Trusted Repiping Experts Serving Durham, NH

Galvanized steel pipe installed in the mid-20th century has a service life of roughly 40 to 50 years. Many homes in Durham, NH are now well past that mark, which means the supply lines hidden behind walls and under floors are quietly corroding from the inside out. When that corrosion reaches a certain point, no amount of patching will restore the pipe. The only lasting fix is repiping, the process of replacing the aging distribution system with new piping. This is the work we do, and we want to explain exactly what it involves so you can make an informed decision for your home.

What Repiping Actually Means for Your Home

Repiping is the replacement of the water supply pipes that carry fresh water throughout your house. In older Durham homes, these lines are often galvanized steel, a material that rusts and scales on the interior over decades. As the rust builds up, the inside diameter of the pipe shrinks. Water pressure drops, flow becomes uneven, and the water itself can take on a brown or yellow tint. Repiping removes these failing pipes entirely and installs new ones that restore full flow and clean water.

There is an important distinction between a repair and a repipe. A repair addresses one failure point, a single leak or a single corroded joint. A repipe addresses the whole system at once. When we see repeated leaks in different parts of a home, discolored water from multiple fixtures, or chronic low pressure that no single repair resolves, those are signs the problem is systemic. Repiping treats the root cause rather than chasing symptoms year after year. For a home that has already needed two or three pipe repairs in a short span, a full repipe is often the more economical path over time.

Materials We Use and Why They Matter

The piping material we install has a direct effect on durability, water quality, and how your system behaves over the coming decades. We select materials based on your home’s layout, your water chemistry, and the specific application, whether that is a hot line, a cold line, or a main supply run. Each option has distinct technical characteristics.

  • PEX cross-linked polyethylene: A flexible tubing that resists scale and corrosion, handles freezing stress far better than rigid pipe, and requires fewer fittings because it bends around corners. This reduces the number of potential leak points.
  • Copper: A rigid metal pipe with a long track record, naturally resistant to bacteria, and rated for high temperatures. Type L copper is a common choice for supply lines where durability is the priority.
  • CPVC chlorinated polyvinyl chloride: A rigid plastic pipe rated for both hot and cold water that offers good corrosion resistance and a smooth interior that resists scale buildup.

When we walk through your home before a repipe, we assess which material fits best. A house with hard water that tends to scale might benefit from the smooth interior of PEX. A homeowner who prefers a material with a multi-decade history might lean toward copper. We explain the trade-offs clearly, including temperature ratings, pressure ratings, and expected service life, so the choice reflects your priorities and not a one-size-fits-all approach.

Our Repiping Process from Start to Finish

A repipe is a significant project, and we approach it with a methodical sequence designed to limit disruption to your household. The work is not simply ripping out old pipe and dropping in new. It involves careful planning, precise access, and thorough testing before anything is closed back up.

  1. Assessment and mapping: We inspect the existing system, identify the routing of supply lines, note the location of every fixture, and document pressure readings and water quality issues.
  2. Protection and access: We cover floors and furnishings, then open only the wall and ceiling sections needed to reach the pipe runs. We plan access points to minimize the number of openings.
  3. Installation of new lines: We route the new piping, secure it correctly to prevent movement and noise, and connect each fixture, including sinks, tubs, showers, toilets, and water-using appliances.
  4. Pressure testing: Before closing any wall, we pressurize the new system and verify there are no leaks at any joint or connection.
  5. Restoration and cleanup: We patch the openings we made, restore the surfaces, and leave the work areas clean.

Throughout the project we keep you informed. You will know what we are doing, why we are doing it, and roughly how long each stage takes. We also restore water service as quickly as practical during the work so your household is not left without running water any longer than necessary.

Signs Your Durham Home May Need Repiping

Many homeowners live with symptoms of failing pipes without realizing those symptoms point to a larger issue. Recognizing the warning signs early lets you plan a repipe on your own schedule rather than reacting to an emergency burst line. Discolored water, especially rust-tinted water from the first draw in the morning, often indicates interior corrosion in galvanized lines. A steady decline in water pressure across the whole house, rather than at a single faucet, suggests the pipe interiors are narrowing.

Other indicators include frequent leaks at different points, visible corrosion or flaking on exposed pipe, a metallic taste in the water, and pipes that are simply old enough to be near the end of their rated life. If your home was built before modern plastic and copper became standard and still has its original supply lines, an inspection is worthwhile. We are happy to help you understand the condition of your system and whether repiping makes sense now or can be planned for later.

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

Michele

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. They explain everything well and answer my questions thoroughly and I feel safer now knowing what was causing my electrical issues and having it fixed! I will be using Paul the Plumber for all my household needs going forward

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.

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.

S. Baraket

Never used Paul The plumber company before but I’m glad I did. Very courteous, professional and pleasant from the answering service (Diane) to employees (Jeremy). They diagnosed the problem and fixed it in no time. Very happy and satisfied with their service. Definitely will use again. Thank you

J. Shea

John was wonderful. He found the problem right away and fixed it. He checked other outlets just to make sure I would be safe. He explained different programs the company offers also. I’m very happy.

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.

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. 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.

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.

Great service, well trained caring staff! I will never go anywhere else!

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.
