Eavestrough Replacement Cost for a Duplex in Vanier Ottawa

Replacing eavestroughs on a duplex involves some unique considerations compared to a single-family home, and Vanier's housing stock has specific characteristics that affect both the scope and cost of the work. Many Vanier duplexes were built in the 1940s through 1960s, featuring flat or low-slope rear roof sections, shared parapet walls, and original fascia boards that may need attention after 60-plus years of Ottawa weather.

Duplex Eavestrough Replacement Costs in Vanier

For a typical Vanier side-by-side or stacked duplex, expect to pay $2,500 to $5,500 for a complete seamless aluminum eavestrough replacement covering both units. Most Vanier duplexes have 150 to 220 linear feet of eavestrough when you account for the front, sides, rear, and any secondary roof sections over porches or additions. At Ottawa's standard rate of $8 to $18 per linear foot for seamless aluminum, plus downspouts, corners, and removal of the old system, the total falls in that range.

Vanier's older duplexes present several factors that can push costs toward the higher end. Original wood fascia boards on homes from the 1940s and 1950s are frequently rotted, especially on the north-facing and rear elevations. If fascia replacement is needed, add $12 to $25 per linear foot for the affected sections. On a duplex where 40 to 60 linear feet of fascia need replacement, that is an additional $480 to $1,500.

Many Vanier duplexes have flat or low-slope roof sections at the rear, which require different eavestrough detailing than standard pitched roofs. Flat roof drainage typically uses internal scuppers or concentrated discharge points rather than continuous eavestroughs along the drip edge. If your duplex has a flat rear section that drains into eavestroughs, the contractor needs to ensure the gutter can handle the concentrated water flow — this sometimes requires oversized 6-inch eavestroughs or additional downspouts at the discharge points.

Ownership and cost-sharing is an important practical consideration for duplex eavestrough replacement. If you own the entire duplex, you control the full project. If the duplex is a condo or co-ownership arrangement, you will need to coordinate with the other owner. Since eavestroughs serve the entire building, the cost is typically split equally between units or handled by the condo corporation. Getting agreement before hiring a contractor avoids disputes during the project.

Vanier is undergoing significant revitalization, and many homeowners are investing in exterior upgrades that complement the neighbourhood's improving streetscape. If you are replacing eavestroughs as part of a broader exterior renovation including soffit, fascia, and possibly siding, bundling the work with a single contractor saves on setup costs and ensures colour matching. A full soffit, fascia, and eavestrough package on a Vanier duplex typically runs $6,000 to $12,000 for both units combined.

The City of Ottawa's downspout disconnection program is worth knowing about if your duplex currently has downspouts connected to the municipal combined sewer system. Older Vanier properties may still have this legacy connection, and the city encourages disconnection to reduce combined sewer overflow. Redirecting downspouts to discharge at grade at least 1.8 metres from the foundation is typically straightforward to incorporate into an eavestrough replacement project.
