Clogged eavestroughs are the single biggest cause of basement leaks, ice dams, fascia rot, and foundation water damage in Ottawa homes. With heavy seasonal leaf-fall from mature maples and oaks, plus shingle granules and silver-maple seeds, most Ottawa homes need eavestrough cleaning at least once per year (twice for treed lots). This page covers what professional eavestrough cleaning includes, 2026 pricing in Ottawa, when to schedule, gutter guard options, and how to vet a reliable eavestrough contractor.
A proper Ottawa eavestrough cleaning is far more than blowing leaves out of the gutters. A thorough service protects the entire roof-drainage system and catches small problems before they become expensive ones.
A complete service includes hand-removal of leaves and debris from every gutter run (not just a leaf blower pass), flushing each downspout with a hose to confirm flow, inspecting all hangers and brackets for looseness, checking fascia and soffit for rot or wasp and bird nests, photo documentation of...
Steer clear of 'spray-and-pray' providers who only blow gutters with a leaf blower and skip downspout flushing and inspection. They leave compacted debris jammed in elbows and underground drains, and they miss the loose hangers and early fascia rot that an inspection would catch. The value of profes...
While the crew is on the ladder, they have the best possible view of your roof edge, fascia, soffit, and gutter slope. A good company treats every cleaning as a mini roof-drainage inspection, flagging sagging runs, separated seams, rusted spikes, and early rot with photos so you can fix a $40 bracke...
Pricing scales with home height, roof complexity, and tree load. In 2026, a single-storey bungalow runs $135-$195, a side-split or raised bungalow $165-$235, a standard two-storey home (around 2,000 sq ft) $195-$295, and a three-storey or steep-roof home $275-$395.
Typical extras include gutter guard inspection $25-$45, minor hanger re-securing $15-$35 per bracket, downspout extension installation $45-$85, and soffit or fascia spot-repair $85-$250. Many reputable Ottawa cleaners include a 14-day clog-free guarantee — if a downspout backs up within two weeks of...
Beyond home height, your quote reflects roof pitch, the linear footage of gutter, the number of downspouts, accessibility (landscaping, decks, and tight side yards slow setup), and how long it has been since the last cleaning. A bungalow surrounded by mature maples can cost more than a two-storey on...
The prime window is late October to mid-November, after Ottawa's maples and oaks finish dropping leaves but before the first hard freeze locks debris in place. A second cleaning in early spring (April) clears winter shingle granules, ice-dam debris, and nesting materials. Avoid mid-winter entirely — gutters packed with ice cannot be safely cleaned and most contractors will not attempt it. Homeowners on treed lots with mature silver maples should add a mid-summer (June) visit, because silver mapl...
Ottawa's freeze-thaw winters create ice dams when snow melts on a warm upper roof, runs down, and refreezes at the cold eaves. Clogged gutters make this dramatically worse by trapping meltwater that then backs up under the shingles and into the soffit and wall. Clean eavestroughs let early-winter meltwater drain freely instead of pooling and freezing into a ridge of ice at the roof edge. While cleaning alone will not cure a serious ice-dam problem, a clear drainage path is one of the three pilla...
Lasting ice-dam control in Ottawa rests on three things working together: clean, free-draining eavestroughs; adequate attic insulation (around R-60) to keep the roof deck cold; and continuous soffit-to-ridge ventilation to flush warm air. Cleaning is the cheapest and most immediate of the three, and...
A blocked eavestrough is one of the leading causes of water damage in Ottawa homes. When gutters overflow, water sheets down the foundation, saturating the soil and finding cracks that lead to basement leaks — a frequent problem in older Glebe, Hintonburg, and Vanier homes with aging foundations. Overflow also rots wood fascia and soffit, stains siding, and during winter feeds the ice dams that push water under shingles. The cost of an annual cleaning is trivial compared with foundation waterpro...
A single overflowing season can rot a run of fascia ($300-$800 to replace), saturate a foundation enough to trigger a basement leak ($3,000-$15,000 to waterproof), and feed ice dams that lift shingles and stain ceilings. Against those numbers, two cleanings a year at well under $600 combined is one ...
Gutter guards reduce — but do not eliminate — cleaning frequency. Quality micro-mesh stainless guards, at roughly $7-$12 per lineal foot installed, cut cleaning frequency by 60-80%, but fine debris like pollen, shingle granules, and silver maple seed husks still accumulates and the system needs periodic checking. The best return is on two- and three-storey homes on treed lots, where each cleaning is expensive and risky. Avoid cheap foam inserts and plastic-grate guards, which clog from the insid...
Bungalow $135-$195, side-split or raised bungalow $165-$235, standard two-storey $195-$295, three-storey or steep-roof $275-$395. Add-ons like hanger re-securing ($15-$35 each), downspout extensions ($45-$85), and gutter guard inspection ($25-$45) are extra. Treed lots may carry a debris-volume surcharge.
At minimum once per year, in late October to November after leaf drop. Twice per year if you have mature maples, oaks, or silver maples — add an April spring cleaning and possibly a June visit for silver maple seeds. Newer subdivisions with young trees may manage with one fall cleaning.
On a single-storey bungalow with stable ground access, yes, using a quality A-frame ladder and a spotter. For two- and three-storey homes, hire a pro. Ontario requires Working at Heights training for work above three metres, and gutter-cleaning falls are among the most common serious home injuries.
Quality micro-mesh stainless guards ($7-$12 per lineal foot installed) reduce cleaning frequency by 60-80% but don't eliminate it — pollen, granules, and fine debris still accumulate. They offer the best return on two- and three-storey treed lots. Avoid cheap foam and plastic-grate guards, which clog internally and can worsen ice dams.
It's one of three key factors. Clean gutters, plus adequate attic insulation (around R-60) and clear soffit-to-ridge ventilation, together dramatically reduce ice-dam formation. Cleaning alone helps by keeping a drainage path open, but it won't fully solve ice dams if the attic is under-insulated or poorly ventilated.
