At some point or other most people have had to deal with a leaking shower door. The first indication that you have a problem is usually a puddle of water just outside the shower. You may not notice this immediately, since it could take a few minutes for it to collect after you exit the shower. If you find a leak, it's relatively easy to repair. The following will show you how to do this.

Things You Will Need

  • Razor knife
  • Towel
  • Duct tape
  • Needle
  • Caulking gun
  • Silicone caulk
  • Door seal (rubber)

Step 1. Use a towel to dry the bottom of the shower stall, particularly in the area around the shower drain. Then cover the shower drain with duct tape to keep any debris or old caulking that you remove from going down the drain.

Step 2. Check out the inside of your shower door to see if the frame has any old caulking material. Usually the builder will have applied caulking is a seal to keep water from leaking through the door. However, if the entire bottom section of the door frame has been sealed, it's possible for the drain holes that are there to become blocked, which can cause leaks from other parts of the door.

Step 3. Use a razor knife to scrape away as much of the old caulk from the doorframe as possible.

Step 4. Make sure that you find the drain holes and channels located at the bottom of the frame. Be certain you have removed any caulk covering them. Even then, it may be necessary to use a needle to pick out any caulk remaining in the holes and channels. Once you do this, the drain holes should work properly.

Step 5. Now examine the rubber seals along the outside of the doorframe. Pay particular attention to the one located at the bottom of the door. See if you notice any signs of cracking or wear. If you do, replace the seals.

Step 6. Use the razor knife to remove any old caulking material on the outside of the frame. Insert a tube of silicone caulk into a caulking gun and use it to replace the old caulk you just removed.

Note: Don't make the mistake of simply trying to cover over the old caulk with new caulk, since this won't work at all. If you would rather, have local plumbing services come to take care of the recaulking.
