Washroom sealing in Blackfriars, done properly
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on vanity units and basins, kitchens and tea points and accessible toilets and changing rooms, and what we are called in for most is open joints along basins and vanity units and resealing that didn’t last because the old bead stayed. Most enquiries from Blackfriars start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Building managers in Blackfriars usually need some facilities open throughout. 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.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. In Blackfriars, 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.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- You get a reopening time for every room, with signage left up until then.
Before we start on site
- Agree which areas must stay open
- Warn occupants and staff about the work
- Share your working hours and any access restrictions

Busy facilities in and around Blackfriars
There are plenty of hotels within about 2 miles of Blackfriars. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest. London offices and hotels normally can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team.
Healthcare washrooms on sites such as St Bartholomew's Hospital, less than half a mile north-east of Blackfriars, are resealed area by area, under the site’s own infection-control rules. Customer toilets in retail centres such as Brunswick Centre (1.2 miles north-west of Blackfriars) rarely close, so resealing is phased.
Blackfriars is about 1 mile north-west of London, in City of London. Across the SE1 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our City of London coverage takes in 7 places, large and small.
Business premises anywhere in SE1, EC1M and EC1N are within our area. Among the streets we cover are Oat Lane, Bear Lane and Shoe Lane. You will find Blackfriars on or near the A4 and A40. Nearby places we also cover include Temple (1 mile west), Temple Bar (1 mile west), Bankside (1 mile south-east), Smithfield (1 mile north) and Clare Market (1 mile west) for washrooms and wet areas.
Landmarks near Blackfriars
Locally, jobs take us to sites close to The Black Friar pub, Bernie Spain Gardens and London Nautical School, among other places. Nearby too are St Alban's Church of England Primary School (0.6 miles north-west), Barts Health Archives (under half a mile north-east) and St Mary-at-Hill (0.9 miles east). There’s a railway station in Blackfriars itself: London Blackfriars station. A little further out are Montfichet's Tower (less than half a mile north-east) and St Brides Crypt Museum (under half a mile north-west). For a walk, there’s St. James's Park Lake and Ludgate Hill.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Vanity carcasses that have swollen
- Loose panels, vanity units or tiles, which need fixing first
- A room that stays damp because ventilation isn’t working
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.

Your questions answered
Does a hotel in Blackfriars need to shut while its sealant is renewed?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Do you take on work at healthcare sites like St Bartholomew's Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
What guarantee comes with washroom resealing?
A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
What will the job cost?
Each job is quoted on its own details. To get one, give us a call on 01277 525 020 or send details through our quote form with a description of the work.
Do you work in Blackfriars?
Yes. We cover Blackfriars, and you can speak to us on 01277 525 020 or use the quote form to get started.
Why deal with it now?
A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we’re called out for in Blackfriars
Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.
Common reasons buildings call us in:
- Black mould inside silicone joints that cleaning can’t shift
- Sealant laid over old silicone and now peeling
- Stained or open joints at kitchen sinks and worktops
- Open joints along basins and vanity units
Welfare facilities in units on estates such as Grand Vitesse Industrial Estate (to the south of Blackfriars) have showers, toilets and kitchens with sealant that works hard.
