Is It the Sewer or One Slow Drain?

One slow basin is a drain. A pattern across the whole house is the sewer, and the signs stack up:

Gurgling from the toilet when other taps run
Several fixtures backing up at once, especially the lowest ones
Sewage coming up through the lowest floor wastes or yard grates
A wet, smelly patch in the yard along the line's route

Any of those means stop using the water and ring us. Every flush adds to what the line has to push through.

Why Sewers Choke on These Older Blocks

The pipe material is the starting point

Lambton's Federation homes and mining-era cottages drain through earthenware and clay sewers, and after a century that clay has gone brittle, with the joints loosening where the ground works at them.

Roots and soil finish the job

Mature gardens and street trees push roots into an open joint, where they thread through and catch everything flowing past. The reactive clay here takes up water in a wet spell and pulls back in a dry one, shifting on the shale beneath and prising at the joints year after year. A sewer off Dickinson Street or Young Road is fighting age, roots and ground movement all at once.

Clearing is step one, not the whole job

The blockage comes out, then the camera goes through to check the pipe wall for cracks. That footage settles the choice between another clear and a reline or new section, and you watch it before anything more is quoted.

How the Clearing Runs

01
Confirm the fault
We check the fixtures and access points to establish that the sewer is the problem, not a single branch drain.
02
Clear the choke
The electric eel or high-pressure jetter cuts the blockage out, matched to the pipe's condition.
03
Camera the line
Vision from before and after the clean shows where the fault sat and how the pipe wall looks now.
04
Fix the cause
Where a joint has split or dropped, you get a price for relining or a new section while the vision is still up.

If the line is past clearing, pipe relining can renew it without digging, and CCTV drain inspection explains the camera work in detail. Rain-fed overflows are a separate job under stormwater drains, and every other drain job sits under blocked drains.

What Drives a Sewer Repair Quote?

We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.

It costs nothing to get us out to your door (excluding after-hours).

The figure depends on:

Access A line reachable through an inspection opening costs less to work on than one under paving or a slab.
Pipe material and condition Brittle earthenware needs a gentler hand than newer PVC, and a cracked line means more than a clearing.
How far the fault sits in Depth and distance change the equipment and the time on site.
Clear or repair Clearing alone costs less than relining or digging out a section, and the camera vision tells you which of those the line needs.

When we're not the right call. If the camera shows the choke sitting past your connection point in the public main, that length is the water authority's to clear, and we stop there rather than bill you for it.

Where Sewers Fail First

The housing stock sets the failure rate. Census figures put Lambton at 2,078 dwellings, and 76.1 per cent are separate houses, a good share of them pre-1940 cottages. The cottages around the Lambton Bowling Club's greens and the Federation homes near Lambton High School on Young Road were sewered in clay a century ago, and those are the lines that surcharge without warning. Roots from the established gardens push into any joint that opens, and a sewer that keeps blocking usually hides a cracked or dropped pipe under the choke.

Sewer Questions From Local Households

Why does my sewer block more often than my neighbours'?

Much of the older housing here was sewered in earthenware and clay, and those joints loosen as the pipes age. Roots and silt catch at every cracked joint, so an old line can block repeatedly until it is relined or replaced.

Can a blocked sewer wait until the weekend?

No. Once waste stops draining it looks for the lowest exit, usually a floor waste or yard grate. A surcharging sewer is treated as urgent, and we are Available 24/7.

Do you check the sewer is clear before you leave?

Yes. We run the camera through the line after clearing to confirm the blockage is gone and to show you the condition of the pipe wall, so you know whether the fix will hold.

Who fixes the sewer main in the street?

The water authority owns the public main in the street. We clear and repair your private line up to the connection point; a choke beyond it goes to the authority's faults line.
