I needed a new roof and checked out Ontario Downspout Service reviews. I was impressed and decided to use them, after comparing various companies.
Harvey was professional and prompt with his response to my inquiries, as was Mark.
Mark and his team worked hard and did a fantastic job on the new roof. I had to have plywood installed over my old plywood, as well as new shingles and finally, my chimney needed to be removed. They were amazing and kept the premises clean throughout the time that they were here and did a final clean up at the end.
I would highly recommend this company to anyone looking for a professional and hard working team.

House was built in the 1920s and the downspouts, eavestroughs, and soffits were problematic and probably from the 1980s. Great working with Mark of Ontario Downspout Service: excellent recommendation of colors and materials, and his team completed the installation, including 65 linear feet of fascia board and full clean-up, in 1.5 days. High quality work: drainage issues resolved and compliments from neighbors about the improved appearance.

I am extremely pleased with the work that Mark and his team provided. Not only did the team arrive on time, as promised, they worked hard to deliver and install a great product, efficiently and with excellent attention to detail. I have no hesitation in recommending Ontario Downspout Service. My home now looks refreshed and modern. I Love it! Thank you Mark and Team! Great work!

I was really impressed with the service and the quality of the work done. They were prompt, responsive and took a lot of pride in their work. Really a pleasure to do business with. I would highly recommend them.

I have used this company before at my office and was happy with the work. This time I needed a new roof replaced fast because it was leaking. Mark was very quick to respond to my pleas and put me on the priority list because we had leaks. He does the work himself and he and his team were fast, clean, courteous, and meticulous. They also offer ongoing eaves cleaning so that they guarantee their work. I feel confident that my need for any ongoing work will be answered promptly. Highly recommend Ontario Downspout !

As an interior designer the dated metal work around my victorian semi was due for an upgrade. I found Mark and his team online, and was impressed from the first call, to the finished product. They were responsive, communicative, and clear. They completed the job in less time than estimated, and left the place in a clean condition. It is rare to find trades that are the whole package - but with this team, I had complete faith the entire time. Would recommend this team in a heart beat. Thank you for making my home so much more beautiful, and for going above and beyond.

Had some damaged shingles post-wind storm. Harvey and mark were professional and prompt and were able to do the repair the same day. Very happy with the service and definitely be using this company again.

Mark was great, came to my place on short notice and helped me fix an issue with my downspout, would absolutely recommend!

We are extremely happy with the work Mark and his team did for us. A week after moving into our new home, we discovered a porch leak and frantically called ODS. Mark was able to come to our house the next day, provide a thorough assessment, and fit us in for this urgent job. Mark and his team (shout out to Hector and Carlos) were professional, organized and knowledgeable. Mark communicated clearly and thoughtfully throughout the process, helped us problem solve, made great recommendations, and fitted us with a beautiful new porch roof and gutters! We couldn’t be happier with the results and highly recommend ODS.

We noticed a bit of leaking in our basement bathroom ceiling and realized it was an ice dam buildup. We'd never had that before so I wanted to get it resolved asap. It was 9pm and I found Ontario Downspout Service on Home Stars and it had great reviews. I called the number and Mark was super helpful to take time to discuss the issue, review pictures I sent and suggest a solution, plus he said he could come the next morning. Mark and his colleague came the next morning and melted the ice, removed the old broken downspout and pipe and put a new one in. They were really nice, took the time to explain options. He said because it was temporary until the spring when a better solution could be provided, to let him know if there were any other issues. Unfortunately the horizontal pipe froze again a few days later and he came back at no charge to remove the frozen horizontal pipe and put in a heat cable I bought into new pipe. Mark and his team were great to deal with and fixed everything quickly. Will be using them again for a more permanent solution in the spring!
