Washroom sealing in Addiscombe, done properly
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. Replacing the bead is the lasting treatment. Most enquiries involve users noticing mouldy joints and sealant stained black around basins and showers, across showers, trays and wet room floors, urinals and WCs and accessible toilets and changing rooms. A single leaking joint is often how a building in Addiscombe first comes to us: we look at the rest while we’re there and tell you what we find.
In Addiscombe, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
The 12-month guarantee is for workmanship rather than 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.

Wet areas in Addiscombe’s workplaces
Addiscombe has a good number of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. A London building with hundreds of occupants can’t lose every washroom for a day, so resealing goes floor by floor, agreed with the facilities team.
Toilets at colleges like Croydon College (1.3 miles south-west of Addiscombe) take heavy use from students and staff alike. At a hotel such as Croydon Park Hotel, 1.2 miles to the south-west of Addiscombe, the quieter weeks are the time to reseal bathrooms. Office washrooms on sites such as Chaffinch Business Park, 1.3 miles to the north-east of Addiscombe, are in use all working day, so resealing is phased to keep some open.
Addiscombe is about 2 miles north-east of Croydon, in Greater London. We send applicators to Addiscombe for washrooms and wet areas, handled exactly as we handle every other area. 764 places across Greater London fall within our area, including Addiscombe. London is covered too, around 8 miles from Addiscombe.
If you need washroom sealing in CR0, SE25 and CR9, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Grant Road, Capri Road and Coe Avenue, and sites on any of them can send details for a fixed quote. With the A232 nearby, Addiscombe is easy to get to with materials and equipment. Just outside Addiscombe, we also work in Shirley Oaks (1 mile east), Ashburton (1 mile north), Woodside (1 mile north), Shirley (1 mile east) and Monks Orchard (1 mile east). Bigger towns within reach include London (8 miles north), City of Westminster (10 miles north), Marylebone (10 miles north), Kensington (10 miles north-west), St Pancras (10 miles north) and Shoreditch (10 miles north).

Surface by surface
Changing rooms and gyms
Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we will plan around them.
Kitchens and tea points
Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.
Your questions answered
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Can work in a care setting near Addiscombe go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you work in hospitals, clinics and care homes?
We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Aftercare for building managers
A few simple habits keep the new joints working:
- Respect the cure time before reopening each room
- Add sealant joints to planned maintenance checks
- Clear standing water from shower floors where possible
- Tell us about infection-control or permit rules before we quote
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job with more phasing to plan.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes between a morning and a week or so, set by the number of rooms and the phasing you need, and our waste is bagged and taken away as we go. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. 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.
- A phasing plan keeps part of the building’s facilities in use at all times.
- The failed silicone is stripped and every face scraped clean of residue.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Rooms reopen after the product’s cure time, and we move to the next.
Getting the site ready
- Point out parking and an unloading spot
- Warn occupants and staff about the work

Why deal with it now?
A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. Getting scaffold, permits or access booked in Addiscombe takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- A room that stays damp because ventilation isn’t working
- Leaks through tanking or membranes below the finishes
- Leaking pipes, traps, wastes or cisterns, which need a plumber
