Commercial & hotel sealant in Stone, Kent
Commercial sealant for Stone, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Tired sealant ahead of a health and safety audit
- Leaks from showers into rooms or ceilings below
- Repeated reseals that do not last
When something else is needed

- Cracked trays or baths rather than failed joints
- Fire risk assessments or certification
- Poor ventilation that keeps bringing mould back

Common problems we fix in Stone
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. Any split there can let water through quickly.
Common reasons people contact us are:
- Water marks on ceilings under bathrooms
- Black, stained silicone in guest bathrooms
- Split sealant around staff kitchen worktops and sinks
- Mouldy bathrooms flagged at a tenancy check
If you let a flat or house near Stone Crossing station, several rental properties can be resealed on one programme.

Leave it or put it right?
Sealing over the old bead can seem the fastest option, but it will not bond, and it lifts again soon. One proper reseal beats several quick ones. Homes in smaller places like Stone can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Note the date each area was done
- Pass on the cure time to whoever cleans the rooms
- Put a squeegee in each shower
- Keep strong chemicals and scourers off the joints
Squeegees in guest and staff showers help: less water sits on the joints between uses.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
