About our washroom sealing in Crayford
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. If you have stained sealant around pans and urinals and a new bead over an old one coming away, we can put it right. One point of contact handles commercial sealant work in Crayford from the first photos to the final walk-round, for single jobs and planned programmes alike.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for washrooms and wet areas
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- How much there is to seal
- Site requirements such as inductions and permits
- Joint width, depth and condition
- Phasing around occupants
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
However big the job, these details speed things up:
- The product your specification calls for
- Whether an asbestos survey exists
- The postcode of the building
- Anything awkward about access or site hours
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Busy facilities in and around Crayford
A London building with hundreds of occupants can’t lose every washroom for a day, so resealing goes floor by floor, agreed with the facilities team. Several hotels sit less than 2 miles from Crayford. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.
At a retail site such as Tower Retail Park, under half a mile to the north of Crayford, public and staff toilets see heavy use, so mouldy or split sealant is best replaced in phases. At a university such as University of Greenwich, which lies east of Crayford, summer is the usual window for resealing residence bathrooms.
Crayford is about 2 miles west of Dartford, in Greater London. We cover commercial sites throughout Crayford, whether it’s a single job or part of a planned programme.

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a morning or so for a small washroom, longer where showers and changing rooms are included, and we clear our waste as we work. In Crayford, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First, the phasing is agreed so facilities stay open.
- 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
- Warn occupants and staff about the work
- Point out parking and an unloading spot
- Let us know about inductions and permits

Common questions from Crayford clients
Can you work around term dates at a campus such as University of Greenwich?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Is Crayford in your area?
Yes. Crayford is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or send photos by email.
What sealant do you use in washrooms?
It depends on the joint. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.
How long does a typical visit take?
It depends on the scope, but the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
What we are called out for in Crayford
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.
Most enquiries start with one or more of the following:
- Mould spotting along silicone joints
- A new bead over an old one coming away
- Panel joints letting water behind
- Sealant lifting along a tray edge
At a hotel such as Bexleyheath Marriott Hotel (1.3 miles west of Crayford), the quieter weeks are the time to reseal bathrooms.
Before you book anyone
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
- Will CSCS-carded applicators be on site?
- How long is the guarantee, and what does it include?
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Looking after the joints
Regular inspection catches problems early. In particular:
- Don’t leave trays and floors sitting wet
- Add sealant joints to planned maintenance checks
- Report split joints at trays and basins early
- Keep extract fans working and vents clear
We hand each area back once the silicone has had the cure time the product needs. You’ll be told when showers and basins can be used again, and it helps if signs stay up until then.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
