Before you commit, knowing what questions to ask can save you time, money, and potential headaches. Let's ensure you "let the light back in" with confidence.

Experience and Credentials: Are They Reputable?

A contractor's experience speaks volumes about their ability to handle your project. Don't be shy about inquiring into their background and qualifications. You want a team that understands the unique architectural styles and climate challenges of homes in our region. This foundational step helps ensure you're working with a trusted professional.

• Are you licensed and insured in Massachusetts and/or Connecticut?
• Can you provide references from recent customers in my area?
• What certifications or professional affiliations does your company hold?

Product Knowledge and Options: What Are My Choices?
