Drain & Blocked Drains in Perth metro
A blocked drain in Perth usually means one of a few things: tree roots working into old clay pipe joints, a build-up of fat and grease in kitchen lines, foreign objects lodged in toilet or laundry drains, or sagging and cracked pipe sections that trap waste over time. Fixing it can range from a simple hand-auger clear of a sink trap to a full CCTV drain inspection followed by high-pressure jet cleaning or, in worse cases, pipe relining or excavation to replace a collapsed section. With 413 businesses offering this work across the metro area, the range in equipment, pricing and honesty about what's actually needed is wide.
Before booking, ask whether the plumber uses a drain camera to actually diagnose the blockage rather than guessing, and whether they'll show you the footage. Ask if the quote is fixed or hourly, and what happens if the job turns out to be bigger than expected (a root intrusion, for example, often needs relining rather than just a jet clean). Check they're licensed and insured for drainage work specifically, since this sits alongside but is distinct from general plumbing.

Common questions about drain & blocked drains
- How much does it cost to clear a blocked drain in Perth?
- A straightforward clear with an electric eel or hand auger for a single fixture, like a sink or shower, often falls in the $150-$300 range depending on access and time of day. A full CCTV inspection plus high-pressure jetting for a main line blockage typically costs more, often $300-$600, and can climb higher if tree roots or a collapsed pipe are found and relining or digging is needed. After-hours or emergency callouts usually carry a premium on top of the standard rate.
- How often should drains be checked or cleaned to avoid blockages?
- If you've got established trees near old clay or earthenware pipes, an annual root-clearing jet clean can prevent an emergency callout. Kitchens with heavy grease use benefit from having drains professionally cleared every 12-18 months. Newer PVC systems in good condition generally need far less frequent attention, often only when a blockage actually occurs.
- What should I expect during a blocked drain callout?
- A competent plumber will first ask what's blocked and where, then use a camera to locate the actual problem before recommending a fix. Expect them to try the least invasive method first (jetting or an eel) before suggesting relining or excavation, and to explain costs before starting extra work rather than after.
- How can I tell if a drain plumber has done a good job?
- Water should drain freely with no gurgling or slow pooling for weeks afterward, not just immediately after the visit. A good operator will also tell you what caused the blockage and whether it's likely to recur, rather than just clearing it and leaving.
