Washroom sealing in Chinatown
For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Any records you need are confirmed with the quote. Site teams most often ask us about discoloured joints around urinals and WC pans and open joints along basins and vanity units, across IPS panels and cubicles, showers, trays and wet room floors and urinals and WCs. A specialist sealant contractor works differently from a general builder: in Chinatown, that means joint design, primers and backing rod as standard.
Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Chinatown: questions and answers
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them.
Is a hospital such as Royal London Hospital for Integrated Medicine somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
How long before the toilets can reopen?
That varies with the sealant and the room temperature. You will get a reopening time for each area, and signs stay up until then.
Which sealant will you use?
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.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Washroom sealing around Chinatown: how the place shapes the job
London offices and hotels normally can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team. A 2-mile radius around Chinatown takes in a good number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.
Colleges such as Westminster Kingsway College Soho Centre, under half a mile north-west of Chinatown, have toilets, changing rooms and catering kitchens that can be resealed around term dates. Student showers at universities like University of Notre Dame, less than half a mile to the south of Chinatown, see more use than most, and their silicone shows it.
Chinatown is about 1 mile east of City of Westminster, in Greater London. Commercial clients in Chinatown use us for work on washrooms and wet areas, as part of our coverage of Greater London. Across Greater London, 764 places are covered, including Chinatown.
Postcode districts covered here: W1F, W1D and W1T. We cover commercial and managed buildings on Duck Lane, Drury Lane and Bruton Lane. Chinatown sits on or close to the A4 and A301, which helps when planning parking and deliveries for the job. We also cover Soho (1 mile north), St James's (1 mile south), West End (1 mile north-east), Seven Dials (1 mile north-east) and St Giles (1 mile north-east) for washrooms and wet areas. Nearby towns on our patch include Kensington (3 miles west), Shoreditch (3 miles north-east), Walthamstow (7 miles north-east), Hoxton (3 miles north-east), Whitechapel (3 miles east) and Hampstead (4 miles north-west).
What’s near Chinatown
In Chinatown, that means premises near LITE Regal International School, London Library and Waxy O'Connor's pub, among other places. Also close by are St Anne's Churchyard (less than half a mile north-west) and Harris Westminster Sixth Form (0.8 miles south). Chinatown has its own railway station: Tottenham Court Road station. Well-known places in the area include Leverian collection (under half a mile south-east) and Montfichet's Tower (1.3 miles east). Green spaces nearby include Barnsbury Wood and St. James's Park Lake.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- A phasing plan keeps part of the building’s facilities in use at all times.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Rooms reopen after the product’s cure time, and we move to the next.
Before we start on site
- Point out parking and an unloading spot
- Have the specification and drawings to hand
- Clear stock, furniture or equipment away from the joints

Advice
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
When to call us in Chinatown
Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We check for that first and say if it needs a plumber or another trade.
Things that usually lead to an enquiry:
- Sealant stained black around basins and showers
- Sealant laid over old silicone and now peeling
- Failed sealant behind washroom basins
- Split or peeling sealant at shower trays
Customer toilets in retail centres such as Brunswick Centre (to the north of Chinatown) rarely close, so resealing is phased.
What your quote should include
- How the existing material will be dealt with
- Proof of insurance
- Can the work be phased to keep areas open?
- Whether primer will be used where the manufacturer specifies it
Owners, agents and contractors
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Different surfaces, different methods
Urinals and WC pans
Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and make the room look neglected.
Wet-room floors and floor-to-wall joints
Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.
Looking after the joints
To get the most from the new sealant:
- Act on the first split you see at a shower tray
- Keep extract fans working and vents clear
- Share your site rules when you send details
- Photograph and log failed joints across the estate
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface and give mould a start.
Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.
