Washroom sealing for commercial buildings in City of Westminster
In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Tell us what records you need and we will confirm with the quote. If you’re dealing with resealing that didn’t last because the old bead stayed and sealant stained black around basins and showers, we can help, whatever the surface. Facilities teams, main contractors and managing agents in City of Westminster tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
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.

Building owners, agents and FMs in City of Westminster
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. In City of Westminster, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- The failed silicone is stripped and every face scraped clean of residue.
- We clean and dry every surface so the new sealant can grip.
- 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.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work

Advice
Questions we are asked in City of Westminster
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Could you schedule work at a campus like University of Westminster for the vacation?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is there a guarantee on the work?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Can you clean the mould off instead of resealing?
Usually not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Do you need to remove the old sealant?
We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Leave signs up until the cure time is over
- Note failing joints building by building
- Don’t leave an open joint at a basin or tray
- Inspect washroom sealant regularly
We hand each area back once the silicone has had the cure time the product needs. We will tell you when the wet areas can be used and signage stays in place until that time.
Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Surface by surface
Showers and trays
A tray that rocks or has cracked won’t be fixed by sealant and we flag that beforehand.
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.
Leave it or put it right?
Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. Failed sealant in a building in City of Westminster can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Wet areas in City of Westminster’s workplaces
City of Westminster has plenty of hotels close by, all within 2 miles. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. The work can go floor by floor, agreed with housekeeping. In London buildings, toilets and showers generally need to stay partly open, so we take one block of facilities out of use at a time.
Student showers at universities like University of Westminster, 0.7 miles to the north-east of City of Westminster, see more use than most, and their silicone shows it. Customer toilets in retail centres such as Brunswick Centre, 1.4 miles north-east of City of Westminster, rarely close, so resealing is phased. For a site such as The London Welbeck Hospital, which lies north-east of City of Westminster, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.
City of Westminster is about 3 miles west of London, in Greater London. We cover commercial sites throughout City of Westminster, whether it’s a single job or part of a planned programme. City of Westminster is one of 764 places in Greater London on our list.

Quoting for work in City of Westminster
The price varies from site to site. It mainly depends on:
- Whether old sealant has to be cut out first
- How accessible the joints are
- The size and state of each joint
- How much there is to seal
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

The more we know, the firmer the quote. When you get in touch, include:
