About J.Sar Plumbing & Heating, a family-owned plumbing and heating company in Lowell, Massachusetts
About us
Built in Lowell. Run by the plumber you hired.
J.Sar Plumbing & Heating LLC is family owned and operated in Lowell, Massachusetts. We are licensed and insured in Massachusetts and New Hampshire.
When you hire us, you are not in a call-center queue. You talk to Jeremy Sar, a master plumber, and he is the one who shows up.
Who we are
A master plumber who stayed in the trade on purpose
Jeremy Sar was born in Massachusetts in 2001. His family settled here after fleeing Cambodia following the Khmer Rouge. He went to Greater Lowell Technical High School for plumbing, planned on college, then stayed in the field when he saw what he could build.
He worked at six plumbing companies to learn more than one shop’s version of the trade, and spent evenings at Lowe’s learning products and how to talk to people. Licensed at 21. Opened J.Sar Plumbing & Heating at 22. LLC in August 2024.
The company is still young. The standard is not.
“I try to make everything perfect, make it look nicer than it really needs to be. How a pipe system or water heater installation looks is part of doing a good job.”
What we stand on
The job has to look like someone cared
02
Master plumber accountability
The name on the van is the name on the invoice. Jeremy is on the phone and on the job.
03
Protect the house
Clean water, proper drainage, safe gas, heat that works. Plumbing is public health, not just a service call.
04
Options, then a decision
Tank or tankless, repair or replace, band-aid or do it once. We lay out the choices and work with the budget.
05
Local, not private equity
Long-term plan is a small crew and a few vans, not a sale. Greater Lowell Tech advisory board. Community giveaways and scholarship support.
