Before you sign

What to ask a Bellevue contractor first

01
How large an opening in floor, wall or slab is expected, because minimizing access limits the later restoration work?
02
For a slab leak, is a spot repair through the concrete or an overhead reroute proposed, and why that choice?
03
Will a written report with photographs and marked locations be provided, since insurers usually require proof of cause and position?

Before anyone touches a pipe

Verify the license. It takes two minutes.

Who licenses the work: Washington State Department of Labor & Industries (L&I).
Who pulls the permit: Bellevue Development Services — the licensed contractor, never the homeowner.
What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.

Local factor

Soft, low-alkalinity water and copper corrosion west of the Cascades

Water on the western side of Washington is naturally soft and low in alkalinity, which is the opposite problem from the hard-water states: soft, poorly buffered water is corrosive to copper and to the lead solder used in joints before 1986. Utilities dose corrosion control treatment to raise pH and reduce metal release, which is why pinhole leaks and blue-green staining are less common than untreated water would produce. In houses with pre-1986 copper plumbing the sensible responses are running a tap until the water is cold before drawing it for drinking or cooking, having suspect joints assessed, and treating repeated pinhole leaks as a system-level problem rather than a run of bad luck. Current figures for any given system belong in the water provider's annual water quality report.

Answers first

Leak Detection in Bellevue — common questions

How do I know if I have a hidden leak?

The simplest test: turn off every fixture and appliance that uses water, then watch the water meter's low-flow indicator for 15–20 minutes. Any movement means water is leaving the system somewhere. That test does not tell you where — it tells you that detection is worth paying for.

Is a slab leak an emergency?

It is urgent rather than instantaneous. A slab leak will keep eroding fill under the foundation and driving up the bill for as long as it runs, so it should be located quickly — but you generally have hours to days, not minutes, unless water is entering the living space.

Will detection damage my floor?

Modern detection is designed to avoid that: the point of acoustic, thermal and tracer-gas equipment is to make one small opening instead of several exploratory ones. Ask the contractor what restoration is and is not included before work starts.

Do I need a permit for plumbing work in Bellevue?

Permits in Bellevue are issued by Bellevue Development Services. As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.

How should a leak detection quote be compared?

Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.

Who handles the permit for leak detection in Washington?

The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.

What warranty applies to the work?

Whatever the contractor offers in writing — PlumberWashington is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.

How does the callback request work?

The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
