Harvey and Mark are real pros. They tell it like it is and if something isn't done to their high standards they definitely will let you know.

Mark came with his team and fixed the roof. It took them about a day and the quality looks great.

Will absolutely recommend them to anyone and will use them again if needed in the future.

Thank you!

This company is great to deal with and we thought we had posted our review! Oops... it was saved in our reviews page! Mark and his team were professional and respectful, skilled and courteous, and are great at what they do! Our whole roof, extension, shed, eaves, soffits, etc. and wood underneath had to be redone. The work was completed in 2 stages - as our eaves 'went first' (AUG 2016) - and so after 5 quotes we settled on this company. When the windstorm happened in the Fall of 2018 and our shingles came off and flew all over the neighborhood, we called Mark (as we knew we'd hire him again when it was time for our roof to be replaced). He replied immediately and patched the roof as a temporary repair - again great job - until we could book a date for the roof. December of 2018, he and his crew came and installed a beautiful roof to go with our new eaves. The quality of the materials and the craftmanship of the work was fantastic! Highly recommend!

It was easy dealing with Mark and Harvey. They kept me updated with regards to when the job could be done, and on the day of service, they called ahead and gave an accurate ETA.

Harvey responded to our request promptly, and Mark showed up when he said he would. Mark immediately applied a temporary fix, and then shortly resolved the leak by replacing an inappropriate vent. Mark gave us a thorough report on the condition of the flat roof. It will last a while but when it's time to replace it I will definitely call Ontario Downspout. Thanks Mark and Harvey!

Great guys, great work!
Courteous, efficient, timely, clean & professional, everything you could want in this kind of service.

Mark and Hector were in and out in 2 days. The new eves look great and the downspout locations were carefully placed to get water away from the house.
Where necessary the bottom ends are hinged to allow access down the sides of the house. Didn't even know there was such a thing.
Everyone we interacted with entirely professional. We would recommend Ontario Downspout. Service without hesitation.

Mark and his skilled crew rescued me from my recent diaster with another contractor. Nice new gutters and better downspouting fixed all my drips and flooding. Highly recommended-Thanks from P Sugar

Mark Stone and his crew replaced all the downspouts on our three story Edwardian semi-detached home. For several years, heavy rains had resulted in chronic overflows in our existing downspouts. Because the company also does roofing, they were also able to replace a portion of our roof that urgently needed it. They served our needs very conscientiously and well. The work was done professionally and efficiently; they use excellent materials and have a lot of experience. We would recommend them. - P&J

Mark and Harvey are an absolute delight to work with. We had some issues with our eaves and downspout. They were able to identify the issues and the work that they did is top quality. I've recommended Ontario Downspout to my neighbours without any hesitancy. If you want the job done right this the company you should choose. Thanks guys, we couldn't be happier. -Jon C.

Mark and his crew have completed a very high quality work in replacing our eavestroughs and downspouts. They also installed high quality aluminum leaf guards.
Additionally they replaced the front balcony flat roof and made the drainage more effective.
The work was completed in a timely manner. We were also very happy with the clean up of the site after they completed their work.
A very professional family owned company that we would recommend highly for similar work.
