Per house to flush the perimeter drain: crew, hydro-flush of the loop & debris taken away · Updated July 2026
Flushing a perimeter drain in Delta costs $600 to $1,300 installed, and most homeowners pay around $900 for a standard single-family house. This page prices the cleaning job: hydro-flushing the drain tile that loops around your foundation footing so it carries water away again. That is a several-hundred-dollar visit. Replacing a collapsed weeping tile system is a different job an order of magnitude up, and the gap between the two is the single most useful thing to understand before anyone quotes you.
Flushing a Delta perimeter drain costs $600 to $1,000, at Metro rates sitting between Richmond's and Surrey's. Which part of Delta you live in changes the job more than the price does. Ladner and Tsawwassen are flat and at or near sea level behind the dykes, so drainage there ends at a pump rather than a hillside. North Delta sits up on the slope above the Fraser, where gravity does the work and loops run to daylight. One November storm produces two entirely different failures.

What's in the Price — and What Isn't
In the price
- Locating and opening the existing cleanout risers or access points
- Hydro-flushing the drain tile loop around the footing
- Flushing the downspout leads into the system where they tie in
- Vacuuming or collecting the silt and debris that comes back, and hauling it away
- A read on whether the tile is intact, silted, or gone
Costs extra
- A recorded camera inspection, where the contractor prices it separately
- Excavating a new access point on an older system with none (from $600)
- Any replacement of collapsed or crushed tile — that's the $8,000-and-up job
- Regrading, sump work, or downspout re-routing
- Restoring lawn or beds where an access point had to be dug
The number worth having in writing is what happens if the flush fails. A crew that finds crushed tile forty feet in has done work you'll be billed for and delivered a drain that still doesn't run. Ask up front whether a failed flush converts into a credit against replacement, and get the camera footage either way.

What Moves the Price
- Cleaning or replacing
- The fork in the road. A Vancouver-area company puts flushing at $600 to $1,000 for most houses. Replacing the system runs $150 to $300 per linear foot outside the foundation, or $60 to $110 per foot for an interior system, which is how the same address gets a $900 quote and a $30,000 quote in the same week.
- Access points
- Flushing needs somewhere to put the hose. Newer BC houses have cleanout risers at the corners. Older ones often have none, and a Greater Vancouver operator starts an excavated insertion point at $600, before a drop of water goes down the line.
- What's in the line
- Silt and leaf mulch flush out. Roots, collapsed sections, and crushed tile do not, and no amount of pressure will change that. The camera is what tells you which one you have.
- Perimeter length
- The loop follows the footing, so a house with a wraparound addition and a stepped foundation has considerably more pipe than a rectangular bungalow. Flushing is usually priced per job rather than per foot, but the job price still tracks the footprint.
- Landscaping, if it becomes a replacement
- The biggest swing in the whole category. A Fraser Valley contractor quotes $15,000 to $25,000 for excavation and install on an existing home with no landscaping restoration, and $25,000 to $50,000 for the same house when patios and walkways have to come out and go back.
- When you book
- BC drainage crews are booked solid from the first November atmospheric river through February. The cheapest version of this job is the one scheduled in August, when nobody is standing in a flooded crawlspace.

