Signature Basement Design LLC is based in Auburn and focuses on basement finishing and remodeling across Central Massachusetts. The company says it has more than 30 years in the contracting industry and is led by co-owners Leo DosReis and Ana Paula Dos Reis, with Leo serving as sales manager and CEO. Its website describes basement design, finishing systems, flooring, wall and ceiling products, windows, lighting, electrical work, and related remodeling services. Homeowners consistently describe finished basements, bathrooms, flooring, stairs, custom tile, trim, doors, and storage areas. Recent Google reviews praise the team's communication, design guidance, responsiveness, workmanship, material quality, and ability to keep projects organized. Reviews also describe work in older homes and projects involving plumbing, electrical work, permits, moisture-resistant materials, and customized layouts. A 2025 review reported a 500-square-foot basement project that ran from January through July; the homeowner attributed several weeks of delay to city inspections and a sick subcontractor while still rating the finished work highly. The strongest pattern is detailed, positive first-hand feedback about basement transformations and the people managing them. Multiple homeowners specifically mention Leo and Lucas, prompt communication, design revisions, clean crews, and attention to custom requests. The company presents itself as a Total Basement Finishing authorized contractor and its website lists contractor ID CSFA106514; directory pages separately list self-reported Massachusetts trade license number 208844 expiring June 6, 2027. Those credentials should be confirmed with the relevant state or local authority before relying on them. This looks like a fit for homeowners planning a substantial basement remodel, particularly when the project combines layout, finishing, bathroom, flooring, stairs, and other trades. Before booking, confirm the exact scope, permit responsibilities, timeline allowances for inspections and subcontractors, warranty terms, and which license or registration applies to the work.
10/10 would recommend. We did a full basement redesign (bathroom, living space, stairs, plumbing, electric, etc) and the craftsmanship, attention to detail, and outcome exceeded expectations. I don’t think you can find someone more trusting than Leo and his team. Happy to be a reference for anybody on the fence.
Great communication; the basement and bathroom remodeling looks great and the space was well done.
Signature Basement Design did our basement in 2025. From the initial discussion to final completion, Leo and his team were highly professional and prompt. There were no unexpected surprises with Leo and Lucas in regular communication. They took the time to work us on the design and optimized the space. We are really happy with the basement and would highly recommend Signature Basement Design.
The customer praised the construction, quality materials, design, permits, and lack of issues after more than a year.
Leo and his team were professional, efficient, responsive, and easy to work with on a finished basement.
