How Long Does Silicone Sealant Last?

Most professionally applied silicone sealant can last many years, but its lifespan depends on the environment, usage, ventilation, and quality of installation.

Bathrooms, kitchens, and external joints are exposed to constant moisture, movement, temperature changes, and cleaning chemicals, all of which gradually wear sealant down over time.

Signs Sealant Is Starting to Fail

Common signs include:

  • mould growth
  • cracking
  • peeling edges
  • discolouration
  • gaps forming in joints
  • water leaks

These are often early indicators that sealant may no longer be providing effective waterproof protection.

 

What Causes Sealant to Deteriorate?

Sealant naturally ages, but several factors can shorten its lifespan:

  • poor ventilation
  • excessive moisture
  • movement in surfaces
  • harsh cleaning chemicals
  • low-quality materials
  • poor previous installation

Professionally applied sealant using quality materials generally performs far better over time.

    Excess silicone can squeeze out from the joints, making a mess and affecting the aesthetic. Apply just enough to cover the joint without overfilling.

  3. Skipping Surface Preparation
    Cleaning the surfaces before applying the sealant is crucial for proper adhesion. Don’t skip this step, as any dirt or residue can weaken the bond and cause the sealant to fail.

When to Consider Reapplying Silicone Sealant

While silicone sealant is durable, it does not last forever. Over time, it can degrade due to frequent exposure to water, cleaning products, and other environmental factors. Here are a few signs it’s time to replace your sealant:

  • Cracking or Peeling: If the sealant starts to crack, peel, or become discoloured, it’s a clear indication that it needs to be replaced.
  • Persistent Mould: If mould or mildew keeps growing despite regular cleaning, the sealant may no longer be doing its job effectively.
  • Water Leaks: If you notice water seeping through the joints, it’s time to reapply the silicone sealant.

Waterproofing your wet room with silicone sealant is a simple yet effective way to protect your space from water damage, mould, and mildew. By choosing the right product, applying it carefully, and maintaining it properly, you can ensure that your wet room stays dry and functional for years to come.

For the best results, always follow the manufacturer’s guidelines, and if you’re unsure, consider hiring a professional mastic man to apply the silicone for you. Their expertise will guarantee a high-quality finish, ensuring that your wet room remains waterproof and looking great.
