There can be many reasons why your shower leaks. It is important to identify the root of the problem so that it can be fixed. If the source of the problem is not identified, it can go on to cause damage and weaken your home.
Here are some of the possible reasons why your shower is leaking:
How Can I Tell If My Shower is Leaking?
Moisture causes materials to weaken and degrade. If you smell mildew or rotting wood, there is a good chance that you have a leak somewhere.
Not only does moisture degrade materials, it can cause bubbles and gaps to form beneath paint. One sure sign of water damage is if your paint is showing signs of no longer adhering to the wall.
A water leak can cause a wall to warp or for water stains to appear where the damage is occurring.
As the moisture causes the grout to degrade or the wall to warp, grout can come loose and fall out of place.
Another sign of water damage is when tiles become loose, whether due to weakening adhesive or a warped surface where the tiles have been placed.
Wood, like many materials, expands when it is exposed to moisture. If your bathroom door gets stuck, this may be a sign that it is being exposed to excessive moisture.
What is the Source of My Shower Leak?
There can be any number of reasons that your shower is leaking. If you want to prevent the excess moisture from ruining the structure of your home, you need to find the source. The sooner the leak can be located and dealt with, the better.
The ground moves over time. It is very slow and subtle, but it happens. And, when it happens, it can cause buildings to shift, as well. When buildings shift, joints may come loose, cracks appear, floors may no longer be level and doors may no longer be square.
Materials, too, can change over time. Use and age can cause wood to warp or bow. Walls, too, may bow. When bowing, warping, twisting, thinning or any other degradation of materials, gaps may appear. Gaps allow in moisture which in turn can cause more damage.
Believe it or not, tile is not waterproof. Neither is grout or the backing board that the tile is mounted on. Each has its own degree of water permeability, but none is entirely waterproof.
There is a liquid waterproofing agent that can be used to coat some of your shower materials. If you use harsh chemicals when cleaning your shower, it can wear away at the waterproofer. It can also cause the shower materials to degrade.
Just as harsh chemicals can cause problems in you shower, so can using poor materials to begin. If quality materials were not used in the initial construction of your shower, you will pay for it later.
Some of the plumbing for your shower runs behind the wall. If a plumbing joint comes loose or springs a leak, it can cause water damage.
Tile, as mentioned above, is not entirely waterproof. Coating it with a sealer can help. But if the tiling is not set properly, it can permit water to get through and cause a leak.
