When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Loose panels, vanity units or tiles, which need fixing first
- Vanity carcasses that have swollen
- A dripping waste or valve behind a panel
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

How we handle washroom sealing in Barnsbury
In a commercial washroom, sealant is normally the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on urinals and WCs, accessible toilets and changing rooms and kitchens and tea points, and the failures we’re asked to look at most are sealant stained black around basins and showers and stained sealant around pans and urinals. Searching for sealant specialists in Barnsbury? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In a London area such as Barnsbury, commercial washrooms in offices, hotels and leisure buildings see constant use. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Site staff or a sealant specialist?
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Wet areas in Barnsbury’s workplaces
There are plenty of hotels within about 2 miles of Barnsbury. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest. The 2 miles around Barnsbury include three care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. We plan the work with the manager so residents are disturbed as little as possible.
Colleges such as City and Islington College, 0.9 miles north of Barnsbury, have toilets, changing rooms and catering kitchens that can be resealed around term dates. In a centre such as Brunswick Centre (1.4 miles south of Barnsbury), public washrooms are resealed a block of facilities at a time. For a campus such as University of the Arts London, which lies south-west of Barnsbury, showers in residences and washrooms in teaching blocks can be programmed around term dates.

Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Don’t leave trays and floors sitting wet
- Mention any site permits or estates rules at quote stage
- Inspect washroom sealant regularly
- Report split joints at trays and basins early
Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.
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.
Barnsbury: questions and answers
Do you take on jobs in Barnsbury where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do you take on work at healthcare sites like St. Pancras Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Which silicone is right for commercial washrooms?
An anti-mould sanitary silicone in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
