Water damage floor repair

Squeaky Floor repairs flooring and subfloor damaged by a leak or flood, starting with what the water actually reached rather than only what you can see.

The visible damage is usually smaller than the wet area. That is the part that matters.

Why water damage is bigger than it looks

Water spreads laterally. A leak under a dishwasher or a burst supply line does not stay where it landed; it runs along the top of the subfloor, wicks into the end grain of flooring boards, and travels under cabinets and along joist bays where nothing is visible. By the time flooring cups, buckles or stains, the wet area is almost always larger than the marked area. That is why the first thing we do is establish the actual extent of what got wet rather than starting from the stain. Different materials fail differently, too. Solid hardwood cups as its underside takes on more moisture than its top. Engineered hardwood and laminate delaminate, with the layers separating irreversibly once the core is saturated. Vinyl may look untouched while trapping moisture against the subfloor beneath it. And the subfloor itself, particularly oriented strand board, swells at the edges and does not recover its thickness when it dries. Repairing the surface over a compromised subfloor is a repair that fails.

What water actually does to a floor

Each material fails in its own way, which is why the assessment matters more than the estimate.

Solid hardwood cupping

The underside absorbs more moisture than the top, so board edges rise. Often recoverable if dried properly and not sanded too soon.

Engineered and laminate delamination

The layers separate once the core is saturated. This is not reversible and the affected planks need replacing.

Subfloor panel swelling

Oriented strand board in particular swells at the panel edges and does not return to its original thickness on drying.

Hidden lateral spread

Water travelling under cabinets and along joist bays, well beyond the area that shows a stain.

Trapped moisture under vinyl

A resilient floor can look undamaged while holding moisture against the subfloor underneath it.

How we approach water-damaged flooring

Confirm the source is stopped

There is no point repairing a floor that is still getting wet, so we establish that the leak is dealt with first.

Map the actual wet area

The extent of the damage is established before scoping, because it is nearly always larger than the visible mark.

Repair from the subfloor up

Any compromised subfloor is dealt with before new flooring goes over it, rather than covering the problem.

What water damage floor repair typically costs

A starting range based on published Ontario and Toronto-area cost data for this kind of work, not our confirmed rate card. This is the widest range of anything we do, because scope varies enormously with how far the water travelled.

Our Process

From your call to a sound floor

1

Tell us what happened and when

The source and the timeline matter, because how long a floor stayed wet shapes what is salvageable.

2

We map the wet area

Establishing the real extent before quoting, rather than pricing from the visible stain.

3

Written quote with a salvage read

We will tell you honestly what we expect to save and what we do not.

4

Repaired from the subfloor up

Subfloor addressed first, then flooring, so the repair holds.

What homeowners tell us

Real feedback from customers we have worked with.

5/5

They repaired deep scratches and chipped areas in our hardwood flooring. The available repair options were explained clearly and the results were excellent. The floor looks refreshed, and the damaged spots are no longer noticeable.

5/5

They repaired several damaged hardwood boards in our living room and blended the replacements beautifully with the existing floor. The team was punctual, tidy, and careful throughout the job. You can barely tell where the damage was.

Michael

5/5

Our laminate flooring had lifted near the kitchen after a small water leak. They replaced the affected sections and repaired the surrounding area. The finished repair looks clean and matches the rest of the flooring very well.

Water damage floor repair questions

Can a water-damaged hardwood floor be saved?

Sometimes, and it depends mostly on how long it stayed wet and what the subfloor did. Solid hardwood that has cupped will often flatten substantially on its own once the moisture source is gone and the floor has dried properly, which is why sanding it flat immediately is a mistake. Engineered and laminate flooring that has delaminated is not recoverable and those planks need replacing.

How do you know how far the water spread?

By checking rather than assuming. Water runs along the top of the subfloor and wicks into end grain, so it travels under cabinets, along joist bays and beneath adjoining rooms without leaving a mark. We establish the actual extent before scoping the work, because a quote based on the visible stain is a quote that will change.

Do you deal with the insurance side?

We provide a written scope and quote setting out what we found and what the repair involves, which is the documentation most people need for a claim. We are not insurance adjusters and we do not negotiate on your behalf, but a clear written assessment of the damage is usually the most useful thing a contractor can give you.

Our vinyl floor looks fine after a leak. Should we still check?

Yes, and this is a genuinely common trap. Resilient flooring like sheet vinyl or glued LVP can look completely undamaged while holding moisture against the subfloor beneath it, where it has nowhere to evaporate. That is how a floor that appears fine develops a soft spot or an odour months later. It is worth checking rather than assuming.

Does swollen subfloor have to be replaced?

Usually, where oriented strand board is involved. OSB swells at the panel edges when it gets wet and does not return to its original thickness as it dries, so the swelling is permanent and leaves a ridge that will telegraph through any new flooring laid over it. Plywood tolerates a wetting rather better. We assess what you actually have rather than assuming the worst.
