Quick Answer: What Does Water Damage Repair Cost in Toronto?
If you just want numbers: water damage repairs in Toronto run $450 to $3,000+ depending on the size and severity. A single ceiling stain from a resolved leak? $450-$800. A full wall section with bubbling, wet drywall, and mould? $1,800-$3,000+. Most jobs we see fall in the $800-$1,500 range — that covers removal, drywall replacement, stain-blocking primer, and two topcoats of paint.

Types of Water Damage We Repair
Ceiling Stains
The most common call we get. You look up and there's a yellow-brown ring on your ceiling. Sometimes it's from a one-time event — a toilet overflow upstairs, an ice dam last winter — and sometimes it's an ongoing slow leak.
If the stain is dry and the source is fixed, this is a straightforward repair. We cut out the damaged section, patch with new drywall, apply Zinsser BIN shellac primer to block the stain permanently, and paint to match. If your ceiling is textured, we match the texture before painting.
The biggest mistake I see? People slapping a coat of Kilz over the stain and calling it done. That works for about three months. Then the stain bleeds right back through. If the drywall is soft or crumbling when you press on it, it needs to come out — no amount of primer saves saturated drywall.
Wall Bubbling and Peeling
When water gets behind your wall paint, the paint film loses adhesion and starts to bubble, crack, and peel. This is more than cosmetic — it means moisture is trapped in the wall cavity.
We remove the damaged section, check for mould behind the drywall, verify the area is dry with a moisture meter, and then rebuild. If the insulation is wet, it comes out too. Wet insulation is dead insulation — it loses its R-value and becomes a mould factory.
This is a common issue in Toronto bathrooms where ventilation is poor and moisture builds up over time.
Mould Damage
Let me be upfront: we handle surface-level mould on drywall. If you've got mould covering more than about 10 square feet, or if it's behind walls in the framing, you need a certified mould remediation company first. We'll tell you honestly if a job is beyond our scope.
For contained mould on drywall surfaces, we remove the affected drywall entirely — you can't just clean mould off drywall and paint over it. The mould roots penetrate into the paper facing. We cut it out, treat the surrounding area, install new drywall, and seal everything with shellac primer.
Our Assessment and Repair Process
Here's exactly how a water damage repair works with us:
Step 1: Assessment — We come out, look at the damage, and check moisture levels with a meter. If the area is still wet, we stop here and tell you to address the source first. No point repairing something that's going to get damaged again next week.
Step 2: Removal — We carefully cut out the damaged drywall, going beyond the visible damage to find dry, solid material. We check behind the wall for mould, wet insulation, or structural issues. If we find something unexpected, we call you before proceeding.
Step 3: Drying — If there's any remaining moisture, we let it dry completely. This might mean waiting a day or two. I know that's frustrating, but sealing in moisture is how you end up with a mould problem six months later.
Step 4: Rebuild — New insulation if needed, new drywall, taped and mudded seams. Multiple thin coats of compound with proper drying between each. This is drywall repair at its core, and it's where experience matters most.
Step 5: Prime and Paint — Shellac-based stain-blocking primer on the entire repaired area, then two topcoats of paint matched to your existing wall colour. If your walls haven't been painted in years and the colour has shifted, we may recommend painting the full wall for a seamless result. We offer complete interior painting if that's the route you want to go.
When to Call Us vs. a Plumber
This is something I get asked constantly, so let me make it simple:
Call a plumber first if:
- You have active water dripping or flowing
- You can see a pipe leaking
- Multiple areas are affected at the same time
- The water stain is growing or getting worse
Call us when:
- The leak source has been identified and fixed
- The area is dry (or nearly dry)
- You need the cosmetic and structural drywall repair
- You want the stain sealed and painted properly
If you're not sure, call us anyway. We'll assess the damage and tell you whether you need a plumber, roofer, or both before we can start. I'd rather send you to the right person first than do a repair that fails in two months.
Stain-Blocking Primers: Why They Matter
Not all primers are created equal when it comes to water stains. Here's what I've learned after 20+ years:
Shellac-based (Zinsser BIN) — The gold standard. Blocks water stains, tannin bleed, smoke, and odours. Dries in under an hour. The only primer I use for water damage work. Yes, it smells strong during application, but it works permanently.
Oil-based (Kilz Original, Zinsser Cover Stain) — Decent for mild stains. Not reliable enough for serious water damage. I've seen too many callbacks from painters who used oil-based primers on water stains.
Latex-based stain blockers — Fine for minor scuffs and light stains. Completely inadequate for water damage. Don't let anyone tell you otherwise.
The primer is the most critical step in the entire repair. Skip it or use the wrong product, and you're doing the whole job again in six months.
Toronto-Specific Water Damage Issues
After 20 years of working in Toronto homes, here are the water damage patterns I see over and over:
Condo Leaks
Toronto condo owners deal with water damage more than anyone. The neighbour upstairs has a slow dishwasher leak, the building's HVAC system drips condensation, the unit above has a bathroom flood — and it all ends up on your ceiling. We repair condo water damage regularly and know how to document everything for your property management company or insurance claim.
Ice Dams
Toronto's freeze-thaw cycles are brutal on older homes. Ice builds up at the roof edge, water backs up under the shingles, and next thing you know, your bedroom ceiling has a stain. We see a wave of these calls every March and April once things start to thaw. The damage often shows up in bedrooms along exterior walls and in attic-adjacent ceilings. The roof needs to be addressed first — usually by a roofer improving ventilation or adding ice and water shield — but once it is, we'll remove the damaged drywall, treat the area, and make your ceiling look like nothing ever happened.
