"Daniel at Big Blue was amazing! I was having a running toilet that was causing my water bill to spike. Daniel came when he said he would. He was great at communicating with me. He was so friendly and great at his job! He replaced the toilet and it works perfectly. I now feel like I have a Plumber for Life.!! I recommend Daniel at Big Blue and if I need services in the future, that is who I'm going to call."

"My ductless / heat exchange AC unit has been running for 15 years, I never had it cleaned. It was a mess! I was blown away by how professionally, unobtrusively, and thoroughly the team that arrived this morning handled this messy job. I peppered them with questions, they were very knowledgeable and kind of passionate about what they do. I went with Big Blue after reading other people's reviews here, and just wanted to confirm they're a great company with great people."

"Had a water heater go on the fritz and Big Blue were quick to help. Stacey, who ran point on the phone, was so communicative and helpful in coordinating the replacement of the water heater. Price and promptness were all very welcome. Thank you!"

Expert Craftsmanship & Reliable Solutions

Every service is backed by our licensed technicians and complete warranty.

Hydronic Boiler & Heating Service

As a heating equipment supplier, we service, repair, and replace hydronic boiler systems — including freeze-protection checks, zone valve service, and pre-winter tune-ups. We also clean and maintain ductless heat-pump and mini-split units to keep them running efficiently for decades.

Repiping & Cast-Iron Stack Renewal

Historic triple-deckers across Medford, Somerville, and Cambridge often still run on corroded galvanized supply lines and scale-narrowed cast-iron sewer stacks. We plan and execute full repipes and stack replacements with minimal disruption — restoring water pressure, water clarity, and reliable drainage.

About Us

About Big Blue Plumbing & Heating

Big Blue Plumbing & Heating has built its reputation one Medford home at a time — and many of those relationships go back 15 years or more. From the triple-deckers lining Medford Square to the colonials branching out through Cambridge, Somerville, Newton, Brookline, and Watertown, we know the housing stock inside and out. Historic Boston three-family homes came of age on galvanized steel supply lines and heavy cast-iron drainage, and our team has the specialized experience to upgrade those aging systems without tearing your house apart.

When you call Big Blue, you get technicians like Daniel, Kevin, and Josh — experienced, knowledgeable pros who show up when they say they will, answer your questions patiently, and treat your home like their own. Every job starts with clearly explained, reasonable pricing before a wrench is turned, and every job ends with the work area left cleaner than we found it. That's why customers tell us they've found their 'plumber for life.'

As a full heating equipment supplier and service shop, we do more than stop leaks. We replace failed water heaters fast, service ductless heat-pump systems, and keep hydronic boilers tuned and protected against New England's deep-winter freeze cycles — because a boiler that goes down during a Medford cold snap is an emergency, and we treat it like one. Honest work, fair prices, and a phone that gets answered: that's the Big Blue way.
