Who We Are

Licensed Water Line Repair Professionals Serving Portsmouth, NH

We started Masters Plumbing Service with a simple belief: plumbing customers in Portsmouth, NH deserve honest information, upfront pricing, and a technician who actually shows up in the window they promised. That sounds basic. In this industry, it's rarer than it should be.

When you call Masters Plumbing Service for Water Line Repair in Portsmouth, a live dispatcher — not an answering service — takes your call, determines the urgency, and assigns the nearest available licensed technician to your address. From clogged drains to full sewer line collapses, from a dripping kitchen faucet to a water heater that's flooding your utility room, our crews are trained and equipped to handle it on the first visit in most cases.

We are fully licensed in NH, carry general liability insurance and workers' compensation coverage on every technician, and we permit work that requires it. That last part matters more than it sounds: an unpermitted plumbing repair can void your homeowner's insurance coverage for related water damage, and it can complicate a home sale. We pull permits, schedule inspections, and close them out correctly.

Warning Signs

7 Signs You Need a Licensed Water Line Repair in Portsmouth, NH

Most plumbing problems give warning signs before they become expensive disasters. Here's what Portsmouth homeowners should watch for — and why waiting makes every one of them worse.

01

Slow Drains Throughout the House

When two or more drains run slow simultaneously in your Portsmouth home, the blockage is almost always in the main line, not individual fixture traps.

02

Water Bill Spike With No Explanation

A sudden 20–40% increase in your water bill with no change in usage habits often means a supply line leak inside the structure or underground — invisible but actively running.

03

Discolored or Rusty Hot Water

Rusty hot water in Portsmouth, NH homes typically means the water heater is past mid-life and the tank lining has begun corroding. Anode rod replacement may buy time; tank inspection tells you how much.

04

Low Water Pressure at Multiple Fixtures

If your Portsmouth home's water pressure has dropped noticeably across the whole house, the issue is upstream — likely the PRV (pressure reducing valve), the main supply line, or corroded galvanized pipe narrowing the interior.

05

Running Toilet That Won't Stop

The sound of water running in the tank between flushes is a flapper or fill valve issue. Neither is expensive to fix, but both compound into significant water costs if ignored.

06

Wet Spots or Stains on Ceilings and Walls

Active in-wall leaks in Portsmouth, NH homes create conditions for mold growth within 24–48 hours of sustained saturation. Locating and repairing the leak quickly limits both structural damage and remediation scope.

07

Gurgling Sounds in Drains or Toilets

Gurgling when a toilet is flushed, or when the washing machine drains, points to a venting issue or a partial main line blockage. Air displaced by water flow has nowhere to go and creates the gurgling sound.

Leak Detection & Pipe Repair

Pipe Repair & Repiping in Portsmouth

Once located, our pipe repair techs use the method appropriate to the pipe type — press-fit or sweated copper, PEX expansion fittings, galvanized replacement, or slab leak rerouting — and pressure-test every repair before leaving.

Acoustic detection — supply line failures located to within inches under slab or behind wall

Gas Line Services

Gas Line Repair & Installation in Portsmouth, NH

Gas line work belongs in a short list of plumbing tasks where there is truly no acceptable shortcut. A fitting that isn't fully engaged, a connector bent during installation, or a repair that skips the post-work manometer pressure test can produce a leak that's invisible, odorless (without the added odorant), and dangerous. Masters Plumbing Service's certified gas plumbers in Portsmouth, NH carry combustible gas detectors to every job and conduct a timed manometer pressure hold test on every repaired or installed segment before restoring gas to the line.

Gas leak service — detector survey, isolation, repair, documented re-test
Gas appliance connections — range, dryer, fireplace, water heater, generator
New gas installation — outdoor kitchen, generator, pool heater, BBQ
CSST service — bonding conductor installation per current code
Pressure test and permit closeout — required documentation provided

Customer Reviews

Real Reviews From Portsmouth Homeowners

Read what Portsmouth, NH customers say about our response times, our technicians, and our pricing transparency.

★★★★★

"Called Masters Plumbing Service at 1:30 AM — burst pipe, water spreading across the kitchen floor. I expected to wait until morning or pay triple time. The dispatcher was calm, professional, and had someone at my door in under 50 minutes. Repair was completed by 3 AM, the tech left the area dry, and I had hot water by breakfast. Exceptional emergency service."

★★★★★

"Called three companies before Masters Plumbing Service. The first two couldn't come until morning; the third gave no price cap. Masters Plumbing Service quoted flat-rate, arrived in 55 minutes, cleared a root intrusion, and scoped the line."

— R. & C. Vásquez, Portsmouth

Portsmouth, NH · Sewer Line Service

★★★★★

"Gas water heater out on Friday evening — tech arrived Saturday morning, diagnosed a failed thermocouple in 10 minutes, replaced it in under 45 minutes total. Price was $175, exactly as quoted."

