The main water line runs underground from the city connection to your house.

You don't think about it until something's wrong.

A water bill that jumped for no reason.

Nothing changed, but usage went up. That water is going somewhere.

A wet or unusually green patch in the yard.

Especially if it stays wet in dry weather, or the grass over one strip is greener than everything around it.

Pressure dropping across the whole house.

Not one tap all of them.

Water pooling in the driveway or at the curb.

The sound of running water when nothing's on.

Discoloured water, if the line is old and corroding.

Any of these, get it looked at. A leaking service line wastes water every hour and can undermine a driveway or foundation if it's left.

Signs your main water line is failing

Who's responsible for the water line? (You might be.)

This is the part most homeowners get wrong, and it's an expensive thing to be wrong about.

The municipality owns the water main in the road, and typically the portion of the service line up to the property line or the curb stop.

You own the rest — the section running from there, under your yard and driveway, into your house.

So if the leak is on your side, it's your bill. Not the city's.

If you're not sure which side the problem is on, we'll find out before anyone starts digging.

Responsibility can vary between the Township of Langley and the City of Langley. Worth confirming with your municipality — and worth knowing before you assume the city is going to handle it.

What trenchless actually means

The traditional method is an open trench. A machine digs a channel from the street to your house, straight through whatever's in the way — lawn, garden, driveway, walkway. The pipe goes in. Then the trench gets filled, and you're left restoring everything on top of it.

Often the restoration costs more than the plumbing.

Trenchless replaces the same pipe through two small access pits — one at each end. No open trench between them.

Pipe bursting is the usual method: a bursting head is pulled through the old pipe, fracturing it outward into the surrounding soil while pulling the new line in behind it. The new pipe takes the old pipe's path. Your lawn stays a lawn.

What we install: HDPE or PEX service line. No corrosion, no joints in the buried run, and it will outlast the house.

Trenchless vs. open trench

Trenchless is usually the better call when:

The line runs under a driveway, patio, walkway, or mature landscaping
There are trees you'd rather not lose
You want the job done in a day rather than a week
Restoration cost would exceed the plumbing cost

Open trench can still make sense when:

The line is very shallow and the run is short
The route is clear — bare lawn, nothing in the way
The old pipe is collapsed or misaligned badly enough that bursting won't track it

We'll tell you honestly which one your property needs. Trenchless isn't right for every job, and we won't sell it to you if it isn't.

What it costs

The two things that drive the price: how long the run is, and what's on top of it.

The part people miss: open-trench quotes usually don't include putting your property back together. A cheaper trench quote plus new sod, new landscaping, and a re-poured driveway section often lands above the trenchless number.

Compare the total, not the plumbing line item.

Questions we get

How long does it take?

Most residential trenchless replacements are done in a day. An open trench on the same property can take several days, plus however long the restoration takes.

Will you dig up my driveway?

No that's the point of trenchless. We need an access pit at each end. The run between them is untouched.

Is trenchless more expensive?

The plumbing itself can cost more. The total is often less, once you're not paying to replace a driveway and a lawn. Get both numbers before you decide.

How do I know if the leak is on my side or the city's?

We'll locate it. Generally the municipality is responsible up to the property line and you're responsible from there to the house — but confirm with your municipality, and don't assume.
