From routine maintenance to full emergency response, Masters Plumbing Service dispatches trained plumbing specialists from inside Andover to arrive in the shortest possible window with the tools already loaded.
Masters Plumbing Service started because too many Andover residents were getting hit with bait-and-switch pricing from out-of-area contractors. Our founders built this company on one promise: every technician who walks through your door carries their MA plumbing license, a fully stocked service van, and the authority to quote a fixed price on the spot — before touching a single pipe.
We handle everything from 3/4-inch copper repiping to tankless water heater swaps to high-pressure hydro-jetting on grease-clogged commercial lines. That scope is intentional — it means one call to +1-855-718-1500 gets you a tech qualified for the actual job, not a referral chain that burns your afternoon.
All field plumbers hold active MA plumbing credentials and the company carries general liability plus workers' comp.
Our Andover dispatch center takes live calls every hour of every day — including holidays.
Each van leaves our Andover yard pre-loaded with copper, PVC, PEX, press fittings, and common repair assemblies so we fix it on the first visit.
No hourly mystery charges. You approve the price before any wrench turns.
Most plumbing failures in Andover homes give advance warning. The ones that cost homeowners the most are the ones where those signals got ignored for one season too long.
Slow or gurgling drains throughout multiple fixtures — often signals a partial blockage or root intrusion in the main sewer line, not just a single clog.
Noticeably lower water pressure — in Andover homes with aging galvanized or copper supply lines, dropping pressure usually means scale buildup or a hidden leak upstream.
Water heater rumbling or popping sounds — sediment has layered on the tank bottom and is reducing efficiency; ignoring it accelerates tank failure.
Sewer odors inside the home — a dried P-trap or a cracked vent pipe is the typical culprit; both need professional inspection before they become a health issue.
Unexplained spike in your water bill — even a small pinhole slab leak wastes thousands of gallons monthly. If your bill jumped without a usage change, call us.
Discolored or foul-tasting tap water — corroded supply pipes or a failing water heater anode rod can introduce rust or sulfur into the line.}
Visible moisture or staining under sinks or along baseboards — even slow seeps rot subfloor material and invite mold growth quickly in humid Andover, MA conditions.
Running toilets that won't stop — a worn flapper or fill valve wastes roughly 200 gallons per day and is a 10-minute fix for our Andover technicians.
From slab leak detection to full commercial repiping, our Andover-based plumbers bring the right equipment and the right credentials to every job category below.
A ruptured supply line or a sewage backup doesn't wait for business hours. Our Andover emergency dispatch routes the nearest available licensed tech to your address, usually within the hour, with shutoff tools, wet-vac equipment, and common repair assemblies already aboard.
Residential Plumbing in Andover covers a wide band of complexity — from a faulty toilet fill valve to a complete PEX repipe of a 1960s home with failing galvanized lines. Our licensed techs assess the actual condition of your supply and drain system, quote the repair honestly, and complete it with materials rated for Andover, MA building code.
Grease trap maintenance, backflow preventer testing, and high-capacity water heater installation are recurring service categories for our Andover commercial accounts — work that demands a contractor with the right insurance and the right permits.
A cold shower is an inconvenience. A failing water heater that floods a utility room is a structural problem. Our Andover water heater techs service all major brands in both 40- and 50-gallon tank configurations as well as on-demand tankless units from Rinnai, Navien, Rheem, and Bradford White. We flush sediment, replace anodes, repair pressure relief valves, and — when the unit is past its service life — install a new one the same day in most cases.
A drain snake clears soft clogs. Roots, grease buildup, and scale require 4,000 PSI hydro-jetting that scours the pipe wall clean — and a camera inspection confirms the result. Our Andover drain crews run RIDGID SeeSnake camera systems through sewer lines before and after cleaning so you see exactly what was there and what's gone.
Most slab leaks in Andover, MA properties involve copper lines that have corroded at a soil contact point. We offer in-slab direct repair, epoxy pipe lining, or full rerouting above the slab, depending on the pipe's overall condition.
These aren't marketing slogans — they're operational commitments our dispatch and field teams are held to on every call.
Hourly billing on plumbing work is a mechanism for runaway invoices. We quote the job, not the clock. If the repair takes longer than expected due to our estimate, that's our cost, not yours.
Our dispatch center knows which tech is where in Andover in real time. When you call, you're not waiting for someone to drive from the next metro — you're getting the nearest available crew already loaded and on their way.
A licensed plumber in MA has passed both state-code exams and field-hour requirements. That credential means they understand code compliance, permit requirements, and safe working procedures that unlicensed contractors skip.
We document every repair with photos before and after. That documentation protects you if a question ever comes up about what was done and why.
We built our dispatch and repair process specifically to eliminate the three things customers hate most: not knowing when someone is arriving, getting surprised by the invoice, and having to call back because it wasn't fixed right.
A live dispatcher in Andover takes your call 24/7, collects the details, and immediately identifies the nearest available qualified tech. No voicemail trees, no callback queues on emergency calls.
Your MA-licensed plumber arrives with diagnostic tools — camera, acoustic sensor, pressure gauge — and completes a full assessment of the actual problem, not a guess based on your description.
Once the diagnosis is done, you receive a written flat-rate price. If you approve, we start. If you don't, you pay nothing for the visit on emergency calls during business hours.
Work is completed with properly rated materials, tested under operating pressure, and photographed before and after. You receive a copy of the job record for your files and warranty reference.

"The acoustic detection approach they used saved us probably $800 in floor tile restoration. They found the leak, patched it, and the tile work was minimal. Couldn't ask for a better outcome on a stressful day."
"Called at 9 p.m. on a water heater emergency. Tech showed up, assessed the unit, gave me a flat price for a new 50-gallon install, and had it running before I expected. No upsell, no hassle."
"I manage a small restaurant in Andover and grease trap maintenance is something I've gotten burned on before — unexpected charges, incomplete cleaning. Masters Plumbing Service quoted us a flat service fee, showed up on schedule, and gave us a post-service report. First time that process has felt actually professional."
"Root intrusion in my Andover home's sewer line. They ran the RIDGID camera before and after the jetting so I could see exactly what was removed. That transparency is rare and I appreciated it."
"Called about a burst pipe in the garage on a Saturday morning. The dispatcher told me approximately when the tech would arrive, the tech called 15 minutes before arrival, and the pipe was repaired within 90 minutes of my call. That efficiency during an emergency means everything."
"Whole-house repipe on a 50-year-old house. They did it in two days, kept disruption minimal, and the pressure improvement was immediate and significant. License numbers provided before they started — I checked them."
These questions come directly from Andover customers — we pulled them from call logs and review feedback because these are the things people actually want to know before hiring a plumber.
