Henehan Construction is John Henehan's Andover design-build shop, and the record is a study in contrasts: a permit history that runs decades deep, alongside almost no independent customer voice anywhere except two very different Google reviews. The business itself has been around a long time — its website says more than 30 years, and BuildZoom's own editorial blurb (a bit more conservative) puts it at over two decades — pulling 24 permits across Andover-area and North Shore towns like Beverly, Marblehead, Methuen and Woburn for the kitchens, bathrooms, additions and whole-home remodels it specializes in. Neither BuildZoom nor Houzz has a single customer review on file for the company, so most of what's known comes from just two 2024 Google write-ups. One described a deck-house renovation — new walls, electrical, flooring, a new roof — and singled out the design process: attentive, detailed, and willing to suggest fixes like transom windows for more natural light. The other told a different story: a $2,500 "design deposit" that turned out to be a non-refundable fee rather than money applied toward the job, quotes the customer felt were inflated, and a refusal to return the money once they walked away. One more thing worth checking before signing anything: the company's Massachusetts home improvement contractor registration (#172582) shows expired in the state registry. BuildZoom lists a newer HIC number as active, but that hasn't been independently verified here — worth confirming current licensing status directly.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Henehan Construction. Use it to sanity-check bids, then get the real number in writing.

We hired John and his team to work on our deck house this past fall/winter. They redesigned our ground living space with new walls/electrical/flooring and placed a new roof. While there are some extra costs + deposits associated with the design process, there was also a lot of attention, detail and care. They listened to us and made helpful suggestions for how to get more light into the home (transom windows). As with any construction product (especially in an older home) there can be unforeseen costs but a lot of those extra costs were brought to our attention and discussed before we moved forward. I can say without a doubt that I trusted their team completely. They showed up as expected, were organized, respectable of our space, and made it possible to live in our house with a toddler during a 6 month Reno. With any larger projects, especially in a deck house, I would highly recommend John and his team. Every friend with a contacting background who has walked through the space was so impressed with their work. He maintained the original details of the house that we loved. We will definitely keep them in mind for future projects.
Potential customers of John Henehan should know that he charges $2500 for his construction estimates. His paperwork calls this payment a deposit but it is a fee since it does not get applied to the cost of construction. I would not recommend that you hire John Henehan because of this approach, which we found misleading. He was also unable to answer basic questions about the estimates and provided quotes that seemed very excessive and entailed much more work than was required to fix the problems. Once we decided not to use John's services, he refused to return the deposit.
