Who We Are

Masters Plumbing Service — Locust Valley, NY's Local Plumber Experts

We started Masters Plumbing Service with a simple belief: plumbing customers in Locust Valley, NY 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 Locust Valley 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.

We are fully licensed in NY, 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 Plumber in Locust Valley, NY

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 Locust Valley 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 Locust Valley 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

Rusty hot water in Locust Valley, NY 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 Locust Valley 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

Moisture stains on ceilings or walls that reappear after painting point to an active supply or drain line leak inside the structure. The visible damage is usually much smaller than the wet zone inside the wall.

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.

Plumber Reviews — How We Handle It in Locust Valley, NY

Read what Locust Valley, NY customers say about our response times, our technicians, and our pricing transparency.

★★★★★

"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."

— T. Morrison, Locust Valley
Locust Valley, NY · Emergency Plumbing
★★★★★

"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, Locust Valley
Locust Valley, NY · Sewer Line Service
★★★★★

"Gas water heater wasn't lighting. Masters Plumbing Service came out same day, tested the thermocouple output with a meter, confirmed it was reading 8mV when the gas valve needs at least 25mV to stay open, and replaced the thermocouple and pilot assembly. Done in under an hour, came in exactly at the quoted price. Very professional — would call again without hesitation."

— S. Nakamura, Locust Valley
Locust Valley, NY · Water Heater Repair
★★★★★

"Three slow drains and a gurgling toilet when the washer ran. CCTV scope found root intrusion at two clay tile joints and a grease plug at 28 feet. Hydro-jetted and re-scoped to confirm. System running clean four months later."

— F. Okonkwo, Locust Valley, NY
Locust Valley, NY · 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."

— Restaurant Owner, Locust Valley
Locust Valley, NY · Commercial Plumber
★★★★★

"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

Plumber FAQ — Answers for Locust Valley, NY Homeowners

Real questions, honest answers. Here's what people in Locust Valley ask us before scheduling service — and what they should know.

Our emergency response target in Locust Valley 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.
Masters Plumbing Service's emergency dispatch in Locust Valley, NY is available around the clock, 365 days a year. The emergency services we handle after hours in Locust Valley 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.
Every technician Masters Plumbing Service dispatches in NY 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 NY 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 Locust Valley, NY 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.
The quickest self-check: shut off every fixture and appliance in the house (including ice maker lines and irrigation if connected), then watch your water meter for 15 minutes with nothing running. If the meter dial or leak indicator is moving, water is escaping the supply system somewhere. Other indicators include an unexplained increase in monthly water usage, ceiling stains that recur after painting, soft spots in flooring, mold odor without visible source, or the sound of running water inside walls with all fixtures off.
Yes. Masters Plumbing Service serves both residential homeowners and commercial property owners, managers, and operators throughout Locust Valley, NY. 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.
Cases where excavation is required: fully collapsed pipe sections, severe pipe belly (negative grade that holds sewage), and pipe offset too severe for lining to bridge. We scope before recommending anything and show you the camera footage so you can see which category your pipe falls into.
Same-day water heater replacement is available in Locust Valley for the most common residential tank sizes — our trucks carry 40 and 50-gallon gas and electric units. If your unit is gone and you need hot water today, call us.
Common residential repairs — fill valve replacement, flapper, faucet cartridge, drain clearing — are typically in the $100–$300 range. More complex work like slab leak repair, sewer line lining, or water heater replacement varies by scope and we walk you through the numbers on-site. No work begins until you've approved a written price.
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.
