Water Damage Drywall Repair in Toronto for Leaks & Floods

Ceiling Leaks, Burst Pipes & Flooded Basements in Toronto

Toronto Drywall Pro has handled water damage drywall repair in Toronto homes and condos since 2002, with more than 2,000 drywall projects completed across the GTA. Water damage rarely waits. A burst supply line in January, a slow ceiling leak from the unit upstairs, ice damming on a detached house or semi, or a flashing failure during spring thaw can saturate drywall in hours. The longer it sits wet, the larger the eventual repair gets, and the higher the mould risk inside the wall cavity.

We assess within 24 to 48 hours across the GTA, document the damage for your insurance claim, and remove any compromised panels before mould can establish. After dry-out is verified, the same in-house crew handles the drywall installation, taping, mudding, and finishing, so the repaired area matches the surrounding wall under paint.

How Much Does Water Damage Drywall Repair Cost in Toronto?

These are 2026 price ranges for water-damaged drywall in Toronto and the GTA:

• Small water damage area (single ceiling spot or wall section): $400 to $800 per affected area
• Medium water damage (multiple panels, partial dry-out): $800 to $1,600 per affected area
• Large water damage (full room, extensive saturation): $1,600 to $2,500 plus
• Condo upstairs leak ceiling repair: $600 to $1,400 typical
• Per-square-foot rate for water-damaged drywall replacement: $4 to $9
• Moisture-resistant Green Board upgrade premium: 20 to 30 percent above standard
• Mould remediation coordination (if required): Quoted separately by licensed partner

Taping, mudding, and stain-blocking primer on the replaced sections are included in these ranges. Most insurance-covered claims invoice the homeowner per claim documentation. We provide line-item pricing and itemized scope-of-work for the adjuster.

Why the First 48 Hours Decide the Size of the Repair

The single biggest factor in whether water damage becomes a small repair or a large one is how quickly the wet drywall comes out. Within 24 to 48 hours of saturation, the cavity is still dry-out-able and the wall surface can often be saved. Past 72 hours, mould colonization starts on the back side of paper-faced drywall, and the affected sections need to be removed entirely.

That’s why we assess within 24 to 48 hours of your call across the entire GTA, and same-day when the schedule allows.

What Does Your Insurance Adjuster Need to Approve the Claim?

When you file a claim, your insurer wants three things documented:

1. Source of the loss. Where the water came from, ideally with a photo of the failed pipe, appliance, or flashing.
2. Extent of the damage. Moisture-meter readings showing what’s wet and what’s not, photos of staining, sagging, and any visible mould.
3. Scope of repair. Written list of what needs to come out and what needs to be replaced, with line-item pricing.

Toronto Drywall Pro produces all three on the assessment visit. Most adjusters will approve the scope and authorize work to begin within a day or two of receiving our documentation.

Condo Ceiling Repair After an Upstairs Leak

Condo upstairs leaks are one of our most common Toronto jobs. The pattern is familiar: dishwasher overflows two floors up, supply line fails on a fridge, toilet supply hose ruptures while the owner is on vacation. Water travels down the drywall ceiling and walls in the units below, often to two or three floors of damage before anyone notices. The same thing happens in stacked townhouses and older low-rise rental buildings, where a single bathroom leak can stain the ceiling of the unit below.

For condo work we coordinate with property management on:

• Elevator booking for material delivery and waste removal
• Parking access for our trucks and dumpster placement if needed
• Water shut-off windows if cavity work requires it
• Dust-containment requirements per building rules
• After-hours scheduling if the building requires it for noisy work

We’ve worked through this protocol in downtown Toronto towers, Etobicoke Humber Bay condos, North York Yonge-corridor buildings, and Mississauga Hurontario-corridor high-rises. For ceiling cracks, sagging, or holes that aren’t caused by a leak, see our ceiling drywall repair service.

What Is Water Damage Drywall Repair?

Water damage drywall repair is the process of removing and replacing gypsum panels and framing that have been saturated by a leak, flood, or condensation event. Unlike standard drywall repair, water damage work must address the moisture source before any patching begins, because new drywall installed over wet framing will develop mould within days. The repair sequence is: identify and stop the leak, dry the structure, inspect framing for rot or mould, replace affected panels with moisture-resistant material where applicable, then tape, mud, and finish to match the existing surface. Toronto homes experience water damage from roof leaks, basement seepage, plumbing failures, and ice damming on flat roofs, all of which require slightly different repair approaches.

What Does Water Damage Drywall Repair Include?

• Moisture assessment and leak source identification before any demo begins
• Demo of saturated panels and exposure of framing for drying and inspection
• Framing assessment for mould, rot, and structural integrity
• Moisture-resistant Green Board or Purple Board installation on all below-grade and wet-area replacements
• Standard drywall replacement on above-grade sections matched to existing panel thickness
• Three-coat taping and mudding with joint compound, plus texture matching to the surrounding undamaged surface
• Stain-blocking primer so the area is ready for interior painting

What Does a Water-Damaged Ceiling or Basement Wall Cost to Fix?

Water damage drywall repair in Toronto runs $400 to $2,500 for typical residential repairs depending on the area affected and whether framing replacement is required. A single ceiling section from a roof or plumbing leak (10 to 40 sq ft) runs $400 to $1,200. A basement wall section from seepage or flooding runs $600 to $2,000. Extensive multi-room water damage is quoted on a full walk-through. Free on-site assessment with moisture reading included.

Who Needs Water Damage Drywall Repair?

Homeowners dealing with ceiling damage after a condo upstairs leak. Insurance claimants who need a contractor that can provide moisture readings and line-item documentation. Basement homeowners after a spring flood or burst pipe. Anyone whose drywall has visible staining, soft spots, or mould growth from prolonged moisture exposure.
