What do Ottawa contractors charge for adding a second downspout run to an existing eavestrough?

Adding a second downspout to your existing eavestrough system in Ottawa typically costs between $200 and $600 per downspout, depending on the complexity of the installation, material matching, and whether underground drainage connections are required.

The cost breakdown includes several components that Ottawa contractors price separately. The downspout itself runs $40 to $80 for standard aluminum, while copper downspouts cost $120 to $200. Fascia and soffit cutting for the new outlet adds $75 to $150 to account for precise measurements and clean finishing work. Most of the cost comes from labour, as contractors need to cut a new outlet hole in your existing eavestrough, install the drop outlet fitting, and secure the downspout with brackets every 6 to 8 feet down the wall.

Underground drainage connection significantly increases the total cost to $400 to $800 per downspout in Ottawa's challenging soil conditions. Ottawa's clay-heavy soil requires careful excavation, and contractors must dig below the 1.2 to 1.5-metre frost line to prevent frost heave from damaging the connection. Many Ottawa homes built before 1980 lack proper foundation drainage, making a new downspout an opportunity to improve overall water management around your home.

The optimal time for this work in Ottawa is May through October when ground conditions allow for any necessary excavation. Contractors often recommend adding downspouts during spring when winter ice damage becomes apparent, or in fall before the next freeze-thaw cycle. If your existing eavestrough system overflows during heavy summer thunderstorms or shows ice dam damage from insufficient drainage capacity, a second downspout can dramatically improve performance.

Material matching is crucial for a professional appearance and proper function. Your contractor should use the same gauge aluminum and colour as your existing system. Seamless downspout sections look cleaner than pieced-together joints, and most Ottawa contractors can form custom lengths on-site. The new outlet should be positioned to optimize water flow – typically at the opposite end of a long eavestrough run or at a natural low point where water tends to pool.

Consider the drainage endpoint carefully before installation. The Ontario Building Code requires downspout discharge at least 1.8 metres from your foundation. In Ottawa's clay soil, surface drainage often performs better than attempting to tie into existing underground systems that may be compromised by decades of freeze-thaw cycles. A simple splash block or decorative drainage feature can be more reliable and less expensive than underground connections.
