Henehan Construction is an Andover design-build firm that draws the job and then builds it — kitchens, bathrooms, additions and whole-home remodels, offered on design-build, cost-plus or time-and-materials terms. John Henehan founded the company and owns it, and its site says it has worked across New England for more than 30 years. The work shows up in permits and photos. BuildZoom lists 24 permitted projects, with permits pulled in Beverly, Marblehead, Methuen, West Newbury, Woburn, Burlington, Tewksbury and Somerville, and Houzz carries six project photo sets from Andover, North Andover and Methuen — kitchens, bathrooms and a basement. On Google the company sits at 3 stars from two ratings. In a review posted in July 2024, a homeowner described the ground floor of their deck house redesigned the previous fall and winter with new walls, electrical and flooring, and a new roof put on; that same reviewer mentioned extra costs and deposits tied to the design process. The money question is worth settling first. A customer writing in May 2024 said Henehan charges $2,500 for a construction estimate, and that the paperwork calls the payment a deposit even though it is not applied to the cost of construction. On the licensing side, the Massachusetts registry shows home improvement contractor registration #172582 as expired; BuildZoom lists a second registration, #208049, and a construction supervisor licence, CS-061755, which Houzz lists as well. For a homeowner who wants design and construction from one firm and is prepared to pay for the design phase, Henehan is a reasonable call. Get in writing what the $2,500 covers and whether any of it comes off the construction price, and ask for the registration number the company is working under so you can check it against the state register.
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.
