We are a proud member of The National Association of Home Builders (NAHB). We're also very proud of the professional certifications we have attained through our commitment to NAHB's remodeling training programs. These certifications not only means that we have the latest tools, techniques and expertise to complete your remodeling project but also that you don't have to just take our word for it.

NAHB Certifications are rigorous courses designed to qualify and recognize the best and brightest in the remodeling industry. In their own words, "NAHB is the leading advocate of quality construction, responsible business practices, and reliable customer services."

NAHB Certified Graduate Remodeler (CGR)

The Certified Graduate Remodeler (CGR) Certification means that we must meet and adhere to a nationally recognized set of business practices, rules and regulations including a robust evaluation and review of our past projects and field experience by the National Association of Home Builders.

The CGR designation means that you can be confident that we will provide you with a professional caliber of work. More information about the CGR program is available at the NAHB.org website.

NAHB Certified Aging-in-Place (CAPs)

The Certified Aging-in-Place (CAPS) Program has given us a unique skillset to address the needs of our older adult population. Our training includes a detailed understanding of the importance of an easy-to-access, obstruction-free environment that is both pleasing to the eye and easy to move through. We can address coding, standards and safety issues unfamiliar to most homeowners. Some clients have even commented that improvements made by a CAPS professional was a more affordable solution than moving to an assisted living facility.

An overview of the CAPS Certification Program can be viewed at the NABH.org website.

NAHB Certified Green Professional (CGP)

The Certified Green Professional (CGP) Program recognizes contractors who effectively incorporate sustainable (green) building products and energy efficiency into their work without driving up project costs.
