From the very beginning, my husband and I were impressed with the professionalism and expertise of Building Doctors owner and founder, Dan Thomsen. He was always available to answer our numerous questions prior to our doing the work and during the energy improvements. No hassle, no fuss and lots of help and information on the many available state, local and federal rebates. Dan helped us customize a plan that was cost effective and which resulted in an overall energy improvement of over 40%. Calling Building Doctors was the best investment we have made in the comfort, livability and value of our home. We are saving $ on our utilities too!
