McMahon Construction works out of 10 Flint Rd in Tyngsborough. Its Massachusetts home improvement contractor license 189214 is active on the state registry, with Patrick W. McMahon as the license holder. On Google it holds 5★ from 6 ratings. In an August 2025 review, a customer said Pat did a complete rebuild of their bathroom, and that he helped them understand the choices involved and the pros and cons of their ideas, and settle on the final outcomes based on tile, style and cost. In a June 2025 review, a customer said Pat and his team had recently renovated a spare room in their house for their first baby's nursery, and described wallpaper, perfectly aligned shadow boxing and the neatest paint job ever. In February 2026, a reviewer thanked Patrick for the work at their place in Billerica, getting it all prepped for the VA inspection. A March 2022 reviewer said Pat and his team kept them up to date on how the process was going, and that he kept them aware of any supply issues. A January 2022 reviewer said he and his staff were on schedule. A sensible call for a bathroom rebuild or a spare-room renovation — ask about tile, style and cost when you go over the choices.
