Washroom sealing in South Kensington, done properly
When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. If you are dealing with black mould inside silicone joints that cleaning can’t shift and open joints along basins and vanity units, we can help, whatever the surface. Facilities teams, main contractors and managing agents in South Kensington tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building managers in South Kensington normally need some facilities open throughout. We work through washrooms floor by floor or core by core, at times agreed with you.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

South Kensington: questions and answers
Will our hotel in South Kensington need to close for the work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Is a hospital such as The Royal Marsden Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Is it possible to just clean mouldy silicone?
Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.
When can showers be used after new sealant?
Each sealant has a cure time before it should get wet. We plan the phasing around that so facilities are never short.
Signs you need washroom sealing in South Kensington
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.
Most enquiries start with something like this:
- Sealant laid over old silicone and now peeling
- Discoloured joints around urinals and WC pans
- Failed sealant behind washroom basins
- Kitchen worktop joints that can’t be kept clean
At a hotel such as The Kensington Hotel, which lies north-west of South Kensington, the quieter weeks are the time to reseal bathrooms.
What your quote should include
- What level of public liability insurance do they hold?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint

What else we do in South Kensington
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Water from plumbing, not from a joint
- Leaks through tanking or membranes below the finishes
- Vanity carcasses that have swollen
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Surfaces we seal
- IPS panels and cubicles
- Urinals and WCs
- Vanity units and basins
- Kitchens and tea points
- Accessible toilets and changing rooms
- Showers, trays and wet room floors
After the work
After handover, a little attention goes a long way:
- Report split joints at trays and basins early
- Report faulty extraction promptly
- Keep washrooms out of use until we say the sealant has cured
- Include joints in routine washroom inspections
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, a routine look catches failing joints early.
Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
Keeping South Kensington washrooms open while we work
London offices and hotels normally can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager. A 2-mile radius around South Kensington takes in a good number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.
Staff changing rooms and patient toilets at places like The Royal Marsden Hospital, under half a mile east of South Kensington, need cleanable, sound silicone. For a store at a site such as Brompton Cross District Shopping Centre. (less than half a mile north-east of South Kensington), the staff room and customer toilets can be resealed in quiet periods.
South Kensington is about 1 mile south-east of Kensington, in Greater London. Any commercial site in South Kensington is covered. We work across 764 places in Greater London.
If you need washroom sealing in SW3, SW7 and SW10, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on King's Road, Fulham Road and Museum Lane. Being close to the A3217, South Kensington is straightforward for us to reach. Nearby places we also cover include Little Chelsea (1 mile south), Chelsea (1 mile east), Brompton (1 mile north-east), World's End (1 mile south) and Earl's Court (1 mile west). Further afield, our area takes in London (4 miles east), St Pancras (4 miles north-east), Shoreditch (5 miles north-east), Walthamstow (9 miles north-east), Hoxton (5 miles north-east) and Whitechapel (5 miles east).

Commercial clients in South Kensington
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Surface by surface
Wet-room floors and floor-to-wall joints
We seal the visible joints; we don’t install or repair waterproofing below, and we’ll say if the trouble looks to be beneath the floor.
Showers and trays
A tray flexes every time it’s used and is constantly wet. Tray joints are where many washroom leaks start.
How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in South Kensington can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- Joints are cleaned, degreased and dried before sealing.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- You get a reopening time for every room, with signage left up until then.
Getting the site ready
- Send your site hours and access windows
- Point out any areas we must not close
- Let us know about inductions and permits
