Our Story

Built on trust, sustained by results

William O'Brien Plumbing & Heating started with a simple belief: that every homeowner in Boston deserves a plumber they can rely on — someone who shows up on time, does the job right the first time, and treats your home with the same respect they would their own.

Based in the 02124 area, we've spent over two decades serving residential customers throughout Boston and the surrounding communities. What began as a one-person operation has grown into a trusted local team, but our approach hasn't changed. We still answer our own phones. We still show up in uniform, on time, with a clear estimate before we touch a single pipe.

Whether it's a routine maintenance visit or a midnight emergency, the standard is the same: honest work, fair pricing, and a follow-up call to make sure everything is running perfectly.
