Whole-Home Repiping in Woburn, MA

What is whole-home repiping?

Whole-home repiping replaces all or most of the water supply pipes in a house. New lines, usually PEX or copper, run from the main shutoff to every fixture. Old lines under the slab are capped and left in place. It's the long-term fix when pipes keep leaking in different spots.

Woburn has a lot of older housing, from early 1900s colonials near the center to mid-century capes and ranches. Many still have original galvanized steel or aging copper. When those pipes reach the end of their life, fixing one leak at a time gets expensive.

Signs your home needs repiping

• Two or more slab leaks or pinhole leaks in a few years.
• Galvanized steel pipes (gray, threaded joints), which rust from the inside.
• Rusty, brown or metallic-tasting water.
• Low water pressure across the house.
• Green corrosion or crusty spots on copper pipes.
• Pipes that are 50 or more years old.

How does whole-home repiping work?

A plumber maps every fixture, plans new pipe routes through walls, ceilings and the basement, then installs the new system in stages. Each fixture is switched to the new lines, the old lines are capped, and the whole system is pressure tested. Wall openings are patched at the end.

1. Inspect and plan. The plumber checks pipe condition, fixture count and access routes.
2. Protect the home. Floors and furniture are covered.
3. Open small access points in walls and ceilings where pipes must pass.
4. Install new lines from the main shutoff to each fixture, with new shutoff valves.
5. Switch over and test. Water is usually off only for short periods each day.
6. Patch and clean up. Drywall is repaired and the work area is cleaned.

How much does whole-home repiping cost?

National 2026 cost guides put whole-home repiping at about $4,000 to $15,000 or more. Size of the home, number of bathrooms, pipe material and wall access drive the price. Homes with open basements often cost less to repipe, because lines can run along exposed ceiling joists.

• Square footage and number of floors
• Number of bathrooms and fixtures
• PEX vs. copper
• Plaster walls (common in older Woburn homes) vs. drywall
• Drywall or plaster repair and painting
• Permits and inspection

Is repiping ever an emergency?

Repiping itself is a planned project. But if a line is leaking now, call for emergency slab leak repair to stop the water first. A plumber can isolate or reroute the failed line, then plan the full repipe.

Repipe or keep repairing?

A simple rule: one slab leak in an otherwise healthy system can be spot repaired or rerouted. A second or third leak is a sign the pipe is failing as a whole. At that point each repair adds to a bill that could have gone toward new pipe. Start with slab leak detection and ask the plumber to rate the condition of your pipes.

How to prepare for a repipe

• Clear a path to the basement, water heater and main shutoff.
• Move furniture away from walls where access holes will be cut.
• Plan for short water shutoffs during the day.
• Ask whether patching, painting and permit fees are in the quote.
• Ask the plumber to add shutoff valves at each fixture for easier repairs later.

A repipe is also a good time to check your water pressure and add a pressure reducing valve if needed. It protects your new pipes and fixtures for years to come.
