Plumber in Lexington, MA

Two Very Different Towns Sharing One Town Line

Most towns on our map have one housing story. Lexington has two. There’s the colonial and Victorian core along Route 2A, and then there are four planned modernist neighborhoods built between 1947 and 1963, which are now old enough to be replacing everything their architects specified. The work is different in each, and knowing which one you’re standing in decides how a job gets quoted. Opus covers 02420 and 02421 out of North Billerica, under a Massachusetts master plumber licence.

Two Housing Eras, Two Kinds of Job

What That Means for Your Equipment

The older core.

Colonial through Craftsman, mostly hydronic, often steam, with systems altered by decades of different hands. Same work we do across Winchester and Woburn: boilers, radiators and original supply piping.

The modernist neighborhoods.

Six Moon Hill, Five Fields, Peacock Farm and Turning Mill were built between 1947 and 1963. Sixty-plus years on, the original mechanical equipment is long gone and the first replacements are often due too. These houses were designed around their systems rather than having systems added later, which changes what a swap involves.

Glass is a heating problem.

The mid-century houses were built with large glazed areas, and that shows up directly in a heat loss calculation. Sizing a boiler off the old nameplate in a house like that repeats a decision made when the glazing was single-pane.

What We Get Called For in Lexington

Plumbing and Heating Services Across the Town

Sizing, not matching.

Boiler replacement works room by room with window area counted in, rather than copying whatever is down there now. In a town with this much glazing that’s the difference between a boiler that fits and one that was guessed at.

Annual service and no-heat calls.

Boiler service and repair takes in the September visit, the January emergency, cold zones and noise, steam systems included.

Water heaters.

Gas and electric, repair and replacement. Water heater installation in these houses often means a closet or a mid-level utility room rather than a full cellar, which changes the access more than it changes the job.

Leaks and hidden water.

Leak detection traces it back to the source before anything is opened, which matters more in a house with finished lower levels and exposed ceilings than in a bare cellar.

Check Us Before You Book Us

Licence, Permits and Inspections

Lexington homeowners research a contractor more thoroughly than almost anywhere else we work, and that suits us.

The licence is public.

Massachusetts master plumber 16813-PL-M, and the state runs a Check a License portal where you can confirm it’s active and see that it’s a master rather than a journeyman. Only a master can pull your permit.

The permit isn't optional and it isn't an extra.

A water heater, a boiler or any gas work gets permitted and inspected. We pull it, meet the town’s inspector and hand you the signed card, and that time sits inside the quoted number rather than on an hourly line.

Ask the next quote the same questions.

Who pulls the permit, is labor covered as well as parts, and what happens to the price if something unexpected turns up. The answers tell you more than any review does.

Emergency Plumber in Lexington

24 Hour and Same Day Calls

A person answers around the clock, not a machine.

Call now for water you can’t stop, sewage backing up, or no heat in freezing weather. Shut your main valve first. With 24/7 emergency plumbing the written price holds at two in the morning the same as at two in the afternoon.

It can wait if it’s a dripping faucet, one slow drain or a running toilet, and we’ll tell you that rather than take the night booking.

Nearby Towns

Where Else We Work

Winchester

North-east, where a plumber in Winchester spends most of the week on hundred-year-old hot water systems other companies would rather replace than repair.

Burlington

North, a town built almost entirely inside one decade, so a plumber in Burlington sees the same equipment come due in waves.

Wilmington

North-west, carved out of Billerica back in 1729, which is why a plumber in Bedford is never far from the shop.

Lexington borders five of the fourteen towns in our service areas, so a job here often follows one a town over the same morning.

Questions From Lexington Homeowners

Local Answers

We have a mid-century house. Is that harder to work on?

Different rather than harder. The mechanical space is often a closet or a mid-level utility room instead of a full cellar, access can be tighter, and the original layout was designed around the equipment. It mostly affects how long a swap takes and what has to come apart, which is why we look before quoting rather than after.

Our house has walls of glass. Does that change the boiler?

It should. Glazed area is one of the inputs in a heat loss calculation, and it’s the reason sizing off the old nameplate goes wrong in these neighborhoods. We work from the house as it is now, including any windows that have been upgraded since.

How do I check you're actually licensed?

Look up Massachusetts master plumber 16813-PL-M on the state’s Check a License portal. It’ll confirm the licence is active and that it’s a master licence, which is the one that can pull your permit. We’d rather you checked.

Do you charge more to come to Lexington?

No. The flat written price is the same in every town we cover, with the driving inside it rather than added on.

Do I need a permit for a water heater or boiler here?

Yes, and the town inspects afterwards. You should end up holding a signed card. Ours is priced into the quote rather than billed separately, and an unpermitted install tends to surface during a sale.

The Boiler Standard

Boiler Work Is the Job We Take First

A lot of crews would rather pull your boiler out and sell you a new one than actually work on it, and plenty won’t touch steam at all. Boilers are our first call, not our last. Rick services, repairs and replaces them himself, steam systems included, and when yours still has years left in it you’ll hear that instead of a quote. In a town where people check things properly, that’s easy enough to verify: ask what he found, ask what he left alone, and ask why. He spent close to 20 years on New England systems, most of it union, working the same houses these boilers are sitting in today.

“Had a leak in my water heater tank. Ricky and team arrived very quickly, same day to assess the situation. I asked if we could avoid swapping out the water heater and just buy the parts needed to fix (I was being cheap!) – he did he absolute best (a few hours) trying to extract the old part and replace it with a new one. He tried far longer than any other plumber would have tried. After several hours of attempts we all came to the conclusion that it simply wasn’t coming out. I ran to Home Depot (it was Saturday) and grabbed a water heater. Ricky and team had it installed within 15 minutes and my new unit is working perfectly.

Very impressed with Ricky’s transparency and honesty. Most others wouldnt have given me the time of day…”
