Eavestrough Re-Sloping Cost in Ottawa

Fixing Eavestrough Slope Problems in Ottawa

Re-sloping improperly graded eavestroughs on an Ottawa home typically costs $200 to $600 for a straightforward adjustment on a single-storey bungalow, and $400 to $1,000 or more on a two-storey home where access is more difficult. If the slope problem has caused standing water and corrosion damage to the gutter trough itself, you may also need section replacement, which pushes the total to $600 to $1,500 depending on how much material needs replacing.

Improper slope is actually the single most common eavestrough defect in Ottawa, and it matters more here than in milder climates. When eavestroughs do not slope at least one-quarter inch per 10 feet of run toward the nearest downspout, water pools in the trough. In summer, that standing water breeds mosquitoes and accelerates corrosion at seams. In winter, it freezes into a solid block of ice that can weigh enough to pull hangers out of your fascia. Given that Ottawa sees 50-plus freeze-thaw cycles per winter, even a minor pooling issue compounds into serious structural damage quickly.

The repair process itself involves loosening or removing the existing hangers, re-establishing the correct slope using a level line from the high point to the downspout outlet, and then resecuring the hangers at the corrected height. If your original installation used spike-and-ferrule hangers — common on older homes in neighbourhoods like Westboro, Alta Vista, and Manor Park — most contractors will recommend upgrading to hidden screw-in hangers at the same time, which adds roughly $3 to $5 per hanger but dramatically improves holding strength against Ottawa's snow loads.

Sometimes the slope problem is actually caused by fascia board deterioration rather than incorrect installation. Ottawa's freeze-thaw cycles and ice damming can rot fascia wood over time, causing the gutter to sag at weak points. If your contractor discovers rotted fascia during the re-slope, expect to add $12 to $25 per linear foot for fascia replacement in those sections. Aluminum fascia capping over new wood adds another $8 to $15 per linear foot but prevents future rot.

Before hiring someone, grab a garden hose and run water through your eavestroughs on a dry day. Watch where water pools or barely moves — this tells you and your contractor exactly which sections need attention, potentially saving you money by targeting only the problem areas rather than re-sloping the entire system.

For a project like this, getting at least three quotes is worth the effort. Each contractor may diagnose the root cause differently — some may recommend a full re-slope while others identify that only one or two sections need adjustment.
