Licensed Plumber Professionals Serving Nassau, NY

Masters Plumbing Service is a licensed, fully insured plumbing service operating across Nassau, NY. Our team consists of master plumbers and apprentices who carry active NY licenses and complete annual code-update training — because the plumbing code changes, and your contractor should know about it.

Our Nassau 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 Nassau 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.

When to Stop Waiting and Call a Plumber in Nassau

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

01

Slow Drains Throughout the House

A single slow drain is usually a localized clog. Multiple slow drains at once signal a main sewer line issue — the kind that backs up into your lowest fixtures if ignored.

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

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 Nassau 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

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.

Sewer & Drain Systems

Underground Sewer Repair — Camera, Lining & Excavation

Sewer line failures are the most consequential plumbing problem a property in Nassau, NY can face — and the most misdiagnosed. A sewer line that clears with a cable but backs up in 6 weeks isn't a clogging problem; it's a structural problem that clearing can't fix. Masters Plumbing Service's sewer crew runs a CCTV camera into every sewer line before recommending any repair so you see exactly what's there — and pay for exactly the repair that solves it.

  • CCTV pipeline camera inspection — distance-marked recorded footage
  • Hydro-jet drain clearing — 4,000 PSI nozzle rotating through the full pipe diameter
  • Root cutting — electric root cutter on sectional cable machine
  • CIPP trenchless pipe lining — no-dig structural repair for qualified pipe sections
  • Open-cut repair — precise camera-located excavation, code-compliant replacement
  • Manhole-to-manhole commercial sewer service
Commercial Plumbing

Nassau, NY Commercial & Industrial Plumbing

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 Nassau 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
  • Commercial restroom repair — all fixture types, ADA compliance awareness
  • Backflow preventer testing, certification, and replacement
  • Commercial water service — main repair, meter vault work, pressure testing
  • Scheduled maintenance contracts — monthly, quarterly, and annual programs

  • Acoustic detection — supply line failures located to within inches under slab or behind wall
  • Thermal imaging — moisture zone identification before any demo begins
  • Pressure decay testing — confirms active loss before detection begins
  • Slab leak repair — direct access, reroute above slab, or epoxy lining

The Masters Plumbing Service Difference — Across Every Plumber Call

Any plumber can say they're fast, honest, and affordable. Here's what actually separates Masters Plumbing Service from the field in Nassau, NY — concrete policies, not adjectives.

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.

Commercial Plumber in Nassau — Minimal Downtime

When plumbing fails at your commercial property in Nassau, every hour of downtime has a cost. Masters Plumbing Service's commercial plumbing response operates on the same 24/7 schedule as our residential service — because a restaurant's grease line backup at 6 PM on a Friday is just as urgent as a homeowner's burst pipe at midnight.

Our techs hold separate commercial crew certifications — different code requirements, different fixture types, and different service expectations than residential work in NY.

  • Commercial kitchen drain and grease trap service
  • Backflow preventer testing and annual certification
  • Commercial water heating — repair, replacement, and efficiency upgrades
  • Multi-family plumbing service — individual unit and common area systems
  • Commercial emergency response — 24/7 dispatch, priority routing

What Nassau, NY Customers Say About Masters Plumbing Service

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

★★★★★

"Arrived in 41 minutes on a Sunday night, diagnosed a burst supply line with a thermal camera, made a press-fit repair, and left the water running clean. Price matched the quote exactly."

— T. Morrison, Nassau
Nassau, NY · Emergency Plumbing
★★★★★

"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, Nassau
Nassau, NY · Sewer Line Service
★★★★★

"Water heater stopped producing hot water on a Friday evening. Masters Plumbing Service's tech arrived Saturday morning, diagnosed a failed thermocouple in 10 minutes, had the replacement on the truck, and installed it in under 45 minutes. Total cost was $175 — and he told me the price before touching anything. I've been burned by plumbers who find reasons to inflate the job. This was genuinely refreshing."

— S. Nakamura, Nassau
Nassau, 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, Nassau, NY
Nassau, NY · Leak Detection / Drain Service
★★★★★

"22-unit property manager here. Consistent response times, uniformed techs, flat-rate invoicing that makes budgeting predictable, and warranty callbacks honored immediately. Two years in, no complaints."

— Restaurant Owner, Nassau
Nassau, NY · Commercial Plumber
★★★★★

"Faint gas smell near the furnace. Masters Plumbing Service's certified gas plumber ran the detector over every fitting in the utility room, found a pinhole leak at a union fitting on the furnace supply — a fitting that had been vibrating loose over years of furnace cycling. Repaired the union, re-tested every connection, documented the manometer results. Exactly what a gas repair should look like — thorough and documented."

Plumber FAQ — Answers for Nassau, NY Homeowners

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

For emergency calls in Nassau, our dispatch target is 30–60 minutes from the moment we confirm your address and assign a technician. We stage technicians throughout Nassau — 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.
We don't have a limited "after-hours menu" — our emergency crews in Nassau 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.
We also background-check every technician before hire and re-screen annually. Your home and family's safety matters, and we staff accordingly.
We document warranty terms specifically because verbal warranties are unenforceable and lead to disputes. When you get a receipt from Masters Plumbing Service, the warranty terms are on that receipt — not implied, not "of course we'd come back" — actually written down.
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.
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.
Commercial plumbing service in Nassau, NY operates under the same 24/7 dispatch model as our residential service. We understand that a plumbing failure at a restaurant or retail property has immediate revenue implications, and we respond accordingly.
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.
Same-day water heater replacement is available in Nassau 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.
