Washroom sealing in Mayfair
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we will plan around them. Most enquiries involve discoloured joints around urinals and WC pans and kitchen worktop joints that can’t be kept clean, across showers, trays and wet room floors, kitchens and tea points and accessible toilets and changing rooms. A single leaking joint is often how a building in Mayfair first comes to us: we look at the rest while we are there and tell you what we find.
In Mayfair, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Inspect washroom sealant regularly
- Don’t leave an open joint at a basin or tray
- Don’t leave trays and floors sitting wet
- Brief cleaning staff to treat joints gently
Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well, so reseal when you first spot a split.
What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Water escaping beneath the floor rather than through a joint
- Loose panels, vanity units or tiles, which need fixing first
- Mould caused by poor ventilation, which will return until the extract is fixed
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.

Surface by surface
Changing rooms and gyms
Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we will plan around them.
Kitchens and tea points
Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sealed joints leave no gaps for food and dirt.

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Quantities, in metres or numbers
- Distance, for remote addresses
- Whether old sealant has to be cut out first
- Access and working height
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- The type of building and who uses it
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or email a schedule or drawings.
Your questions answered
Do you take on jobs in Mayfair where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Do hotels near Mayfair have to close for sealant work?
Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What do you charge?
There isn’t a price list, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Busy facilities in and around Mayfair
The area within 2 miles of Mayfair holds plenty of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. 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.
Colleges such as London College of Fashion (to the north-east of Mayfair) have toilets, changing rooms and catering kitchens that can be resealed around term dates. Healthcare estates like The London Welbeck Hospital (0.6 miles north of Mayfair) expect contractors to follow their permits and cleaning rules in every washroom. For a store at a site such as Brompton Cross District Shopping Centre., 1.4 miles to the south-west of Mayfair, the staff room and customer toilets can be resealed in quiet periods.
Mayfair is about 1 mile south-east of City of Westminster, in Greater London. Anywhere in W1K, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Mayfair is one of 764 places in Greater London on our list for washrooms and wet areas.

How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. In Mayfair, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. 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.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- 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.
Before we start on site
- Tell us your opening times and when work is allowed
- Send asbestos survey details if the building is pre-2000
- Confirm the product named in the specification

Why deal with it now?
Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. 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. Dealing with it early is simpler for everyone.
