From the very beginning, Cecilio Builders has been defined by an entrepreneurial streak and a refusal to cut corners the same two things that turned a small carpentry outfit into a licensed general contracting company.
Cecilio Builders started small: two brothers, forward-thinking and entrepreneurial, building a carpentry business one job at a time. Word got around MetroWest, and the work got bigger kitchens, bathrooms, basements, additions until the small carpentry outfit had grown into a hard-earned, well-respected general contracting company.
Today the company is still run hands-on, with Silverio Silva and Wiler Filho overseeing every job from the first site visit to the final walkthrough. The name on the truck is still a family name, and the standard hasn’t changed: BUILD IT RIGHT, OR DON´T BUILD IT.
Built right, from the first visite to the final walkthrough.
Cecilio Builders, Inc. holds a Massachusetts Construction Supervisor License (CSL #110842) and Home Improvement Contractor registration (HIC #187610), and carries general liability insurance on every job. You can verify any Massachusetts contractor’s registration through the Office of Consumer Affairs & Business Regulation before signing a contract.
You can see and understand every step, from the site plan to the final invoice.
We’re meticulous about the small details, not just the big structural moves.
Honest pricing for the work performed no inflated estimates, no bait-and-switch.
We build with durable, finish-grade materials meant to last decades, not seasons.
We still build kitchens, baths, basements, and decks but additions and ADUs have become our specialty. Massachusetts homeowners are sitting on lots that just became a lot more valuable: since February 2025, the state requires every city and town to allow at least one accessory dwelling unit by right on single-family lots. That’s a real shift in what’s buildable on the property you already own, and it takes a crew that understands both construction and the zoning behind it to build one correctly.
We built our process around that: a real site plan before design, a zoning and setback check before permitting, and a single crew carrying the job from foundation to final finish no scattered subcontractors, no lost details between hand-offs.
Cecilio Builders is based in Southborough and builds additions and ADUs throughout MetroWest Massachusetts and the surrounding area, including:
No pressure, no sales script just an honest look at what your lot can hold.
