Spring Eavestrough Maintenance After Ottawa Winters

Spring eavestrough maintenance is one of the most important things you can do to protect your Ottawa home, because winter puts more stress on gutter systems here than almost anywhere else in Canada. After enduring over 200 centimetres of snowfall, dozens of freeze-thaw cycles, and potential ice dam loading, your eavestroughs need a thorough inspection and cleaning before Ottawa's heavy spring rains arrive in May. Start this work as soon as temperatures consistently stay above 5 degrees Celsius and the ground is firm enough for safe ladder placement — typically late April in Ottawa.

Begin with a visual inspection from ground level before you touch a ladder. Walk the perimeter of your home and look for sections of eavestrough that are sagging, pulling away from the fascia, or visibly tilted. Check for dents, cracks, or sections where ice has pushed the gutter out of alignment. Note any spots where water staining on the fascia or soffit suggests leaks or overflow during winter. Ground-level inspection takes five minutes and tells you where to focus your attention.

The Hands-On Checklist

Once you are safely on a ladder — always on dry, firm ground with a stabilizer bar — start by removing all debris from the eavestrough troughs. Winter compresses leaves, shingle grit, and organic matter into a dense layer that blocks water flow. Use a gutter scoop or garden trowel rather than your hands, as sharp metal edges and hidden debris can cause cuts. Work away from the downspouts first, pushing debris toward the outlets where you can bag and remove it.

After clearing the troughs, flush the entire system with a garden hose starting at the end farthest from each downspout. Watch the water flow — it should move steadily toward the downspout without pooling anywhere. Standing water indicates a slope problem that needs correction. Pooling water in eavestroughs freezes first the following winter and starts the ice dam cycle all over again. Proper slope is one-quarter inch per 10 feet of run, and a contractor can re-slope sagging sections for $150 to $400 depending on the length.

Check every downspout for blockages by running water through from the top. If water backs up, the downspout is clogged — usually at the upper elbow where it connects to the eavestrough. A plumber's snake or a strong blast from a garden hose nozzle usually clears the blockage. Verify that downspout extensions are in place and directing water at least 1.8 metres from your foundation, as required by the Ontario Building Code.

Inspect all seams and end caps for gaps or failed sealant. Winter expansion and contraction often breaks sealant bonds, and these gaps will leak during every spring and summer rainstorm. Clean old sealant away and apply fresh gutter sealant (not general-purpose silicone, which does not adhere well to aluminum). This is a manageable DIY repair that costs under $15 in materials.

Finally, examine the fascia boards behind the eavestroughs for signs of rot, water damage, or soft spots. Ice dam overflow during winter often soaks fascia boards, and spring is when that damage becomes visible. Soft or discoloured fascia needs replacement before it fails under next winter's ice load. Fascia replacement costs $12 to $25 per linear foot in Ottawa.
