We have been self-performing carpentry work since Chairman and CEO Fran Colantonio started the firm as a carpenter in 1978.  All of our skilled craftsmen, many of whom have been with us for more than 15 years, are committed to performing only the finest work. Because Colantonio is signatory to the carpenters’ union, we have immediate access to additional high-quality carpenters as needed.

As a self-performing firm, we have the flexibility to schedule the work as needed or even step in and assist a struggling subcontractor, ensuring your project stays on schedule. Our deeply experienced crew hold each other and our subcontractors to the highest standards of quality work and safety practices.

“The Colantonio team was very sensitive to maintaining the historic integrity of the Jamaica Plain Library. They were careful to keep the historic features such as interior woodwork and glass elements intact even while making strong modern improvements throughout the building.”
