Frequently asked questions
Why does kitchen silicone need replacing?
Kitchen silicone is exposed to heat, moisture, grease and cleaning products daily. Over time it discolours, cracks and can harbour mould — a fresh seal makes a huge difference to both hygiene and appearance.
Can you match the silicone to my kitchen colour scheme?
Yes — we carry a range of colours including white, cream, grey, black and clear. We'll match as closely as possible to your existing kitchen finish.
Do you seal around undermount sinks?
Absolutely. Undermount sinks are a common job for us — we seal the joint between the sink and worktop to prevent water getting underneath and causing damage.
How long does kitchen sealing take?
Most kitchen sealing jobs are completed in 1–2 hours. We'll give you a clear timeframe when we provide your quote.
