Getting a written quote before any drain cleaning work begins is one of the smartest things you can do as a homeowner. A clear, detailed quote protects you from unexpected costs, helps you compare tradespeople fairly, and gives you a record of exactly what was agreed. Here's what a reputable NZ drain cleaner should include in their written quote.
Tradesperson Details and Licensing
The quote should clearly show the business name, physical address, phone number, and email of the drain cleaning company. In New Zealand, drainlaying work — including clearing blockages that involve entering or modifying drain lines — may be restricted work that must be carried out by a licensed drainlayer registered with the Plumbers, Gasfitters and Drainlayers Board (PGDB). Always check that the tradesperson's licence number is included on the quote, and verify it on the PGDB register before work begins.
A Clear Description of the Work
Vague quotes lead to disputes. The quote should spell out:
- What the problem is (e.g., blocked kitchen drain, slow-draining shower, collapsed stormwater pipe)
- Where the work will be carried out — the specific drain, location on the property, and whether it's inside or outside
- The method to be used — for example, high-pressure water jetting, electric eel (drain snake), CCTV drain inspection, or manual rodding
- Whether a CCTV camera inspection is included or quoted separately — this is often recommended before and after clearing a blockage to confirm the cause and result
Itemised Pricing
A professional quote should break costs down so you can see exactly what you're paying for. Look for:
| Item | What to check |
|---|---|
| Call-out fee | Is it charged separately or included? |
| Labour (per hour or fixed price) | How many hours are estimated? |
| Equipment hire/use | e.g., jetting machine, CCTV camera |
| Materials | e.g., replacement pipe sections, access covers |
| Disposal fees | Removal of debris or waste |
| GST | Must be shown separately — all NZ quotes should state whether prices are GST-inclusive or exclusive |
Broad price ranges vary widely depending on the job complexity, location, and access, so always get at least two or three quotes to compare.
Scope Inclusions and Exclusions
A good quote will clearly state what is not included. For example:
- If tree root removal is found during jetting, is that covered?
- If the drain is found to be cracked or collapsed on CCTV, is repair work a separate quote?
- Are there extra charges for after-hours or weekend callouts?
Having exclusions in writing means there are no nasty surprises if the job turns out to be more complex than expected.
Timeframes
The quote should include an estimated start date and how long the work is expected to take. For urgent blockages, confirm whether the tradesperson offers same-day or emergency service and whether that attracts a premium rate.
Guarantees and Warranties
Reputable drain cleaners will often offer a workmanship guarantee — for example, a guarantee that the drain will flow freely for a set period after jetting. Ask for this in writing. If any replacement materials are used (such as pipe sections or fittings), the quote should note the manufacturer's warranty that applies.
Health, Safety, and Site Conditions
Drain work can involve exposure to wastewater and hazardous gases. A professional tradesperson should note any relevant health and safety considerations in their quote, particularly if work involves confined spaces or older properties where asbestos-containing materials might be present near drain lines. WorkSafe NZ sets the standards for safe work practices in these situations.
Consent and Compliance Notes
Most routine drain clearing does not require a building consent, but repairs or alterations to drain lines may require one under the NZ Building Code. The MBIE Building Performance website has guidance on what triggers consent requirements. Your tradesperson should flag this in the quote if it applies, and you should always confirm with your local council if you're unsure.
Payment Terms
The quote should clearly state:
- Deposit requirements (if any)
- When final payment is due (on completion, within 7 days, etc.)
- Accepted payment methods
Be cautious of any tradesperson who asks for a large upfront payment before any work is done.
When to Call a Professional
If you have a blocked or slow drain, it's tempting to try a chemical drain cleaner from the hardware store first — and for minor blockages, that may be fine. However, call a licensed drainlayer if:
- The blockage keeps returning
- Multiple drains in the house are blocked at once
- You notice sewage smells, gurgling sounds, or water backing up
- You suspect a cracked, collapsed, or root-invaded drain
- The drain is part of a shared or council-connected system
