Mr Mastic · South East, London and Scotland
Sealant contractors for hotels
Guest bathrooms, showers, spas and public washrooms resealed room by room, so housekeeping can keep selling rooms.
- Mouldy guest-room sealant
- Shower leaks into rooms below
- Room-by-room programmes
Why sealant matters in a hotel
Mouldy or split silicone is one of the first things a guest notices in a bathroom, and it can end up in reviews. A failed shower tray seal can also leak into the room or ceiling below, which takes rooms out of use for far longer than a reseal would. Keeping sealant in good order is quick, low-cost maintenance compared with either.
How we work in hotels
- We walk the site with you and agree the rooms, the order and the working hours.
- We work through rooms in batches, so only a few are out of use at any one time.
- In each room the old sealant is cut out completely, the joints cleaned, treated for mould and dried.
- New anti-fungal sanitary silicone is laid and tooled.
- Each room is handed back with its cure time, so housekeeping knows when it can be cleaned and let.
What we cover
- Guest bathrooms: baths, showers, basins, toilets and screens
- Accessible bathrooms and wet rooms
- Public and staff washrooms
- Spa, pool and changing areas
- Hotel kitchens and back-of-house areas
- Windows and outside joints
