Gutter guard replacement in North York: clogged guards, sagging trough
Quick answer: In October 2026 DT Cleaning replaced clogged gutter guards on a North York house with aluminum mesh guards at $7 to $8 per linear foot. The whole eavestrough had sagged under the dirt, and levelling the 2 sagging sections was included.
Why the eavestrough sagged under the old guards
Quick answer: Over the winter the built-up dirt froze, and the whole system sagged with it, so the eavestrough did not work properly at all. The sag was in 2 places, and the photos show moss growing through the old mesh.
Old guards off, 2 sagging sections levelled
Quick answer: The crew removed the old guards, cleaned the whole system and flushed it with water, which showed where water sat. They took down part of the eavestrough and levelled it in the 2 places where it had sagged; the levelling was included in the installation price.
The City of Toronto advises: "Fix any leaks and repair any low spots or sagging areas along your eavestroughs."
A 40-foot ladder and 2 workers for gutter guard work in North York
Quick answer: The job needed a 40-foot ladder at its full height, and someone had to hold it because it is not very safe. Levelling an eavestrough that high takes 2 people, so Vitalii from our crew worked with a partner.
"We had to use a 40-foot ladder. That is hard, because the 40-foot ladder is at its maximum height, and someone has to hold it, because it is not very safe. Levelling an eavestrough at that height is hard too. For this kind of work you need two people."

Ontario's IHSA Ladder Safety guide says: "Secure the ladder by tying it off, or have another person hold the bottom of the ladder."
Fitting new aluminum guards under drooping shingles
Quick answer: Shingles drooped into the eavestrough, so the crew had to fit each new guard properly while taking care not to damage the shingles. In October 2026 the guards went on over the whole system, and the client was quite satisfied.
9 leaking spots to seal once the eavestrough is dry
Quick answer: The crew found 9 more spots where water leaked, told the client first and booked the next visit to seal them with silicone: the whole system was wet, and silicone does not set on a damp surface. Repairs at DT Cleaning start at $130.
"During the inspection we found 9 more spots where water was leaking. We told the client first and said we would come back at the next appointment to seal them with silicone, because the whole system is wet, and there is no point putting silicone on a damp surface: it simply will not set."
Vitalii, DT Cleaning crew, North York, October 2026 (translated from the crew's voice note)
The Government of Canada gives the same fix: "Seal small cracks in eavestroughs, downspouts, and downspout extensions with silicone sealant".
