Washroom sealing in Yiewsley
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them.

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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Commercial washrooms in Yiewsley
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. The area within 2 miles of Yiewsley holds a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.
Where you’re responsible for a hall attached to a building such as St Joseph the Worker & Dovetail Centre, its kitchen and toilets need sealant that stays cleanable. Colleges such as Uxbridge College (to the south-west of Yiewsley) have toilets, changing rooms and catering kitchens that can be resealed around term dates. Halls of residence and teaching buildings at universities such as Brunel University of London, 3.5 miles to the west of Yiewsley, are easiest to reseal during vacations.

Why deal with it now?
Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. Failed sealant in a building in Yiewsley can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- How much existing material needs removing
- Access and working height
- Phasing around occupants
- Location, for remote and island sites
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Clear photos of the problem areas
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
For a fixed quote, call 01277 525 020 or email us. You can also send details through our quote form.
What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Failed tanking beneath a wet-room floor or behind tiles
- A dripping waste or valve behind a panel
- Condensation from failed extract fans
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Questions about Yiewsley
Is hospital work, at somewhere like Ealing Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do hotels near Yiewsley have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
Which silicone is right for commercial washrooms?
An anti-mould sanitary silicone for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Will all the toilets be closed at once?
The work is phased so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.
How soon can a washroom be used after resealing?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a job in Yiewsley, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We confirm reopening times for each washroom.
Preparing the site
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
