Burst Pipe Damage Restoration Unionville

When a pipe bursts, you don't have a plumbing problem, you have a water problem that's already inside your building. Firstline is one accountable team that stops the spread, dries the structure properly, and rebuilds it back to pre-loss condition or better, so you're not juggling four contractors while the damage gets worse.

We've handled burst pipes across Unionville and the GTA for 20 years. We're fully licensed and insured, WSIB covered, 5-star rated on Google, and available 24/7/365 with a 45-minute emergency response. From the first emergency call to the final coat of paint, you deal with one crew that owns the outcome.

The puddle on your floor is the part that's easy to deal with. The dangerous water is the water that travelled, down inside wall cavities, across the top of ceilings, under flooring, and into insulation. A burst supply line can release many litres per minute, and most of that volume goes where gravity takes it, not where you can reach it with a towel.

• Water wicks upward into drywall and outward along the bottom plate of your walls, spreading well past the visible wet patch.
• Saturated insulation holds water like a sponge and stops drying on its own, it stays wet and feeds rot and mould for weeks.
• Trapped moisture under flooring and behind baseboards is invisible from the room, so it's almost always missed by anyone without moisture meters and thermal imaging.

This is why a burst pipe that looked fine after we dried the floor turns into a mould and structural problem a month later. If the hidden water isn't found and removed, it doesn't go away, it just goes quiet.

A burst pipe usually starts as clean water, which feels reassuring. It shouldn't. According to Health Canada and CMHC, standing moisture inside building materials can begin feeding mould growth within 24 to 48 hours. Clean water that sits in drywall and insulation degrades quickly, and the warm, dark, undisturbed space inside your walls is exactly where mould wants to grow.

That's the whole reason speed matters so much. The goal isn't just to remove the water you can see, it's to get the hidden moisture out of the structure before that 24-to-48-hour window closes and a water loss quietly turns into a mould remediation job. Drying properly the first time is far cheaper and far less disruptive than tearing it all open later.

It's tempting to towel it up, run a household fan for a couple of days, and call it done. The problem is that a box fan can't dry a saturated wall cavity, and a wet/dry vac can't reach the water sitting under your subfloor. Without moisture mapping, you have no way of knowing whether the structure is actually dry, you just know the surface feels dry, which is not the same thing.

The cheap fix also leaves you exposed on the insurance side. A handyman who doesn't document the loss properly gives your carrier no reason to pay for hidden damage they can't see in a photo. When the mould shows up two months later, you're now paying out of pocket for a second, bigger job that the first one should have prevented. Doing it right once is the actual budget option.
