I want to give a shoutout to Mark Inman of Greenmark Home Performance. Mark recently helped us through some energy efficiency and aesthetic improvements to our 40-year old house. The changes made in the HVAC system and in added insulation and sealing have resulted in far lower energy bills and a much more comfortable home. The aesthetic changes have greatly enhanced the curb appeal of our home evidenced from the favorable comments of our family, friends and neighbors. Mark has very solid advice for improving energy efficiency and keen eye for design. The workers were all top-rate. We feel comfortable recommending Mark to anyone looking for help with their home improvement projects.
