Ontario Downspout Service

City of Toronto required mandatory downspout disconnection. Work was completed before schedule and in a very professional manner.

Mark and his team did an amazing job - very quick and efficient. They made sensible recommendations to us about the work that needed to be done. We found them very trustworthy and reliable, and the quality of work was excellent. We would definitely recommend them to others!

I had my eaves cleaned and downspout disconnected last year. Harvey was very quick in responding to my inquiry and answered all my questions. When work date was finally confirmed, Mark and his team were professional and completed the job with no issues. I would definitely recommend their services.

A pleasure doing business with this father and son team from beginning to end. Harvey and Mark were both very friendly and job was completed in a timely manner as promised. I would highly recommend them and will for sure contact you when it is time for a new roof at my mom's place and mine.

I used Ontario Downspout Service to replace my roof and eavestroughs. Mark and his team were quick and conscientious. The quality of their work is fantastic, but I was most impressed by Mark's commitment to customer service. He went above and beyond to ensure I was satisfied with the work, and was available to answer questions/address my concerns before, during, and even after the job was completed. I highly recommend their services.

Mark arrived right on time with a very cheerful smile and friendly hello and announced he and his team were here to do the downspout disconnect. They got to work and were finished in no time. He took me over to see the work and explain any info. concerning care of the downspout extension if heavy winds came up. It was a job well done and it was a pleasure dealing with Mark and this company. If I have any further work in this category, I will be sure to call Mark.

Top notch service. delivered as promised. eaves were non-functioning before, Mark came and re-installed new ones that are functioning and look great. great company, family run business. They promised a date and were able to deliver new eaves before the date promised. highly recommended

Let me start of and saying that I'm very picky guy. Finding contractors for me is a hard task. So when I found Mark at Ontario Downspout Service I was impressed from the get go. I also was extremely happy with their work to detail. I had my house in Mississauga completely redone with eavestrough, soffit and fascia. The work was done with perfection. I had several leaks before. So bad that I couldn't leave my windows open after it rained. Now not one drop leaks. THANKS Mark!!
I highly recommend Ontario Downspout Services. You won't be disappointed. Mark now is like family to us.

Mark was extremely reliable, punctual and sincere about all work being performed.
Very professional business owner, upfront and honest.
They were thorough in all areas and and work completed was excellent overall.
No comparison with the previous installer that left us with problems.

Highly recommend Mark and his team.

We recently replaced the eavestrough and disconnected the downspouts of our home. The end-to-end process was well managed by the father and son team, Harvey Stone and Mark Stone. The process started with Harvey Stone responding very quickly to our inquiry and he visited us and provided advice and an estimate, which we accepted. The installation was managed by Mark Stone and his crew, who went to work immediately and I could see their professionalism and attention to detail in what they were doing. They left the impression they were committed to doing a perfect job and ensuring customer satisfaction. Mark and his crew succeeded. My wife and I are very pleased with the quality of their work. This afternoon we had a thunderstorm and their work held up well. Keep up the good work, and thank you Harvey, Mark and the crew for a job well-done.
