What we do
Plumbing and heating, done by the person you hired
Five core services. Every job starts with a call to a master plumber, not a call center.
02
Water Heaters
Tank, tankless, heat pump, electric, gas, propane, and oil-fired replacements. Mixing valves, expansion tanks, and leak shutoffs when the job calls for them.
About Water Heaters03
Boilers & Heating
Oil and gas boiler replacement, hydronic piping, circ pumps, and the board work that looks as good as it runs.
About Boilers & Heating
04
Water Filtration
Whole-home conditioners and filtration. Halo systems, sediment and carbon filters, and the water quality work most homes skip until fixtures start failing.
About Water Filtration
06
Commercial Plumbing
Restaurants, shops, and small commercial fit-outs. Drainage, venting, water, gas, and inspections that pass.

This is not a dispatch desk. Jeremy Sar is a master plumber, licensed at 21, company founded at 22. You call the owner. The owner shows up.
Family owned and operated out of Lowell. Licensed and insured in Massachusetts and New Hampshire. The work is built to look finished — copper on black boards, hangers where they belong, pitch that drains — because how an install looks is part of doing the job.
“You don’t work for yourself. You work for your clients.” — Jeremy Sar

02
We look at the work

Code, pitch, support, expansion tanks charged, leak protection when it belongs. Then we leave it looking finished.
Common questions
Do I get a master plumber, or a junior tech?
You speak to a master plumber on the phone and you get a master plumber at the door. That is the point of this company.
Are you licensed in Massachusetts and New Hampshire?
Yes. Licensed and insured in both.
Do you only work in Lowell?
We are based in Lowell, MA and work greater Lowell and southern New Hampshire — including jobs in Dracut, Westford, and Nashua.
Can you replace a water heater the same day?
When stock and access allow, yes. We have pulled heaters on short notice — including a Sunday morning leak — and had hot water back on the same day.
Do you do commercial work?
Yes. Restaurants and small commercial fit-outs, including a Japanese noodle shop in Westford that needed new drainage, venting, water lines, sinks, and gas safety work. It passed inspection.
Should I text or call?
Call (978) 905-9269. That is the fastest way to get a real answer.
