How it works

How we list and rank

No ads, no paid placements and no lead selling. Here’s exactly how the directory decides what you see.

Who gets listed

Any Washington well driller, pump installer, well service company, treatment installer or water testing lab we can verify. Listings start from public state records — Washington Ecology’s licensed drillers, L&I contractor registrations and Ecology-accredited labs — and each company’s own website. A company can’t pay to be added, and can’t pay to be removed. Every listing cites its sources and shows when it was last verified.

A listing only appears under a kind of work if it holds the license that work needs: drilling needs an Ecology water well operator license; pump, well service and treatment work needs an L&I registration. Each license is checked before the listing is published and again every week.

The public record on each listing

Each listing with an L&I license shows that company’s Washington L&I record for the last 5 years, refreshed every week:

Unpaid fines, open lawsuits and unpaid warrants are shown whatever their age. Routine paperwork lapses, like a late renewal, are left out. We never publish the names of the people involved — plaintiffs, owners or workers.

A Clean L&I record badge means none of the above in the last 5 years. A record isn’t proof of poor work: busy companies do more jobs and collect more records, and many fines are about paperwork or staff certificates. Read the details, ask the company, and check the full record on L&I’s Verify tool. L&I’s records don’t include Ecology’s driller enforcement, or complaints made only to the company, review sites or the Attorney General.

How search and lists are ordered

There are no sponsored results, “featured” slots or affiliate links, and we don’t sell your details or your search to anyone. Analytics are cookieless and don’t follow you to other sites.

Corrections

If something here is wrong — including a public record that has since been resolved — email hello@pacwestwells.com with a link to the page and a source we can check. Records come straight from L&I, so a record that’s wrong there needs correcting with L&I too.
