Starworks ranks 12 drilling & water bore contractors in Kalgoorlie, WA, holding 100 Google reviews between them. Across the 12 the median rating is 4.4 stars from a median of 5 reviews. Of the 12, 4 are rated 4.5 or better. The most-reviewed carries 31 reviews, more than the top-ranked drilling contractor holds, which is why rating alone does not set the order.
What star rating should I expect from a good drilling contractor in Kalgoorlie?
The median Google rating across the 12 drilling & water bore contractors Starworks ranks in Kalgoorlie, WA is 4.4 stars, and 4 of them sit at 4.5 or above. A rating at or near that median is ordinary for drilling & water bore contractors in Kalgoorlie, 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 drilling contractor in Kalgoorlie have?
The median drilling contractor Starworks ranks in Kalgoorlie, WA carries 5 Google reviews. The most-reviewed of them carries 31.
How does Starworks rank drilling & water bore contractors in Kalgoorlie?
Starworks gives every drilling contractor in Kalgoorlie, 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 drilling contractor in Kalgoorlie 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 drilling contractor with a handful of excellent reviews may still be the right choice in Kalgoorlie, WA. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same drilling contractor 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 12 distinct drilling & water bore contractors in Kalgoorlie, WA rather than a longer list of repeats.
How often is this list of drilling & water bore contractors in Kalgoorlie updated?
This ranking of drilling & water bore contractors in Kalgoorlie, 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 drilling contractor business ranking in Kalgoorlie?
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 drilling contractor Starworks ranks in Kalgoorlie, WA carries 5 Google reviews at 4.4 stars.
