This joist bay was not insulated during construction possibly due to the fact that a bathroom exhaust fan duct ran through it. This caused the homeowners to be uncomfortable in their home due to cold floors in the rooms above. Dr. Energy Saver Delmarva has a variety of insulating options that can be performed after construction without damaging or disrupting the structure of the home. If you are experiencing discomfort in your own home give us a call today to set up a no cost, no obligation inspection and estimate with one of our trained and certified Home Comfort Specialists.
