A squeaky floor is an annoying problem in a house, but this noise-proofing joist tape promises quieter times. Installed between the floor joists and subfloor, it creates an airtight seal that stops friction and eliminates the noise created by loud foot traffic. It comes in three standard widths: 1 7/16 inches, 2 1/4 inches, and 3 inches. Cost: $19 for a 100-foot roll. The Green Glue Co. 866-435-8893. www.greengluecompany.com
