What Is Whole House Repiping?
Whole house repiping — sometimes called a full home repipe service or house plumbing replacement — means replacing every supply line in your home. Not just the pipes that are visibly leaking, but the entire water distribution system: the main line coming in from the meter, every branch line running to each room, and the supply connections to every fixture and appliance.
It's a bigger job than most repairs, but it's also a permanent solution. When a home's supply system has reached the point where individual repairs are masking a wider failure — low pressure, rust-tinted water, recurring pinhole leaks — repiping addresses the root cause rather than patching symptoms.
Kirkland's housing stock ranges from 1960s and 1970s homes near downtown and the waterfront to 1980s and 1990s construction in Juanita and Bridle Trails, to newer builds farther out. The older the home, the more likely it has galvanized steel or early copper supply lines that are now showing their age. Many Kirkland homes were also built during the polybutylene era (roughly 1978 to 1995) — gray plastic pipe that's a known failure risk and the most common reason we get called for a full home repipe service in this area.
Signs You Need to Repipe Your Whole House
Most homeowners don't know their supply system is failing until something visible happens. Here are the signs worth paying attention to:
Low water pressure throughout the house — not at one faucet, but everywhere. This usually means buildup inside galvanized lines restricting flow.
Rust-tinted water, especially in the morning — the first draw of water sitting in corroded galvanized lines comes out orange or brown.
Multiple pinhole leaks in a short period — one pinhole is a repair. Two or three in different locations in the same year is a pattern.
Pipes that are gray plastic, stamped PB2110 — that's polybutylene. If you see it in your crawl space or behind access panels, it needs to go.
Your home was built before 1990 and hasn't been repiped — galvanized supply lines have a typical service life of 40 to 70 years. Many Kirkland homes are in or past that window.
Banging or clanging in the walls when water runs — can indicate pipe movement from pressure fluctuations in a deteriorating system.

PEX vs Copper for Whole House Repipe in Kirkland
This is the question we answer most often on repipe projects. Here's the honest version:
Kirkland receives its water from the Seattle Public Utilities watershed system, which produces soft, low-mineral water — favorable for both materials. We install both PEX-A and copper, and give you a straight recommendation based on your home and goals.
For a deeper breakdown, see our PEX repiping guide and copper repiping guide.
How Long Does Whole House Repiping Take?
Most Kirkland whole house repipes complete in one to three days on-site. Here's what that timeline looks like:
Day 1 — We map the existing supply system, open access points, and begin running new lines. Water is off during work hours; we restore pressure at the end of each day so you're not without water overnight.
Day 2 (most homes) — All new lines are connected, shut-off valves are replaced at each fixture, and the system is pressure-tested.
Day 3 (larger homes or complex layouts) — Finishing connections, final pressure test, and drywall patch to paint-ready.
The full timeline from first call to a completed, permitted, city-inspected repipe is typically two to four weeks — most of that is City of Kirkland permit processing. We submit permits immediately upon signed approval.
Do I Need a Permit to Repipe in Kirkland WA?
Yes. Under the City of Kirkland Building Permits requirements, whole-home plumbing replacements require a permit before work begins. The permit triggers a rough-in inspection before walls are closed and a final inspection upon completion.
Washington State L&I also requires that all plumbing work beyond minor maintenance be performed by a licensed contractor. We hold an active Washington State plumbing contractor license and pull every permit ourselves — it's non-negotiable. An unpermitted repipe creates a disclosure problem at resale and can void your manufacturer's material warranty.
What the Repipe Process Looks Like at Eastside Repipe

Free walkthrough and written estimate — we assess the existing system, identify the pipe material, and give you an itemized quote before anything starts.
Permit filing — we submit to the City of Kirkland immediately upon approval.
Installation — PEX-A or copper run through the home, with access points kept to a minimum by using PEX's flexibility around framing.
City rough-in inspection — required before walls are closed.
Drywall patch to paint-ready — every access point gets closed, taped, and textured.
Pressure test and walkthrough — we test every line, run every fixture, and walk you through the completed system.

Best Whole House Repiping Contractors in Kirkland: Why Eastside Repipe
We're not the largest plumbing company on the Eastside. That's intentional. Ramin Shahbaziasl is personally involved in every repipe we do — which means the person who walks your home and writes your quote is the same person managing the job. When something unexpected comes up behind the walls (and on Kirkland's older homes, it often does), you're not waiting on a dispatcher.
A few things that separate a professional pex repipe installation from a rushed one:
Proper expansion fittings throughout — not push-to-connect shortcuts in wall cavities
New shut-off valves at every fixture — the ones on older Kirkland homes are often seized
Ice-and-water shield at vulnerable areas per Washington State code
Clean drywall patches that don't require a separate contractor to finish
Frequently Asked Questions
1. How much does whole house repiping cost in Kirkland?
Cost depends on home size, pipe material, and access complexity. We don't publish ranges without a verified local source — every Kirkland home is different, and a number without context can mislead. Call 425-331-2011 for a free written estimate on your specific property.
2. How long does a whole house repipe take?
Most Kirkland homes complete in one to three days on-site. Total timeline from first call to a permitted, city-inspected repipe is two to four weeks — the majority is permit processing through the City of Kirkland.
3. Do I need a permit to repipe my house in Kirkland?
Yes. The City of Kirkland requires a permit for whole-home plumbing replacement, with a rough-in inspection before walls are closed. Washington State L&I requires licensed contractor work. Eastside Repipe And Plumbing handles all permit filing on every project.
4. Is PEX or copper better for repiping?
PEX-A is the better choice for most Kirkland homes — lower cost, faster install, freeze-tolerant, and well-suited to Kirkland's soft SPU watershed water supply. Copper is better for very long-term ownership (60 to 70-year lifespan) or when walls are already open. We install both and give you a straight answer based on your home and goals.
5. How do I know if my Kirkland home needs repiping?
The clearest signs: low pressure throughout the house, rust-tinted morning water, multiple pinhole leaks in a short period, gray plastic pipe stamped PB2110 (polybutylene), or a home built before 1990 that hasn't been repiped. Any one of these warrants a free walkthrough — call 425-331-2011.
