How to Repair Leaky Glass Shower Enclosures

When my husband and I purchased our first home, the process was stressful, but we settled on one we liked enough to live in temporarily until we expanded our family. When moving time arrived, we both dreaded the expected stress. We ended up using a different real estate agent than we did the first time, and we made a great decision, because she had a lot of home remodeling knowledge! We were adamant on finally finding our "perfect" home this time. When she showed us homes that lacked features we desired that we would have "nixed" before, she let us know if the feature could be added, and usually it could! We are now in our new home that we had a few small renovations performed on after we bought it, and we love it! I want to help others by sharing some remodeling tips I learned on a blog!

How to Repair Leaky Glass Shower Enclosures

Glass shower doors look very stylish and make any bathroom seem classier and larger. However, they do need to be maintained and cleaned to ensure that they are waterproof. The most important and vulnerable part of a glass shower enclosure is the caulk where the glass meets the walls. The caulk line can harbor mold if it is not properly cleaned. It can also deteriorate to the point that the enclosure is no longer watertight. If your glass shower enclosure has leaky or moldy caulk lines, you will want to fix them as soon as possible. This article explains how to remove the old caulk and apply new lines.

Remove All the Old Caulk

First, you need to remove all of the mold and clean the edges of the glass. You also need to make sure the wall surface near the glass is clean and smooth. Use a scraping device like a putty knife to get most of the caulk off. You will then need to use a strong household cleaner or degreaser to fully clean the surfaces and get rid of all the residue. You also need to scrape out any caulk that is in between the wall and the glass. This is usually the area where mold will form if the glass is not cleaned frequently.

Apply the New Caulk

Now your enclosure will be ready for the new caulk. You will want to use a waterproof silicone caulk. Most people choose a clear caulk, but you can also use a solid color caulk that matches the wall color. But, before you apply it, you can use painters tape to create perfectly straight lines. Simply apply the tape to the wall on one side and the glass on the other. This allows you to also control the thickness of the caulk line and to make sure that it is even along the entire seam.

You will obviously need a caulk gun to first shoot it into the seams. Then, you can use your finger to spread the caulk and push it further in between the glass and the wall. You don't want any cavities underneath the caulk; it should be as dense as possible. Wiping the caulk with your finger will also create a line that is smoother.

As you can see, this simple job does not require any special tools or training; there's no need to call a handyman when you can easily do the work on your own. If you would like to install a new shower door, contact a company like South Jersey Glass & Door.
