Washroom sealing in Vale of Health
When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. The enquiries we see most involve panel joints letting water behind and sealant laid over old silicone and now peeling, across accessible toilets and changing rooms, showers, trays and wet room floors and IPS panels and cubicles. Most enquiries from Vale of Health start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.
Every job we finish is backed by a 12-month workmanship guarantee, in Vale of Health as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Vale of Health
Can you work on a hospital site such as Royal Free Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you take on jobs in Vale of Health where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Do you work in Vale of Health?
Yes. Vale of Health is in our area and the rest of Greater London. For a quote, call 01277 525 020 or send photos by email.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Do you phase washroom resealing?
We phase it so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.
Is it OK to put new silicone on top of the old?
We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Swollen or delaminated boards behind panels or vanity tops
- Leaks through tanking or membranes below the finishes
- Leaking pipes, traps, wastes or cisterns, which need a plumber
If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer.
Where we work in Vale of Health
- Accessible toilets and changing rooms
- Kitchens and tea points
- Showers, trays and wet room floors
- IPS panels and cubicles
- Vanity units and basins
- Urinals and WCs
Leave it or put it right?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. 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 Vale of Health can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

From enquiry to sign-off
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We agree which washrooms close and when.
- 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 confirm reopening times for each washroom.
Getting the site ready

Site staff or a sealant specialist?
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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Rooms are done a few at a time at times agreed with the home. Busy London buildings need some toilets open at all times, so we take one block of facilities out of use at a time.
