Mason Sky Enterprises gets hired for the big jobs. A December 2022 Angi reviewer had a whole house built in Kennebunk, Maine, and said the crew put it up to a high standard and worked quickly; a Google reviewer the same month wrote about a large addition on their own house and said they now know who to call next time. The company works out of Millbury and describes itself as family-owned, with Jason Shilinsky listed on its BBB page as president and owner. Its Massachusetts home improvement contractor registration, #183162, is active, and BBB lists it as accredited since 2016 with an A+ grade. The company also says it volunteers with the Homes For Our Troops program. What customers wrote about most in the Angi reviews from 2016 through 2018 is how Jason handled the talking. One September 2016 reviewer described him as thorough in the quoting; an October 2018 customer said the crew came when they said they would and brought good ideas; a December 2016 homeowner wrote that he flags a delay or an early start. In an October 2016 review of an $85,000 project, the homeowner credited him with helping design the layout, pulling every permit and finishing on time. Another October 2016 customer described him reinstalling the old toilet so a 93-year-old mother could use it mid-project and scheduling the work around their days off. Its written reviews run July 2016 to December 2022 — 18 of them on Angi, all five stars, and a 5.0 from six Google ratings. BuildZoom shows 18 permitted projects: kitchen and mudroom remodels, additions, carports, decks and re-roofs in Waltham, Lowell and Westborough, plus a 2020 commercial partition job in Brookline. Its Houzz profile lists a second line of work — masonry, hardscaping, concrete and excavation across 25 Central Massachusetts towns. Two things to raise on the first call. The website claims 20 years in business while BBB lists the company as started and incorporated 7/13/2015, so ask Jason how he counts it. And beyond the active Massachusetts registration, the numbers on the site — a Massachusetts construction supervisor licence CS-084205, plus Connecticut, New Hampshire, Rhode Island and Florida registrations — are the company's own listings; ask to see the one that covers your job. This is a good fit for an addition, a custom build or a gut remodel in Central Massachusetts, where owner involvement matters more than a big office. Get the scope and price in writing, ask for a certificate of insurance, and ask for a couple of recent references from jobs like yours.
Had a large addition put on our house by Jason and crew. Jason was responsive and re-assuring about the entire process. The addition came out great and it was a pleasure to work with them, and know who to call in the future when we need more house work done.
I recently had a home built for me in Kennebunk,Maine by Jason and the crew of Mason Sky Enterprises and I have nothing but praise for them, not only did they construct my home to the highest standards in an incredibly timely manner but they were also kind and considerate and endlessly patient when it came to my plethora of never ending questions which I am very grateful for. I highly recommend them for any job whether that be large or small. With much gratitude! SSgt.K Campbell USAF (Ret.)
