Washroom sealing in Dunsbury, done properly
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 once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have panel joints letting water behind and mould spotting along silicone joints, we can help, whatever the surface. Most enquiries from Dunsbury 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.
Farm shops, cafés and venues in converted rural buildings around places like Dunsbury have busy toilets and kitchens. We plan the work around bookings and opening times.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What we’re called out for in Dunsbury
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.
If one of these sounds familiar, it’s time for a closer look:
- A new bead over an old one coming away
- Sealant lifting along a tray edge
- Urinal joints that look unhygienic
- Sealant stained black around basins and showers
Halls linked to places like St. Mary's Church host groups all week, which is hard on kitchen and toilet sealant.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Their pre-qualification and accreditations
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
Busy facilities in and around Dunsbury
Dunsbury sits close to the coast, within about 1 mile, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, so resealing in the quieter months keeps rooms ready.
In any commercial washroom in or near Dunsbury, mouldy sealant is cut out rather than cleaned, and anti-mould sanitary silicone goes on clean, dry joints.

Common questions from Dunsbury clients
Do we have to close all our washrooms in Dunsbury for resealing?
Normally only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.
Is a smaller place like Dunsbury outside your area?
Not at all. Dunsbury is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you clean the mould off instead of resealing?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
When can showers be used after new sealant?
Cure times vary by product and temperature. Each room gets its own reopening time from us, and signs stay up until then.
What do you charge?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, 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 prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Leave it or put it right?
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. Replacement deals with the cause in the joint and your cleaning team stops chasing it. Around Dunsbury, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Advice
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Act on the first split you see at a shower tray
- Clear standing water from shower floors where possible
- Keep extract fans working and vents clear
- Respect the cure time before reopening each room
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.
In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.
