Residential Repiping Services in amherst, NH

Galvanized steel pipe installed in homes built before the 1960s has a working life of roughly 40 to 50 years. Many houses in Amherst, NH are now well past that window, and the steel inside the walls has been quietly corroding from the inside out the entire time. When the inner diameter of a pipe narrows from rust buildup, water pressure drops, the water turns a brownish tint, and small pinhole leaks begin to show up behind drywall. Repiping is the process of replacing that aging pipe network with modern material, and it is one of the most valuable improvements you can make to an older home.

Why Homeowners in Amherst Choose to Repipe

Repiping is not a repair. It is a full replacement of the supply lines, and in some cases the drain lines, that run through your home. People usually come to us for one of a few reasons. The water pressure in the shower has dropped to a trickle. The water looks discolored first thing in the morning. Or a plumber has patched the same section of pipe three times in two years and the leaks keep coming back somewhere else.

At Paul the Plumber, we treat repiping as a long-term solution rather than a temporary fix. When corrosion has spread through a system, patching one leak simply moves the pressure to the next weak point. A full repipe removes the guesswork and gives you a fresh system engineered to last decades. We have been in business for 22 years, and in that time we have seen nearly every type of aging pipe a New Hampshire home can hold, from galvanized steel to early plastic to failing copper joints.

Common Situations That Call for a Repipe

Every home tells a different story, but certain scenarios come up again and again. Understanding which one matches your situation helps you make a confident decision.

  • Chronic pinhole leaks: When copper develops multiple small leaks over a short span, the metal itself is breaking down. Spot repairs will not stop the pattern.
  • Discolored or metallic-tasting water: Rust flaking from the inside of galvanized pipe shows up as brown or yellow water and leaves stains in sinks and tubs.
  • Weak water pressure throughout the house: Mineral and rust buildup narrows the pipe interior over time, choking the flow to fixtures.
  • Noisy pipes and frequent temperature swings: Restricted or failing lines make showers run hot then cold when another fixture is used.
  • A renovation or addition: If you are opening walls anyway, it is often the ideal time to replace outdated pipe while access is easy.

If any of these sound familiar, it is worth having the system inspected. We are happy to help you figure out whether a targeted repair or a complete repipe is the smarter investment for your home.

The Materials We Use and Why They Matter

Modern repiping typically relies on one of two materials: PEX or copper. Each has a place, and the right choice depends on your home, your water, and how you use it.

PEX is a cross-linked polyethylene tubing that has become the standard for residential repiping. It is flexible, which means fewer joints and fewer potential leak points. It resists the scale buildup that plagues metal pipe, it tolerates freezing better than rigid pipe because it can expand slightly, and it installs faster with less demolition. For most homes in Amherst, PEX offers the best balance of durability, performance, and value.

Copper remains an excellent material with a long track record. It handles high temperatures well, it is naturally resistant to bacteria, and many homeowners prefer it for its proven longevity. The trade-off is cost and labor, since copper requires soldered joints and more careful routing. During your consultation, we walk you through both options and explain the technical differences in plain language so you can decide what fits your priorities. There is no sales pressure, just honest guidance from a team that treats customers like family.

How Our Repiping Process Works

A whole-home repipe sounds disruptive, and without a plan it can be. Our job is to make the process orderly, predictable, and as clean as possible. Here is how we approach it.

First, we inspect the existing system. We map where the pipes run, identify the material, check the water pressure, and look for the points where corrosion or leaks have taken hold. This gives us a complete picture before we open a single wall. We then provide up front pricing, so you know the full scope and cost before any work begins. There are no surprise charges added at the end.

Next comes the access and layout phase. We plan the most efficient routing for the new lines, which keeps wall openings to a minimum. We protect floors and furnishings, shut off the water, and begin running the new pipe. Because we route carefully, we often reduce the number of connections compared to the original system, which lowers the long-term chance of leaks.

After the new lines are in place, we pressure-test the entire system to verify there are no leaks anywhere. Only once the system passes do we reconnect fixtures, restore water service, and begin the patch and cleanup process. We leave the work area neat and walk you through everything we did before we go. All of our technicians are licensed and background checked, so you can feel comfortable with the people in your home from start to finish.

That warranty is our promise that the repipe we install is built to perform for the long haul, not just until the next service call.

I’ve used Paul the Plumber twice now for electrical issues and they have been wonderful each time. They are fast, polite, knowledgeable, and very fairly priced.

V. Vincze

We had an issue with our water…too hard, calcium deposits, and very little pressure in our master bathroom shower only. The techs (Mike E. & Tyler S.) arrived right on time. They were friendly and very personable. After installing our whole house filtration system and successfully finding the issue with our master bathroom, they left the work areas in pristine condition. They were meticulous in their work, and I highly recommend them for any plumbing needs!

D. Marchand

I cannot say enough about this company!!! Their only concern is that you are up and running again with no worries. I’ve had Kyle the plumber, and Josh their electrician out here and both are polite, well trained and you can tell they truly care about getting you back in service. Great service, well trained caring staff! I will never go anywhere else!

H. MacPherson

I would recommend Paul the Plumber 100%. They offered same/next day service. They were friendly, professional and quick – from the office staff to the technicians. Overall an amazing experience from start to finish.

K. MacCallum

First time customer, and am very pleased with the whole experience. The highlight was definitely with the technicians assigned to the job and their work – Tyree and Corey were clean, polite, well-informed, and very helpful with some of the questions I had along the way. Their work appears to be top-notch, and they made sure no mess was left behind. Will definitely be calling and requesting these two again on any future needs.

T. Minasian

These are the after photos of the Rinnai tankless water heater installation and vent to the outside. It was important to me that the crew was able to use the existing vent hole to the outside to run both the intake vent pipe and the outside vent pipe. It made the job very clean and did not change the appearance of the outside wall. A shout out to Mike E, Caleb, Josh & Corey

W. Chepren

I made an appointment on line the morning of July 31 and two trucks showed up at 1:00 pm right on time that same afternoon. Both guys were friendly and very knowledgeable. They quickly found the source of the wet patch on my ceiling which wasn’t the plumbing but a problem with the shower curtain. This is the second time I have called Paul. Both times I got outstanding service and will always call on Paul the Plumber for any plumbing problems in the future. Very reasonable cost for the visit.

D. Lefort

Arrived as scheduled to fix a leak from the shower valve. Tried to fix old 30 or 40 year old unit but had to replace with a new one. Quality work, parts and cleaned up when they were done. Would definitely use again.

S. DesMarais

Josh was amazing. He was able to install my ring doorbells with no issues. He also did a great check of my homes smoke detectors and a few electrical plugs. He was thorough, Knowledgeable, and easy to work with. I would definitely use them again.

K. Bernardo

We’re first time home owners and needed help with some plumbing and adding a filter system. They were able to get a technician scheduled to our house within a day or so of me contacting them. Mike was super helpful and was able to complete all the jobs in a timely manner, and also cleaned up the areas he was working in. Overall a great experience and would definitely use them for future jobs.

J. Wojo

DJ from PTP was incredibly helpful and knowledgeable. My shower was not draining and it became a bigger project than I thought it would and they came out quickly and were able to fix my problem. Then when my water heater had a slow leak they came back out quickly to attend to it and fix my problem. I really appreciate their hard work. Thank you so much!! Would definitely recommend them.

D. Weaver

What a fantastic business. Helped us work with our water district in resolving meter replacement issues. They also fixed a pipe leak that had developed over time. Caleb was wonderful and answered our questions as well as working with the water district engineer on the meter issues. So easy to work with.
