AAA Organized Plumbing provides whole-house and partial repiping services for homes and commercial properties throughout Mendocino, Sonoma, Lake, and Napa Counties. Northern California has a significant inventory of homes built between the 1940s and 1980s with galvanized steel or polybutylene water supply piping that has reached or exceeded its useful life. Corroded galvanized pipes restrict water flow, contaminate water with rust particles, and develop pinhole leaks that cause hidden water damage behind walls and under floors. Polybutylene pipes, once common in homes across Redwood Valley, Willits, and Covelo, are prone to sudden brittle failure without warning. Repiping replaces these failing systems with modern copper or PEX piping that restores full water pressure, eliminates chronic leak repairs, and protects your home for decades. Call (707) 200-3159 for a free repiping evaluation.
Certain warning signs indicate your plumbing system is approaching or has passed the point where spot repairs are no longer cost-effective.
Common indicators include rusty or discolored water from hot and cold taps, noticeably reduced water pressure throughout the house, recurring pinhole leaks in different locations, water stains on ceilings or walls indicating hidden leaks, and visible corrosion on exposed pipes in crawl spaces, basements, or utility rooms. If you’re calling for leak repairs more than once or twice a year, repiping typically provides better long-term value than continuing to patch an aging system.
Galvanized steel was the standard residential water pipe material from the 1940s through the 1970s. After 40–60 years, the zinc coating that protects galvanized pipe corrodes away, exposing bare steel that rusts from the inside out. This internal corrosion progressively narrows the pipe bore, restricting water flow and producing the rusty water, low pressure, and pinhole leaks that plague older homes in Ukiah, Mendocino, Fort Bragg, and throughout the region.
Polybutylene (PB) piping was installed in millions of homes from the late 1970s through the mid-1990s. This gray or blue flexible plastic piping deteriorates from contact with chlorine and chloramine disinfectants in municipal water, becoming brittle and developing cracks that cause sudden flooding. Properties in subdivisions built during this era across Potter Valley, Calpella, and Talmage should have their piping evaluated if it hasn’t already been replaced.
We offer multiple piping material options based on your home’s layout, budget, and water conditions.
Cross-linked polyethylene (PEX) piping has become the preferred choice for residential repiping due to its flexibility, corrosion resistance, freeze resistance, and faster installation time compared to rigid piping. PEX routes through walls and floors with fewer fittings and connections than copper, reducing potential leak points. Color-coded red and blue lines simplify identification of hot and cold supply. PEX is particularly well-suited for Northern California homes with crawl space access, where flexible routing saves significant labor time.
Copper remains a premium piping choice valued for its proven longevity (50+ years in most water conditions), antimicrobial properties, and high resale value perception. Type L copper is our standard for residential supply lines, offering wall thickness appropriate for residential water pressure. Copper is the preferred choice for properties with aggressive water chemistry or for homeowners who prioritize the longest possible service life.
Traditional trunk-and-branch repiping runs a main line with branches splitting off to each fixture. Manifold systems run individual home-run lines from a central distribution point to each fixture, similar to a breaker panel for plumbing. Manifold systems provide more consistent pressure across all fixtures, allow individual fixture shut-off without affecting the rest of the house, and reduce fitting connections inside walls. We recommend and install both configurations based on home layout and homeowner preference.
Repiping costs depend on home size, number of fixtures, pipe material selected, and accessibility (slab vs. crawl space vs. basement). Here are general ranges:
Whole House PEX Repipe (2-bathroom home): $4,000–$8,000
Whole House PEX Repipe (3+ bathroom home): $7,000–$15,000
Whole House Copper Repipe (2-bathroom home): $6,000–$12,000
Partial Repipe (specific problem areas only): $1,500–$4,000
Manifold System Installation (add-on): $500–$1,500 depending on fixture count
Cost factors specific to Northern California include:
Homes built before 1990 in Ukiah, Willits, Lakeport, and surrounding communities represent the bulk of our repiping work. Many of these homes have original galvanized steel piping that has reached end-of-life, producing rusty water, low pressure, and frequent leaks. A complete PEX or copper repipe restores water quality and pressure while eliminating the ongoing cost of repeated repairs.
Real estate agents and home inspectors throughout Northern California flag galvanized and polybutylene piping as material defects during transactions. Repiping before listing eliminates this negotiation point, prevents buyer requests for price reductions, and provides a strong selling feature that demonstrates the home’s updated infrastructure.
Apartment buildings, duplexes, and commercial properties with aging supply piping require coordinated repiping that minimizes tenant disruption. We plan multi-unit repiping projects in phases – typically completing each unit in 1–2 days – to maintain habitability throughout the project.

Most 2–3 bathroom homes can be repiped in 2–3 days. Larger homes with complex layouts, multiple stories, or slab foundations may take 4–5 days. We provide a specific timeline in our proposal and coordinate water shutoff scheduling to minimize disruption – typically water is off during work hours and restored each evening.
Both are excellent choices. PEX offers lower material cost, faster installation (reducing labor cost), freeze resistance, and flexibility that simplifies routing. Copper provides the longest proven track record (50+ years), antimicrobial properties, and strong resale value perception. For most Northern California homes, we recommend PEX for its combination of performance, cost-effectiveness, and durability. We’re happy to discuss both options during your evaluation.
Some access cuts in drywall are necessary for routing new pipe through walls. We plan access points strategically to minimize the number and size of cuts. In homes with crawl space access – common throughout our Mendocino and Sonoma County service area – most pipe routing is done underneath the home, significantly reducing drywall disturbance. We provide a clear access plan before starting work.
Galvanized steel pipes are silver-gray when new but develop a rough, dark gray or brownish surface as they corrode. They’re magnetic – a magnet will stick to them. Polybutylene pipes are gray, blue, or black flexible plastic, typically 1/2 to 1 inch diameter, with copper or plastic crimp rings at connections. Check visible pipes in your crawl space, basement, or at the water heater connections. If you’re unsure, we’ll identify your pipe type during a free evaluation.
Yes. California building code requires a plumbing permit for whole-house repiping. The permit ensures work is inspected by the local building department for code compliance and safety. We handle all permit applications and inspection coordination as part of our service.
In most cases, yes – significantly. Corroded galvanized pipes can lose 50–75% of their internal diameter to rust buildup, severely restricting flow. New PEX or copper piping delivers full-bore water flow to every fixture. Homeowners frequently describe the difference as dramatic, especially at showers and kitchen faucets.
