Washroom sealing in New Addington: the local picture
A London building with hundreds of occupants can’t lose every washroom for a day, so we phase the work core by core or floor by floor with the building manager. A 2-mile radius around New Addington takes in several hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.
For a hall at a building such as St Edward King and Confessor, resealing the kitchen and toilets can be fitted between bookings. Colleges such as John Ruskin College, 1.3 miles north-west of New Addington, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Washroom sealing for commercial buildings in New Addington
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you’re dealing with urinal joints that look unhygienic and failed joints along IPS and cubicle panels, we can help. Most enquiries from New Addington 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.
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.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
Getting the site ready
- Let building users know which areas are affected
- Share the asbestos register for older buildings
- Have the specification and drawings to hand
Getting a fixed quote

Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Why act early in New Addington
Washrooms shape how visitors judge a building. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
A quote for washrooms and wet areas depends on quantities, condition and access. Ask us for a fixed quote.
Why appoint us
- Specification-led, product-correct work
- Clear, fixed quotes
- Standard and matched colours in many product ranges
- 12-month guarantee on workmanship

Your questions answered
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do hotels near New Addington have to close for sealant work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.
Is it OK to put new silicone on top of the old?
We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
What sealant do you use in 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 work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
When to call us in New Addington
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.
Most enquiries start with something like this:
- Panel joints letting water behind
- Sealant stained black around basins and showers
- Users noticing mouldy joints
- Stained sealant around pans and urinals
Pupil toilets at schools like Rowdown Primary School take heavy daily use, and the holidays give the window to reseal.
Questions to ask before you book
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with
- How long is the guarantee, and what does it include?
- How they’ll work around occupants
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Failed tanking beneath a wet-room floor or behind tiles
- A room that stays damp because ventilation isn’t working
- A dripping waste or valve behind a panel
If in doubt, ring 01277 525 020 or email the details over and we will say what we think.
Joints and surfaces we work on
- Urinals and WCs
- Accessible toilets and changing rooms
- Showers, trays and wet room floors
- Vanity units and basins
- IPS panels and cubicles
- Kitchens and tea points
Aftercare for building managers
To get the most from the new sealant:
- Clean sealant with gentle products and a soft cloth
- Clear standing water from shower floors where possible
- Keep washrooms out of use until we say the sealant has cured
- Act on the first split you see at a shower tray
Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.
Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
