Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Washroom sealing in Chilworth, done properly
In a commercial washroom, sealant is usually the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. The enquiries we see most involve gaps where vanity tops meet the wall and urinal joints that look unhygienic, on showers, trays and wet room floors, accessible toilets and changing rooms and IPS panels and cubicles. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Chilworth, that means joint design, primers and backing rod as standard.
Farm shops, cafés and venues in converted rural buildings around places like Chilworth have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or use the quote form and we’ll come back to it.

What the job involves on each surface
Kitchens and tea points
Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sound joints keep those surfaces easy to clean.
Urinals and WC pans
The joint between a pan and the floor is easy to overlook. They are checked with everything else.

When to call us in Chilworth
A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.
Look out for the following:
- Failed joints along IPS and cubicle panels
- Stained or open joints at kitchen sinks and worktops
- Mould spotting along silicone joints
- Sealant laid over old silicone and now peeling
Student showers at universities like University of Surrey - Stag Hill Campus (3.1 miles north-west of Chilworth) see more use than most, and their silicone shows it.

Questions we’re asked in Chilworth
Is a hospital such as Mount Alvernia Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Chilworth too far out for you?
Not at all. Chilworth is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you phase washroom resealing?
The work is phased so there are always facilities open. We work through the building a room or section at a time around your site hours and access windows.
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
What sealant do you use in washrooms?
Sanitary silicone with anti-mould additives in most cases. We use neutral-cure versions on stone, some metals and near mirrors.
What happens if it’s left?
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 Chilworth, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
