TESTIMONIALS

Why Homeowners in Londonderry, NH Trust Us

Our tankless water heater stopped working right before Christmas leaving us with not only no hot water, but not even water to do laundry or run the dish washer.

So finding a good plumber, you can rely on, is different than finding a good plumber. When my family needed a plumber recently, LHR handled our call.

LHR got my service scheduled immediately for 2 days out from the day I called. Cody, the technician, showed up on time and was professional.

This is a completely professional organization start-to-finish. From my first phone call through the service to the follow-up, the LHR team treated me with kindness.

Cold call (literally!) from Hot Water Heater Manufacturer website. No prior relationship with them. No problem. Came same day. Tech friendly and knowledgeable.

Plumber in Londonderry, NH

Londonderry went from orchard country to one of the area’s busiest suburbs in just a few decades, and its homes show that growth. A handful of old farmhouses still stand near the town common and along the original farm roads. Most of town, though, is made up of colonials, capes, and split-levels built from the 1970s through the 90s, and their original copper lines, fixtures, and water heaters are now wearing out. Newer developments have modern plumbing, but even those first water heaters don’t last forever.

LHR Plumbing and Heating works on all of these homes. See our residential plumbing services to learn how we help Londonderry families.

Plumbing Repair & Troubleshooting

So many Londonderry homes were built around the same time that their plumbing tends to fail around the same time too, and cold winters only speed it up. Here is what we fix most often.

Frozen lines show up in bathrooms over garages and kitchens on north-facing walls.
Hidden leaks from aging copper can leave stains on finished basement ceilings.
Slow or backed-up drains build up in lines that have been in use for 30 years or more.
Failing water heaters in homes from the 80s and 90s start leaking or losing heat.
Aging pipes develop pinholes and corrosion, especially where water is hard.

We repair the cause, not just the symptom, and test everything before we leave your home.

Water Heater Installations & Upgrades

Plenty of Londonderry homes still have the type of tank that came with the house. We can replace a failing unit with one sized for your family or upgrade you to a tankless water heater for steady hot water and more room in the basement. Financing can make the switch easier.

Planning something bigger? If you are finishing a basement or adding an in-law suite, we can plan the plumbing and hot water for the whole house. Every job is done to current code.

A Recent Plumbing Job in Londonderry, NH

Amanda noticed a brown stain spreading across her finished basement ceiling in her 1980s colonial off Mammoth Road. Our plumber used leak detection tools to pinpoint a pinhole leak in a copper line and opened just one small section to repair it. Amanda said she was relieved the fix was quick and the patch was barely noticeable.

Frequently Asked Questions

Should I worry about copper pipes in my 1980s Londonderry home?

After 30 or 40 years, copper can develop pinhole leaks, especially with hard water. Look for small stains, green spots on pipes, or damp areas. A plumber can check the condition and recommend repairs or replacement.

What signs point to a bigger plumbing problem?

Recurring clogs, a sudden drop in water pressure, ceiling stains, or a musty smell in the basement are warning signs. These usually mean the issue is hidden and growing.

Do I need a permit for plumbing work in Londonderry?

Larger jobs like water heater replacements, new fixtures, or moving pipes usually need a permit from the Town of Londonderry. Basic repairs typically don’t. We will let you know up front if yours does.

How do I keep pipes over my garage from freezing in a Londonderry winter?

Keep the garage door closed, add insulation where you can, and let faucets drip on the coldest nights. If a pipe still freezes, our frozen lines service thaws it safely and checks for cracks.

Do you offer emergency plumbing in Londonderry?

Yes. Londonderry is right next to our Manchester location, so we can reach you quickly. Give us a call and we will get a plumber on the way.
