Washroom sealing in Cotman's Ash
Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you’re dealing with a new bead over an old one coming away and failed joints along IPS and cubicle panels, we can help. Most enquiries from Cotman's Ash start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Halls and community buildings near places like Cotman's Ash are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

After the work
To get the most from the new sealant:
- Clean sealant with gentle products and a soft cloth
- Act on the first split you see at a shower tray
- Mention any site permits or estates rules at quote stage
- Note failing joints building by building
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.
Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.
Why act early in Cotman's Ash
Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Halls, stores and units around places like Cotman's Ash may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Cotman's Ash: questions and answers
Would you work within a site like Sevenoaks Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Must every washroom in our Cotman's Ash building shut while you work?
Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is old silicone taken out first?
We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.