Basement Seepage
Foundation cracks, poor grading, failed weeping tile — basement water damage is a Toronto classic. The walls get damp, the paint peels, and mould starts creeping in. We handle the interior repair — removing damaged drywall, treating surface mould, rebuilding and painting. For the actual waterproofing, you'll need a foundation specialist. We can handle the foundation parging on the exterior if that's part of the issue.
Bathroom Moisture Damage
Poor ventilation in Toronto bathrooms — especially in older homes and condos — leads to chronic moisture buildup. The paint peels, the ceiling gets soft, and eventually you've got mould. A proper bathroom paint job with moisture-resistant paint and a working exhaust fan prevents this. But if the damage is already done, we'll strip it back and do it right.
Insurance Considerations
A few things I've learned from working with Toronto homeowners on insurance claims:
- Document everything before you touch anything. Take photos of the damage, the source of the leak, and any affected belongings.
- Sudden vs. gradual — insurance typically covers sudden, accidental damage (burst pipe, appliance failure). Gradual damage from a leak you knew about? Usually denied.
- Get multiple quotes — your insurance company may want to compare. We provide detailed, itemized quotes that break down materials and labour.
- We're not adjusters — we can provide documentation and photos of our work, but the claim process is between you and your insurer. We're happy to answer any questions they have about the scope of work.
- Don't wait — some policies require you to mitigate damage promptly. Leaving a wet ceiling for weeks while you figure out insurance could give them a reason to deny your claim.
Signs You Shouldn't Ignore
Don't wait on these — they all indicate active or worsening water damage:
- Recurring stains that come back after painting — the leak isn't fixed
- Musty smell in a room, even if you can't see damage — moisture is hiding behind the wall
- Soft or spongy drywall when you press on it — the gypsum core is saturated
- Paint bubbling or peeling in spots that weren't recently painted — moisture is pushing out from behind
- Visible mould spots on walls or ceilings — especially in corners and where walls meet ceilings
Any of these warrant a professional assessment. The sooner you deal with it, the less it costs.
Get Your Water Damage Fixed Right
Here's the bottom line: water damage doesn't get better on its own. That ceiling stain isn't going to magically disappear, and the longer you wait, the more it costs to fix. Mould grows, drywall deteriorates, and a $500 repair turns into a $2,000 problem.

Frequently Asked Questions
Water damage repair in Toronto ranges from $450 to $3,000+ depending on the severity. A small ceiling stain under 2x2 feet runs $450-$800. A medium repair like a 4x4 wall section with bubbling and damaged drywall costs $800-$1,800. Large-scale damage involving mould remediation, multiple sheets of drywall, and insulation replacement runs $1,800-$3,000+. These prices include drywall removal, replacement, stain-blocking primer, and painting to match. We always provide a firm quote after assessing the damage in person.
No, and I see this mistake constantly. Painting over a water stain with regular paint is a waste of money — the stain bleeds through within weeks. Even if you use a stain-blocking primer, you're only masking the symptom. The real question is: has the source of the leak been fixed? If yes, we can properly repair and seal the area. If no, the stain will come right back. We always check moisture levels with a meter before we start any repair. If the area is still wet, we'll tell you to call a plumber first.
Start with a plumber or roofer to fix the source of the leak. Once the leak is confirmed fixed and the area is dry, call us for the cosmetic and structural repair — removing damaged drywall, replacing insulation if needed, patching, priming with stain-blocker, and painting. If you're not sure where the water is coming from, we can assess the damage and point you in the right direction. We won't start repairs until the source is addressed because that's just throwing your money away.
It depends on severity. A small ceiling stain repair takes 2-3 days — one day for removal and patching, drying time, then priming and painting. Medium repairs run 3-5 days. Large-scale damage with mould or multiple areas can take 5-7 days or more. The biggest variable is drying time. We never rush it. If we seal up damp drywall, you'll have mould growing behind your walls within months. Patience during the repair prevents a much bigger problem later.
It depends on the cause. Sudden and accidental damage — like a burst pipe — is usually covered. Gradual damage from a slow leak you ignored for months? Typically not. We can provide detailed invoices and photo documentation that insurance companies need for claims processing. We've worked with plenty of Toronto homeowners going through insurance claims, and we know how to document the work properly. But we're painters, not adjusters — always check with your insurance company first.
We use shellac-based primers like Zinsser BIN for water stain repair. It's the only primer I trust to permanently block water stains, tannin bleed, and smoke damage. Latex-based stain blockers don't cut it for serious water stains — I've seen them fail too many times. Shellac seals the stain completely, dries in under an hour, and gives you a rock-solid base for your topcoats. It stinks during application, but it's the gold standard and the results speak for themselves.
Absolutely — condo water damage is a huge part of our work. Upstairs neighbour's dishwasher leak, bathroom overflow from the unit above, HVAC condensation drips — we've seen it all in Toronto condos. We carry proper insurance, we're familiar with condo building access rules, and we book freight elevators when needed. If your condo management needs documentation for the responsible party, we provide detailed reports. Check out our condo painting services for more on what's involved.
Yes. This is one of the hardest parts of water damage repair and where most contractors fall short. Toronto homes have everything from smooth ceilings to heavy knockdown texture to old stipple. We match the texture before priming and painting so the repair blends in completely. If your ceiling has an older texture pattern, we may recommend retexturing the entire ceiling for a uniform look — we'll give you both options and pricing upfront.
