Our services

Full-service general contracting, built around additions & ADUs.

Cecilio Builders is a licensed Massachusetts general contractor. Additions and accessory dwelling units are where the crew spends most of its time but we still handle the kitchens, baths, basements, and decks that come with growing a house.

Where we focus

Two ways to get more out of your lot.

Whether you need more room for your family or a separate space with its own purpose, we help you make better use of the property you already own. Explore the two ways we can add space, function, and long-term value to your home.
