Washroom sealing in Crooked Billet, done properly
Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you have failed sealant behind washroom basins and stained sealant around pans and urinals, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Crooked Billet tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Many London buildings can’t close every toilet at once. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What happens if it’s left?
A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Report split joints at trays and basins early
- Clear standing water from shower floors where possible
- Keep washrooms out of use until we say the sealant has cured
- Tell us about infection-control or permit rules before we quote
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. 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. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We survey each room, count the joints and note anything behind them that needs another trade.
- 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.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- 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
- Point out parking and an unloading spot
- Agree which areas must stay open
- Confirm the product named in the specification

Advice
Common problems we fix in Crooked Billet
Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.
Things that normally lead to an enquiry:
- Users noticing mouldy joints
- Failed sealant behind washroom basins
- Black mould inside silicone joints that cleaning can’t shift
- Urinal joints that look unhygienic
For an occupier at a site such as Rainbow Industrial Estate, 1 mile south of Crooked Billet, the canteen and welfare facilities need cleanable joints as much as any office.
What your quote should include
- How long is the guarantee, and what does it include?
- How they handle RAMS and site documents
- How the joint faces will be prepared and primed
- Whether their applicators hold CSCS cards
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Removal of failed or old sealant
- The total length or number of joints
- The product specified
- Distance, for remote addresses
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Any specification or named product
- How the joints are reached, and at what height
- Where the site is, with the postcode
- A wide shot and a close-up of the area
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or send details through our quote form if you’d rather talk the job through.
Different surfaces, different methods
Kitchens and tea points
Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.
Basins and vanity tops
Vanity tops and basins are splashed all day, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.
Questions we’re asked in Crooked Billet
Do you work in occupied care homes around Crooked Billet?
Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.
Do hotels near Crooked Billet have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Do you cover Crooked Billet?
Yes. Crooked Billet is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, speak to us on 01277 525 020 or email a schedule or drawings.
Is it possible to just clean mouldy silicone?
Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
