A neighbour replaced theirs and we were impressed with the results. We contacted Mark and he came to our home on the weekend to fit our schedule We agreed on the contract and today his employees came at 7:30 AM to start the work. They finished this afternoon and my wife and I are very Pleased with the results The workers cleaned up and took away the old eaves As our old eaves had leaves in them from the trees, the leaves fell on our grass. The workers blew all the leaves away too Phenomenal service Phenomenal product Phenomenal pricing Highly recommend this company Give them a call You wont be disappointed" > Source: Anonymous (5.0, via HomeStars) > "Terrific service, from first call to last exchange. Good quote, with smart rationale for bigger eavestroughs. Good follow up. Was impressed with the speed of response and speed of job completion. A great company with great service. You won't go wrong with them." > Source: Anonymous (5.0, via HomeStars) > "I wasn't sure what needed to be done with my father's roof and the most important thing to me was finding someone I could trust. The roofing scene can be tricky to navigate. I've had bad luck in the past. Ontario Downspout Services had been recommended by a neighbour. Harvey answered the phone and he was a calming and thoughtful soul who started the whole process on a promising note. Mark was awesome. He arranged to meet up with me in record time to discuss the project. The terms were fair and the contract was thorough. We figured the job would be 2 days... 3 at the most. The whole thing was done in less than one day. The crew were ninjas. Within a matter of hours we had a fabulous new roof and eaves and downspouts and the other bits that I can't name. And they left the place spotless. I can't recommend these guys highly enough." > Source: Anonymous (5.0, via HomeStars) ## Trades Plumber, Building inspector, Cleaner, General Contractors, Guttering specialist, Handyman, Roofer ## Awards & recognition - Best of HomeStars winner (2025) - HomeStars Best of the Best winner (2025) ## What we checked, and when _What MyTrustedTraders independently checked for this business (verified items only):_ - Review volume: MyTrustedTraders shows 344 public reviews on this profile.

Out-of-hours overcharging and 'while I'm here' add-ons are common complaints. - Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemized quote (parts and labour separately) before agreeing to major work. - Gas work is licensed separately from general plumbing in every province. Make sure anyone working on a gas appliance or gas line holds the gas certification your province requires, and ask for proof of that certification before they start. - Trade licensing in Canada is set by each province or territory. Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire. - A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay. ## Contact - Phone: (416) 558-9231 - Website: https://ontariodownspoutservice.com/contact/ --- Source: MyTrustedTraders, https://ca.mytrustedtraders.com/traders/ontario-downspout-service Real public evidence only: every figure traces to its named source.
