Fall in Toronto and the GTA brings heavy rain, cold nights, and the first freeze-thaw cycles of the season. Unfortunately, it’s also when basement leaks and foundation issues become most noticeable. If you’re planning to enjoy a dry, stress-free winter, now is the time to check if your home needs professional waterproofing.

Here are the top signs your basement needs waterproofing before winter hits — and how SealCo can help.

1. Damp Walls or Floors

If your basement walls feel cold and damp, or if you notice moisture on the floor after rain, it’s an early warning sign of water intrusion. Left untreated, this moisture can turn into major seepage when the ground freezes.

2. Musty Smells or Mold

That “basement smell” is usually caused by hidden moisture and mold growth. Mold spreads quickly in damp conditions and can damage walls, flooring, and even your family’s health.

3. Water Stains or Discoloration

Brown or yellow stains on walls, floors, or near baseboards indicate water has been seeping in over time. These stains mean your foundation is already struggling against water pressure.

4. Cracks in Foundation Walls or Floors

Even small cracks allow water to seep through — and with freeze-thaw cycles, cracks will expand, letting in more water. If you notice cracks, don’t wait until spring to repair them.

5. Pooling Water After Rain

If water collects near your foundation after storms, it’s a sign your grading, gutters, or drainage system isn’t working properly. This water eventually finds its way into your basement.

Why Fall is the Best Time to Waterproof

• Winter makes leaks worse as water freezes and expands.
• Contractors’ schedules fill up fast after the first big storm.
• Waterproofing now means peace of mind all winter long.
