Washroom sealing in Millbank, done properly
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 have resealing that didn’t last because the old bead stayed and open joints at the base of cubicle panels, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Millbank, preparation and product choice get the time they need.
In a London area such as Millbank, commercial washrooms in offices, hotels and leisure buildings see constant use. 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.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

FAQs: Millbank
Is a hospital such as Gordon Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Must a hotel around Millbank close while you work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
Do you do washroom sealing in healthcare settings?
Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote.
Do you offer coloured sealant?
It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Is there a guarantee on the work?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or send photos by email. Include photos or drawings if you have them.
Is it OK to put new silicone on top of the old?
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.
Surface by surface
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.
Healthcare and care settings
We phase washroom sealing so care areas are never left without facilities. Tell us what records you need and we’ll confirm with the quote.
Keeping Millbank washrooms open while we work
Millbank has a good number of hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. Rooms are done in turn so most stay available. London offices and hotels typically can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager.
For a college such as Westminster Kingsway College, under half a mile to the south of Millbank, half-term and summer give the windows for washroom work. En suites at hotels like St. Ermin's Hotel, less than half a mile to the south-west of Millbank, are cleaned daily, which wears silicone over time.
Millbank is about 1 mile south-east of City of Westminster, in Greater London. We cover commercial sites throughout Millbank. We work across 764 places in Greater London.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Quoting for work in Millbank
To price the job, we consider:
- Travel to remote or island sites
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Access details, including height
- What the building is and how it’s used
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Why act early in Millbank
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. In a London building, a failed joint rarely affects only one party: 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.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. All of Greater London is in the ULEZ, and kerbside space in Millbank can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- We agree which rooms close and when, so users always have somewhere to go.
- 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.
What we need from you
- Move anything stored against the joints
- Have the specification and drawings to hand
- Let us know about inductions and permits

When to call us in Millbank
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
These are often picked up first by site or facilities staff:
- Split or peeling sealant at shower trays
- Users noticing mouldy joints
- Panel joints letting water behind
- Failed sealant in a tea point or staff kitchen
If you manage an office at a site such as Handel Business Centre, which lies south of Millbank, the washrooms and tea points can be done a floor at a time.
