Why eavestrough cleaning matters more than it looks
Rainwater off a typical Toronto semi runs to a few hundred litres in a single storm, and every drop of it is supposed to leave through the trough and the downspout. Block that path and the water finds another one. It runs behind the fascia and rots the board. It sheets down the brick and stains it. Worst of all it dumps at the base of the wall, saturates the backfill and puts pressure on a basement that was never meant to take it.
Nesting birds, maple keys, shingle grit and the shredded leaves that fall late all end up as a dense mat in the low end of the trough. That mat holds water, and standing water is heavy enough to pull hangers out of the fascia over a season or two.
How I clear a trough properly
Scooping by hand beats every shortcut. A leaf blower on a roof edge throws the debris into the neighbour's yard and packs the wet sludge harder into the outlet. My method is slow and boring, which is the point.
- Set and foot the ladder on level ground with a stabiliser off the trough
- Hand scoop debris into a bucket, never over the side
- Flush the full run with a hose to prove the fall
- Clear each downspout from the top and check flow at the bottom
- Snake or split a stubborn elbow rather than force it
- Wipe the trough face and rinse anything that landed on the siding
- Bag the debris and take it away
The flush is the part people skip and the part that proves the job. A trough can look spotless and still hold water because it has lost its fall or because the outlet is choked at the elbow behind the downspout. Water tells you the truth in about thirty seconds.
Small repairs while the ladder is up
Cleaning and fixing go together, so I carry spikes, hidden hangers, screws and sealant on every eavestrough cleaning visit. A hanger that has worked loose gets refastened into solid fascia, not back into the same chewed hole. A section that sags and ponds gets lifted and re-hung to a proper fall, roughly six millimetres over every three metres (about a quarter inch in ten feet). Open end caps and dried-out seams get cleaned back and re-sealed with a gutter sealant that stays flexible in the cold.
Loose downspouts are the other common find. Straps pull off brick, elbows separate, and the bottom section ends up dumping right at the wall. Refastening those and adding a proper extension is quick work once the ladder is already set.
Guards, extensions and ice dams
Gutter guards help, within limits. A decent mesh or micro-mesh guard keeps leaves and maple keys out and turns a twice-yearly clean into a yearly check. No guard stops shingle grit and fine pollen from building a sludge layer, and the cheap plastic hedgehog inserts tend to trap debris rather than shed it. I will fit guards where the roof and trough profile suit them and say so when they do not.
Downspout extensions do more for a dry basement than almost anything else on the outside of a house. Water needs to land at least a metre and a half from the wall, on ground that slopes away. Ice dams are a roof and attic problem at heart, driven by heat escaping into the attic, but a trough packed with frozen debris makes it much worse, which is why the late autumn clean matters across the GTA.
Where I draw the line on height
Ladder work has a sensible ceiling, and I stay under it. Single-storey homes are straightforward. Two-storey homes are fine where I can set a ladder on firm, level ground with clear access and a stabiliser. Steep lots, third storeys, walkouts with a long drop to the trough and anything needing a lift or roof anchors are not my work, and I will tell you that before you book rather than after I arrive. Nothing about eavestrough cleaning is worth an ambulance.
