Ontario Downspout Service

Absolutely fantastic experience! Needed the roof redone and the gutters replaced. Mark and his father responded quickly to the request for a quote, came over, walked me through the process and the associated costs, and explained it all in detail. Work was done quickly, safely, efficiently and most of all, done well. Mark is very thorough and kept in contact throughout the whole process. Polite, professional, and friendly, I'd recommend this company to anyone needing to get work done.

This company is superb! The response time is immediate, and they resolved our problem completely. We cannot praise them highly enough!

Mark was amazing from start to finish. It was clear from the beginning he was extremely knowledgeable. It was also important to me that he did not sub-contract his work. He was on site everyday and the project was completed on schedule. He changed my roof and all my aluminum. The eavestroughs are much larger and are handling all the water from the roof. I would highly recommend Ontario Downspout Service Inc. Thank you again.

We had a damaged downspout and had ODS provide a quote quickly by phone with some pics, and they came over 3 days later to install the new downspout, on a sunday morning, as we had communicted that we needed this replacement urgently with april showers in full force. They even added an extension to help drain water more thoroughly. We didn't pay as much as I thought it would cost. Work took less than an hour. Would very highly recommend!

Mark Stone's team was amazing. They replaced my downspout with a brand new one within 24 hours of me calling them. Excellent workmanship. Fairly priced. A real pleasure to work with. I highly recommend them to anyone. Thank you Mark for making this a stress-free experience.

I needed an emergency roof repair and Mark and his crew came immediately. He was very easy to deal with. I would highly recommend this company and would definitely use them again in the future. Thank you again Mark.

Mark and his team at Ontario Downspout Service (ODS) are true professionals.My wife and I had been living through a nightmare scenario with our rooftop terrace which had leaked through all 4 floors of our townhouse. We had repeatedly tried to fix our leak over the previous year with other contractors to no avail.We engaged ODS to replace our flat roof membrane and scupper which had been the source of the leak. Mark navigated a very complex scenario with adjoining neighbours to install our new roof. ODS even installed a custom scupper that allowed for increased water volume.We have had heavy rainfall since then and our water issues are finally solved. Thanks Mark for saving us!

Dealing with Mark from start to finish was amazing. He was helpful and clear with his recommendations. He showed up on time and the work was completed quickly and the clean was impeccable. Would definitely use them again and would highly recommend them. Thank you again Mark.

Mark and his team arrived on time, were punctual, professional and provided advice where needed. There were no surprises.Very happy with my new eaves and downspouts. Highly recommended.

Working with ODS was such a pleasure. We had such a hard time finding a company that we trusted to replace our roof for a reasonable price and quality product. Luckily our neighbour was using ODS and we met Mark who showed us the project he was working on and we felt instant credibility. So glad we decided to work with them and would recommend in a heartbeat.
