The best shower seals for doors will keep this space watertight. Yet understandably over time and indeed use, shower seals will need replacing. By replacing shower door seals, this area of the bathroom can be kept in a healthy condition, while ensuring the space outside of the shower remains dry.
City Plumbing offers a variety of shower seal brands to help you get the best choice for your customers. Here we take a quick look at the tell-tale signs these seals need replacing, offer maintenance tips, and highlight just a few of our best-selling shower seals. 

How Often Should Shower Seals Be Replaced?

For best practice, shower seals should be replaced every one to two years. This will ensure that they continue to function correctly. Yet, understandably, this timeline can vary depending on factors such as the quality of the seals used, the frequency of shower use, and the type of cleaning products customers use in their shower.

Signs of a Leaky Shower Seal

Leaky shower seals can be a major headache for homeowners, leading to water damage, mould growth, and costly repairs. Here are several signs to look out for: 
Water Stains: One of the most obvious signs of a leaky shower seal is when homeowners spot the appearance of water stains. These are usually prevalent on the walls or ceiling near the shower. Water stains often appear as discoloured patches or streaks, yet they’re a clear indication that water is escaping from the shower enclosure.
Mould and Mildew: Another common sign of a leaky shower seal is the visible presence or smell of mould or mildew in the bathroom. If customers notice a musty odour or see black or green patches of mould growing in the corners or crevices of their shower, it may be due to a leaky seal.
Deterioration of Caulking: The caulking around a shower enclosure plays a critical role in keeping water out. So, if homeowners are beginning to notice that this is cracking, crumbling, or peeling away, it may be a sign that water is leaking through the seal.
Loose Tiles: Over time, water leaking from a shower seal can cause the surrounding tiles to become loose or detached from the wall. If customers notice tiles in the shower area are moving or shifting, it could be a sign that water has compromised the integrity of the seal behind them.
Soggy or Warped Baseboards: If a shower seal is leaking, water could seep into the walls and cause the baseboards to become soggy or warped. If homeowners notice that the baseboards near their shower are soft to the touch or have a warped appearance, it could be a sign of a leak.
Increased Water Bills: Finally, a leaky shower seal can also lead to a significant amount of water loss over time, meaning higher than usual water bills. If customers notice a sudden increase in their water usage without any clear explanation, this could be another indicator.

Help Customers Maintain Shower Seals

Though shower seals can be replaced, it’s a good idea to work on prolonging the life of them to prevent water damage. There are several simple maintenance tips that homeowners can follow, including:
  • Regular Cleaning: Cleaning shower seals regularly with mild soap and water will help to remove grime and prevent mould growth.
  • Avoiding Harsh Chemicals: Harsh cleaning products can break down the seals over time, so only gentle cleaners should be used here to preserve their integrity.
  • Checking for Wear and Tear: Inspecting shower seals periodically for any signs of wear and tear will help a homeowner become aware of any signs indicating the time to replace them as needed, thus preventing any leaks.
  • Keeping the Area Dry: After showering, homeowners should ideally wipe down the seals and surrounding areas to prevent moisture build-up.
