It was an absolute pleasure dealing with Mark from start to finish. He replaced our roof, soffit, fascia, eaves and all of the rotted wood. He also installed beautiful copper detailing around our front porch. We wouldn’t hesitate to recommend Mark, he truly goes the extra mile for you.

We received several quotes before deciding to go with Ontario Downspout Service. What stood out to us was Mark’s customer service, attention to detail and transparency. Mark replaced our roof, soffit, fascia and eavestroughs in a timely manner and left the work site spotless.

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.

New Roof!

10/10

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...

Flat roof and eaves

10/10

Mark and his crew did a great job replacing the flat roof on my house and dealing with a leak I had into my living room by replacing a strip of roof and eaves trough along a side of my house in an awkward narrow area between my house and my neighbours. Mark shared photos as they removed the old materials so I could see the problem areas and understand how the...

Eavestrough and downspout replacement

For years our roof was not draining properly. I called Ontario Downspout and got professional advice - first over the phone (using Google Earth to look at the house online), then an in-person inspection. Mark was very helpful in explaining what was need to fix the problem, then scheduling the work at a time convenient for me. The installation was efficient and professional...

Mark is fair and a pleasure to deal with. His crew left my property cleaner than they found it which is rare these days! Would recommend anyone looking for quality services to use Mark and...

Eaves, soffits, and siding done to PERFECTION

10/10

After comparing a few quotes, I went with Mark and Ontario Downspout. His initial assessment was incredibly thorough and left me confident in my choice. A few weeks later, his crew arrived to tackle the job over the course of a weekend. They did fresh eaves, soffits, and did a great job freshening up the back exterior of my house -- changing old, rotting wood into fresh...

Flat roof and siding replacement

I found Ontario Downspout Service on Homestar and I am so glad I did! I initially got Mark to give me an estimate to replace one of the downspouts on my roof that became detached. He was the only one that gave me a quote right away and came over very quickly to fix it. While on the roof, we got talking and he inspected my roof and gave me an estimate. The work was...
