Water Stains From Roof and Plumbing Leaks
Source first, then cut back to dry board, then seal with a stain-blocking primer. Paint over a water stain always bleeds back. See water damage drywall repair.
Ceilings are the hardest surface in a home to repair invisibly, and it is work Kingston Drywall does every week. We fix water stains, cracks, sagging board and failing plaster ceilings for homeowners and landlords across Kingston and the surrounding towns.
More than 20 years on the tools has taught us that ceiling problems usually have a cause above them: a leak, truss movement or undersized board. We fix the cause first, then the surface.
We are licensed, insured and WSIB covered, and we protect your room before any cutting starts. The finished ceiling is primed and ready for paint.
Light from windows and fixtures rakes across a ceiling at a low angle. That exposes every high spot and edge a wall repair would get away with.
Texture is harder to match overhead, and gravity works against every patch. A ceiling repair needs wider feathering, better backing and more careful sanding than the same repair on a wall.
That is why we treat ceilings as a specialty, not an afterthought.

Usually 1/2 in. board on joists 24 in. apart, or an old adhesive-and-nail install that has let go. Mild sags can be re-screwed; badly bellied board is replaced with 5/8 in. or sag-resistant ceiling board.
Cracks along the wall-ceiling junction are often truss uplift, common in Kingston subdivisions built from the 1980s to the 2000s. We refasten and finish the corner so it can move without cracking.
Small surface areas are cut out and rebuilt. Larger growth or mould spreading between joists needs a professional remediation contractor first, and we will tell you plainly which you have.
Common in Kingston's pre-1940 homes. We re-anchor loose plaster with plaster washers, then skim coat, or board over when the ceiling is beyond saving.
Openings from removed fixtures, fans and track lighting are backed, plugged and feathered so the ceiling reads as one surface.

Kingston ceilings carry every texture: sprayed stipple, knockdown, hand swirl and smooth. We match them on a test board before touching the repair.
Sometimes a patch will never blend, because the old texture has yellowed or the damaged area is large. In that case we will recommend re-skimming or re-texturing the whole ceiling, and explain why that is the better value.
Prefer a smooth ceiling? Our popcorn ceiling removal service can take the texture off while we repair.
Ceiling repairs are banded by the size of the damage. Two things change the price more than anything else: whether the ceiling is textured and whether the room has to be emptied.
| Damage band | Typical scope |
|---|---|
| Minor | Hairline cracks, a small stain, one fixture hole |
| Moderate | Several cracks, a stained section cut back and replaced |
| Major | A sagging ceiling re-secured or large sections replaced |
| Full ceiling | Whole ceiling replaced or boarded over and finished |
After a major leak, a restoration company usually extracts water and runs drying equipment first. We come in once the framing and remaining board read dry.
We document the ceiling for your adjuster with photos and moisture readings, then rebuild, texture and prime. If insulation above the ceiling was soaked, it gets replaced before we close up.
Our insulation and drywall crew handles that step, so one trade finishes the whole assembly.
Straight answers to the questions we hear on site visits every week.
It depends on the size of the damage, whether the ceiling is textured and whether the room needs emptying. Send photos and we can usually give you a range before visiting.
Most can be patched. We cut out the wet and stained section back to sound board and replace just that area. The whole ceiling only comes down when the damage is widespread or the board is sagging throughout.
We take moisture readings on the board and framing before we close anything up, and we confirm the repair with the roofer or plumber who fixed the source.
We test the stipple on scrap board and match the aggregate size and pattern. On older or painted stipple we will tell you honestly how close the match will be.
It can be. A ceiling that is bellied, cracked along a seam or heavy with water can drop without warning. Keep people out of the room and call us, or a plumber first if the sag is holding water.
Yes. We stabilise lath and plaster ceilings with plaster washers, repair cracks with setting compound and skim coat or board over where needed. See plaster repair.
Smaller wall damage is covered on our drywall repair page, and noisy ceilings under living space can be improved with drywall soundproofing.
We repair ceilings well beyond the city, including cottage and village homes around Gananoque and lakefront houses near Sydenham.
Send photos of the damage and a wider shot of the ceiling, and tell us whether the leak has been fixed. We will reply with next steps and a visit time.
