Our hundred year old Roland Park house seemed to be as drafty and inefficient in 2010 as I imagine it was in 1910. The contractor brought our home up to date in this regard quickly, courteously and neatly. The increased efficiency has not only lowered our bills, but has also made our third floor habitable on hot summer nights. Please know that I’ll be recommending Retrofit Baltimore to friends and colleagues in our neighborhood and beyond.

Peter Stine, Roland Park
