In this video, This Old House general contractor Tom Silva explains how to fix a sticky shower door.


1 Use screwdriver to loosen the screws in each corner of the shower doorframe.
2 Loosen the screws holding the handle to the shower door.
3 Open the shower door and stand a 2x4 block underneath its outer, bottom corner.
4 Slide shims into the space between the 2x4 block and door.
5 Hold a wood block against bottom corner of door and tap upward with hammer.

9 If the door still sticks, loosen the screws and repeat the process.
