Silencing Floor Squeaks Instructions

  • Silencing Floor Squeaks

    Squeaky floors are usually caused by floor joists, sub-floors or finished floors rubbing against each other as you walk over the area. Other causes include loose pipes or heating ducts rubbing against the joists. Squeaks can usually be eliminated by “tightening up” the loose boards, pipes or ducts. Fixing squeaks is best accomplished from a basement or crawlspace under the floor. If you have a finished basement or the squeak is on your second floor, you will need to resort to top-down fixes.

  • Overview

    As precisely as you can, locate and diagnose the squeak. Then you can choose the best method to silence it. The problem could be the joists squeaking against the sub floor. Or possibly the bridging between the joists. You may need to resort to a top-down fix. Or possibly you need to tighten the strapping on ducts or pipes.

  • Locate Squeaks

    You need to first determine exactly where the squeak is coming from before you can take action. If the ceiling below is open and accessible, have a helper walk over the squeaky area while you watch and listen from below. Look for movement or flexing in the sub-floor or joists. Pinpoint the area the squeak is coming from. If the ceiling below is not open, have a helper walk around the squeaky area while you watch from floor level. Once you have diagnosed the problem, use the appropriate technique to remedy the situation.

  • Shim Under Arched Sub-floor

    If you can see a gap in between a joist and the sub-floor, use a straight edge to determine if the sub-floor is arching up or if the joist is sagging. If the sub-floor is arched up, take a wood shim, coat it with glue and tap it into the gap. Do not drive it in too tightly or you will cause other areas of the sub floor to pull away from the joist.

  • Brace a Sagging Joist

    If you determine that the floor joist is sagging and the sub-floor is lying flat, take a 2 x 4 and cut it so that it extends past the sagging area by at least ten inches in both directions. Using a long 2 x 4’s that you can wedge from the floor up to the ceiling to push the new support piece in place. Use a screw gun and three inch screws to secure the support piece to the joist.

  • Tighten Bridging

    If you determine that the squeak is coming from in between joists, the bridging in between your joists may be loose. Two common bridging techniques are solid bridging and crossed bridging. Make sure all of your bridging is secured tightly in place.

  • Add Bridging

    If the squeak persists, you may need to add some additional bridging in the squeaky area. Wedge a 2x6 in between the joists in the squeaky area. If the sub-floor is sagging, drive the sub-floor up with the new bridge. Using three inch screws, secure the new bridging to the joists. If the sub-floor is arched up above the new bridge, take a wood wedge coated with glue and tap it into the gap between the new bridge and the sub-floor.

  • Warped Floor Boards

    If you determine that the joists and sub-floor are not the culprits, your finished floor has probably warped and pulled away from the sub-floor. In the area of the squeak, drill pilot holes and use 1-1/4” screws to pull the finished floor snug against the sub-floor. Washers will help prevent the screw heads from pulling through the sub-floor.

  • Top-down Fixes

    If you cannot access the joists below the squeaky floor, you can probably solve the problem from the top down. First locate the squeak. Using ring-shank nails, drive them through the floor diagonally to hold down the loose flooring. If you have a hardwood floor, drill pilot holes to prevent splitting the wood. Use a nail set to sink the nail heads about 1/16” below the floor surface. Fill the nail holes with wood filler.

  • Tighten Straps on Ducts & Pipes

    If your squeak problem is caused by pipe or ducts rubbing against the joists, check to make sure all of their hangers are tight. If necessary, add additional hangers to secure the pipe or duct in the area where it is squeaking.
