Residential Water Damage Restoration

When water gets into your home, it never stays where it started, it runs under flooring, wicks up drywall, and hides in the spaces you can't see. Firstline stops the damage, dries your home completely, and puts it back together so it feels like home again.

For 20 years, families across Toronto and the GTA have trusted Firstline to handle the worst day in their home. We are fully licensed and insured, WSIB covered, and 5-star rated on Google. We don't just dry the water and leave, we rebuild, so the last step of your claim is a finished home, not a torn-up one.

The water on your basement floor is the easy part. The threat to your family's home is the moisture that disappears into the building, and keeps doing damage long after the surface looks dry.

• Hidden moisture: Water trapped behind drywall and under flooring stays wet for weeks, quietly rotting framing and feeding mould you can smell but can't see.
• Mould in 24-48 hours: Health Canada and CMHC link indoor mould to respiratory problems, and in a home with kids, older parents, or anyone with allergies or asthma, that is not a risk to gamble with.
• Contaminated water: A backed-up drain or sewage flood carries bacteria into your living space, which is a health hazard a wet-vac and bleach will never make safe.

You cannot meter your own walls or see inside your subfloor. We can, and we don't call a job done until the numbers prove your home is dry. Call us before a small leak becomes a gut renovation.

A house is mostly drywall, wood, insulation, and porous flooring, all of which soak up water and hold it. Engineered and hardwood floors cup and buckle, baseboards swell, drywall crumbles, and the insulation inside your walls turns into a wet sponge that never dries on its own and becomes a mould factory behind the surface.

That is why drying a home is a controlled process, not a guess. We map exactly how far the water travelled, set the right equipment for your home's layout and materials, and monitor moisture levels daily until everything reads dry. The goal is simple: save what can be saved, replace only what must be, and make sure the damage doesn't quietly continue inside your walls after we leave.

It is tempting to grab a wet-vac, point a couple of fans at the floor, and hope it dries out. The trouble is that household tools only touch the surface. They cannot pull moisture out of the wall cavity, dry the subfloor, or tell you whether the water reached materials you can't see, and that hidden moisture is exactly what becomes mould and rot weeks later.

The cheap option is just as risky. A handyman who skips moisture readings, leaves wet insulation in the walls, or paints over a problem isn't saving you money, he's setting up a second, bigger loss and a claim your insurer may deny because the damage wasn't documented or dried properly. Doing it right the first time, with the right equipment and proof of drying, is what actually protects your home and your wallet.
