As of October 2026, the 3 highest-ranked plumbers in Northam, WA on the Starworks directory are Perth Plumbing Services - Freshwater Pty Ltd (4.8 stars from 79 Google reviews), Beta Plumbing & Gas (5.0 stars from 11 Google reviews) and BlockAid Plumbing and Gas (5.0 stars from 4 Google reviews). Every figure here is computed from Google review data that Starworks collects for plumbers in Northam, WA, recalculated when this page rebuilds. Placement on this list cannot be bought.

How many plumbers does Starworks rank in Northam?

Starworks ranks 11 plumbers in Northam, WA, holding 169 Google reviews between them. Across the 11 the median rating is 5.0 stars from a median of 4 reviews. Of the 11, all are rated 4.5 or better.

What star rating should I expect from a good plumber in Northam?

The median Google rating across the 11 plumbers Starworks ranks in Northam, WA is 5.0 stars, and all of them sit at 4.5 or above. A rating at or near that median is ordinary for plumbers in Northam, WA rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.

How many Google reviews does an established plumber in Northam have?

The median plumber Starworks ranks in Northam, WA carries 4 Google reviews.

How does Starworks rank plumbers in Northam?

Starworks gives every plumber in Northam, WA a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.

Why does a plumber in Northam with all 5-star reviews score lower than one with a lower rating?

Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer plumber with a handful of excellent reviews may still be the right choice in Northam, WA. The star rating and review count sit next to every score so you can weigh both yourself.

Why does the same plumber not appear several times on this list?

Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 11 distinct plumbers in Northam, WA rather than a longer list of repeats.

How often is this list of plumbers in Northam updated?

This ranking of plumbers in Northam, WA rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.

How can I improve my plumber business ranking in Northam?

Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median plumber Starworks ranks in Northam, WA carries 4 Google reviews at 5.0 stars.
