Mold/Silverfish issues and how to rescue your shower?

Lately, we have been receiving an increasing amount of phone calls from customers complaining about mold, cracked or loose tile problems in their showers. Our customers are surprised that this is happening to them because their homes are relatively new, 3 to 7 years old.

Unfortunately, we are not at all surprised that our customers' showers are suffering from mold, silver fish, cracked or loose tiles. Here is why:

1. Most builder built showers have either the 4x4 or the 6x6 builder quality tiles.
2. These tiles are often tightly installed with the built-on spacer of the tiles.
3. Lack of space between the tiles means that limited amount of grout can be worked in between the tiles.
4. Furthermore, most of these tiles are directly installed on dry walls (regular or green) without the use of a vapor barrier layer or other protective materials.
5. Sealed or not, water eventually penetrates through the grout lines and completely soak up the dry wall behind the tiles.
6. This causes tiles to come loose, mold and silver fish to grow behind the walls.

Result is an unusable shower that is also a health risk to you and your family. Here is what Environmental Protection Agency writes about mold:

"Molds produce tiny spores to reproduce. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet, and foods. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or un-addressed. There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture."

Things you should know about mold problem and prevention:

1. Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints.

2. There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
   

3. If mold is a problem in your home or school, you must clean up the mold and eliminate sources of moisture.
4. Fix the source of the water problem or leak to prevent mold growth.
5. Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, that are moldy, may need to be replaced.
   
6. Molds can be found almost anywhere; they can grow on virtually any substance, providing moisture is present. There are molds that can grow on wood, paper, carpet, and foods.

Another nuisance found along with mold is Silverfish.

"Silverfish is about 1/2 inch long, with a uniform silvery color over the upper surface. Their bodies are long and slender, flattened. The bodies are broad at the front, and gradually tapering toward the rear.
They can be found almost anywhere, but prefer damp, moderate temperature places such as basements, laundry rooms, and under sinks.

• Silverfish prefer a dark, moist environment and require a large supply of starchy foods or molds.
  
• Silverfish are considered to be nuisance pests that can feed on wallpaper pastes, natural textiles, books, and papers.
  
• Silverfish also feed on mold or fungi that can grow on various surfaces.
  
• They are fast-moving and can travel throughout buildings.
  
• Silverfish can damage book bindings, wallpaper, paper goods and dry foods. They may eat holes, irregular shaped in the wallpaper to get to the paste.
• They may leave a yellowish stain on fabric."

As described above from official resources, mold and silverfish problem have serious health effects and require the elimination of sources for moisture. A1A Contractors have been eliminating the moisture problem by using a protective membrane layer between tiles and dry walls in the shower and bathroom areas.

Our choice for this protective layer is a product offered by Schluter Shower Systems.

This system completely seals off the walls and prevents any moisture from damaging the dry walls. This prevents mold and silver fish growth as well as preventing tiles from becoming loose and separated. Schluter Shower Systems is not the only product line available in the market, but it is one of the most advanced technologies for your shower and bath areas.

The idea is to eliminate the source of moisture to save your health and your shower.
