Big Blue Plumbing & Heating is a Medford plumbing and heating company, and one recent customer's account of a leak coming down a 100-year-old cast iron stack pipe shows the work: Randy diagnosed a cracked main waste stack, and he and Julio opened the wall to examine the crack. That customer wrote that Julio came back ten minutes after leaving to replace a leaking basement valve, and that Randy and Mohammed returned a few days later to repair the stack, a job that took most of the day. The company says it has been in business since 2007, serving Medford, Somerville, Cambridge and surrounding communities. Its Massachusetts plumber license, number 15303-PL-M, is active on the state registry. On Google it holds 4.7 stars from 54 ratings, and its BBB page shows an A+ grade. A recent customer whose water heater went on the fritz said Stacey coordinated the replacement by phone, and that the price and promptness were welcome. A 2026 customer who had used Big Blue a few times over 15 years had them fix a pipe in the basement and wrote that prices were reasonable and clearly explained. A 2025 customer said Randy fixed a leaky shower, and that it was useful to hear what caused the problem and the different options to fix it. A 2024 customer with a toilet problem said Big Blue showed up within 20 minutes and rectified the problem in less than an hour. A 2023 customer whose AC wasn't working emailed overnight on a Monday, had an appointment by Tuesday morning and had the AC fixed by 2pm Wednesday. A 2022 customer said the company replaced antique plumbing in the basement of an old house, later replaced the boiler and water tank, and coordinated relining the chimney. A 2024 Reddit commenter in r/Somerville described Big Blue installing a ductless system and praised the support. A 2025 Reddit commenter who had been on a condo association board said the building manager called Big Blue only for complicated plumbing, and found them too pricey for really routine stuff. A 2025 Reddit commenter said a quote from Big Blue for HVAC upgrades seemed high. A recent customer who booked AC maintenance said the technician only changed and cleaned the filter, did nothing about the specific issues they raised, and charged $325. A 2025 customer who scheduled a kitchen sink fixture replacement said no one showed up on the appointment day, and that the office then put it down to a miscommunication about confirming the water shutoff. A 2023 customer who said the work on a garbage disposal installation was great wrote that the office raised the quote from $675 to $695 and never answered two emails asking for the unit's model number.
“Before moving a couple of years ago, I was on the board of a large condo association. Our building manager would only call Big Blue for complicated plumbing stuff, they never failed to deliver. They were too pricey for really routine stuff, though.”
“Agreed, Kevin's a gem. On our [2024 market benchmark](https://www.reddit.com/r/boston/comments/1agauzo/i_benchmarked_23_more_heat_pump_installers_but/) I said "Kevin may be the nicest owner I've ever met". Honestly, if you're going to pay *that* much, you should just work with Big Blue rather than one of the Sila companies”
“This is great! I had Big Blue do some plumbing for me last year and they were great to work with. High quality work. I got a quote this year from them for HVAC upgrades and my quote was similar to yours from them. I did think it seemed high and your research confirms that. But if their HVAC work is a similar quality to the plumbing it may be worth it. I agree that Kevin is a delight. Remembered that I have a dog and wanted me to let him out to say hi”
“Great owner. Kevin is super friendly, but retiring soon :(”
“Seeing Green Tech and Big Blue Plumbing and Heating being recommended in the area - curious if anyone has used them.”
I used Big Blue Plumbing for AC maintenance based on a neighbor’s recommendation, but I was highly disappointed. The technician did a completely perfunctory job, only changing and cleaning the filter. Even though I explicitly mentioned specific issues I’ve been experiencing, he did absolutely nothing to address them. Charging $325 for basic maintenance I easily could have done myself is unacceptable. I would not recommend their services.
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!
I’ll try to make this one short because if I wrote every reason that I think Big Blue is the best, this review would be way too long to read. Tale of woe: I had a major leak coming down the 100-year-old cast iron stack pipe in my house. A few days before, I’d called a plumber who came over and told me he’d be back after the weekend to figure out the problem. He never showed up, so I Googled plumbers and came upon Big Blue. After reading all of their 5 Star reviews, I called Big Blue and the receptionist (Stacey) sent Randy that afternoon. He did some detective work and correctly diagnosed a cracked main waste stack. Randy and Julio opened the wall to examine the extent of the crack, and it was wide and long — not good. Randy and Julio did as much as they could do that day, and as they were packing up, I mentioned to them that I had a leaking valve in the basement — something I caused that morning. Yeah, when it rains, it pours. Julio offered to look at it, and suggested ways I could fix the leak, if I wanted to try. Ten minutes after they’d left, Julio rang my doorbell. “My conscience won’t let me leave you like that,” he said, and he offered to replace the valve. Randy made it over to the supply house in Medford before it closed, and they replaced the valve. I’m not making this up. A few days later, Randy and Mohammed returned to repair the stack. It took most of the day to do it as the section of damaged pipe was long and the job was complicated. They did a fantastic job. Everybody at Big Blue is super-nice, from the secretarial staff (Stacey and Linda) to every plumber I met. They are quiet, clean, prompt, very knowledgeable, and professional. If I ever have another plumbing problem, I know who I’m calling. There is a reason for all of those 5 Star reviews. Thanks, Big Blue.
I've used Big Blue a few times over the past 15 years. Just had them come around to fix a pipe in the basement. Always done right, clean, and courteous. Prices are reasonable and clearly explained. I wouldn't use anyone else!
Kevin is very experienced and knowledgeable, as is Josh. We really appreciated them answering our many questions! Their team does good work and their rates are reasonable. We'd recommend Big Blue for anyone needing plumbing services (except sewer scopes, I don't believe they offer those)
