- Google reviews do the ranking. We start with every plumber’s live Google star rating and the number of reviews behind it, pulled fresh from Google Maps.
- Rating, weighted by volume. A 5.0 from a handful of jobs isn’t proof yet, so we weight the score by review count. A proven 5.0 from dozens of jobs isn’t beaten by a 5.0 from a handful.
- Licence matters. Every business here trades as a licensed plumbing/gas operator. We still tell you how to check the licence number yourself before you hire, see the checklist.
- Paid spots are labelled, and never jump the queue. When a business pays for a “Featured” spot it’s marked as such. The review-based order below does not change to favour a payer. Right now, no spots are sold.

What plumbing actually costs in Northam (2026)
Nobody likes ringing a plumber blind on price. These are honest Avon Valley ballpark ranges for the common jobs, GST included. They’re a guide to keep you from being overcharged, not a quote. Being an hour or two from Perth, regional call-outs out here can run a touch higher once travel to the rural blocks is factored in, so always get the job priced in writing before work starts.
| Job | Typical Northam range | What pushes it up |
|---|---|---|
| Standard call-out + first hour | $100-$220 | Travel to rural blocks, after-hours, weekends |
| Leaking / dripping tap (re-washer) | $90-$220 | Seized fittings, mixer replacement |
| Blocked drain, basic (plunger/snake) | $150-$400 | Tree roots, needing a jetter or camera |
| Blocked drain, jetter + CCTV camera | $400-$850+ | Collapsed or root-filled pipe, excavation |
| Toilet repair (cistern / flush valve) | $120-$320 | Full pan replacement, concealed cistern |
| Burst pipe repair | $150-$550 | Access (walls/slab), length of pipe run |
| Hot water, electric storage (supply + install) | $1,200-$2,600 | Relocation, tempering valve, tight access |
| Hot water, gas storage / continuous flow | $1,300-$2,900 | New gas line, flue work, unit size |
| Hot water, heat pump (before rebates) | $2,500-$4,500 | Electrical work; rebates can cut this a lot |
| Rainwater tank / pump work | $300-$1,500 | Common on rural and coastal blocks; pump size and plumbing runs |
After-hours and emergency call-outs usually carry a 50-100% loading, and travel out to rural and farm blocks adds time. Many Avon Valley properties run rainwater tanks and pumps, and the hard Wheatbelt water is tough on hot water systems, so it pays to service them. A licensed plumber should give you a fixed price or a not-to-exceed figure before starting. If they can’t, that’s a red flag (see below).
Don’t get ripped off: red flags
- No licence number, anywhere. In WA, plumbing and gas work must be done by a licensed plumber. If they won’t give you a licence number on the quote or invoice, walk away, no exceptions.
- Cash only, no receipt, no written quote. No paper trail means no warranty and no comeback if it fails. You’re carrying all the risk.
- Open-ended hourly with no cap. “We’ll see how we go” is how a $200 job becomes $700. Get a written quote or a not-to-exceed price before they lift a tool.
- Selling a full replacement for a simple fix. “Your whole hot water system needs replacing” when it might be a $200 valve. On any big-ticket call, get a second quote.
- Vague on warranty, or “today-only” pressure. Good plumbers stand behind their labour in writing and don’t rush you into deciding on the spot. Pressure is a sales tactic, not a plumbing one.
Before you hire: quick checklist
- Licence. Confirm the plumber’s PL number and check it on the WA licensed plumber register (Building & Energy, DEMIRS). Gas work needs a gas fitting authorisation too.
- Insurance. Ask for current public liability cover, it protects your home if something goes wrong.
- Written quote. Itemised and in writing, before work starts. Verbal prices have a way of growing.
- Warranty. Get the labour warranty in writing, and make sure manufacturer warranties on parts (like hot water units) are passed to you.
- Recent reviews. Look for recent, specific reviews, not just a big number. A steady stream of detailed 5-star jobs beats one old burst of them.
Frequently asked
How did you rank these plumbers?
By their live Google star rating and the number of reviews behind it, pulled from Google Maps. We weight the rating by review volume so a proven high score from many customers isn’t leapfrogged by a 5.0 from a handful. Every plumber here trades as a licensed plumbing/gas business.
Are these paid placements?
No. This list is ordered on Google review data. Businesses can pay for a “Featured” spot at the top, which is clearly labelled, but paying never changes the review-based order below. As of this update, no spots are sold.
Do I really need a licensed plumber for small jobs?
In WA, yes, almost all plumbing and gas work must legally be done by a licensed plumber or gas fitter, even minor jobs. Using an unlicensed operator can void your home insurance and leave you liable if the work fails. It’s not worth the saving.
How often is this page updated?
Monthly. Ratings and review counts move, new plumbers earn their spot, and we re-pull the data so the list stays honest and current.
