Koni Builders

Koni Builders is a small, owner-led Everett shop — Gleison Cavalcante out front — doing general contracting, carpentry, and finish work (decks, basements, painting) for homeowners across Massachusetts, and its own site says it also serves New Hampshire and Maine. The company describes itself as owner-accountable on every project and self-reports 15 years in business on its website, though its Thumbtack profile separately states 6 years — worth asking about directly. All eight reviews on file date to 2025, spread across Google and Thumbtack (the Thumbtack trio are labeled as copies of the Google reviews rather than independent ones). Google shows 5★ from 6 ratings. Reviewers describe a back-deck rebuild with rotted exterior trim replaced on budget and on schedule, a basement finished into what one homeowner called a cozy living area, and a full-home paint job delivered on time. Several mention Gleison and his crew directly, calling them clean, punctual, and easy to communicate with; Thumbtack shows a completed background check on him. BuildZoom could not verify an active license for the business — the only license entry on its profile is a masonry course number, not a trade license, and BuildZoom states there's no active license on file. It's worth confirming current registration before booking a larger job. BuildZoom's own permit-based score sits at 0, outside the top half of the Massachusetts contractors it tracks — a permit-history metric, not a customer-satisfaction one. For a smaller carpentry, deck, or paint job, reviewers describe fast, tidy work at a fair price. For a bigger remodel, confirm the license and the years-in-business claim directly before signing anything.
