps growing. A technician should confirm with readings that the cavity is dry before anything is repainted.
Coverage is decided by your insurer under your own policy. A standard homeowners policy often covers sudden and accidental damage, and usually does not cover a long-term leak. Take photos, stop the water if you safely can, and call your insurer early.
No. A ring can be an old stain from a leak that stopped. The way to tell is a moisture reading and a thermal scan. If the ring grows after rain, a shower, or a thaw, the leak is active.
Some houses built before the 1980s have asbestos in textured ceiling coatings or old joint compound, though many do not. Do not sand or scrape a suspect ceiling. Ask the technician and check with the state before disturbing it.
No. A crew can stop the spread, tarp a leak and dry the structure, but pipe repair is a plumber's job and roof repair is a roofer's. The crew's readings and photos help those trades and your insurer.
