How we handle washroom sealing in Netley Marsh
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. If you have shower tray joints that have opened up and users noticing mouldy joints, we can put it right. Facilities teams, main contractors and managing agents in Netley Marsh tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Community buildings around smaller places like Netley Marsh have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What the job involves on each surface
IPS and cubicle panels
Panels flex slightly in use so the bead needs to cope with it. Loose panels are flagged before any sealant goes on.
Urinals and WC pans
The joint between a pan and the floor is easy to overlook. We include them in the survey.
When to call us in Netley Marsh
Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
Most enquiries start with one or more of the following:
- Discoloured joints around urinals and WC pans
- Resealing that didn’t last because the old bead stayed
- Failed joints along IPS and cubicle panels
- Split or peeling sealant at shower trays
On a healthcare site such as Tatchbury Mount Hospital (1.1 miles north of Netley Marsh), washroom work starts with the infection-control team’s sign-off.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- The terms of the workmanship guarantee
- Will RAMS and insurance details be available?
- Will CSCS-carded applicators be on site?
What happens if it’s left?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Older rural buildings around Netley Marsh move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

FAQs: Netley Marsh
Is Netley Marsh off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Would you work within a site like Tatchbury Mount Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do you work in hospitals, clinics and care homes?
Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote before we start.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Maintenance after handover
For the best life from the joints:
- Clear standing water from shower floors where possible
- Note failing joints building by building
- Don’t leave an open joint at a basin or tray
- Mention any site permits or estates rules at quote stage
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.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.
