Balmain's drains are among the oldest in Sydney, running under workers' cottages and terraces on sandstone and down steep streets toward the harbour. Help Plumbing clears blocked drains Balmain homes and businesses deal with, from our base in Earlwood, typically 15 to 20 minutes away. We look with a camera before quoting and clear the line with a jetter. Call (02) 9538 7878.
Why blocked drains Balmain cottages get keep coming back
Old earthenware and cast iron drains under Balmain cottages have open joints, and roots from gardens and street trees grow straight into them. The jetter clears them, but a cracked joint lets them back in within a year or two. Many blocked drains Balmain owners report are the same blockage returning, which is the sign the pipe itself needs attention.
Sandstone and relining
Balmain sits on sandstone, so many drains are laid in rock or shallow soil over rock. Digging up a broken line means cutting stone, which is slow and expensive. Relining repairs the pipe from the inside instead, through an existing access point, and it's done by our partner relining team the day after we quote it. For blocked drains, Balmain's rock makes relining worth pricing before any dig.
Boundary traps
Many older Balmain homes have a boundary trap near the front fence: a bend in the drain that stops sewer gas coming back from the main. It's a common place for a blockage, and when it blocks, the gully in the yard overflows first. A blocked boundary trap is behind plenty of the blocked drains Balmain homes report, and we camera the line past it once it's clear.
Steep streets and stormwater
Water moves fast down Balmain's steep streets. Homes on the low side collect stormwater from above, and courtyard pits and old stormwater lines block with leaves and silt. When they do, water pools against the house. Clearing those pits and lines is a regular part of the blocked drains Balmain homes get after heavy rain.
Darling Street pubs and restaurants
Darling Street's pubs, cafés and restaurants put a lot of grease into their drains. A grease trap that's overdue for a service pushes grease into the line and blocks it during a busy night. In a commercial kitchen, grease is the usual cause of the blocked drains Balmain restaurants report. We service grease traps and clear blocked kitchen lines outside trading hours where we can. See our commercial plumbing service.
How we clear blocked drains Balmain homes report
We follow the same steps for all blocked drains Balmain homes report. The camera goes in first, through a gully, an inspection opening or a boundary trap, so we know what we're dealing with. Roots, grease and silt come out with the jetter, and a mechanical auger handles what the jetter can't. A final camera run proves the line is clear, and you get a written summary of the cause. More on the process is on our blocked drains page.
Before a renovation
If you're renovating a Balmain cottage, have the old drains checked before the new bathroom goes in. A camera inspection shows whether the line can take the new work or needs relining while the house is open. Finding a cracked pipe now is easier than dealing with blocked drains Balmain renovations run into later. See our CCTV camera inspections service.

Blocked drains Balmain FAQs
How quickly can you get to Balmain?
Typically 15 to 20 minutes from Earlwood, so blocked drains Balmain homes report in the morning are often cleared the same day. Sewer overflows go to our 24/7 line.
The same drain blocks every year. Why?
Usually roots getting into a cracked joint, which is behind many repeat blocked drains Balmain homes get. Relining is the long-term fix, and the camera shows whether it suits your pipe.
Do you need to dig through the rock?
Usually not. Relining repairs the pipe from inside. Digging is a last resort on sandstone.
Can you clear a pub's kitchen drain after hours?
Yes. We schedule commercial work early, late or overnight where we can.
Is there a trap near our front fence?
In many older homes, yes. If your yard gully overflows, the boundary trap is one of the first places we check when clearing blocked drains Balmain homes report.
What does it cost?
It depends on what the camera finds. You get a fixed price for clearing blocked drains Balmain homes and businesses need before anything starts.
