FAQs
What is PEX plumbing and why is it recommended for pipe upgrades in Kelso?
PEX (cross-linked polyethylene) is a flexible, durable plastic piping material used to replace old copper, galvanized, or poly-butylene lines. It is corrosion-resistant, withstands freezing better than rigid pipe, and is quicker to install because it bends around corners with fewer fittings. For Kelso homeowners, PEX is ideal for our seasonal temperature swings and the mineral content in local water, which can accelerate corrosion in metal pipes.
How long does a typical whole-home PEX repipe take?
Most single-family homes in Kelso can be completely repiped with PEX in 2–4 days. The first day is spent running new PEX lines through walls, ceilings, and crawl spaces; the second day involves connecting fixtures and pressure testing; any remaining time is for drywall repair and cleanup. Larger homes or properties with difficult access (e.g., slab foundations) may take up to a week, but you’ll usually have water restored every evening.
Will my water be shut off during the upgrade?
Yes, but only temporarily. Our team typically shuts off the main water line in the morning while we disconnect the old piping and start running the new PEX. We restore water service to one bathroom as soon as possible—often by midday—and full service is restored by the end of each workday. We coordinate with you in advance so you can fill containers or make alternate arrangements if needed.
How much does a PEX pipe upgrade cost in Kelso?
Pricing depends on home size, number of fixtures, and the accessibility of existing pipes, but most Kelso repipes fall between $4,000 and $9,000 for a 2- to 3-bath home. PEX itself is less expensive than copper, and faster installation keeps labor costs down. We provide a detailed, itemized quote after a free in-home inspection, and financing options are available for qualified homeowners.
Is PEX code-approved and safe for drinking water?
Absolutely. PEX has been approved by the International Residential Code (IRC) and the Uniform Plumbing Code (UPC) used by the City of Kelso and Cowlitz County. It is certified to NSF/ANSI 61 for potable water, meaning it does not leach harmful contaminants. All fittings we use are lead-free brass or polymer, and the entire system is pressure-tested and inspected by local building officials before final approval.
What kind of warranty and lifespan can I expect?
The PEX tubing we install carries a manufacturer’s 25-year limited warranty, and our workmanship is covered for 10 years. In practice, PEX has a life expectancy of 50 years or more when installed correctly and kept away from direct UV exposure. Should any leak or fitting issue arise during the warranty period, we repair or replace it at no cost to you.
