Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. For a job in South Croydon, access comes first. Give us the hours we can be on site and we will schedule to suit.
- First, the phasing is agreed so facilities stay open.
- 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 confirm reopening times for each washroom.
Before we start on site
- Tell staff and tenants when we will be in
- Send your site hours and access windows
- Make sure the joints can be reached

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Advice
About our washroom sealing in South Croydon
Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels so they get particular attention. If you are dealing with mould spotting along silicone joints and complaints from staff, guests or users about tired washrooms, we can help. Most enquiries from South Croydon 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 South Croydon normally need some facilities open throughout. We work through washrooms floor by floor or core by core, at times agreed with you.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from South Croydon clients
Do you work in occupied care homes around South Croydon?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
Is a hospital such as Purley War Memorial Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Will cleaning remove black mould from sealant?
Usually not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.
How do you deal with asbestos in old sealant?
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.
Leave it or put it right?
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and your cleaning team stops chasing it. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What you get with us

Do you need washroom sealing in South Croydon?
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.
Things that normally lead to an enquiry:
- Users noticing mouldy joints
- Sealant laid over old silicone and now peeling
- Failed sealant in a tea point or staff kitchen
- Gaps where vanity tops meet the wall
If you manage an office at a site such as Capital Business Centre, less than half a mile to the east of South Croydon, the washrooms and tea points can be done a floor at a time.

What sets the cost
We price every job individually. The main factors are:
- Phasing around occupants
- Location, for remote and island sites
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- Any specification or named product
- What the building is and how it’s used
- The asbestos register, for older buildings
- Where the site is, with the postcode
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Keeping South Croydon washrooms open while we work
Busy London buildings need some toilets open at all times, so resealing goes floor by floor, agreed with the facilities team. A good number of hotels sit less than 2 miles from South Croydon. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice.
For centre management at a site such as Whitgift Centre, 1.6 miles north of South Croydon, washroom work is planned around footfall. Healthcare washrooms on sites such as Purley War Memorial Hospital, 1.2 miles to the south-west of South Croydon, are resealed area by area, under the site’s own infection-control rules.
South Croydon is about 1 mile south of Croydon, in Greater London. Any commercial site in South Croydon is covered, for single jobs and planned programmes alike. We work across 764 places in Greater London, large and small. We also cover London, some 10 miles away.

Keeping the joints sound
After handover, these steps help:
- Add sealant joints to planned maintenance checks
- Brief cleaning staff to treat joints gently
- Photograph and log failed joints across the estate
- Make sure washroom ventilation is running
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
Different surfaces, different methods
Basins and vanity tops
Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.
Wet-room floors and floor-to-wall joints
We seal the visible joints; we don’t install or repair waterproofing below and point it out if water appears to rise from below.
