How the job changes by surface
Changing rooms and gyms
Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.
Kitchens and tea points
In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Food-safe sealants are used where food may touch the joint.
About our washroom sealing in Startop's End
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on urinals and WCs, showers, trays and wet room floors and kitchens and tea points, and the failures we are asked to look at most are gaps where vanity tops meet the wall and stained or open joints at kitchen sinks and worktops. Most enquiries from Startop's End 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.
Community buildings around smaller places like Startop's End have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What else we do in Startop's End
Questions we are asked in Startop's End
Is hospital work, at somewhere like Tindal Centre, something you do?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will the toilets in our Startop's End building be out of use?
Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Is it OK to put new silicone on top of the old?
The whole of the old bead is removed and the surfaces cleaned before resealing. It’s the difference between a joint that lasts and one that peels.
Can you clean the mould off instead of resealing?
Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking half a day to a day per washroom, depending on the number of fittings. If others near Startop's End need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Failed tanking beneath a wet-room floor or behind tiles
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.
Joints and surfaces we work on
- Vanity units and basins
- Urinals and WCs

Why it’s worth doing now in Startop's End
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. Older rural buildings around Startop's End move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
