What does a remodeling project cost in Greater Boston?
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Graumann Builders, Inc.. Use it to sanity-check bids, then get the real number in writing.
Custom millwork — stairs, railings and built-ins praised by a repeat client
Repeat clients — one homeowner describes multiple kitchens and millwork jobs
Trade endorsements — designer, painter and supplier all vouch for the finish work
Commercial capable — a March 2026 office renovation ran on schedule
Six reviews total — all posted in a single stretch of March 2026
Mostly peers — designer, painter and supplier, not homeowners
Syndicated copies — HomeAdvisor's four are the same Google reviews
Tenure claim — Houzz says 22 years, records say founded 2018
The most useful thing on Graumann Builders' record isn't a review — it's the registry. Its Massachusetts home improvement contractor registration, #209328, is active and held in the company's own name, and the Better Business Bureau accredited it in February 2026 with an A+.
The company is Fernando Graumann's. He founded it in 2018 and describes himself as a licensed builder in three states with more than 22 years in construction; BBB records the business as a 2018 corporation with one employee. The work is residential renovation at the higher end — kitchens, bathrooms, whole-home transformations, decks and outdoor living, siding and painting, plus ground-up custom homes, with Houzz putting typical jobs between $10,000 and $500,000.
The most detailed account comes from a repeat client writing in March 2026: two kitchen remodels — semi-custom cabinetry in the primary residence, well-chosen stock cabinets for a rental — plus new stairs and railings and a custom-built bench, all of it described as organized, transparent and well-managed. A commercial client the same month described an office renovation kept on schedule and finished cleanly.
Here's the caveat, and it matters. There are only six reviews in total, every one of them posted in a single stretch of March 2026, and most were written not by homeowners but by people in the trade: an interior designer who collaborates with him, a painting contractor who has known him seven years, a kitchen-and-bath supplier who has worked with him since 2005, and a tradesman who watched him work. Peer respect is worth something, but it isn't the same as a homeowner's account of their own job, and HomeAdvisor's four are syndicated copies of the same Google reviews rather than independent ones.
There's also a tenure wrinkle: Houzz advertises '22 years in business' where the state and BBB records show a company incorporated in 2018 — the 22 years is Fernando's own time in the trade, not the firm's.
So: a properly registered, recently BBB-accredited Framingham builder with a real portfolio across Wellesley, Southborough, Belmont, Winchester, Malden and Sherborn, and a licence you can verify. The thing to ask for is references from homeowners whose projects match yours in size — the written record simply doesn't have many yet.

I've known Fernando from Graumann Builders for over 7 years, and every project he's been involved in has been exceptional. From full spec homes to detailed kitchen and bathroom renovations, the quality of work consistently stands out. His attention to detail, professionalism, and pride in craftsmanship truly show in the final result. I highly recommend Graumann Builders and would be happy to answer any questions about my experience.
As the owner of Oliver James Interiors, I have had the pleasure of working alongside many builders over the years — and Fernando is truly a rare find. Fernando is a gem, not only as a builder but as a human being. It is incredibly difficult to find someone who is so in tune with the fine details, who consistently delivers excellence in craftsmanship, and who approaches every request — no matter how big or small — with a genuine can-do attitude. His level of care and precision elevates every project we collaborate on. From a designer's perspective, what sets Fernando apart is the way he supports both the creative process and the client experience. He communicates clearly and consistently, responds promptly, and operates with a level of trust and professionalism that makes our job seamless. He goes out of his way to ensure we feel supported as the design team while also making his clients feel confident and well cared for every step of the way. He is one of our favorite professional partnerships, and we wholeheartedly recommend Fernando and his team. Any client would be fortunate to work with him.
I've had the pleasure of working with Fernando since 2005, and he's one of the most hardworking, reliable professionals in the construction industry. Our most recent project was a new home build completed last year. I can say firsthand that his honesty, sincerity, and dedication to his craft are second to none. I'd highly recommend him to anyone looking for top-notch construction expertise."
We had a great experience working with Graumann Builders on the renovation of our office. The entire process was smooth from start to finish. Their team was professional, organized, and easy to communicate with. They kept the project on schedule and paid close attention to every detail. The quality of the workmanship was excellent, and you can tell they truly care about delivering a clean and well-finished result. The office renovation turned out even better than we expected. If you're looking for a dependable contractor for commercial renovation or construction projects, I highly recommend Graumann Builders.
Graumann Builders has completed multiple renovation projects in my home, and the results have been exceptional every time. They delivered two fabulous kitchen remodels—one featuring beautifully executed semi-custom cabinetry for our primary residence, and another using well-chosen stock cabinets for a rental property, both tailored perfectly to their purpose and budget. In addition, their craftsmanship truly shines in the custom millwork: stunning new stairs and railings, along with a custom-built bench and cabinetry that feel both timeless and thoughtfully designed. What sets Graumann Builders apart is their organization, clear communication, and deep expertise. The process was smooth, well-managed, and transparent from start to finish. Fernando Graumann is a true professional—knowledgeable, detail-oriented, and clearly passionate about quality construction. If you're looking for a builder who combines craftsmanship, reliability, and design sensibility, I would confidently recommend Graumann Builders to anyone considering a renovation or custom project.
