Mussato Building Group, Inc.

The jobs customers single out are the ones you touch every day: a new staircase that a May 2025 reviewer said changed the layout of the whole house, an outdoor kitchen good enough that its owner committed to the next project on the spot, trim work, and a deck rebuilt and repainted in November 2025 — on time and, that customer wrote, for less than the other bids. Mussato Building Group works out of Yarmouth and builds on Cape Cod: custom homes, renovations and additions, exterior carpentry and cedar siding, hardwood floors and cabinetry. The company describes itself as family-owned, names Joe Mussato as founder and owner and says he oversees every project himself, and puts its start on the Cape at 2004. Its Massachusetts home improvement contractor registration is active on the state registry; the construction supervisor number on its site, CS-121510, is the company's own listing. The written reviews are all from 2025 and 2026, and all of them are five stars — 21 ratings on Google. A designer wrote in January 2026 about collaborating on high-end residential work and Joe's attention to detail; a repeat client in July 2025 said they are kept in the loop on timing and budget across several projects; a homeowner in May 2025 described a Cape renovation finished on schedule. Read them closely, though, and a number are from people who work with the company — a design partner, long-time collaborators — rather than from homeowners who hired it. The most useful detail for anyone about to sign is in a May 2025 review: that customer went over budget after making changes mid-project, and wrote that the company was upfront about what the changes cost. Good conduct, and also a reminder to get the scope written down and to agree how change orders are priced and approved before the crew starts. The company also lists a 2022 Chatham Preservation Award on its site, which fits the older-home renovation work customers describe. For a custom build, an addition, or finish carpentry — staircases, cabinetry, trim — on the mid-Cape, this is a small owner-run builder whose clients come back for second and third projects. Ask for the written scope, the change-order terms, and references from homeowners rather than trade partners.
