Drainage & Plumbing in Dunbar-Southlands Vancouver
Need a plumber in Dunbar? Dunbar-Southlands is bordered by West 16th Avenue to the north, the Fraser River to the south, the University Endowment Lands to the west, and Mackenzie, Quesnel, and Blenheim Streets to the east. The neighbourhood is centered on Dunbar Street, and the Southlands portion south of Marine Drive sits in the Fraser River floodplain. The Musqueam Indian Reserve is encompassed by the region, with archaeological evidence showing First Nations settlement going back to 400 BC. In 1908 the land was owned by the CPR and was part of the now-defunct Municipality of Point Grey - which merged with the City of Vancouver in 1929.
The first major land development happened in the mid-1920s after three streetcar routes reached the area by 1927. Many of those original homes still stand because West Point Grey's 1922 zoning required them to be built at the back of their lots. The Dunbar Theatre has operated since 1935. Pacific Spirit Regional Park runs along the western edge with 55.5 km of trails, and the 2,000-year-old Camosun Bog sits inside the park - long revered by the Musqueam people as a portal to the spirit world. Four golf courses are nearby: Musqueam Golf, Point Grey Golf Club, Shaughnessy Golf, and Marine Drive Golf Club. The Dunbar Community Centre and Vancouver Fire Hall No 21 anchor the local services. Almost every pre-1960 home in Dunbar has clay perimeter drains, cast iron stacks, or galvanized supply lines aging out together. Ryan picks up and we camera every line before we quote.
What Dunbar Homeowners Are Dealing With
Dunbar-Southlands is one of the oldest established west-side neighbourhoods. Most of the housing falls in the 1925-1955 window with newer infill, so drainage and supply systems are aging out together. Add the Pacific Spirit Park watershed and the Fraser River floodplain in the Southlands and you get the patterns we see every season.
- Failed clay perimeter drains on 1925-1945 Dunbar character homes. The Tudor-revival and Craftsman character homes built across Dunbar in the mid-1920s through 1940s were built with clay drain tile that is now 80 to 100 years old. Most are cracked, collapsed, or packed with root mass from the mature street trees and the Pacific Spirit Park watershed to the west. Wet basements and standing water against the foundation in fall and winter are the symptoms. Camera inspection confirms condition before we quote.
- Root intrusion from Pacific Spirit Park and mature street trees. Properties on the west side of Dunbar back onto or are near Pacific Spirit Park's 55.5 km of forested trails. The root systems from park trees and the mature street trees throughout the neighbourhood travel deep and find cracks in old clay and cast iron pipes. Annual root blockages are routine. Trenchless lining seals cracks permanently.
- Cast iron drain stacks corroding from the inside. Pre-1955 Dunbar homes typically have original cast iron stacks in their 70th to 100th year of service. Slow drains on every floor and sewer smells in basements are the signs. Section replacement is often the right call.
- Galvanized supply pipes choking off pressure. Pre-1960 Dunbar homes often still have galvanized supply lines that have been corroding inside for 80 years. Low pressure at every tap and rust-coloured first-draw water are the symptoms. Replace with copper or PEX. See pipe replacement.
- Sump pump and floodplain drainage in Southlands. Properties in the Southlands portion south of Marine Drive sit in the Fraser River floodplain. Drainage conditions are different from the rest of Dunbar - higher water table, equestrian-zone lots, and seasonal river flow. Commercial-grade sump pumps with battery backup are essential. See sump pump.
- Trenchless is the right call on Dunbar lots with mature gardens. Dunbar properties have established landscaping that took decades to grow in. Trenching destroys it. We use trenchless pipe lining and pipe bursting wherever site conditions allow.
