What Our Customers Say
James Dean
It was an absolute pleasure dealing with Mark from start to finish. He replaced our roof, soffit, fascia, eaves and all of the rotted wood. He also installed beautiful copper detailing around our front porch. We wouldn’t hesitate to recommend Mark, he truly goes the extra mile for you.
Janette MacAvoy
We received several quotes before deciding to go with Ontario Downspout Service. What stood out to us was Mark’s customer service, attention to detail and transparency. Mark replaced our roof, soffit, fascia and eavestroughs in a timely manner and left the work site spotless.
