We can’t say enough about working with Neil and his team! They have renovated practically every room in our 90 year old house and have done excellent work. They have been so nice to work with professional, responsive, creative, and conscientious. We definitely recommend Neil and the team!”

Neil and his team were truly amazing. We chose Neil for a major project and it gave me confidence that his guys had been with him for a very long time. Neat, clean, hardworking with terrific results. They do it all the time.

We worked with Jannsen Design on a full renovation of our 1920s bungalow. Neil and his team did an outstanding job from the initial design to permits, paperwork and budget, construction to completion. The craftsmanship was beautiful and high quality, and we couldn’t be happier with the result.”
Matt Koeppe
Washington, DC.

We worked with Neil and his team to renovate our town house, which had been neglected for decades. Neil provided guidance, support, and timely focus to get the job completed as scheduled. Neil was readily available, and with good nature, to talk us through any aspect of the process and put our minds at ease as challenges arose. We just hope that Neil and his loyal team will be available if needed in the future!