— B. Harrington, Portsmouth

Portsmouth, NH · Water Heater Repair

★★★★★

"My water bill jumped from $90 to $160 in one month with no change in usage. Masters Plumbing Service ran a pressure decay test, found a 6% pressure loss on the hot side, deployed the acoustic detector on the slab in the utility room, and located the leak at a copper elbow under the slab — 4.5 feet from the wall. They presented three repair options with pricing, I chose the reroute through the wall framing, and the new line has been zero-issue for five months. The detection appointment saved me from speculative demolition."

— L. & G. Abramowitz, Portsmouth

Portsmouth, NH · Leak Detection / Drain Service

★★★★★

"As a property manager overseeing 22 units, I need a plumbing contractor who shows up, does the work correctly, and doesn't pad the bill. Masters Plumbing Service has been our go-to for two years. Response times are consistent, the techs are uniformed and professional, and the flat-rate invoicing makes budgeting predictable. We've never had a warranty callback that wasn't honored immediately."

— Property Manager, Portsmouth

Portsmouth, NH · Commercial Water Line Repair

★★★★★

"Faint gas smell in the utility room. Tech ran the detector over every fitting, found a micro-leak at a union fitting that had vibrated loose over years of furnace cycling. Repaired, detector-tested every connection, manometer documented."

FAQ

Water Line Repair FAQ — Answers for Portsmouth, NH Homeowners

These are the actual questions our dispatchers and technicians answer every day in Portsmouth, NH.

For emergency calls in Portsmouth, our dispatch target is 30–60 minutes from the moment we confirm your address and assign a technician. We stage technicians throughout Portsmouth — not at a single central shop — which keeps our actual drive times short. Non-emergency scheduled calls are booked in specific time windows so you're not clearing your whole day for a "sometime between 8 AM and 5 PM" appointment.

Flat-rate pricing means we price the outcome, not the hours. We've invested in technician training and truck stocking so we can work efficiently — and pass that efficiency to customers through competitive flat rates rather than inflating an hourly clock.

Masters Plumbing Service's emergency dispatch in Portsmouth, NH is available around the clock, 365 days a year. The emergency services we handle after hours in Portsmouth include: burst and ruptured pipe repair, active sewer backups, water heater failure (gas and electric), major drain blockages affecting multiple fixtures, gas line leaks (after utility shutoff), frozen pipe response, and main water line failures.

We also background-check every technician before hire and re-screen annually. Your home and family's safety matters, and we staff accordingly.

Yes. Every repair and installation performed by Masters Plumbing Service in Portsmouth, NH carries a written workmanship warranty — the specific term and scope are documented on your service receipt. Parts warranties from the manufacturer apply in addition to our workmanship coverage. If a covered repair fails within the warranty period, you call us and we return to fix it at no charge.

Our dispatcher will walk you through protective steps for your specific situation when you call. That's part of why we answer live — not just to take your information, but to help you prevent additional damage while our technician drives to you.

If the meter test confirms water loss, call us before opening any walls. Our acoustic and thermal detection equipment locates leaks to within inches in most cases — which means a small, targeted access opening instead of a speculative wall demolition.

Yes. Masters Plumbing Service serves both residential homeowners and commercial property owners, managers, and operators throughout Portsmouth, NH. Our commercial team handles restaurant drain and grease trap service, office building fixture repair, multi-unit residential systems, backflow preventer testing and certification, commercial water heater service, and after-hours emergency response for business properties.

Often, yes — if a CCTV camera scope confirms the pipe is a candidate for trenchless CIPP (cured-in-place pipe) lining. Trenchless lining installs a structural epoxy sleeve inside the existing pipe from an access point — no trenching over the pipe run. It's effective for cracked pipes, root-infiltrated joints, and minor deformation as long as the host pipe retains enough structural integrity to hold the liner during the curing process.

Masters Plumbing Service handles the full range of water heater services in Portsmouth, NH: diagnosis and repair for gas and electric tank units (thermocouple, pilot assembly, gas valve, heating elements, thermostats, T&P valve, anode rod); tankless water heater repair including igniter assemblies, flow sensors, heat exchanger descaling, and error code diagnosis; and full replacement for units beyond economic repair, including conversion from tank to tankless where the infrastructure supports it.

Plumbing costs in Portsmouth, NH vary significantly based on the type of repair, pipe material, access conditions, and parts required. Rather than give you a range that's too wide to be useful, Masters Plumbing Service provides a flat-rate quote after on-site diagnosis — before any work starts. That quote is accurate because we've seen the specific failure, not estimated based on a description.

Pulling permits matters beyond legal compliance: an unpermitted plumbing repair can void homeowner's insurance coverage for related water damage and can create title issues when selling the property. We handle permit procurement and inspection coordination as part of the job — permit costs are disclosed in your flat-rate quote.
