Ontario Downspout Service reviews (344)

Completely replaced all eaves, back low slope roof plus shingle roof and porch shingles. Did an amazing job, clearly committed to quality and project communication.

Great work! Very professional and knowledgeable. We are very happy with their work. Thank you!

I am a repeat customer because of the excellent and consistent client service. The roof of our house was significant damaged from this year’s windstorm. As soon as I contacted Mark, they were able to come to our house that same weekend and make the necessary temporary repairs. Mark and his team followed up with a complete roof replacement - they were efficient, completed the job in two days, and we were very happy with the results. They obviously care about their workmanship and it shows. Thank you to Mark and Harvey - we highly recommend you!

We had to fix shingles that had come off our roof . It is difficult to get up to the roof as it’s quite high and the shingles were missing from an awkward spot. We spoke to Mark and he was so responsive and came to look at it ASAP and was able to make a fast assessment and was able to fix my issue while handling other jobs as well. Mark and his crew werr amazing and I would highly recommend his team.

Very friendly, professional people. They did the whole job - including removal of the existing one - in less than 4 hours. Didn’t try to oversell me.

Job was done fast, without any unnecessary additional costs added on. The job was quick, professional and of a high quality. Recommend to anyone.

We contacted the company to replace the roof of our home. Mark Stone and his team completed the work to our satisfaction. The team worked well together and paid careful attention to the details of the work. The debris were removed and the property left tidy. Thank you, Mark and your team, for a job well done!

As a result of the May 4 windstorm I had trouble finding a roofer. I was met by busy signals and full message boxes. Ontario Downspout Services impressed me right from the start. Even though their message box was full and I couldn’t leave a message, Harvey called me back (just based on seeing my number on call display knowing I probably needed help!). That is true customer service! And my interaction with the company only got better. They promptly came out and put a temporary waterproof barrier on my roof to minimize any problems until they could schedule my roof replacement. Unfortunately the weather resulted in some interior damage, but when I called Mark to see if my repair could be moved up, he was able to shift things around to do my roof right away. The work that Mark and his team did was excellent. They worked very efficiently and took great care of my property. Harvey and Mark are very professional, personable, caring and courteous. When posters say they treat you like family, it is true. I was so impressed with my entire experience with the company that I would definitely recommend them to others and call them as my “go to” company in the future with any roofing related work I need.

Working with both Harvey and Mark was a pleasure. Despite their busy schedules, they were able to accommodate us and get the work done much sooner (We had water leaking into our basement). They replaced both our eavestrough and downspout. Their crew was friendly and professional. They arrived as scheduled, were respectful of our property, and cleaned up thoroughly. For our next roofing job, we will definitely be using them again.

Harvey and Mark were a pleasure to work with, and despite their busy schedules, managed to accommodate me much earlier than anticipated due to water seeping into my basement. They replaced my eavestrough and downspout that was installed by a so-called 'professional'. They explained the process, arrived with a friendly and courteous crew, and my new eaves and downspout with diverter looks great! I would highly recommend them and will be using them for any future services I may need.
