Washroom sealing in Shirley
In a busy washroom, the sealant normally gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. We work on urinals and WCs, IPS panels and cubicles and kitchens and tea points, and what we’re called in for most is stained or open joints at kitchen sinks and worktops and panel joints letting water behind. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Shirley, preparation and product choice get the time they need.
Building managers in Shirley typically need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What else we do in Shirley
Why it’s worth doing now in Shirley
Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Failed sealant in a building in Shirley can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Surface by surface
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
Changing rooms and gyms
Shower areas, wet floor edges and vanity areas all have sealant joints, and we survey them together.
Your questions answered
Can you work around term dates at a campus such as Croydon College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is hospital work, at somewhere like Shirley Oaks Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes half a day to a day per washroom, depending on the number of fittings. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. In Shirley, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Preparing the site
- Agree which areas must stay open
- Share your working hours and any access restrictions
- Flag any permit to work we will need

Keeping Shirley washrooms open while we work
The area within 2 miles of Shirley holds a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest. Busy London buildings need some toilets open at all times, so we phase the work core by core or floor by floor with the building manager.
For buildings on a site such as Chaffinch Business Park, which lies north of Shirley, washrooms and tea points can be resealed in phases through the working week. Clinical washrooms at sites like Shirley Oaks Hospital (less than half a mile north-west of Shirley) are scheduled with the ward so the room is out of use for as little time as possible.
Shirley is about 2 miles north-east of Croydon, in Greater London. Our applicators travel to Shirley for work on washrooms and wet areas, handled exactly as we handle every other area. We work across 764 places in Greater London, large and small. For work in that direction, see our London page.
Work on washrooms and wet areas is covered throughout CR0, SE25 and CR9. We cover commercial and managed buildings on Poppy Lane, Homer Road and Craven Road and the roads nearby. Shirley sits on or close to the A232. We also cover Monks Orchard (1 mile north), Shirley Oaks (1 mile west), Addiscombe (1 mile west), Ashburton (1 mile north-west) and Woodside (1 mile north-west) for washrooms and wet areas. A short drive away, we cover London (8 miles north), City of Westminster (10 miles north-west), Marylebone (10 miles north-west), Kensington (10 miles north-west), St Pancras (10 miles north) and Shoreditch (10 miles north).

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- A dripping waste or valve behind a panel
- Vanity carcasses that have swollen
- Failed tanking beneath a wet-room floor or behind tiles
If in doubt, call 01277 525 020 or email us and we’ll say what we think before you book.
Surfaces we seal
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Urinals and WCs
- Kitchens and tea points
- Showers, trays and wet room floors
- Vanity units and basins
Signs you need washroom sealing in Shirley
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water and they discolour and fail early.
Look out for the following:
- Stained sealant around pans and urinals
- Users noticing mouldy joints
- Sealant laid over old silicone and now peeling
- Black mould inside silicone joints that cleaning can’t shift
Where you are responsible for a hall attached to a building such as St George The Martyr Church, its kitchen and toilets need sealant that stays cleanable.
