Washroom sealing in Marylebone, done properly
Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. If you have stained sealant around pans and urinals and sealant stained black around basins and showers, we can put it right. A single leaking joint is often how a building in Marylebone first comes to us: we look at the rest while we’re there and tell you what we find.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. 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 we finish is backed by a 12-month workmanship guarantee, in Marylebone as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Washroom sealing around Marylebone: points for this area
A 2-mile radius around Marylebone takes in a good number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest. In London buildings, toilets and showers generally need to stay partly open, which is why the work is split into phases agreed in advance.
At a retail site such as Brompton Cross District Shopping Centre. (1.9 miles south-west of Marylebone), public and staff toilets see heavy use, so mouldy or split sealant is best replaced in phases. Halls of residence and teaching buildings at universities such as University of Westminster, under half a mile north-east of Marylebone, are easiest to reseal during vacations.
Marylebone is about 3 miles north-west of London, in Greater London. We cover Marylebone and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Marylebone is one of 764 places in Greater London on our list.
If you need washroom sealing in W1U, W1T and W1K, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Park Lane, Duck Lane and Bruton Lane, and sites on any of them can send details for a fixed quote. Being close to the A400 and A401, Marylebone is straightforward for us to reach. If your building is just outside Marylebone, we cover City of Westminster (1 mile south-west), Mayfair (1 mile south), Fitzrovia (1 mile north-east), Burlington Estate (1 mile south-east) and Soho (1 mile south-east). Bigger towns within reach include London (3 miles south-east), Kensington (3 miles south-west), Shoreditch (3 miles east), Walthamstow (7 miles north-east), Hoxton (3 miles north-east) and Whitechapel (3 miles east). Marylebone is one of the busier places in Greater London, and its commercial and public buildings are all within our area.

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Loose panels, vanity units or tiles, which need fixing first
- Panel boards already damaged by water
If you’re not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer.

Do you need washroom sealing in Marylebone?
Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.
It’s worth sending us details if you spot any of the following:
- Shower tray joints that have opened up
- Open joints at the base of cubicle panels
- A new bead over an old one coming away
- Sealant stained black around basins and showers
Clinical washrooms at sites like The London Welbeck Hospital (to the west of Marylebone) are scheduled with the ward so the room is out of use for as little time as possible.
Before you book anyone
- Whether primer will be used where the manufacturer specifies it
- Their approach to joint depth and backing
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
What sets the cost
What shapes the price:
- Access and working height
- Backing rod, priming and other preparation
- The product specified
- Whether old sealant has to be cut out first
A quote for washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
Details that help us quote
A few photographs plus some basic facts will normally do. It helps to include:
- Approximate linear metres or a joint schedule
- The postcode of the building
- How the joints are reached, and at what height
- Clear photographs of the problem areas
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or use the quote form.
Leave it or put it right?
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. Getting scaffold, permits or access booked in Marylebone takes effort, so it makes sense to deal with every failing joint while access is in place.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
