Water damage gets worse fast. Whether it’s a burst pipe, a basement flood, or a slow leak you just discovered, the first few hours matter for limiting damage and preventing mould. This guide covers what to do first in a Toronto or GTA home, and when to bring in a professional.

1. Stay Safe First
If water is near electrical outlets, panels or appliances, avoid the area and shut off power to that part of the home only if you can do so safely. Never stand in water near live electrical. If you smell gas or suspect a sewage backup, leave and call the appropriate utility or professional.
2. Stop the Water Source
Shut off the main water supply if the leak is from plumbing. For appliance leaks, close the local shut-off valve. Stopping the source is the fastest way to limit how far the damage spreads.
3. Document Everything for Insurance
Before you start cleaning, take photos and video of all affected areas and belongings. Keep records and contact your insurance provider early — documentation makes claims smoother.
4. Remove Water and Start Drying
Move valuables and furniture out of the wet area, remove standing water where safe, and start air circulation with fans and a dehumidifier. The longer materials stay wet, the higher the risk of mould and structural damage.
5. Watch for Hidden Damage
Water travels behind walls, under flooring and into subfloors and insulation. Surfaces can look dry while moisture remains trapped — a common cause of mould weeks later. Professional drying equipment and moisture readings help confirm an area is truly dry.

Water Damage FAQ
How quickly does water damage cause mould?
Mould can begin to develop within 24–48 hours of materials staying wet, which is why fast drying matters.
Does insurance cover water damage?
It depends on the cause and your policy. Sudden, accidental damage is often covered, while gradual leaks may not be. Document everything and contact your insurer early.
Can you repair the damage after drying?
Yes. Oakbuild Construction handles the reconstruction after water damage — drywall, flooring, trim and finishing — so your home is restored, not just dried out.
