Silicone removal & replacement services

Silicone sealant is essential for keeping water out and preventing damage. It acts as a waterproof seal between walls and floors, allowing for building movement while protecting your tiles from cracks and leaks.

Over time, silicone deteriorates, leading to peeling, mould growth, and water seepage. If your shower sealant is peeling or you notice gaps where water can escape, it’s time for professional silicone removal and replacement.

At GroutPro, we specialise in removing old silicone sealants and applying new, high-quality sealants that are mould-resistant, eco-friendly, and available in a range of colours. Whether you need to reseal your shower or replace old, damaged silicone throughout your home, we’ve got you covered.

Mouldy silicone replacement in a shower

The warm, damp conditions in a shower create a breeding ground for mould and unless you dry the enclosure after every shower it will inevitable start to show up in the silicone and grout.

There is little you can do to stop it, and just have to face the fact that the silicone requires replacement every couple of years.

Groutpro are specialists and removing and replacing silicone.

Peeling Silicone around a kitchen splashback

Silicone in areas that are cleaned regularly, or are subjected to movement, can start to peel away, requiring replacement.

Silicone expansion joints

Large areas of tiled flooring, or concrete slabs, should have expansion control joints to allow for thermal expansion of the surface. This is often achieved with a bead of silicone.

GroutPro specialises in the installation of silicone in all applications.

    FAQ

    • How do I know my silicone needs replacement?

      If you notice peeling, cracks, mould stains, or gaps in your shower sealant, it’s time for a professional silicone replacement. Worn-out silicone can lead to water leaks, structural damage, and costly repairs if left untreated.

    • How do I replace the silicone in my shower?

      Silicone sealant creates a flexible, waterproof joint between tiles, walls, and glass panels in showers. Over time, it breaks down, peels, or grows mould, especially in high-moisture areas. Typically, silicone may last a couple of years in a new shower but needs to be replaced regularly in older showers.

      Removing and replacing silicone is a specialist job requiring sharp blades and precision. If not done correctly, it can damage waterproofing membranes or scratch surfaces. GroutPro replaces dozens of showers’ worth of silicone every day, ensuring a clean, professional finish.

    • How long does silicone stay mould free in a shower?

      The lifespan of mould-free silicone depends on daily maintenance. Moisture, heat, and soap residue create the perfect conditions for mould growth. To reduce mould buildup, we recommend:

      • Use a good, energy-efficient extractor fan while showering.
      • Wipe down your shower after each use to remove excess moisture.

      A brand-new shower with clean, dry conditions can stay mould-free for years, but as moisture builds behind tiles over time, mould spores can spread beneath the silicone. This growth means that subsequent silicone replacements may not last as long as the original installation. On average, shower silicone should be replaced every two years, but some bathrooms may need more frequent attention.
