Commercial sealant in South Bermondsey, done properly
Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on hotel bathrooms, office washrooms & kitchens and retail & leisure sites, and people most often call us about tired sealant in let properties and failed floor-level joints in accessible wet rooms.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in South Bermondsey, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
Each job carries a 12-month guarantee, whatever its size.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes as long as the scope needs, from one welfare room to a full building, depending on the amount of work. In South Bermondsey, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- We clean the joints, treat any mould and let them dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Before we arrive
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

Leave it or put it right?
A quick bead over the old sealant might get a room back in use today, but it won’t bond, and it lifts again soon. One proper reseal beats several quick ones. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

It’s worth asking for a quote if you see:
- Water marks on ceilings under bathrooms
- Sealant failing again soon after quick repairs
- Washroom sealant that looks dirty however often it’s cleaned
- Split sealant where wet room floors meet walls
