Residential & Commercial Plumber in Kirkland, WA


We’re Goldstar Plumbing, a family-owned, veteran-operated plumbing company that has been working on homes and businesses across King and Snohomish Counties for years, and Kirkland is one of the communities we know well. Whether you’re in a 1960s rambler near Norkirk, a newer townhouse off Totem Lake Boulevard, or a retail space along Central Way, we understand how this city’s housing stock, soil, and weather affect the pipes and fixtures underneath it.

We handle residential plumber calls and commercial plumber contracts alike, which means the same licensed, insured team that re-pipes a kitchen in Houghton can also keep a restaurant’s grease line running clean downtown. Our focus is simple: diagnose it right the first time, explain the options in plain language, and back the work with a real guarantee.

Why Kirkland Homes and Businesses Have Specific Plumbing Needs

Kirkland’s plumbing problems are not generic. The city sits directly on Lake Washington, which means homes in Moss Bay and along the waterfront deal with a high water table and slow-draining yards during the wet months, while properties up in Finn Hill, Bridle Trails, and North Rose Hill often sit on wooded, root-heavy lots where mature trees send roots straight into clay or cast iron sewer laterals.

The age of the housing stock varies block by block. Older single-family homes around Norkirk, Market, and Everest were often built with galvanized steel supply lines that are now decades past their intended service life and prone to internal corrosion and reduced water pressure. Meanwhile, the condo and townhouse growth around downtown Kirkland, Totem Lake, and the Google campus area near Moss Bay means we’re just as often troubleshooting shared-wall plumbing, tankless water heaters, and tight mechanical closets as we are replacing old galvanized pipe.

Add in the Pacific Northwest’s long, wet winters and the seasonal freeze snaps that occasionally hit the Eastside, and Kirkland properties see a predictable pattern: sewer backups and root intrusion rising in the fall and winter rains, frozen or burst exterior lines during cold snaps, and sump pump demand in low-lying lots near the lake and Forbes Creek. We size our service calls around that pattern rather than treating every job the same.

Plumbing Services We Offer in Kirkland


Repairing a leaking sink drain

Residential Plumbing Repair

A plumbing repair in Kirkland usually comes down to one of a few causes: aging galvanized pipe in older homes, fixture wear in condos, or root intrusion in sewer lines near wooded lots. We troubleshoot leaky faucets, running toilets, failing shutoff valves, and pipe leaks inside walls and crawlspaces, then repair or replace only what’s actually failing.

Commercial Plumber Services

Commercial plumbing in Kirkland covers everything from restaurant grease interceptors on Central Way to multi-unit backflow testing for office buildings near Totem Lake. We work around your operating hours, handle code-required backflow and grease trap maintenance, and keep a direct line open for property managers who need a plumber who shows up on schedule.

Emergency Plumber

An emergency plumber call in Kirkland is answered 24/7, and for true emergencies like burst pipes or sewage backups we aim to be on site the same day. Burst pipes during a cold snap, sewage backups after a heavy rain event, and water heaters that fail overnight don’t wait for business hours, and neither do we.

Water Heater Installation

Water heater installation in Kirkland depends heavily on the home: tight mechanical closets in downtown condos usually call for a tankless unit, while larger Finn Hill or Bridle Trails homes often do better with a high-capacity tank. We install standard, hybrid, and tankless systems and size the unit to your household or business, not the other way around.

Drain Cleaning

Drain cleaning in Kirkland most often means clearing root intrusion in older clay sewer laterals near Norkirk and Everest, or grease and mineral buildup in kitchen and bathroom lines closer to downtown. We clear the clog, then use a sewer camera when needed to confirm whether the root cause is a one-time blockage or a line that needs longer-term repair.

Sump Pump Installation & Repair

Low-lying lots near Lake Washington, Forbes Creek, and the Totem Lake basin see real groundwater pressure during the rainy season. We install and service sump pumps so basements and crawlspaces in those areas stay dry through King County’s wet winters.

New underground drainage lines

Leak Detection & Repair

A slow leak inside a wall or under a slab can run up a water bill for months before it’s visible. We use acoustic and moisture-based leak detection to find the source without tearing out more drywall or flooring than necessary.

Water Service Line Repair & Replacement

Main water line failures are common in Kirkland’s older neighborhoods where galvanized or aging copper service lines are reaching the end of their lifespan. We repair and replace service lines with minimal disruption to landscaping and driveways.

Hydro Jetting & Sewer Line Camera Inspections

For sewer lines dealing with repeated clogs, often from root intrusion along the tree-lined streets of Bridle Trails or Finn Hill, we use hydro jetting to clear the line without chemicals, then run a camera inspection to show you exactly what’s happening underground before recommending repair or replacement.

Trenchless Sewer Line Replacement

When a sewer line under a mature landscape or a downtown sidewalk needs full replacement, pipe bursting and cured-in-place pipe lining let us do it without excavating the yard, driveway, or hardscape.

Frequently Asked Questions About Plumbers in Kirkland


How much does a plumber cost in Kirkland?

Most standard plumbing repairs in Kirkland run between a basic service call fee and a few hundred dollars, while larger jobs like water heater replacement or sewer line repair cost more depending on access and materials. We provide an upfront, written price before starting any work, so there are no surprises on the invoice. [NEEDS INPUT: specific pricing ranges or minimum service call fee, if you want to publish them]

Do you offer emergency plumbing in Kirkland after hours?

Yes, we offer 24/7 emergency plumbing service in Kirkland for burst pipes, sewage backups, and water heater failures. Call us any time and we’ll walk you through immediate steps to limit damage while we get a plumber on the way.

Why does my Kirkland home keep getting sewer line clogs?

Repeated sewer clogs in Kirkland are most often caused by tree root intrusion into older clay or cast iron lines, especially on wooded lots in Finn Hill, Bridle Trails, and North Rose Hill. A camera inspection can confirm whether roots, pipe bellies, or buildup are the real cause so we fix the source instead of just clearing the symptom.

Is a tankless water heater a good fit for a Kirkland condo?

Tankless water heaters are often a strong fit for Kirkland condos and townhouses because they free up closet space and handle the lower, steady hot water demand typical of smaller units. Larger single-family homes with higher simultaneous hot water use sometimes still do better with a high-capacity tank, which we can help you evaluate.

Do you work on commercial plumbing for Kirkland businesses?

Yes, we service commercial plumbing for Kirkland businesses, including grease interceptor maintenance, backflow testing, and repair work scheduled around your operating hours. We work with property managers and business owners across downtown Kirkland and the Totem Lake commercial corridor.

How fast can a plumber reach me in Kirkland?

For standard appointments we typically schedule within the same week, and for true emergencies we aim for same-day response anywhere in Kirkland. Call ahead so we can give you the most accurate arrival window for your specific neighborhood.
