Our Services

We are drainage experts with decades of experience who work towards ensuring your entire home’s drainage system is working optimally. We understand the importance of having the exterior of your home look great and we offer a wide range of colours and materials for all of your home’s needs.

  • Eavestrough & Downspout

    The main advantage of installing 6’’ heavy-gauge aluminum eavestroughs is its capacity to handle heavy rain downfalls, eliminating overflow. Moving from a standard 5’’ system to a 6’’ system will allow the installation of larger downspouts and minimize the risk of severe water damage.

  • Soffit & Fascia

    The aluminum-vented soffit is installed to bridge the gap between your home siding and the roofline. We then install custom, maintenance -free aluminum fascia to lock in the soffit and to ensure that the underlying wood is completely protected.

  • Siding Installation

    Siding is installed to protect your house and its foundation from the elements. Before the installation begins, we perform an inspection to ensure the house is adequately insulated. With the wide variety of siding options, any aesthetic can be achieved.

  • Roofing Installation

    We will do an in-depth inspection to determine which type of roof system and product is right for you. Budget, aesthetics and functionality will all be taken into consideration. All of our roof installations will last a minimum of 20 years.

  • Specialty Work

    We can incorporate unique, timeless accent pieces such as a lead-coated copper bay window roof, which will make your house “pop”. We can also apply this theme to your entire house and choose materials such as a slate roof with copper flashing.

  • Emergency Service

    Ontario Downspout Service prides itself on excellent customer service. We will be here for you when you need us the most. To avoid a crisis, we strongly encourage regular maintenance of your roofing, siding and eavestrough systems.

New Roof!

I wasn't sure what needed to be done with my father's roof and the most important thing to me was finding someone I could trust. The roofing scene can be tricky to navigate. I've had bad luck in the past. Ontario Downspout Services had been recommended by a neighbour. Harvey answered the phone and he was a calming and thoughtful soul who started the whole...

Mark and his crew did a great job replacing the flat roof on my house and dealing with a leak I had into my living room by replacing a strip of roof and eaves trough along a side of my house in an awkward narrow area between my house and my neighbours. Mark shared photos as they removed the old materials so I could see the problem areas and understand how the...

After comparing a few quotes, I went with Mark and Ontario Downspout. His initial assessment was incredibly thorough and left me confident in my choice. A few weeks later, his crew arrived to tackle the job over the course of a weekend. They did fresh eaves, soffits, and did a great job freshening up the back exterior of my house -- changing old, rotting wood into fresh...

I found Ontario Downspout Service on Homestar and I am so glad I did! I initially got Mark to give me an estimate to replace one of the downspouts on my roof that became detached. He was the only one that gave me a quote right away and came over very quickly to fix it. While on the roof, we got talking and he inspected my roof and gave me an estimate. The work was...
