What's the cost to repair a 200 sq ft section of water-damaged hardwood in my Vancouver living room?

Repairing a 200 sq ft section of water-damaged hardwood in a Vancouver living room costs between $2,000 and $6,500 depending on the extent of damage, whether the subfloor is affected, and whether refinishing the entire room is needed to blend the repair. Water damage is one of the most common hardwood flooring issues in Metro Vancouver due to our marine climate, and the cost depends heavily on how deep the damage goes.

The first step is assessing the severity. Surface-level water damage where boards have cupped or show staining but the subfloor beneath is sound is the least expensive to address. If boards have buckled, warped severely, or show mould growth on the underside, the damage has penetrated deeper and repair costs increase. If the plywood subfloor itself is swollen, delaminated, or showing mould, that adds a significant layer of work and cost. A professional installer will pull a few boards to inspect the subfloor condition before providing a final quote.

For a board replacement repair on 200 sq ft, the cost breakdown looks like this. Removing the damaged boards runs $2 to $4 per sq ft, or $400 to $800 for the affected area. This is careful work because the installer must remove damaged boards without damaging adjacent sound boards, which means cutting out tongue-and-groove connections precisely. Matching replacement hardwood is often the trickiest part of the project. If your floor is a common species like red oak or maple in a standard width, finding matching stock is straightforward at $5 to $12 per sq ft for materials. If your floor is an uncommon species, a discontinued product, or has developed a patina from years of aging, matching becomes much harder and potentially more expensive. Expect to pay $600 to $2,400 for 200 sq ft of replacement boards plus the 10% overage needed for cutting waste.

Installation of replacement boards costs $4 to $8 per sq ft, or $800 to $1,600 for this area. The installer must weave new boards into the existing floor, which requires face-nailing in some spots and careful fitting to maintain the tongue-and-groove integrity. Subfloor repair, if needed, adds $500 to $2,000 depending on the extent. Replacing a section of water-damaged plywood subfloor involves cutting out the compromised section, sistering new plywood to the floor joists, and ensuring the surface is level before new hardwood goes down.

Here is the cost factor many homeowners do not anticipate: refinishing. New hardwood boards will not match the colour, sheen, or wear pattern of your existing floor. To achieve a seamless repair, the entire living room typically needs to be sanded and refinished as one continuous surface. Full-room refinishing at $3 to $6 per sq ft can add $1,500 to $4,500 if your living room is 500 to 750 sq ft total. Some homeowners opt to refinish only the repaired area and accept a slight colour difference, but in a main living space this is usually noticeable and worth avoiding.

Addressing the source of water damage is critical before any repair begins. In Vancouver, common culprits include slow plumbing leaks beneath the floor, failed dishwasher or washing machine connections, condensation from poorly insulated windows during winter, and water tracking in from exterior doors during heavy rain. If the moisture source is not identified and resolved, the new boards will suffer the same fate. A moisture meter reading of the subfloor and surrounding areas should be part of any repair assessment.

For a straightforward board replacement with sound subfloor and full-room refinishing, budget approximately $3,500 to $5,500 as a realistic middle estimate in Metro Vancouver. If subfloor repair is needed, push that to $5,000 to $6,500. Get matched with an experienced hardwood repair specialist through Vancouver Floor Installers for a proper assessment and free estimate.
