Questions to Ask an Eavestrough Contractor in Ottawa

Asking the right questions before signing a contract separates a smooth eavestrough project from a frustrating one. Ottawa's demanding climate means certain questions are especially important here that might not matter in milder cities.

Start with the essentials that every Ontario contractor should answer without hesitation. "Can you provide a current WSIB clearance certificate?" is non-negotiable — eavestrough work involves heights, ladders, and sheet metal, and you need confirmation the contractor carries active Workplace Safety and Insurance Board coverage. Follow up with "What is your liability insurance coverage?" — the minimum standard in Ontario is $2 million. Ask for proof of both before any work begins.

Ottawa-Specific Questions That Matter

Ottawa's climate demands specific installation practices, so ask questions that reveal whether the contractor understands local conditions. "What hanger spacing do you use?" — the correct answer for Ottawa is 18 to 24 inches maximum. If they say 36 inches, that is a contractor unfamiliar with snow-belt requirements. Ask "What gauge aluminum do you install as standard?" — 0.027-inch is the budget standard, while 0.032-inch gauge offers significantly better resistance to ice damage and denting. Ask which gauge is included in their quote and what the upgrade costs.

"How do you handle thermal expansion on long runs?" is a question that separates experienced Ottawa installers from generalists. Aluminum eavestroughs expand roughly 6 millimetres over a 10-metre run between Ottawa's winter lows and summer highs. Proper installers use expansion joints or leave calculated gaps at corners and end caps. A blank stare in response to this question tells you everything you need to know.

Ask "How many downspouts are you including and what size?" — undersized or too few downspouts is one of the most common problems in Ottawa installations. A typical Ottawa bungalow needs a downspout every 30 to 40 linear feet of eavestrough, and 3-by-4-inch rectangular downspouts handle heavy rainfall far better than 2-by-3-inch. Ask "Where will downspouts discharge and how far from the foundation?" — the Ontario Building Code requires a minimum 1.8-metre setback from foundation walls.

"Does your quote include removal and disposal of the old eavestroughs?" — some contractors quote installation only and charge $200 to $500 extra for teardown and disposal. Get this in writing. Ask "What is your warranty and what does it cover specifically?" — workmanship warranties should be a minimum of 5 years, separate from the manufacturer's material warranty. Ask what happens if a seam leaks or a hanger fails within the warranty period.

Finally, ask "When can you start and how long will the job take?" — a typical Ottawa bungalow takes one day, a two-storey home one to two days. Fall is the busiest season for eavestrough work in Ottawa, so booking early is wise.
