A shower should keep water inside the enclosure. However, when silicone sealant begins to fail, water quickly finds its way into places it should never reach.
Across Belfast and Northern Ireland, many homeowners contact us because they notice mouldy sealant, peeling silicone or small leaks appearing around their shower trays. These signs almost always indicate that the silicone seal has reached the end of its life.
Fortunately, replacing shower silicone is a straightforward restoration when done correctly.
Why Shower Silicone Is So Important
Silicone sealant sits at the joints where water is most likely to escape. You will normally find it:
-
around shower trays
-
along the base of tiled walls
-
around glass shower enclosures
-
in corners where tiles meet
Because showers experience constant moisture, the silicone seal acts as a flexible waterproof barrier.
Over time, however, this barrier gradually weakens.
Signs Your Shower Silicone Needs Replacing
Homeowners often notice small warning signs long before serious leaks appear.
For example:
-
black mould forming along silicone lines
-
silicone peeling away from tiles
-
cracks appearing in the sealant
-
water escaping onto the bathroom floor
-
damp patches near the shower area
Once these problems appear, replacing the silicone quickly helps prevent water damage.
Why You Should Never Apply Silicone Over Old Sealant
A common DIY mistake involves applying fresh silicone directly over old sealant.
Unfortunately, this rarely lasts.
Old silicone prevents new sealant from bonding properly, which means the new seal will eventually lift away from the surface.
For this reason, professional silicone replacement always includes:
-
Removing all old sealant
-
Cleaning and preparing the surfaces
-
Drying the area fully
-
Applying new anti-fungal silicone
This process ensures a long-lasting waterproof seal.
