Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Wet areas in Coulsdon’s workplaces
The 2 miles around Coulsdon include nine care or nursing homes. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Rooms are done a few at a time at times agreed with the home. In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team.
At a school such as Smitham Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. Units at estates like Ullswater Industrial Estate (to the north-east of Coulsdon) have welfare blocks whose showers and toilets see shift after shift.

About our washroom sealing in Coulsdon
From one staff toilet in Coulsdon to washrooms across a whole estate, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. Most enquiries involve failed joints along IPS and cubicle panels and a new bead over an old one coming away, across urinals and WCs, vanity units and basins and showers, trays and wet room floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Coulsdon it comes down to the same thing: the right product in a properly prepared joint.
In Coulsdon, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why deal with it now?
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and we clear our waste as we work. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Each joint is cleaned and left dry.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Getting the site ready
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints

What else we do in Coulsdon
Different surfaces, different methods
Changing rooms and gyms
Gym and leisure changing rooms see showers running most of the day, so mould is a constant battle. We use anti-mould sanitary silicone throughout.
IPS and cubicle panels
Panel systems meet walls, floors and vanity tops at sealed joints. Those joints protect the boards behind from water.
Commercial clients in Coulsdon
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Coulsdon can sit alongside others in a wider programme across Greater London.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Do you need washroom sealing in Coulsdon?
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
Things that normally lead to an enquiry:
- Sealant laid over old silicone and now peeling
- Stained or open joints at kitchen sinks and worktops
- Discoloured joints around urinals and WC pans
- Sealant stained black around basins and showers
On a healthcare site such as Purley War Memorial Hospital, which lies north-east of Coulsdon, washroom work starts with the infection-control team’s sign-off.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- The named product and why it was chosen
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
When to bring in a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
FAQs: Coulsdon
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.
Do you take on work at healthcare sites like Purley War Memorial 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.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
How soon can a washroom be used after resealing?
Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.
Do you phase washroom resealing?
Only the area we are working in is closed. Rooms go back into use once the sealant has cured, then we move on.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Is it possible to just clean mouldy silicone?
Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.
