Is your old or cracked silicone putting your bathroom at risk of water damage? As you know, when silicone gets damaged, cracked, or mouldy, it can leak or cause damage. In Darwin, our services include professional silicone replacements to provide waterproofing protection for showers, sinks, windows, and tiles. At Nova Tiles and Grout, we use products that remove old, worn-out silicone and high-quality, mould-free silicone sealants that are resistant to humidity and daily use to give it a clean look and provide lasting protection.
Silicone plays a critical role in waterproofing bathrooms, kitchens, and other moisture-prone areas. Over time, silicone can crack, shrink, or develop mould due to constant exposure to water and humidity. When it occurs, the water may creep behind tiles or fixtures, and this may result in structural damage, unpleasant odours, and expensive repairs. By replacing old silicone, a watertight seal is achieved, moulds are avoided, hygiene is improved, and your space, in general, is made presentable. Professional use guarantees good finishes, good adhesion, and durability long enough to match the climatic conditions of Darwin.
Our silicone replacement process is designed to ensure long-lasting waterproof protection and a professional finish. We carefully remove deteriorated sealant, prepare surfaces thoroughly, and apply premium mould-resistant silicone suitable for wet areas and external joints. Each step is completed with precision to prevent future cracking or leakage.
We review the available silicone, inspect for water damage, mould, and gaps, and determine the extent of replacement.
All damaged or mouldy silicone is carefully removed using professional tools to prevent surface damage.

Due to old age, exposure to moisture, improper application, or low-quality silicone, bathroom silicone can peel. Gradually, it will deteriorate due to environmental factors and wear.
Although the replacement of silicone can be done by DIY, this is not always advisable. Professional replacement is also related to proper preparation of the surface, solid seal and prolonged outcomes with no issues of peeling or destruction by water.
High-moisture silicone is usually replaced after 2-5 years, depending on the wear, exposure and environmental factors. Look at the presence of any damage such as cracks, peels or moulds.

The indications of silicone replacement that can be noticed are visible cracks, peeling, mould growth or water leaks around sinks, showers, and bathtubs. When silicone is no longer waterproof, then it is time to change it.
