Who We Are

Licensed, Insured, and Local to Mercer Island

Street Wise - Plumbing isn't a call center that forwards your job to whoever's cheapest that week. Our technicians carry state licensing, they're background-checked before they're handed a company vehicle, and every truck rolling through Mercer Island, WA is stocked for the repairs we see most in this climate and these homes.

Experience matters here — a technician who's replaced a hundred water heaters spots the corroded shutoff valve or undersized gas line before it becomes a callback. That's the level of eye we send to every Mercer Island job.

Training doesn't stop after licensing. Our Mercer Island team runs regular refreshers on code updates, new fixture technology, and the material mix specific to Mercer Island, WA construction, so a repair holds up to inspection, not just to a quick test run.

Signs You Need a Plumber

Don't Wait For a Small Leak To Become a Flood

Plumbing rarely fails without warning — it usually gives you a week or two of small signals before the big one. Watch for these.

Our Core Services

Plumbing Solutions Built For Every Situation

Emergency Plumbing

When water's actively coming out somewhere it shouldn't, minutes matter more than money. Our on-call technicians in Mercer Island are dispatched with the parts and equipment to handle burst pipes, failed water heaters, and overflowing fixtures on the first trip.

Residential Plumbing

From a running toilet that's quietly inflating your water bill to a full re-pipe of an older Mercer Island home, our residential team handles the everyday and the extensive with the same attention to detail.

Commercial Plumbing

Restaurants, offices, and retail spaces in Mercer Island, WA can't afford extended downtime over a plumbing issue. Our commercial team is equipped for grease trap service, backflow testing, and multi-fixture repairs on a schedule that respects your operating hours.

Drain & Sewer Service

Our drain team runs camera line inspections before recommending anything invasive, so you're not paying for a dig-up when a hydro-jetting service would clear it.

Water Heater Repair & Install

Whether it's a pilot light that won't stay lit or a full tank-to-tankless conversion, our technicians are certified on both gas and electric systems common in Mercer Island, WA homes.

Leak Detection & Repair

Rather than opening walls on a hunch, our technicians run listening equipment across the suspected line first, marking the leak within a foot or two before any cutting begins.

Fixture Installation & Repair

We replace failing shutoff valves and supply lines as part of fixture work rather than reconnecting new fixtures to old, brittle hardware that's likely to fail next.
