Blocked Drains Alexandra Hills

Why drains block in Alexandra Hills

The biggest factor in Alexandra Hills is age. Original drainage from the 1970s through 90s was often earthenware pipe with joints that were never as tight as modern PVC, and forty-plus years on, those joints are a common entry point for tree roots from the large, established trees found on so many blocks in this suburb. It is a slow build — a small root finds a gap, thickens over years, and eventually chokes the line enough to cause a proper blockage.

Sloping blocks, common through Alexandra Hills, add a second factor: drainage falls at odd or reduced grades on some older properties, meaning waste does not always clear the pipe at the rate it should, so solids and grease settle and build up over time rather than washing straight through. Combine that with galvanised water pipes and original fixtures reaching the end of their working life throughout the same house, and Alexandra Hills is a suburb where a blocked drain is often one symptom of a property's plumbing generally being due for a look, not an isolated one-off event.

How we clear it — and how we make sure it stays clear

We run the CCTV camera through the line first, included at no extra cost, which in a suburb like Alexandra Hills usually tells a fuller story — root intrusion at an old joint, a section of earthenware pipe that has partly collapsed, or simply a grade issue on a sloping block. Knowing which one it is changes what we recommend.

Clearing is generally done with high-pressure jet rodding, which cuts through root mass and clears built-up grease and debris far more thoroughly than a cable snake, and it is safe to use on sound older pipe. Roots are cut back at the point of intrusion, and we will tell you plainly if a section of original pipe is past the point where jetting alone is a long-term fix. We re-run the camera to confirm the line is clear before we finish, and clean up on the way out.

What it costs to unblock a drain in Alexandra Hills

Standard residential blocked drain jobs in Alexandra Hills run $250–$450, with the CCTV camera inspection included in that price at no extra cost. You are told the price before we start work. Where the camera shows a section of original pipe that needs repair or replacement rather than just clearing, we quote that separately, with the footage to explain why.

Emergency blocked drains in Alexandra Hills

Sewage backing up in an older home is not something to leave — old pipework under pressure can fail further if a blockage sits too long. For a genuine emergency in Alexandra Hills we aim to be on site within a couple of hours, day or night. Standard blocked drain calls are handled same day wherever we can. Emergency jobs mostly run $250–$600 depending on the repair involved.
