Placement on this list cannot be bought.

Question 2

How many waterproofing contractors does Starworks rank in Rockingham?

Accepted Answer

Starworks ranks 10 waterproofing contractors in Rockingham, WA, holding 729 Google reviews between them. Across the 10 the median rating is 5.0 stars from a median of 8 reviews. Of the 10, 8 are rated 4.5 or better and 1 has passed 100 reviews.

Question 3

What star rating should I expect from a good waterproofing contractor in Rockingham?

Accepted Answer

The median Google rating across the 10 waterproofing contractors Starworks ranks in Rockingham, WA is 5.0 stars, and 8 of them sit at 4.5 or above. A rating at or near that median is ordinary for waterproofing contractors in Rockingham, WA rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.

Question 4

How many Google reviews does an established waterproofing contractor in Rockingham have?

Accepted Answer

The median waterproofing contractor Starworks ranks in Rockingham, WA carries 8 Google reviews, and 1 of the 10 waterproofing contractors have passed 100.

Question 5

How does Starworks rank waterproofing contractors in Rockingham?

Accepted Answer

Starworks gives every waterproofing contractor in Rockingham, 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.

Question 6

Why does a waterproofing contractor in Rockingham with all 5-star reviews score lower than one with a lower rating?

Accepted Answer

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 waterproofing contractor with a handful of excellent reviews may still be the right choice in Rockingham, WA. The star rating and review count sit next to every score so you can weigh both yourself.

Question 7

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

Accepted Answer

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 10 distinct waterproofing contractors in Rockingham, WA rather than a longer list of repeats.

Question 8

How often is this list of waterproofing contractors in Rockingham updated?

Accepted Answer

This ranking of waterproofing contractors in Rockingham, 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.

Question 9

How can I improve my waterproofing contractor business ranking in Rockingham?

Accepted Answer

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 waterproofing contractor Starworks ranks in Rockingham, WA carries 8 Google reviews at 5.0 stars.
