How much does it cost to fix a ceiling leak in Toronto?
Most ceiling leaks in Toronto cost $500 to $4,000 or more to fix from start to finish, says Ultimate Mold Crew. That total has three parts: finding the leak, fixing the pipe, roof or flashing behind it, and drying and rebuilding the ceiling. A small leak below an upstairs bathroom that is caught early sits near $500 to $2,000.
| Scenario | Typical cost | Source |
|---|---|---|
| Ceiling water damage, inspection to repaint | $500 to $4,000+ | Ultimate Mold Crew |
| Small ceiling leak below an upstairs bathroom | $500 to $2,000 | Ultimate Mold Crew |
| Roof leak into attic and ceiling | $1,500 to $8,000+ | Ultimate Mold Crew |
| Long-term plumbing leak behind a wall or ceiling | $3,000 to $12,000+ | Ultimate Mold Crew |
Time is the biggest cost driver. A fresh supply-line leak may be dried and patched quickly, while a slow leak can soak insulation and framing and lead to demolition and mould work. Ultimate Mold Crew prices a long-term hidden leak at $3,000 to $12,000 or more, against $500 to $2,000 for one caught early.

How much does ceiling repair cost by size of damage?
A small brown stain with no soft drywall costs $300 to $700 to refinish and repaint, says Master Ceiling. Bubbling paint and a few soft spots, with some drywall replaced, cost $700 to $1,800. Sagging or mouldy ceilings that need new drywall and a full skim coat cost $1,800 to $4,500.
| Damage | Typical cost | Source |
|---|---|---|
| Small stain, no soft drywall, refinish and repaint | $300 to $700 | Master Ceiling |
| Medium patch, partial drywall replacement | $700 to $1,800 | Master Ceiling |
| Single ceiling section from a roof or plumbing leak (10 to 40 sq ft) | $400 to $1,200 | Toronto Drywall Pro |
| Medium water-damaged textured ceiling | $550 to $875 | Patch Dudes |
| Large textured ceiling repair | $1,300 to $2,025 | Patch Dudes |
| Sagging, mouldy or large section | $1,800 to $4,500 | Master Ceiling |
| Full room ceiling replacement | $3,500 to $7,000+ | Master Ceiling |
| Water-damaged drywall replacement | $4 to $9 per sq ft | Toronto Drywall Pro |
Textured and painted ceilings add cost. Patch Dudes says ceiling repairs cost about 15% more than similar wall repairs, and matching a texture adds about $85 to $525 or more. Its minimum drywall repair is $300 plus HST, and it does not fix the leak itself. For more drywall prices, see our drywall repair cost guide or compare drywall repair quotes in Toronto.
How much does it cost to find the source of a ceiling leak?
A leak detection visit in Toronto costs $250 to $500, and acoustic or moisture mapping $300 to $700, says Tornado Plumbing. It warns that water travels along framing, so a ceiling stain is often downstream of the real leak. Paying for detection first keeps the hole in your ceiling small.
| Service | Typical range | Source |
|---|---|---|
| Leak detection visit | $250 to $500 | Tornado Plumbing |
| Acoustic or moisture mapping | $300 to $700 | Tornado Plumbing |
| Hidden pipe repair, small opening | $400 to $1,200 | Tornado Plumbing |
| Water damage inspection or moisture assessment | $200 to $500 | Ultimate Mold Crew |
Tornado Plumbing names toilet flange or wax-ring leaks and failed soldered fittings as common causes of stained ceilings. If the stain sits under a shower or tub, our shower leak repair cost guide covers valve, grout and pan prices.
How much does it cost to fix a roof or flashing leak?
Roof leaks are billed by the roofer, not the ceiling contractor. Roofers Toronto prices counterflashing repair on one side of a chimney at $400 to $900 and a full chimney flashing replacement at $900 to $2,400. It says a ceiling stain near a chimney points to failed flashing most of the time.
| Repair | Typical cost | Source |
|---|---|---|
| Counterflashing repair, one side of a chimney | $400 to $900 | Roofers Toronto |
| Saddle cricket on a wide chimney | $400 to $1,200 | Roofers Toronto |
| Full chimney flashing replacement, all four sides | $900 to $2,400 | Roofers Toronto |
Roofers Toronto says face-caulked flashing repairs last 2 to 5 years before leaking again, while properly let-in counterflashing lasts 30 to 50 years. Ask any roofer how the flashing will be fixed. For vetted firms, see the best roofing companies in Toronto or compare roofing quotes in Toronto.
How much do drying and mould removal add?
If the ceiling cavity or insulation got wet, drying comes before any patching. Ultimate Mold Crew prices structural drying and dehumidification in Toronto at $1,000 to $3,500 and mould remediation after water damage at $1,500 to $6,000 or more. Toronto Drywall Pro says drywall that stays wet for more than 48 to 72 hours can grow mould behind the wall.
Do not repaint a stained ceiling until the source is fixed and the cavity is dry. Toronto Drywall Pro says repairs that skip the dry-out can fail. For larger losses, see our water damage restoration cost guide and water damage statistics, or compare water damage restoration quotes in Toronto.
Does insurance pay for a leaking ceiling?
Often, if the leak was sudden and accidental, such as a burst pipe or an appliance line failure. Master Ceiling says slow leaks are usually not covered. Ultimate Mold Crew says sudden damage may be treated differently from long-term seepage or neglected maintenance, so check your policy and deductible before you book the rebuild.
Photograph the stain and any active drip before cleanup, and keep the plumber's or roofer's written finding. Ultimate Mold Crew says most insurers expect homeowners to take reasonable steps to stop further damage, so do not wait on paperwork while water is still coming through.
How do you get an accurate ceiling leak quote?
Book the trade that matches the source first. A stain under a bathroom usually starts with a plumber, a stain near a chimney or exterior wall with a roofer, and a stain under an air handler with an HVAC tech. Send photos, say when the drip appears, and ask each firm whether its price includes drying and repaint.
