Washroom sealing in Clapham Junction, done properly
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 there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. We work on showers, trays and wet room floors, vanity units and basins and accessible toilets and changing rooms, and what we are called in for most is users noticing mouldy joints and open joints at the base of cubicle panels. Most enquiries from Clapham Junction 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.
In a London area such as Clapham Junction, 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. In Clapham Junction, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- We agree which rooms close and when, so users always have somewhere to go.
- 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
- Let building users know which areas are affected
- Move anything stored against the joints
- Share the asbestos register for older buildings

Advice
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Condensation from failed extract fans
- A dripping waste or valve behind a panel
- Vanity carcasses that have swollen
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- IPS panels and cubicles
- Urinals and WCs
- Vanity units and basins
- Accessible toilets and changing rooms
- Showers, trays and wet room floors
- Kitchens and tea points
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

When to call us in Clapham Junction
A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old so it peels away quickly.
If one of these sounds familiar, it’s time for a closer look:
- Shower tray joints that have opened up
- Complaints from staff, guests or users about tired washrooms
- Discoloured joints around urinals and WC pans
- Failed sealant behind washroom basins
At a college such as South Thames College Wandsworth Campus, 1.1 miles to the south-west of Clapham Junction, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

Clapham Junction: questions and answers
Would you work within a site like Chelsea and Westminster Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does a hotel in Clapham Junction need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Do you use special sealant for toilets and showers?
An anti-mould sanitary silicone for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Will all the toilets be closed at once?
We phase it so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Is old silicone taken out first?
We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.
How the job changes by surface
IPS and cubicle panels
Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. We check fixings before sealing.
Urinals and WC pans
Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.
