Ontario Downspout Service reviews (344)

I called Mark in a panic on a Friday afternoon when I noticed that the downspout had disengaged from the eavestrough and was leaning precariously. He came to my home within an hour and had everything fixed and secured quickly. I will happily use his services again.

Thanks to mark and his team for the professsional and meticulous work they did on our home

Mark was nothing but professional and timely. From the time I called him for an estimate until the time the work was completed it was within a week. My roof was in desperate need of repair as it was starting to leak. Mark and his team "rebuilt" my roof and left my yard exactly how they found it. Thanks Mark.

Mark and crew did a great job. They arrived when promised, were efficient and totally finished our large job by the next morning, and left the area spotless. Couldn't have asked for more.

Excellent Customer Service! Roof repair was handled promptly and efficiently. Representatives from Ontario Downspout Service Inc. were: Harvey and Mark Stone Both of these fellows spoke to us in a confident and reassuring manner. The extent of roof damages were clearly outlined to us as well as exactly what was required to resolve our issue. After repairs were completed a picture was emailed to us, indicating nature and location of damage. List of materials used to complete work was also provided. Harvey and Mark both understood our concerns with winter approaching and agreed that this work should be completed now rather than waiting until spring time. Roof repairs were completed the following day, without any complications. Good news. Harvey and Mark were both pleasant and professional, offering advice and direction every step of the way. With all of this happening a week before Christmas, we were grateful to have found Ontario Downspout Service Inc. Many thanks. Anne Toronto M4G 1V7

Roof and Eavestrough replacement. Mark was excellent. Would highly recommend them to anyone, on time and work was done quickly and professionally.

Mark and his team worked vigorously and diligently to replace our roof in one day before the winter weather hit. This was the second time we used Ontario Downspout as we had first used them for our eaves and soffits the year before. Once again they were professional and efficient. Mark also came within a day to repair our roof after a major windstorm. He was always available to answer questions or concerns, and ensured to follow through with any requests. . We would recommend this company to anyone needing either service.

I am delighted with the work that Ontario Downspout Service provided! On a very cold November day Mark and his crew arrived at 7:30 am to completely replace my eaves and downspouts. I was so impressed with the conscientious and cheerful manner in which they worked. Their cleanup really impressed me too. My walkways and deck were left in a far better condition than before they arrived. Harvey, you trained your son well and delivered exactly what you promised and more. Thank you so much. Joan Kirsh

Roof and Eavestrough replacement. Mark was excellent. Would highly recommend them to anyone. Will have them back next year to do the siding. Thank you again Mark.

The quoting process was thorough and accurate. There were no hidden cost overruns. Communication with the company was excellent. The installation was timely and the design and products were superior. An experienced company with a real concern for their customers. The new 6" troughs can handle any amount of water.
