What affects your repipe price

Material: PEX vs. copper

PEX installs faster with fewer fittings and wall openings and tolerates freezing that would split rigid pipe; copper carries a 50+ year proven record. Both are fully code-compliant in Washington — the cost gap is largely labor.

Home size & fixture count

More bathrooms, stories, and fixtures mean more runs, more fittings, and more access openings. A one-bath rambler and a three-bath two-story are very different projects.

Access: crawlspace, slab, finished walls

Puget Sound homes with crawlspaces repipe faster. Slab-on-grade homes or fully finished walls and ceilings need more openings and more patching.

Patch-and-paint scope

A professional repipe maps its access openings in advance so drywall repair is a defined scope, not a surprise bill. Ask whether patching is included — Eco coordinates it in the quote.

Permits & inspection

Washington requires a plumbing permit and inspection for a repipe. A licensed, permitted job protects your home's value and your insurance — Eco includes it in your upfront price.

On failing galvanized or polybutylene pipe, every patch is a down payment on the next leak — and insurers increasingly surcharge or decline homes that keep them. A planned repipe on your schedule beats financing one through water-damage deductibles.

What’s driving costs up

  • Copper commodity prices
  • Licensed plumber shortage
  • Insurers surcharging galvanized and polybutylene homes
  • Drywall and finish-labor costs

Spread the cost over time

Qualified homeowners can finance their repipe into affordable monthly payments — quick, easy approval, and you still get today’s price.

Frequently asked questions

Should I repipe with PEX or copper?

Both are code-compliant and durable when installed correctly. PEX is usually less expensive ($8,000–$15,000 vs $15,000–$25,000 for copper), faster to install with fewer wall openings, and quieter; copper is time-proven and some owners simply prefer it. Eco recommends based on your water chemistry, layout, and budget — and installs both.

How long does a whole-home repipe take?

Most repipes finish in two to five days depending on home size. Water is typically off only during working hours and back on each evening, access openings are planned and mapped in advance, and you stay in the home throughout.

How do I know if I need a repipe instead of a repair?

Material and pattern decide it. One leak on healthy copper or PEX deserves a spot repair. Galvanized steel or polybutylene anywhere in the system, a second leak within a year, or falling pressure at multiple fixtures are systemic-failure signals — on those, every patch just buys time.

Will insurance cover a repipe?

Policies generally cover sudden water damage but not the aging pipe itself — and many insurers now surcharge, exclude, or decline homes with known polybutylene or failing galvanized supply lines. A repipe protects both the house and your insurability, and costs dramatically less on your schedule than after a ceiling comes down.

    “The electrician, Max, found the problem in less than 30 minutes. He located a loose wire that had cut power to two rooms and corrected it. Max is a very pleasant person and professional in every way. I'll recommend him and the company to anyone with electrical problems.”

    “Our furnace died the Sunday before Christmas. The dispatcher rearranged the schedule to send someone Monday, and the crew came out promptly and got the new furnace installed early afternoon. Excellent, knowledgeable, and responsive — Eco is my go-to now. Couldn't be happier!”
