Perimeter drain failure, root intrusion, and water moving down a slope toward a foundation are the problems we see most often in North Vancouver. The North Shore gets more rain than almost anywhere else in Metro Vancouver, and the properties are steep, heavily treed, and often have older drainage infrastructure. We camera the line, show you what we find, and recommend a repair or replacement based on the actual condition — not a guess.
North Vancouver properties deal with more water, faster, than flat-site homes. A slope concentrates surface and subsurface water against the downhill side of a foundation, and a perimeter drain that might cope on a flat site can be overwhelmed on a slope. Intercept drains uphill of the house, surface swales, and a properly functioning perimeter drain together are usually what it takes to keep a North Shore basement dry through the wet months.
The North Shore is known for its large conifers and mature landscaping, and those trees send roots long distances seeking moisture — straight into drainage and sewer lines. Root intrusion is a recurring cause of blocked drains and failed perimeter drains here. We camera the line to see whether the roots have just entered (cleanable) or have come through a structural failure (needs repair or replacement).
Water in a basement is rarely just one problem. It can be a failed perimeter drain letting groundwater in at the footing, a crack in the foundation wall, or a waterproofing membrane that has broken down over decades. We start with a drain camera inspection to see what is happening inside the pipe, then determine whether the fix is a wet basement repair, basement waterproofing with an exterior membrane and drainage board, or damp proofing of the foundation wall to stop moisture wicking through the concrete. For older North Vancouver homes with original drainage, the answer is often a combination of drain repair and waterproofing — and we show you the camera footage before recommending anything.
Most people never think about their drainage system until it stops working. Here is what a complete system looks like — and where water goes when everything is doing its job.
Rain on roof
Gutters collect it
Downspout
Carries it down
Membrane
Protects the wall
Drain rock
Filters the water
Perimeter drain
Collects groundwater
To sump/storm
Discharged safely
A working drainage system moves water off the roof, away from the foundation wall, and out to a safe discharge point — before it can build up against your foundation.

Before
AfterA wet basement with water at the floor joint — the original perimeter drain had collapsed. We replaced the system and it's been dry through every storm since.

AfterA soggy yard where the downspout dumped onto the lawn. We tied the downspout underground, ran a French drain along the foundation, and the yard dried out within a week.
These are the services we are most often called for in North Vancouver. Each links to a page with more detail on what is involved.
For each of the services below, we have a dedicated North Vancouver page covering what the work involves, what the local conditions mean for that service, and answers to common questions from homeowners in North Vancouver.
My North Vancouver basement leaks every winter. Is it the perimeter drain?
On a sloped, high-rainfall property with an older perimeter drain, that is the most likely cause — but we inspect to confirm. The camera shows whether the drain is silted, root-infested, or collapsed, and whether a targeted repair or a full replacement is needed.
Can trees on the slope above my house damage my drains?
Yes. Roots travel downhill seeking moisture and enter drainage pipes through joints and cracks. If you have mature trees uphill of your drainage lines and recurring blockages, root intrusion is a likely cause. A camera inspection confirms it.
Tell us what is happening and where. We will call you back the same business day to discuss the problem and arrange an inspection if needed.
