Hiring a Drainer in Cranebrook
Before hiring any drainer in Cranebrook, use this checklist to protect yourself and ensure you're working with a properly licensed and insured professional.
- Confirm they hold a specific drainage licence, not just a plumbing licence — In Queensland, NSW, and several other states, drainage work requires a separate Drainer licence. A plumber licensed only for water supply and sanitary plumbing may not be authorised to perform drainage work. Check the licence class on your state regulator's website. In some states (e.g. Victoria), plumbing registration covers drainage, but in others, it does not.
- Ask for a CCTV inspection before committing to major drainage repairs — A CCTV pipe inspection (using a camera inserted into the drain) provides video evidence of the exact location and nature of the problem — tree root intrusion, cracked pipes, joint displacement, or bellied sections. A drainer who recommends excavating and replacing pipes without first performing a CCTV inspection may be recommending more work than is needed. CCTV inspections typically cost $200–$500.
- Check whether they can provide pipe relining as an alternative to excavation — Pipe relining installs a resin-impregnated liner inside the existing pipe, creating a new pipe within the old one — without excavation. This method is faster, less disruptive, and often cheaper than traditional dig-and-replace for damaged sewer and stormwater pipes. Not all drainers offer relining. If your drainage problem can be solved with relining, ask whether the drainer is trained and equipped for it.
- Ask about council requirements for stormwater detention or OSD — Many Australian councils require new buildings and significant renovations to install an On-Site Stormwater Detention (OSD) system to limit stormwater runoff. The drainer should be familiar with your council's OSD requirements, including permitted discharge rates and detention tank sizing. Non-compliant stormwater systems can result in failed council inspections and costly rectification.
- Get clarity on the depth and location of existing services before excavation — Drainage excavation often occurs near other buried services — water mains, gas lines, electrical cables, and telecommunications. A competent drainer will request a Dial Before You Dig (DBYD) report and use a service locator before excavating. Hitting a gas main or electrical cable during drainage excavation is dangerous and expensive.
Get at least three quotes and compare not just price, but response time, warranty on workmanship, and whether the quote includes parts.
- Recommends excavation without a CCTV inspection first — A drainer who jumps straight to "we need to dig up your yard" without first inspecting the pipe with a CCTV camera may be recommending unnecessary work. CCTV inspection is a standard diagnostic tool that costs $200–$500 and can save thousands by identifying the exact problem location and whether relining is a viable alternative to excavation.
- Does not hold a specific drainage licence — In states where drainage is a separate licence class (e.g. Queensland, NSW), performing drainage work without the correct licence is illegal. Unlicensed drainage work may not be covered by home warranty insurance and may not be accepted by council or your water authority for compliance certificates.
- Does not call Dial Before You Dig before excavating — Dial Before You Dig (DBYD) provides information on the location of underground services (gas, electricity, water, telecommunications). Excavating without a DBYD report is reckless and can result in hitting a gas main, electrical cable, or water main — causing service outages, property damage, and potentially fatal injuries. A competent drainer always orders a DBYD report before any excavation.

Frequently Asked Questions
How much does it cost to fix a blocked drain in Australia?
A simple drain unblock using an electric eel or high-pressure water jetter typically costs $150–$400. If the blockage is caused by tree roots or a collapsed pipe, further investigation (CCTV inspection: $200–$500) and repair may be needed. Pipe relining for a damaged section costs $500–$1,500 per metre. Full excavation and pipe replacement costs $200–$500 per metre plus reinstatement of landscaping, driveways, or concrete. A typical sewer line repair (5–10 metres) costs $2,000–$8,000.
What is the difference between a plumber and a drainer?
A plumber installs and maintains the water supply, hot water, and internal sanitary plumbing (basins, toilets, showers) inside a building. A drainer installs and maintains the below-ground drainage systems that carry wastewater from the building to the sewer main and stormwater from the site to the stormwater system. In some states these are separate licence classes; in others, a plumbing registration covers both. For below-ground pipe work, always confirm the tradesperson holds a drainage licence or endorsement.
How do I know if I have a drainage problem?
Common signs include slow-draining fixtures (sinks, showers, toilets), gurgling sounds from drains when other fixtures are used, sewage odours in the yard or house, patches of unusually green or lush grass over the sewer line (indicating a leak feeding the soil), pooling water in the yard after rain, and rising damp or water stains on lower walls. Recurring blockages in the same drain line are a strong indicator of a structural problem (root intrusion, cracked pipe, or belly) that needs investigation.
What is pipe relining and when is it suitable?
Pipe relining is a trenchless repair method where a flexible liner saturated with epoxy resin is inserted into the existing damaged pipe, inflated to press against the pipe walls, and cured in place — creating a new pipe within the old one. It is suitable for cracked, joint-displaced, or root-damaged pipes that are still structurally intact enough to hold the liner. It is not suitable for completely collapsed pipes or pipes with significant changes in diameter. Relined pipes have a life expectancy of 50+ years.
Do I need council approval for drainage work?
New sewer connections and disconnections require approval from your water authority (e.g. Sydney Water, Unity Water, SA Water). New stormwater drainage connections to council infrastructure may require a plumbing/drainage permit or engineering approval, particularly for OSD (On-Site Detention) systems. Internal drainage repairs and maintenance typically do not require approval, but the drainer should still issue a compliance certificate for regulated work.
How do I verify a drainer's licence in NSW?
You can verify any drainer's licence using TradieVerify's free search tool or directly through the NSW Fair Trading register. Enter the drainer's name or licence number to confirm their licence status, class, and any disciplinary history.
