Leave it or put it right?
When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Failed sealant in a building in South Bermondsey can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Washroom sealing in South Bermondsey, done properly
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. If you are dealing with mould spotting along silicone joints and urinal joints that look unhygienic, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in South Bermondsey it comes down to the same thing: the right product in a properly prepared joint.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What else we do in South Bermondsey
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Common questions from South Bermondsey clients
Can you work around term dates at a campus such as Northeastern University London?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is a hospital such as Guy's Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
How long before the toilets can reopen?
The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so facilities are never short.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you reseal washrooms in healthcare buildings?
We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
Do you phase washroom resealing?
Just the room being resealed is out of use. Each room reopens after the sealant’s cure time, then we move on.
What’s the quickest route to a quote?

Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Tell us about infection-control or permit rules before we quote
- Leave signs up until the cure time is over
- Clean sealant with gentle products and a soft cloth
- Make sure washroom ventilation is running
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.
A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well, so reseal when you first spot a split.

Do you need washroom sealing in South Bermondsey?
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water, and they stain, crack or wash out.
Things that typically lead to an enquiry:
- Stained sealant around pans and urinals
- Black mould inside silicone joints that cleaning can’t shift
- Sealant laid over old silicone and now peeling
- Panel joints letting water behind
For an occupier at a site such as Bermondsey Trading Estate, which lies north-east of South Bermondsey, the canteen and welfare facilities need cleanable joints as much as any office.
Before you book anyone
- How joint depth will be controlled
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- What level of public liability insurance do they hold?
