Pipe relining has become a popular repair method precisely because it avoids digging up driveways, gardens, and floors, but that popularity has also brought a wide range of operators offering Pipe Relining Melbourne homeowners into the space, not all of whom bring the same level of licensing, materials, or genuine relining experience to the job. Before signing any relining quote, it is worth knowing exactly what separates a properly qualified provider from one simply offering the service without the training or accreditation to back it up. Here are ten questions worth asking before you commit.
1. Does Any Plumber Know How to Reline Pipes?
No, and this is the most important misconception to clear up first. Pipe relining is a specialised technique requiring specific training, equipment, and experience beyond standard plumbing or drain clearing work. A general plumber without dedicated relining training and equipment is simply not equipped to carry out this specific job properly, even if they are fully licensed for other plumbing work. Always confirm the company has genuine, demonstrable relining experience rather than assuming any licensed plumber can offer it competently.
2. What Licence Should the Contractor Hold?
The contractor should hold a current plumbing licence valid in Victoria, and ideally should be able to demonstrate specific training or accreditation in trenchless pipe relining techniques, since this sits outside standard plumbing licensing as a specialised skill set. It is reasonable to ask directly about their relining-specific training and experience, rather than assuming a general plumbing licence alone covers this competency.
3. Should They Provide CCTV Footage Before Quoting?
Yes, this should be standard practice rather than an optional extra. A proper relining quote should be based on an actual CCTV inspection of your pipe, confirming its exact condition, length, diameter, and the location of any junctions, rather than a rough estimate based on a verbal description of the problem. If a company is prepared to quote a relining job without first inspecting the pipe internally, this is a significant warning sign that the resulting quote may not accurately reflect what your specific job actually requires.
4. Should a Quote Specify Pipe Diameter and Length?
Yes. A properly scoped quote should clearly state the exact diameter and length of pipe to be relined, based on the CCTV inspection findings, rather than a vague estimate or a generic per-metre rate applied without confirming the actual measurements involved. This level of detail is what allows you to meaningfully compare one quote against another, and its absence makes it very difficult to know whether you are being quoted fairly for the actual scope of your job.
5. What Liner or Resin Should Be Used?
A reputable relining company should be able to name the specific liner and resin system they use, rather than referring to it only generically as “the lining material.” Established, well-regarded systems in the Australian market are backed by manufacturers who provide clear product specifications and warranty terms, and a company confident in their materials will have no hesitation telling you exactly what system they are installing in your pipe.
6. Should WaterMark Certification Be Checked?
Yes, and this is a non-negotiable point rather than a nice-to-have. Since November 2018, it has been a legal requirement in Australia for pipe relining products to hold WaterMark certification, installed in accordance with the relevant Australian plumbing standards. A company using uncertified relining materials is not compliant with this legal requirement, and products without WaterMark certification are not authorised for legal installation by a licensed plumber. It is entirely reasonable to ask a provider to confirm the WaterMark certification status of the specific liner and resin system they intend to use on your property.
7. Should the Quote Include Pre-Cleaning?
Yes, high-pressure cleaning to properly prepare the pipe before the liner is installed is an essential step, not an optional add-on, since any remaining debris, grease, scale, or root material left in the pipe will compromise how well the liner adheres to the pipe wall. A quote should clearly state whether this preparation work is included in the price or will be charged as a separate item, so you know the full scope and cost before work begins.
8. Should Junction Reinstatement Be Included?
Yes, if your pipe run has junctions where branch lines connect in, as most do. Reinstating these junctions after the liner cures is a necessary and skill-dependent part of a complete relining job, and a quote should clearly state how many junctions are included and confirm this work forms part of the overall price rather than being left as an unstated assumption that could turn into a surprise additional cost later.
9. Is Post-Installation CCTV Mandatory or Best Practice?
It should be considered essential best practice, even if not universally mandatory. A follow-up CCTV inspection after the liner has cured and junctions have been reinstated confirms the job was completed correctly, the liner is properly positioned and adhered, and all junctions are clear and functioning as expected. This footage also becomes valuable documentation for your records and for any future warranty claim, and a reputable company should offer this as a standard part of their process rather than something you need to specifically request.
10. What Warranty Should Be Supplied?
A proper relining warranty should clearly separate the product or material warranty, typically backed by the liner manufacturer, from the workmanship warranty, backed by the installing company itself. Both should be stated in writing with specific timeframes, rather than a single vague figure like “50 years” without clarifying which part of the work that number actually applies to. A significant mismatch, such as a very long product warranty paired with a very short workmanship warranty, is worth questioning directly before proceeding.
What Insurance Should the Contractor Carry?
Beyond licensing, a reputable relining contractor should carry appropriate public liability insurance covering the work being carried out on your property. This protects you in the event of accidental property damage occurring during the job, and it is reasonable to ask for confirmation of current insurance coverage before work begins, particularly for a job involving specialised equipment and processes like relining.
What Are Warning Signs in a Relining Quote?
A few red flags are worth watching for when comparing relining quotes:
- A quote provided without any CCTV inspection of the actual pipe
- Vague descriptions of “the lining material” without naming the specific product or system used
- No mention of WaterMark certification when asked directly
- A warranty figure quoted as a single number without clarifying product versus workmanship coverage
- Junction reinstatement or pre-cleaning not clearly included or itemised
- Reluctance to provide written documentation of the scope, materials, and warranty terms
- A price significantly lower than other quotes with no clear explanation for the difference, such as excluded preparation work or a lesser-known, uncertified liner system
Should Homeowners Obtain Several Quotes?
Yes, particularly for anything beyond a very minor, short-length job. Comparing two or three quotes gives you a genuine sense of the market rate for your specific job, and more importantly, it gives you the opportunity to compare the actual scope of work each company is proposing, since, as outlined above, two quotes that look similar in price can cover very different amounts of preparation, materials, and included work.
What Should Be in Writing Before Work Begins?
Before any relining work starts, you should have written confirmation of the CCTV inspection findings, the exact pipe length and diameter being relined, the specific liner and resin system to be used and its WaterMark certification status, whether pre-cleaning and junction reinstatement are included, the product and workmanship warranty terms stated separately, and whether post-installation CCTV footage will be provided. A company confident in the quality of their work will have no issue providing all of this clearly and in writing before you sign anything.
