Francina writes from Oxon Hill, Maryland: "We just moved into a house which had two add-on rooms. These rooms are very cold in the winter. The house has insulation under the floor, which is lifted from the ground so you can see under this part of the house. The insulation was hanging down and the baseboard was torn up in spots. The owner took the baseboard down. What can be done to keep the house warm?"

Answer: It sounds like the add-on rooms were never insulated. I would have an insulation professional come inspect and make recommendations. You can find an Owens Corning Certified Energy Professional® contractor by checking the Web site.
