Drywall, Walls & Ceilings

Ceiling Repair in Ontario

Ceiling damage is the one repair people rightly treat as urgent. A spreading brown stain, a sag, or a bulge that looks like it's holding something usually means water from above β€” a roof leak, an overflowed tub, a sweating pipe, or a failed washing machine hose in the room upstairs. The ceiling is the symptom; something above it is the cause, and the cause gets found before the cosmetics start.

Once the source is dead, the repair depends on what the water did. A dried stain on sound drywall needs stain-blocking primer and paint. Soft, sagging or crumbling board gets cut back to solid material and replaced β€” wet drywall doesn't recover its strength, and insulation above it may need replacing too, since soaked insulation stays wet and grows problems. If a bulge is visibly holding water, don't wait for a quote: put a bucket down and poke a small drain hole, because a controlled drip beats a collapse.

Not all ceiling work is water, of course. We also fix settlement cracks, seam lines that have let go, holes from light-fixture changes, and the dents and gouges of everyday life. Send photos β€” of the ceiling and, if you can, of whatever sits above it β€” for a free quote.

What this covers

  • Water-damaged ceiling repair and replacement
  • Help identifying the source of the leak
  • Cutting back and replacing damaged board
  • Wet insulation removal and replacement
  • Crack and seam repair, properly taped
  • Sagging ceiling refastening
  • Holes from fixtures, fans and access cuts
  • Texture matching, including stippled finishes
  • Stain-blocking primer and repainting

What affects the price

  • Size of the damaged area β€” a patch versus replacing whole sheets
  • Whether the leak source still needs finding and fixing first
  • Wet insulation above the ceiling that needs replacing
  • Texture matching; smooth ceilings and stippled ceilings finish differently
  • Ceiling height and access β€” stairwells and vaulted areas need staging
  • Drying time: a soaked cavity has to dry before it's sealed up
  • Repainting patch-only versus the whole ceiling for a uniform finish

Every home is different, so we don’t publish flat prices β€” the quote is free and based on your actual job.

Common questions

There's a bulge in my ceiling that looks full of water. What do I do right now?
Put a bucket under it and poke a small hole in the centre of the bulge with a screwdriver to let it drain. It feels wrong, but a controlled drain through one small hole does far less damage than the ceiling letting go at once. Then shut off whatever's feeding it β€” water main if you're not sure β€” and get the source fixed.
The stain is dry and hasn't grown in months. Can it just be painted?
If the board is sound β€” no softness, no sag β€” then stain-blocking primer plus paint is the whole job. The primer matters: water stains bleed straight through regular paint, which is why painted-over stains reappear. If the board flexes when pressed, it's replacement, not paint.
Do you fix the leak too, or just the ceiling?
The platform covers both sides. Plumbing sources go to licensed plumbers, roof leaks to roofers, and the ceiling repair follows once the source is confirmed dead. What we won't do is close up a ceiling under an unfixed leak β€” that's a repair with an expiry date.
Part of my ceiling is sagging but there's no water stain. What causes that?
Commonly, fasteners letting go β€” older ceilings were sometimes nailed rather than screwed, and nails work loose over decades. Heavy attic insulation, humidity cycles, or board installed parallel to joists can contribute. Refastening with screws and re-finishing usually cures it; we'll check whether anything above is adding weight it shouldn't.
My ceiling has that stippled texture. Can a patch match it?
It can get close enough that guests will never spot it, though texture matching is part craft and part experiment β€” a test patch gets sprayed or trowelled and adjusted before the real one. One flag: if your home predates the early 1990s, textured coatings should be tested for asbestos before anyone sands or scrapes them. That's a lab test first, not a judgment call.
