Is it time to replace the pipes?
One leak does not mean the whole house needs new pipe. A split from a freeze or a bad fitting is a repair. A pattern is different, and the pattern is what tells us repiping is worth considering.
The clearest signal is repeat failures in pipe of the same age and type. Pinholes in different rooms, green crust at many joints, and fixtures that deliver less water than they used to all point to a system wearing out from the inside.
Signs the supply pipes are reaching the end:
- Brown or orange water that runs for a minute after a fixture has been idle.
- Low pressure at several sinks and showers while the street pressure is fine.
- More than one leak in the last few years, in different parts of the house.
- Visible corrosion, flaking or rust-colored stains on exposed pipe.
- Gray or blue plastic pipe in the basement, which may be polybutylene.
Which pipes tend to fail, and why
Age alone is a weak guide. The material and how it was installed matter more.
| Pipe type | What goes wrong | Our view |
|---|---|---|
| Galvanized steel | Zinc coating wears off, rust builds inside, the opening narrows and pressure falls | Replace once leaks or low flow appear. Patching rarely holds for long |
| Polybutylene (gray or blue plastic) | Fails at fittings and degrades with water chemistry. Installed roughly from the late 1970s into the mid-1990s | Replace. It is a known problem material |
| Older copper | Pinholes, thin walls, failing solder joints | Judge case by case. Sound copper can stay. Pitted copper should go |
| Lead | Soft metal pipe or lead solder in very old work | Replace, and ask the water supplier about records |
PEX or copper: choosing the new pipe
Both materials are reliable when installed by a licensed plumber. The choice depends on your house, how much of it can be opened, and your preference. We explain the trade-offs without pushing one.
| Factor | PEX | Copper |
|---|---|---|
| Installation | Flexible tubing snakes through walls with fewer cuts and joints | Rigid, soldered or fitted at each turn, so more access is needed |
| Freeze tolerance | Expands somewhat, so a freeze is less likely to split it | Can split if water freezes inside |
| Corrosion | Does not corrode or pinhole | Can pit in aggressive water, though lasts decades in many homes |
| Heat and sunlight | Not for exposed outdoor runs, since UV damages it | Handles heat and light well |
| Disruption | Usually less drywall opened | Often more cutting |
| Appearance of exposed runs | Plastic look | Traditional metal look |
Neither material is right for every job. In a basement with open joists, copper can be a fine choice. In a finished two-story with few access points, PEX is often the practical one.
How a repiping job unfolds
We plan the work around the way you live in the house.
- Walk-through and map. The plumber traces the existing lines, checks the main shut-off and meter, and notes where the new runs can go.
- Written plan and price. You receive the scope, the pipe type and a clear price before anyone cuts anything.
- Permit. Replacing supply piping needs a plumbing permit pulled by a licensed plumber, and the work is inspected.
- Rough-in. New lines are run to each fixture, often through the same walls and chases as the old ones.
- Connect, test and inspect. We tie in, pressure test the system and arrange the inspection before closing up.
Phased work and living in the house
Repiping does not have to mean a week without water or a house torn open all at once. Many homes are done in phases: the basement and exposed runs first, then the kitchen and bathrooms, then the remaining branches.
Water is shut off for part of each work day, and the plumber tells you when it will be back. Phasing also lets you spread the cost, and you can pair it with other renovation work, such as a bathroom remodel covered under plumbing installation, so walls are opened once.
If you plan a full renovation, tell us before cabinets and tile go in. Running new pipe behind finished surfaces costs far more than running it first.
Drywall, access holes and patching
To reach pipe inside walls we cut small, neat access openings, typically at the top and bottom of a wall cavity or beside a fixture. In an unfinished basement, most of the work happens in open joists with no wall damage at all.
We leave openings cut square and clean so patching is straightforward. Plastering, painting and texturing are not part of plumbing work, so plan on a drywall finisher or your own painter afterward.
Call to talk through the pipe you have now. We schedule walk-throughs ahead, and same-day visits are possible when the calendar allows.
Milford, MA: water, permits and old houses
Milford's public water is dosed with zinc orthophosphate and a pH adjuster so it is gentler on pipe walls. That slows corrosion going forward, but it does not reverse decades of rust inside old galvanized pipe, so a house with failing galvanized needs new pipe regardless.
Plumbing permits are pulled by licensed plumbers through the town, and the work is inspected. The town posts a warning about fraudulent permit-fee emails and texts, so be careful with any message asking you to pay a fee. Questions about a specific job go to the plumbing inspector at Milford Town Hall.
Repiping is regulated work under the Massachusetts plumbing code (248 CMR), so the permit and the inspection are part of the standard process, not an extra.
What decides the price of repiping
We give you a clear written price before work starts. The factors are:
Insurance usually does not pay to replace pipes that are simply old or worn. It may cover resulting water damage from a sudden failure, so keep your plumber's written findings.

Repiping questions homeowners ask
If failures are isolated and the rest of the pipe is sound, repairs make sense. Several leaks in different places, rust-colored water and falling pressure across the house suggest the system is wearing out.
It depends on the size of the house and how accessible the walls are. Many jobs are done over several days, and phasing lets you keep part of the house usable.
No. Water is off for stretches of the work day and restored afterward. The plumber tells you ahead of time when it will be off.
Both are proven when installed correctly. PEX resists corrosion and freezing and goes in with less wall cutting. Copper tolerates heat and light and has a long track record. We help you choose based on the house.
Yes. Work on water supply piping is not minor repair under the state's consumer guidance, so a permit from the local inspector is required, and only a licensed plumber can pull it.
Milford Water Company adds corrosion control, which protects pipe over time. For specifics about your tap, look up the yearly Consumer Confidence Report from Milford Water Company, and test your own tap.

Before you decide
If you are not sure the whole house needs it, start with leak detection to find where water is escaping, since a single hidden leak is not the same as failing pipe. A line that has already split is covered under burst pipe repair. If the problem sits outside the house, the water service line page is the place to look. We also work in Holliston.
