About Spectrum

Delivering exceptional design-build remodeling for more than a decade.

Our Story

Spectrum is a family-owned and award-winning design-build firm serving homeowners in the Washington, DC and Montgomery County area since 2011. As the owner of Spectrum, I [re-]discovered my talent as a carpenter, contractor, and builder over twenty years ago. I left my day job and haven’t looked back since.

Over the years, we’ve expanded our team of master builders, designers, architects, project leaders, superior craftsmen and tradesmen to create transformative remodeling experiences for our clients. As a result, they have hired us again and again for multiple projects of high-quality remodeling and renovations. The care and standards we put into every project is because we love what we do just as much as you love your home. It is our mission to make your home function for your specific needs, and turn it into a space that you’ll love spending time in with your family and friends!
