This hour of "At Home with Gary Sullivan" is all about tackling home improvement projects and answering listener questions. Gary shares tips on how to check for leaks under supply valves and pipes, which can lead to costly repairs if left unchecked. He also discusses the importance of maintaining a healthy humidity level in the home, especially during the spring and summer months. Additionally, Gary takes calls from listeners, including one about converting a toilet to a bidet and another about dealing with tar-like specs on a newly refinished floor.
