Why This Matters

Old, leaking silicone around showers or wet areas can lead to hidden water damage, mould growth, and structural issues behind walls and floors. Over time, silicone breaks down, loses flexibility, and separates from surfaces, allowing water to seep through. Replacing deteriorated silicone is a simple but crucial step in maintaining a watertight seal, preventing costly damage, and keeping your bathroom hygienic and looking fresh. Regular maintenance ensures long-term protection and peace of mind. View Full Repair Guide and Tips

Silicone Failure & Water Ingress – FAQs

Understanding how failed silicone leads to hidden damage and how to stop it.

Over time, silicone loses flexibility, detaches from surfaces, or degrades due to mold and cleaning chemicals. This allows water to seep behind tiles, often going unnoticed until serious moisture damage occurs.

We remove old silicone and treat the area with antifungal agents. The cavity is dried thoroughly over several days, then resealed using high-performance, mold-resistant waterproof silicone.

Resealing prevents water from entering hidden cavities, which helps avoid mold, rot, and structural damage. Regular silicone maintenance extends the life of your bathroom and prevents expensive repairs.
