Why Kitchen Sink Silicone Fails and How to Prevent Water Damage
Many homeowners don't think about the silicone around their kitchen sink until a problem appears. However, damaged or worn silicone can allow water to seep beneath benchtops and cabinets, leading to expensive repairs and hidden water damage.
What Causes Kitchen Sink Silicone to Fail?
Kitchen silicone is exposed to daily use, water, cleaning products, and temperature changes. Over time, these factors can weaken the seal and reduce its effectiveness.
Common causes include:
Ageing silicone
Poor installation
Constant water exposure
Harsh cleaning chemicals
Movement of the sink or benchtop
Signs Your Kitchen Silicone Needs Replacing
You may need new silicone if you notice:
Cracks or gaps around the sink
Peeling or lifting silicone
Water leaking beneath the sink
Mould or staining around the seal
Loose sections of silicone
These issues can allow moisture to reach cabinets, walls, and benchtops.
Why Ignoring Damaged Silicone Can Be Expensive
A small gap in kitchen silicone may not seem serious, but over time water can cause:
Swollen cabinets
Damaged benchtops
Mould growth
Unpleasant odours
Costly repairs
Replacing silicone early is often much cheaper than repairing water damage later.

Complete removal of old silicone
Clean, straight finishes
Strong waterproof protection
Long-lasting results
