Before Dr. Energy Saver was called in for this job, this homeowner was wasting a lot of energy and money through his unsealed, uninsulated concrete crawl space. For 20 years since the home was built, an 8" x 16" crawl space door was allowing unconditioned outdoor air to enter the home and cause cold drafts, cold floors in the master suite right above the crawl space, overall discomfort, and higher heating bills.