How the Job Actually Goes
-
Finding the access
The crew locates cleanout risers, usually at the corners, and checks where downspouts and any catch basins tie into the loop. On an older house with no risers, this is where the conversation about digging an insertion point starts.
Included; excavated access from $600
-
Flushing the loop
High-pressure water goes in at each access and works around the footing, lifting silt, leaf mulch, and iron ochre off the tile. On a house with corner risers the crew can work the loop in sections rather than blind.
The bulk of a $600–1,000 flush
-
Recovering the debris
What comes loose gets vacuumed or collected at the low point rather than left to settle somewhere else in the system. This is the step that separates a real flush from a hose down a pipe.
Included, and part of why disposal shows up in the bill
-
Camera inspection
The camera goes around the loop after the flush and records pipe condition. A customer review from a Langley-area drainage company documents $1,250 paid for flushing and camera together, which is the realistic all-in for this service.
$150–400 on top where it's priced separately
-
The verdict
Silted but intact means you've bought several more years. Crushed, root-bound, or missing tile means the footage is now the first page of a replacement quote, and the price bracket changes completely.
Replacement runs $150–300 per foot exterior, $60–110 interior
Do It Yourself or Hire a Pro?
Doing it yourself
- Downspouts, leaf traps, and catch basin grates are yours to keep clear, and most silt in a perimeter drain arrived through one of them
- Cleaning gutters twice a year through a coastal BC autumn does more for the system than any single service call
- A garden hose down a cleanout riser moves nothing. The service uses flow and vacuum recovery you cannot rent
- There is no way to see what you accomplished without a camera, so a DIY flush leaves you exactly as informed as before
- The debris has to go somewhere. Pushing silt further around the loop toward the sump just relocates the blockage
- Old clay tile and the perforated fibre used through the 1960s and 1970s break under pressure, and pressure applied blind is how it happens
Hiring a licensed pro
- Enough flow to carry silt out rather than move it along, with the debris recovered instead of redistributed
- A camera that answers the only question that matters: is this drain dirty or is it dead
- Footage that stands up in a pre-sale negotiation, which in coastal BC is often why the job was booked
- Someone who has seen a hundred of these can tell a silted 1978 system from a collapsed one in about a minute
- $600 to $1,250 for a service that produces no visible change above ground
- If the tile is gone, you've paid for a diagnosis rather than a repair — although it's a diagnosis you needed
Our take: Flushing is worth booking on any coastal BC house whose perimeter drain hasn't been touched in a decade, and it is worth booking in the dry months rather than in the middle of a November storm. What it cannot do is rescue a system that has already collapsed. If the camera shows crushed or root-filled tile, stop paying for cleaning and start pricing replacement.
Signs It's Time to Replace
- Water pooling against the foundation after rain instead of draining away within a few hours
- A damp crawlspace, efflorescence on basement walls, or that particular smell coastal BC basements get in December
- Downspouts backing up and overflowing at the elbow where they enter the ground
- The house was built before the mid-1980s and nobody has ever flushed the system
- You're listing the house, and a BC buyer's inspection will ask about the perimeter drains
- Honest catch: recurring water in the basement after a flush usually means the tile is gone, not dirty. Flushing it again is the most common wasted $800 in this category
How to Keep the Cost Down
- Book it in summer. Every drainage crew in the Lower Mainland is committed from the first November storm onward, and shoulder-season scheduling is where the flexibility on price lives
- Get the camera footage in your hands. It's the difference between a replacement quote you can challenge and one you have to take on faith
- Flush before you list, not after the buyer's inspector does. A $900 service on your schedule beats a price reduction negotiated against a $25,000 replacement quote
- Fix the input first. Clean gutters, working leaf traps, and downspouts that discharge away from the wall keep silt out of a system you just paid to clean
- If it does turn into a replacement, take the landscaping restoration out of the drainage contractor's scope. That element alone moves a Fraser Valley project from $15,000–25,000 to $25,000–50,000, and a landscaper prices it far better
Delta Notes: Permits, Homes, Rates
Gas permits go through Technical Safety BC ($116 on a contractor permit, 2026); the City of Delta issues plumbing permits for its three communities.
Ladner's older streets have fine delta silt packed against the tile, and fine sediment is exactly what settles inside a perforated line and stays there. Most sea-level Delta houses have no basement, so a plugged loop reads as a soggy crawlspace and a lawn that never dries rather than a flooded rec room. North Delta's 1970s and 1980s split-levels are the clay-tile stock, on a slope that at least keeps water moving through them.
Metro Vancouver rates, a little above the BC average and roughly between Richmond and Surrey.
Questions to Ask Before You Hire
- Is the price a flat rate for the house, or does it change once you see the perimeter?
- Is a camera inspection included, and does the footage come to me afterward?
- What do you do if there's no cleanout riser, and what does creating one cost?
- If the flush doesn't restore flow, what am I charged and does any of it credit toward replacement?
- Are you flushing the downspout leads and catch basins as well as the footing loop?
- Have you got a per-foot replacement rate, so I can price the worst case today?
While the Plumber Is There
Call-out time is a big share of any bill — if one of these applies to your home, pricing it in the same visit usually beats a separate appointment.
On a flat or low-lying BC lot the perimeter drain discharges into a sump, and a clean drain feeding a dead pump gets you nowhere. Have both looked at in the same visit.
It's the same truck and the same crew. If the sewer lateral is due for a jetting anyway, doing both while the equipment is on your driveway is the cheapest scheduling you'll get.
If your perimeter drains do turn out to need replacing, an excavator is coming anyway. Knowing the condition of the sewer lateral first can turn two separate digs into one.
