Eavestrough & Gutters in Ontario
Eavestroughs (most Ontarians say "eavestrough," not "gutter," though the terms mean the same thing) are the trough system running along your roofline that catches runoff and carries it away from your foundation, siding, and landscaping. Get this wrong and water ends up in your basement, behind your fascia boards, or eroding the soil around your footings. It's a small system with an outsized job, and Ontario's freeze-thaw winters and heavy spring rain put real stress on it every year.
This category covers new eavestrough installation, replacement of old or damaged runs, gutter guard and leaf-screen systems, repairs (sagging sections, leaking joints, pulled-away hangers), and eavestrough cleaning and maintenance. Some contractors handle the full envelope (fascia, soffit, downspouts) while others specialize narrowly in seamless aluminum eavestrough.
What to look for in a contractor
- Seamless aluminum capability: most quality installs today use a portable roll-forming machine on site to produce one continuous run per side of the house, cutting down on leak points compared to sectional gutters.
- Correct sizing and slope: 5-inch is standard on most homes, but larger roof areas or steep pitches often need 6-inch trough and oversized downspouts to keep up with volume.
- Hanger spacing and fastening: hidden hangers spaced properly (not just spikes and ferrules, which loosen over time) hold up far better through Ontario's winters.
- Manufacturer warranty and workmanship warranty: both should be in writing, separately.
- WSIB coverage and liability insurance: this is ladder work on every job, so ask before anyone gets on your roof.

Common questions about eavestrough & gutters
- How much does new eavestrough installation cost in Ontario?
- For a typical single-family home, seamless aluminum eavestrough usually runs a few thousand dollars installed, depending on the linear footage, the number of corners and downspouts, the trough size (5-inch vs 6-inch), and whether old gutters need to be torn off first. Larger homes, steep rooflines, or upgrades like gutter guards push the price higher. Get quotes from at least two or three contractors on this list since pricing varies a fair amount across the province.
- How often should eavestroughs be cleaned or inspected?
- Most homes need a cleaning at least twice a year, once in late spring after seeds and buds drop and again in late fall after leaves come down. Properties with a lot of overhanging trees may need it more often. It's also worth a quick visual check after any major windstorm, since that's when hangers and sections tend to pull loose.
- What should I expect during an eavestrough replacement?
- A full replacement typically starts with tearing off the old system, checking the fascia board underneath for rot (which needs to be fixed first or the new hangers won't hold), then forming and installing new seamless troughs on site with a roll-forming machine, followed by downspouts and splash blocks or extensions to direct water away from the foundation. A straightforward job on an average house can often be done in a day.
- How can I tell if an eavestrough job was done well?
- Look for consistent slope toward the downspouts with no visible sagging or standing water after a rain, tight seams at corners and end caps, hangers spaced evenly rather than widely gapped, and downspouts that discharge well away from the foundation rather than dumping right against it. If water overflows the front of the trough during heavy rain, it's usually undersized, poorly sloped, or clogged.
