Drainage and Plumbing in West Point Grey Vancouver
Need a plumber in West Point Grey? This is 4.45 square kilometres bordered by 16th Avenue to the south, Alma Street to the east, English Bay to the north and Blanca Street to the west. North of West 4th the ground drops steeply to Locarno Beach.
Water here arrives from above and from underneath. We camera every line before we quote, and you keep the footage.
Why the ground here stays wet after the sky clears
West Point Grey sits on a lid of slowly permeable glacial till over a thick, porous layer of Quadra sand. Running through that sand are thin clay layers that are also slowly pervious, and the GVRD study of the Point Grey cliffs is blunt about what they do. Those clay layers block accumulated groundwater and push it sideways toward the cliff face. Geologists call the whole arrangement a perched aquifer.
That is the difference between this neighbourhood and a flat inner city lot. Water does not simply drain down and away. It travels laterally through sand until a clay lens stops it, and on a north facing slope the direction it travels is toward the houses below. A sump still running two days after the rain stopped is normal on this slope rather than a red flag.
The creeks say the same thing. Canyon Creek has its headwaters in Pacific Spirit Regional Park and its lower end used to run through an underground pipe before discharging into Burrard Inlet. The City dug it back out at Spanish Banks Beach Park, with construction through fall and winter 2024 and completion in spring 2025. Spanish Bank Creek came back up in 1999 and Salish Creek in 2012, and the Jericho Lands masterplan will daylight two more historic creeks on that site. Every one of them was somebody’s storm pipe first.
One thing worth saying plainly: none of West Point Grey is inside the City’s designated floodplain. We checked the dataset against this neighbourhood and it returns nothing. The water problem here is groundwater and slope, not river flooding.
Two eras of house on the same block
Pull the build year on every parcel in West Point Grey and the picture is not one story, it is two. 1,362 parcels, 40.0% of them, went up before 1940, and the 1920s alone account for 732 of those. By 1950 the count is 1,656, or 48.6%. Two houses out of five on these streets predate the Second World War, and the first Point Grey zoning bylaw in 1922 allowed only detached houses and their outbuildings.
Then there is the other era. 643 single family parcels, 18.9%, were built between 1978 and 1998. Poly-B was going into Canadian homes across that whole window. It is usually grey and it carries PB2110 or CSA-B 137.8 stamped on the side, and insurers treat it as a water damage risk rather than a cosmetic problem. Across all parcel types the number in that window is 1,126 of 4,326, about a quarter of everything with a date on it.
We are not going to tell you what is buried at your address because nobody has surveyed the private side of this neighbourhood. What the build year does tell you is what to look for. A pre-war house gets the perimeter camera first. A late 1980s house gets somebody reading the supply pipe in the mechanical room before anyone talks about pressure.
The pipe the City owns is documented. Inside West Point Grey there are 1,317 sewer main segments and 247 of them, 18.8%, still carry rain and sewage in one pipe. That remnant is spread right across the neighbourhood rather than sitting in one pocket. Vitrified clay is still the single most common main material with 477 segments, concrete is second, and PVC is what goes back in. There are 1,265 City catch basins.
What Vancouver customers say
Ryan was great! My landlord called him to fix my blocked kitchen sink. He showed up the same day (on a Sunday) and fixed the problem. He even cleaned the sink and dried up all the water that had leaked before he got there. And he was very careful coming in and out of the house so my cat wouldn’t get out. I’d definitely recommend him.
Ryan is INCREDIBLE. He has been responding to all of us (four houses and families!) affected by a sewage back up. This is all on Boxing Day and beyond, in terrible weather full of ice, cold and rain. He is so knowledgeable, and knew what was needed right away. Just the top of his field I am sure. As well as that, he is incredibly calm, respectful, kind and fair. I am truly amazed by this person's capacity and competence in combination with his noble, calm presence in the face of a real mess. Thank you Ryan, so very much!
I had very positive experience with Mamba Services, Ryan was amazing to work with and took care of my drain issues in no time. He arrived on time, was very professional and efficient in carrying out the work. What impressed me was how honest he was in recommending needed repair. He was very patient in explaining the different options. I will certainly call them for future projects.
Had an excellent experience. Ryan was fantastic, it was an after hours call late in the evening and he showed up exactly in the time frame he gave. Took care of the kitchen sink issue within minutes all systems were running like new. Pricing was extremely reasonable, Ryan was patient and explained everything to me while fixing my problem. I would highly recommend this company for any plumbing work.
Ryan was efficient, experienced, and knowledgeable. He was able to squeeze me into his schedule with short notice and wasted no time with my appointment. He arrived on site inspected the issue, and was quickly at work with resolving the problem. I am very pleased with his service and honesty. He provided recommendations that will help assist me in future occurrences.

West Point Grey drainage and plumbing FAQ
Because of what you are sitting on. The Point Grey upland is slow glacial till over deep Quadra sand with thin clay layers running through it, and the GVRD study says those clay layers block groundwater and force it sideways. On a north facing slope sideways means downhill, toward you. A camera on the perimeter tells you whether the tile is still carrying that water away.
Possibly. 247 of the 1,317 sewer main segments inside West Point Grey are still combined, about 18.8%, and they are spread across the whole neighbourhood rather than concentrated in one pocket. We can tell you what runs under your block before we come out.
They do, and this neighbourhood has the trees for it. There are 5,747 City trees in West Point Grey. West 13th Avenue alone carries 113 elms and 115 maples, and the largest elm on that street measures 111.8 cm through the trunk at 4246 West 13th. The City lists tree roots alongside damage and age as the way cracks form and extra water gets into a sewer.
Usually. The City names three renewal methods: open trenching, pipe bursting and pipe relining. Bursting pulls a new line through the existing path from two small pits. Lining seals the host pipe from the inside where it still holds its shape. We camera first to confirm which one your line can take.
Worth a look. 643 single family parcels here were built between 1978 and 1998, and Poly-B went into Canadian homes across that whole window. It is usually grey and it carries PB2110 or CSA-B 137.8 stamped on the side. Insurers can decline it, price it higher, or raise the water damage deductible, so it is worth knowing what you have rather than assuming.
No. We queried the City’s designated floodplain dataset against this neighbourhood and it returns nothing. The eight polygons in that dataset are Fraser River and False Creek and Burrard shoreline scenarios. Your water problem here is groundwater and slope, not the river.
You maintain the sewer lines on your property up to where they meet the City’s connection. Your contractor contacts the City for permits before the work starts and books the inspection when it is done. Extra water gets into the system through cracked pipe, leaky joints, and roof and foundation drains that were wrongly connected to the sanitary line.
It is a 90 acre site owned by the Musqueam, Squamish and Tsleil-Waututh Partnership with Canada Lands Company, and Council approved the Official Development Plan on 22 April 2025. The plan is around 13,000 homes with 30 acres of park, new storm and water infrastructure, and two historic creeks daylighted across the site. For neighbours it means the drainage network on that ridge is being rebuilt rather than patched.
Yes. West Point Grey carries 52 buildings on the Vancouver Heritage Register, 11 of them Group A, including Hastings Mill Store at 1575 Alma Street, Aberthau at 4397 West 2nd Avenue and Brock House at 3875 Point Grey Road. On a listed house we look at trenchless first, because the least invasive method is usually the only sensible one.
No travel surcharge. Point Grey, Dunbar, Kerrisdale and the University Endowment Lands are all the same pricing as anywhere else in Vancouver.
