Sean Tierney Construction

Sean Tierney Construction works out of 29 Hartford St in Bedford, and the man behind it is Sean P. Tierney — the name Massachusetts has on file as the holder of Home Improvement Contractor registration 177422, which the state registry confirms is active. BuildZoom's permit history shows 34 permitted projects under his name, the kind of paper trail a small owner-operated outfit builds up over years rather than months. Roofing is what he is most visibly hired for, and the one written account from a customer is also the sharpest word of caution here. In April 2020 a homeowner rated a $14,000 tar-shingle roof 2 out of 5 and described waiting six weeks for a measurement, then being told he would come and stood up over three more weeks. The same account describes trim materials and quoted zinc strips forgotten until late, gutters rehung sloppily with downspouts left unadjusted, broken chimney mortar, and a new bathroom vent that dripped for ten days after a minor ice dam. That homeowner also wrote that final payment was asked for before the siding and trim were finished, and that after promising to come back for repairs he stopped returning calls. The shingles themselves, they said, looked fine. The word of mouth runs the other way. In a July 2024 Boston thread a self-identified local plumber named Tierney as one of only two contractors he could think of who could take on a custom build, and a second commenter in that thread said Tierney "has better guys" and that both men "do solid work, no cutting corners." Those are trade peers and neighbours talking, not customers describing their own jobs. So the written history is dated and divided: one detailed 2020 complaint against 2024 recommendations from people in the trade. If you are weighing him for a roof or a renovation, ask for two or three recent local references, put the punch list and the final-payment schedule in writing before work starts, and confirm both the home improvement registration and the construction supervisor licence CS-107299 — the latter shows up only as a BuildZoom listing — directly with the state.
