Drain Tile Replacement in Port Moody
When the camera shows your Port Moody home's drain tile has failed throughout — collapsed clay tile, silted corrugated pipe, or a system so old that patching one section just moves the failure downstream — replacement is the only fix that actually solves the problem. In Port Moody, where the sloped terrain concentrates water against downhill foundations, a failed drain tile is not something that fixes itself. We replace drain tiles in homes across Port Moody, from older character homes to 1970s builds, and we show you the camera footage before we ever recommend replacement.
When drain tile replacement is the right call
Replacement becomes the honest recommendation when three things are true: the camera inspection shows the system has failed in more than one area, the materials used originally have reached the end of their service life, and the cost of repeated repairs would exceed the cost of doing it once properly. We show you the footage and explain exactly which of these applies to your home before quoting a replacement.
What a drain tile replacement involves
A full replacement means excavating a trench around the foundation down to the footing, removing the old pipe, and installing a new perforated drainage system. The build-up is specific: a bed of clean crushed gravel, the perforated pipe with the holes facing down, more gravel around and over the pipe, and filter fabric wrapping the gravel to keep fine soil from migrating in and clogging it over time.
The new drain connects to a sump pit (with a pump if the property does not have a gravity storm connection) or to an existing storm sewer. We compact the backfill and restore the surface — concrete, pavers, lawn, or garden — as close as practical to how we found it.
Working around occupied Port Moody homes
Most replacements are done on homes people are living in. We plan the excavation in sections so the property remains accessible, we shore up where needed, and we keep the site safe and contained. The work is noisy and messy for a few days, but a properly replaced drain tile protects the foundation for decades — and the alternative, repeated basement flooding and potential foundation damage, is more disruptive and more expensive in the long run.
Drain tile replacement considerations for Port Moody
Drain tile replacement in Port Moody is shaped by the age of the housing stock and the specific ground conditions.
The homes in Port Moody vary in age, and so does the drain tile. A camera inspection tells us whether the existing system is modern PVC in good condition or older material that needs replacing.
On a sloped Port Moody property, the replacement also needs to account for the higher water volume moving downhill — the new drain tile and any intercept drains above the house work together to manage that flow.
We plan the replacement around your property, your access, and your schedule, and we show you the camera footage of the old system before any work starts.

How a drainage system protects your Port Moody home
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.

Drain Tile Replacement FAQs in Port Moody
How long does a drain tile replacement take in Port Moody?
A typical residential replacement takes three to five working days depending on access, the size of the footprint, and whether a sump pit and pump need to be installed. We give you a realistic timeline before we start and keep you updated as we go.
Do I need to move out during the work?
No. The work is outside the foundation. It is noisy during excavation, and there will be a trench around the house, but the interior stays liveable. We stage the work so you can get in and out of the house safely throughout.
Will a new drain tile stop my Port Moody basement from leaking?
In most cases, yes — if the drain tile is the source of the water. We inspect first to confirm. If water is also entering through wall cracks or a failed damp-proofing membrane, those need to be addressed as well, and we will tell you that during the inspection.
