Who We Are
Licensed Water Heater Replacement Professionals Serving Exeter, NH
We started Masters Plumbing Service with a simple belief: plumbing customers in Exeter, 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.
Our Exeter service hub keeps technicians staged throughout the area so we're not driving 45 minutes to your house while a burst pipe runs unchecked. Fast arrival isn't a slogan for us — it's a logistical commitment backed by how we staff and deploy our crews.
Every Masters Plumbing Service technician working in Exeter is background-checked before hire, uniformed, and arrives in a marked vehicle. You know who's coming and you can verify their credentials. That's the standard we hold ourselves to — not because it's legally required, but because it's what we'd want if we were the customer.

Warning Signs
When to Stop Waiting and Call a Plumber in Exeter
Your plumbing system tells you when something is wrong. The challenge is recognizing the signals before a small repair becomes a major remediation project.
01
Slow Drains Throughout the House
When two or more drains run slow simultaneously in your Exeter home, the blockage is almost always in the main line, not individual fixture traps.
02
Water Bill Spike With No Explanation
Hidden supply line leaks in Exeter homes waste thousands of gallons before they surface. A meter check with all fixtures off confirms whether water is escaping.
03
Discolored or Rusty Hot Water
Brown or rust-colored hot water is almost always a water heater with a depleted anode rod or internal corrosion — both signs the unit is approaching failure.
04
Low Water Pressure at Multiple Fixtures
If your Exeter 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
A toilet that runs constantly wastes 26–200 gallons per day depending on severity. That's $15–$100 per month per toilet — for a repair that typically costs far less than one billing cycle of waste.
06
Wet Spots or Stains on Ceilings and Walls
Active in-wall leaks in Exeter, 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
In Exeter, gurgling drains — especially when a different fixture is used — are one of the earliest and most reliable signs of a developing main sewer line blockage.
Water Heater Replacement Solutions — Emergency, Residential & Commercial
Here's a look at what our Exeter, NH-licensed plumbers do every day — and why the depth of our service offering means you call one company instead of tracking down three.
Emergency Response
Emergency Water Heater Replacement — Exeter Response Team

Commercial Plumbing
Commercial Water Heater Replacement in Exeter, NH — Multi-Site & After-Hours
Commercial plumbing problems affect more than one household — they affect your customers, your employees, and your operating hours. A backed-up restroom in a restaurant means health code issues. A broken water line in a retail space means temporary closure. Masters Plumbing Service responds to commercial plumbing calls in Exeter with the same 24/7 commitment and the same licensed technicians as our residential service — because your business hours aren't our business hours.
Grease trap cleaning and documentation for health code compliance
Multi-fixture restroom service — clogs, valve replacement, partition replacement
Water main and service line repair for commercial properties
Preventive maintenance programs — inspection, drain cleaning, water heater service
Leak Detection & Pipe Repair
Hidden Leak Detection in Exeter, NH — Non-Invasive
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
Thermal infrared camera scanning — moisture mapping without wall cuts
Pressure testing — zones isolated to identify the failing branch
Slab leak repair — direct access, reroute above slab, or epoxy lining
Repipe service — whole-house scope, phased access, pressure-tested final system
Gas Line Services
NH-Certified Gas Line Work — Safe & Tested
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 Exeter, 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 detection — combustible gas detector at every connection
Appliance gas hookup — flex connector, shutoff valve, post-connection pressure test
New gas line runs — BTU-load sized, black iron or CSST
CSST service — bonding conductor installation per current code
Pressure test and permit closeout — required documentation provided
Our Process
From Your Call to a Fixed Plumbing System — 4 Steps
This is the sequence every Exeter service call follows. We built it to eliminate the three things customers hate most: waiting, uncertainty, and surprise costs.
1
Live Dispatcher Answers
A real person answers your call, takes your address and describes the situation, classifies urgency, and assigns a technician. You receive a confirmation text with the tech's name and ETA.
2
Licensed Tech Arrives Fast
Our local dispatch model keeps technicians staged throughout Exeter so we're measuring drive time in minutes, not hours.
3
Diagnosis & Flat-Rate Quote
The technician diagnoses the problem — using test equipment, not guesswork — and presents you with a written flat-rate quote before any work begins. You approve the price, then we work.
4
Repair Completed & Warranted
Approved repairs happen immediately — we don't schedule a follow-up for a standard service call. When we leave, the system is functional and the repair carries our written workmanship warranty.
🛡️
The Masters Plumbing Service Guarantee for Exeter Customers

Flat-Rate Pricing Always
Time-and-material billing rewards slow work. Flat-rate pricing aligns our incentive with yours: finish the job correctly and efficiently. Our rates are priced to be fair, not padded for contingency.
🔧
Stocked Trucks, One-Visit Fixes

🪪
Licensed & Verified Every Time
You're not taking our word for it — you can look up every tech's license on the NH licensing board website. We encourage it.
📞
Live Humans Answer the Phone
24/7 live answer means emergency calls reach a decision-maker instantly, not an answering service that relays a message at 8 AM.
🛡️
Written Warranty on Every Job

★★★★★
"1:30 AM call for a burst pipe — they arrived in under 50 minutes, completed the repair by 3 AM, and the invoice matched the upfront quote. No surprises."

★★★★★
"Had a main sewer line backup on the night before Thanksgiving. Masters Plumbing Service dispatched within the hour, cleared a grease-and-root blockage in the main line, and scoped it with a camera after clearing. The tech explained what he found, showed me the camera footage, and noted a joint offset at 62 feet we should watch. Transparent, fast, and fairly priced."
— R. & C. Vásquez, Exeter
Exeter, NH · Sewer Line Service
★★★★★
"Intermittent hot water for weeks before it stopped entirely. The tech traced it to a failing gas control valve, replaced it with a unit from the truck, and tested through a full heat cycle. Done in under an hour."
— S. Nakamura, Exeter
Exeter, 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."
— F. Okonkwo, Exeter, NH

"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 Heater Replacement FAQ — Answers for Exeter, NH Homeowners
Real questions, honest answers. Here's what people in Exeter ask us before scheduling service — and what they should know.
Our emergency response target in Exeter is under 60 minutes, but the realistic range depends on time of day, traffic conditions, and current call volume. We give you an honest ETA at dispatch — not the best-case number that looks good on a website.
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.
We don't have a limited "after-hours menu" — our emergency crews in Exeter carry the same equipment and parts as daytime crews and handle the full scope of plumbing failures at 2 AM the same way we do at 2 PM.
Every technician Masters Plumbing Service dispatches in NH holds an active state plumbing license. Masters Plumbing Service carries general liability insurance and workers' compensation coverage on all field personnel. We can provide license numbers and a certificate of insurance on request — and we encourage you to verify licenses with the NH licensing board before any plumber begins work on your property, regardless of which company you hire.
Yes. Every repair and installation performed by Masters Plumbing Service in Exeter, 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.
For active water leaks: locate your main water shutoff valve (typically at the meter, in the utility room, or under an exterior wall) and close it clockwise until it stops. Move valuables off wet floors. Don't use electrical outlets near standing water. For sewer backups: stop using all drains and toilets immediately — continued use worsens the backup. For gas smells: leave the building, don't operate any switches, and call your utility company's emergency line from outside first.
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 Exeter, 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 Exeter, 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 Exeter, 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.
