The Mastic King
Kent's mastic sealant specialist
Bathroom & Shower Resealing in Kent
Mouldy, cracked or discoloured sealant? We remove it completely and replace it with a fresh, professional finish — most jobs done in 2–3 hours.
Why it matters
Mouldy sealant isn't just unsightly — it's a water damage risk
Once sealant starts to crack or go black, water gets behind your tiles. Left untreated, that leads to damp, damaged walls and costly repairs that dwarf the price of a simple reseal.
The Mastic King removes the old sealant entirely — no painting over it, no quick fixes — and replaces it with a clean, mould-resistant bead that looks great and lasts for years.
- Complete removal of old sealant and mould
- Surface preparation and thorough drying
- Professional-grade mould-resistant silicone
- Neat, consistent bead every time
