Ask This Old House Season 10 Episode 5 Insulation, Foundation

In Ask This Old House season 10 episode 5, titled "Insulation, Foundation," the experts tackle two important home improvement topics. First up, host Kevin travels to Connecticut to help a couple insulate their attic. The homeowners have been experiencing high heating bills and uneven temperatures throughout their house. Kevin explains the importance of proper insulation and the benefits it provides, including energy savings and improved comfort. He demonstrates how to install blown cellulose insulation, which fills every nook and cranny of the attic and provides an effective thermal barrier. The process is relatively simple, but Kevin emphasizes the importance of safety precautions when handling insulation, including wearing protective gear and sealing off the work area to prevent dust and debris from escaping.

Meanwhile, in Vermont, Tom helps a homeowner address a foundation problem. The house was built on a slope, and as a result, water has been seeping into the basement through cracks in the foundation. Tom explains the importance of a solid foundation and the potential dangers of water damage, including mold and rot. He demonstrates how to use hydraulic cement to repair the cracks and prevent further water intrusion. The process involves cleaning out the cracks and applying the cement mixture with a trowel. Tom emphasizes the importance of proper mixing and application techniques to ensure a strong and durable repair.

Back in Connecticut, Kevin returns to the attic to install an attic stair insulator. This product helps prevent heat loss through the attic stair opening, which is often a major source of air leakage in homes. Kevin demonstrates how to measure and cut the insulator to fit the opening and how to install it properly to create an effective seal.

Finally, in Vermont, Tom visits a local sawmill to learn more about the process of milling lumber. He meets with the owner and discusses the importance of sustainable forestry practices and the benefits of using locally sourced wood. Tom also explores the sawmill and sees firsthand how logs are turned into lumber, from rough sawing to planing and sanding.

Overall, "Insulation, Foundation" provides valuable insights and practical tips for homeowners looking to improve their home's energy efficiency and structural integrity. The experts demonstrate simple yet effective solutions that can make a big difference in the comfort and safety of a home.
