Why West Seattle Homes Need Repiping: The Galvanized Era
If your home was built before 1970—which describes most homes in the Admiral District, Alaska Junction, and Fauntleroy—it was likely plumbed with Galvanized Steel pipes. At the time, this was the standard. Steel pipes were dipped in molten zinc to prevent rust.
However, over decades, that zinc coating wears away. The steel underneath begins to rust from the inside out. As the rust builds up (tuberculation), the internal diameter of the pipe shrinks, restricting water flow like a clogged artery. Eventually, the pipe walls become so thin they develop pinhole leaks or snap off at the threads.
Severely corroded galvanized pipes can leach lead (from old solder or the zinc coating itself), cadmium, and rust into your drinking water. If your tap water has a metallic taste or reddish tint, it's time to test your water or inspect your pipes.
4 Signs Your West Seattle Home Needs Repiping
Low Water Pressure
The most common sign. If your shower pressure drops when someone flushes the toilet, or if the water just feels "weak" everywhere, the pipes are likely choked with rust buildup.
Discolored Water
If you turn on a faucet after being away for the weekend and the water runs brown, yellow, or red, you are seeing active rust from the inside of your pipes washing out.
Recurring Leaks
Fixing one leak only to have another appear weeks later is the classic sign of systemic failure. The pipes are failing uniformly; patching one spot just shifts the pressure to the next weak point.
Visible Corrosion
Check exposed pipes in your basement or crawlspace. If you see white powdery buildup (oxidation), rust spots, or dimpling on the outside of the pipes, they are deteriorating.
Repiping Materials: PEX vs. Copper for West Seattle Homes
We typically recommend two materials for repiping: PEX or Copper. Here is how they stack up.
PEX (Cross-linked Polyethylene)
A flexible, high-density plastic piping that has become the industry standard for residential plumbing.
Copper Piping
The traditional gold standard. Rigid metal piping that has been used for decades.
Our Whole Home Repiping Process
Site Protection & Prep
We treat your home like a museum. We lay down heavy floor protection, cover furniture with plastic, and set up dust containment barriers. We identify exactly where we need to cut to minimize damage.
Installation (1-3 Days)
We run the new PEX or Copper lines through your attic, basement, or crawlspace, dropping down into walls only where necessary. We usually keep your water ON at the end of each day so you aren't without service overnight.
The Switchover & Inspection
Once the new system is pressure-tested and leak-free, we disconnect the old galvanized pipes and switch you to the new system. A City of Seattle inspector reviews the work to ensure code compliance.
Wall Patching (Optional)
Most plumbers leave you with holes in your wall. Sasquatch partners with professional drywallers. We can include a "paint-ready" patching service in your quote so your walls look as good as new.

Whole Home Repiping FAQ
Do I have to move out during the repipe?
No! In 95% of cases, you can stay in your home. We cover everything with plastic during the day and clean up every evening. You will have water every night.
Does repiping increase my home value?
Absolutely. In the competitive West Seattle real estate market, old galvanized plumbing is a major red flag for home buyers and inspectors. A new PEX or Copper system is a selling point that assures buyers they won't have emergency leaks. Many Alki and North Admiral homeowners repipe before listing.
What about the main water line?
A standard repipe covers the pipes inside your home. The main water line (from the street to the house) is separate, but we often recommend replacing it at the same time if it is also old galvanized pipe. We offer package discounts for doing both.
