A water heater let go while the owners were away on vacation and flooded the basement. Adriano Gontigio's crew cleared the space, pulled out the water-damaged walls, flooring and insulation, rebuilt it and stayed inside the budget; the homeowner wrote it up in December 2025.
Piacentini Construction is a Milton general contractor working across Greater Boston — Cambridge, Brookline, Waltham, Lexington, Weston, Needham, Quincy, Hingham and their neighbors — on renovations, remodels, carpentry, painting and new construction, and the company says it has been at it since 2012. Two registrations hold up against the state registry: the company's home improvement contractor registration, 189653, and Adriano Gontigio's own construction supervisor licence, CS-111697. The Better Business Bureau grades the company A+.
The people hiring him are often experienced ones. An architect wrote in December 2025 that she brought him in to renovate her own South End condo and will use him again on the next project. Another client that month, twenty years into projects on various homes, called his estimates accurate and detailed. A third said that of every contractor they spoke with, he was the only one who listened to what they wanted instead of telling them what they should want.
The work spans a wide range. An April 2026 customer had a kitchen and bathroom remodeled; another had a home addition finished on time, with no unpleasant surprises in the finish work. A December 2025 client had the whole house redone, basement through kitchen and bathrooms. In March 2026 the crew did exterior painting and repairs at one house and cleared out an entire apartment in two hours at another.
Two habits get named over and over: the crew shows up when it says it will, and it cleans up. An April 2026 reviewer wrote that everything is left organized at the end of the job; a June 2026 client said the same about the end of each day. And in April 2026 a customer wrote that the advice they got was about what was genuinely needed, not extra work to push up the bill.
Google sits at 5.0 across 31 ratings and Houzz at 5.0 across 12. The written history is recent and dense — it begins in October 2025, and 19 of the reviews landed in the last six months.
For a Greater Boston renovation where you want a licensed builder who will listen, price it accurately and finish when promised, this is a strong call. Ask for the detailed written estimate customers keep praising, and confirm which crew will be on your job.
