How to Fix a Truss Floor From Squeaking

A squeaky floor isn't a threat to your home's structure, but it can get annoying. Most are caused by subflooring that isn't properly affixed to the trusses or joists underneath it. If you catch the sounds during construction and the finish flooring isn't laid down, you can fix it by driving more screws directly through the subflooring and into the truss. In a finished home, the process is different, but not difficult.

Instructions

- 1
  Go in your basement with a flashlight. Have an assistant walk around on the floor above until he hits the squeaky places. Shine the flashlight on the trusses and subflooring and mark the places with a pencil.
- 2
  Drill a diagonal hole through the truss's side at a 45 degree angle up toward the subflooring. Use a drill bit with a diameter just large enough that the screws you use slide through the hole without engaging the threads. Stop drilling when you hit the subfloor. This allows the screw to engage the subfloor but not the truss.

  Place a 3-inch long screw in the hole and screw it into the subfloor using a screwdriver. Tighten it so it sucks the subfloor down onto the top of the truss and holds it securely.
