Washroom sealing for Stone Street sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Why deal with it now?
Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. One visit to deal with every failing joint makes more sense than several trips to a place like Stone Street, rather than one at a time. Photos of every joint help us quote for the whole job.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Washroom sealing around Stone Street: what changes locally
At about 22 miles from central London, Stone Street is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.
For a school such as St Lawrence Church of England Primary School, washroom and kitchen sealant can be renewed around term dates. Church halls and community buildings, such as those at St Lawrence, have kitchens and toilets used by many groups, and their sanitary sealant works hard.
Stone Street is about 3 miles east of Sevenoaks, in Kent. Our applicators travel to Stone Street for work on washrooms and wet areas. We work across 931 places in Kent, large and small. For work in that direction, see our London page.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Different surfaces, different methods
Wet-room floors and floor-to-wall joints
Changing rooms and accessible showers often have wet floors so the edges are checked carefully.
Basins and vanity tops
A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.

Common questions from Stone Street clients
Would you work within a site like Cygnet Hospital Godden Green?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Will all the washrooms in our Stone Street building be closed at once?
Usually only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you phase washroom resealing?
We phase it so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.
Is old silicone taken out first?
The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.
Is Stone Street in your area?
Yes. We cover Stone Street, and the simplest way to start is to phone 01277 525 020 or email us.

Advice
What we are called out for in Stone Street
Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.
What tends to prompt an enquiry:
- Failed joints along IPS and cubicle panels
- Washrooms that look worn because of the sealant
- Failed sealant in a tea point or staff kitchen
- Resealing that didn’t last because the old bead stayed
Clinical washrooms at sites like Cygnet Hospital Godden Green, 1 mile to the west of Stone Street, are scheduled with the ward so the room is out of use for as little time as possible.
