As the colorful leaves of High Park start to fall and temperatures begin to drop, homeowners in Toronto know that winter is right around the corner. While it’s easy to focus on raking leaves or checking the furnace, there’s one critical task that should never be overlooked — gutter cleaning. Neglecting your gutters before winter can lead to costly damage, ice buildup, and even roof leaks.
At Castor Tree Care Services, we understand how the changing seasons in Toronto affect your property. Here are the top signs your gutters need professional cleaning before winter arrives.
1. Overflowing Water During Rain
If you notice water spilling over the edges of your gutters during rainfall, it’s a clear sign they’re clogged with leaves, twigs, and debris. In the High Park area, where mature trees shed heavily in the fall, this is a common problem. Overflowing water can damage your home’s siding, foundation, and landscaping — all of which are far more expensive to repair than a seasonal gutter cleaning.
2. Sagging or Pulling Gutters
When gutters get too heavy with trapped debris or standing water, they begin to sag or pull away from the roofline. This not only looks unsightly but also prevents proper drainage. A professional cleaning can remove the buildup and help ensure your gutters are securely reattached before the first snow arrives.
3. Visible Plant Growth

If you can see small plants or moss growing in your gutters, it’s a sure sign that dirt and moisture have accumulated over time. Once temperatures drop below freezing, that trapped moisture can turn into ice, causing cracks or splits in the gutter system. Having your gutters cleaned before winter prevents these issues and helps water flow freely when snow begins to melt.
4. Water Stains or Damage on Exterior Walls
Notice dark streaks or water stains on your siding or brickwork? This often means water is escaping from clogged gutters or overflowing near the roofline. If left unchecked, this moisture can seep into your walls and cause insulation or structural damage — especially during freeze-thaw cycles common in Toronto winters.
5. Ice Dams Forming in Winter
If you’ve experienced ice dams in past winters, clogged gutters may be to blame. When leaves and debris block the flow of melted snow, water backs up under your shingles and freezes, creating ice dams that can cause roof leaks and interior damage. Prevent this by scheduling a professional gutter cleaning in High Park before the first frost.

6. Pests or Birds Nesting in Gutters
Another sign that your gutters need attention is the presence of birds, squirrels, or insects nesting inside. These pests are attracted to built-up debris and standing water. A seasonal cleaning removes their nesting materials and discourages them from returning.
