Washroom sealing in Southwark, done properly
In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Tell us what records you need and we will confirm with the quote. If you’re dealing with sealant laid over old silicone and now peeling and failed sealant in a tea point or staff kitchen, we can help. One point of contact handles commercial sealant work in Southwark from the first photos to the final walk-round, whether it’s one building or several.
Many London buildings can’t close every toilet at once. 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.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Owners, agents and contractors
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Southwark can form part of a wider programme across Greater London.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep a record of which washrooms need attention
- Clean sealant with gentle products and a soft cloth
- Tell us about infection-control or permit rules before we quote
- Report split joints at trays and basins early
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.
Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.
Different surfaces, different methods
Changing rooms and gyms
We phase work so not every changing area is closed at once. Tell us your site hours and access windows and we will plan around them.
Showers and trays
In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Each bead is stripped, the joint dried and new sealant laid.
Sanitary sealant for Southwark buildings
Busy London buildings need some toilets open at all times, which is why the work is split into phases agreed in advance. Two care or nursing homes sit less than 2 miles from Southwark. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs.
If you manage an office at a site such as Southwark Bridge Business Centre (less than half a mile north of Southwark), the washrooms and tea points can be done a floor at a time. Toilets at places like Southernwood Retail Park, 1.3 miles to the south-east of Southwark, are cleaned constantly, so silicone needs to be sound and smooth.
Southwark is about 0 miles north-west of London, in Greater London. Businesses, contractors and managing agents in Southwark use us for work on washrooms and wet areas, as part of our coverage of Greater London. 764 places across Greater London fall within our area, including Southwark.
If you need washroom sealing in SE1 and SE11, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Borough Square, Trinity Church Square and Merrick Square are within our area. Southwark sits on or close to the A300 and B240, which helps when planning parking and deliveries for the job. Just outside Southwark, we also work in Tower Hill (1 mile north-east), City of London (1 mile north), Aldgate (1 mile north-east), Bishopsgate (1 mile north-east) and Barbican Estate (1 mile north). Further afield, our area takes in City of Westminster (3 miles west), Kensington (5 miles west), Walthamstow (7 miles north-east), Hampstead (5 miles north-west), Ruislip (14 miles west) and Brompton (3 miles west).

Questions about Southwark
Can you work around term dates at a campus such as London South Bank University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
How do I request a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a morning or so for a small washroom, longer where showers and changing rooms are included. All of Greater London is in the ULEZ, and kerbside space in Southwark can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Old sealant is stripped and the faces prepared.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Preparing the site
- Point out parking and an unloading spot
- Have the specification and drawings to hand
- Make sure the joints can be reached
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email us.
Advice
Signs you need washroom sealing in Southwark
Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
Typical triggers for a call:
- A new bead over an old one coming away
- Gaps where vanity tops meet the wall
- Stained or open joints at kitchen sinks and worktops
- Users noticing mouldy joints
Halls of residence and teaching buildings at universities such as London South Bank University (less than half a mile south-west of Southwark) are easiest to reseal during vacations.
Comparing quotes
- Proof of insurance
- What the guarantee covers, and for how long
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether their applicators hold CSCS cards
How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Whether old sealant has to be cut out first
- Distance, for remote addresses
- Phasing around occupants
- The site’s rules and procedures
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
- The type of building and who uses it
- Any dates the work must fit around
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
