T.J. Sillari Inc. is the Somerville plumbing and heating outfit reviewers call when a job is more than a quick fix — a hard-to-reach solder joint, a steam boiler that needs real diagnosis, a water heater that quit overnight. The company says it has served Somerville and the wider Greater Boston area, including Cambridge, Medford, Watertown, Waltham, Lexington, and Newton, since 1985. One reviewer called about a leaking water heater at 10 a.m. and had a new one installed that same afternoon. Another needed a copper joint soldered in a cramped, hard-to-reach space without scorching the surrounding wood, and a 2021 review describes the crew tracing a steam boiler problem to its actual cause rather than patching the symptom. Its Massachusetts plumbing license is active. Not every call gets answered promptly, though — a 2022 review describes a request for an appointment that never got a callback, and a January review flags a call that went unanswered. In late 2023, one customer was quoted $350 to replace washing machine valves ahead of a Home Depot delivery and felt the price ran high. For a tricky plumbing or heating repair in the Somerville area, the actual work has held up well across reviews going back to 2021 — worth confirming they've picked up the phone before counting on same-day help.
We noticed the water heater was leaking and called Sillari at 10 am. By 2 pm Mike was here installing the new one. They've been fixing our faucets, showers, and toilets for several years. Always great, friendly service. We highly recommend them.
No answer bad
The Home Depot team couldn't set up our new washer/dryer because the valves were rusted. I tried to find a plumber and contacted TJ Sillari's crew. They initially quoted $350 to replace the washing machine valves. Seemed a bit steep, but since there was a small leak, I had to shut off the water mains and I just needed it done. However, when they arrived, they muttered about things not being as they expected, and suddenly the new price skyrocketed to $750! They argued that the valves I had weren't available anymore, insisting on cutting into the drywall, tinkering with the pipes, and doing unnecessary work. Something didn't feel right, so I declined their offer. Instead, I went to Home Depot, bought two new valves for just $30 in total, and decided to try installing them myself. Surprisingly, it wasn't too challenging, even for someone like me without any plumbing experience. I'm not sure if they were after extra holiday cash and thought they could pull a fast one on me, or if there's some other reason behind it, but be cautious...
Mario and his team went above and beyond for to connect my new washer/dryer. Highly recommend!
No return phone call for an appt. Moving on.
