The line between a repair and a repipe comes down to pattern and scope. A single leaking joint or corroded section of pipe is usually a repair. But when leaks keep returning in different spots, water quality is degrading, and your plumber is spending more time in your crawl space than you’d like, the pipes themselves — not just individual fittings — have reached the end of their useful life. Repiping replaces the distribution piping throughout the home with new material, solving the root cause rather than chasing symptoms.

Warning Signs That Point Toward Repiping

No single symptom automatically means you need a full repipe, but several together paint a clear picture. The most telling signs include:

  • Recurring leaks in multiple locations — if you’ve patched three or four spots over the past few years, the pipe walls are failing broadly, not at isolated weak points
  • Discolored water — brown, orange, or rust-colored water at the tap indicates corrosion inside galvanized steel pipes shedding into your water supply
  • Significantly reduced water pressure throughout the house — interior pipe scale buildup gradually narrows the effective pipe diameter, choking flow
  • Pipes that are 50+ years old, particularly galvanized steel — this material has a lifespan of roughly 40–70 years and is known to corrode from the inside out
  • Pinhole leaks in copper pipes — while copper lasts longer than galvanized, aggressive water chemistry or manufacturing defects can cause widespread pinhole corrosion

Pipe Materials and Their Typical Lifespans

Understanding what type of pipe you have helps estimate where you are in the lifecycle. Galvanized steel, common in Denver homes built before the 1970s, typically lasts 40–70 years. Its interior rusts progressively, first discoloring water and then restricting flow before leaks develop. Copper is more durable — often lasting 50–70+ years — but Colorado’s slightly acidic water in some municipalities can accelerate pinhole corrosion in Type M copper (the thinner wall variety). Polybutylene, a gray plastic pipe installed in some homes from the late 1970s through the mid-1990s, has a poor track record and many insurance companies will not cover homes that still have it.

Modern repiping typically uses PEX (cross-linked polyethylene) tubing, which is flexible, frost-resistant, and chemically resistant to the mineral-heavy water common throughout the Front Range. PEX’s flexibility is also an asset in Colorado homes where freeze-thaw cycles stress rigid pipe connections.

The Cost Calculation: Repair vs. Repipe

When repairs have become routine rather than exceptional, the cumulative cost — including service calls, drywall repairs, and water damage remediation — can easily exceed what a repipe would have cost. A repipe is a significant upfront investment, but it comes with decades of reliable service and eliminates the ongoing uncertainty of when the next leak will show up and where. For pricing on your specific situation, Done provides free estimates; financing options are also available through our financing page to help manage the upfront cost.

How a Plumber Evaluates Whether You Need to Repipe

A thorough assessment starts with understanding the history — how many leaks, what locations, over what timeframe. The plumber will inspect accessible sections of pipe in the crawl space, basement, utility areas, and behind access panels. Water pressure tests reveal whether interior scale has narrowed the pipes. In some cases, a camera inspection or water quality test helps confirm the condition of pipe walls and whether corrosion byproducts are entering the water. This information together gives a clear picture of whether targeted repairs make sense or whether a full repipe is the more practical path.

What the Repiping Process Looks Like

Modern repiping, especially with flexible PEX tubing, is less invasive than many homeowners expect. Crews work methodically room by room, typically keeping water on to most of the house while each section is completed. Drywall openings are made at strategic points to run new lines, and your plumber can often coordinate with a drywall contractor for repairs. Most whole-home repipes on a standard residential property are completed in two to three days. Done’s team has extensive experience repiping Front Range homes, including older Denver neighborhoods with aging galvanized supply lines.
