The crew at This Old House take on some pretty big projects, which means they can only work on one or two houses a year. But homeowners have a virtual truckload of questions on smaller projects, and the This Old House crew is ready to answer. Ask This Old House solves the steady stream of home improvement problems faced by viewers - and the crew even makes house calls!
Host Kevin O'Connor and plumbing and heating expert Richard Trethewey head to Virginia to help a homeowner replace his old, electric water heater with a heat pump water heater that uses much less electricity. Then, up in the loft, Richard and Kevin, along with general contractor Tom Silva and landscaping contractor Roger Cook ask, "What is it?" Afterward, Roger and Kevin discuss propane-fueled mosquito traps and how to keep them working properly. Then Tom helps a homeowner install exterior trim against a very uneven stone chimney.
