Washroom sealing for Holwellbury sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Your questions answered
Can work at a site such as University of Bedfordshire fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on work at healthcare sites like Fairfield Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Is it OK to put new silicone on top of the old?
We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.
How much does the work cost?
We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.
Which silicone is right for commercial washrooms?
Sanitary silicone with anti-mould additives in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
About our washroom sealing in Holwellbury
Not every silicone belongs in a washroom. 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. Most enquiries involve a new bead over an old one coming away and open joints along basins and vanity units, across accessible toilets and changing rooms, kitchens and tea points and showers, trays and wet room floors. A specialist sealant contractor works differently from a general builder: on jobs in Holwellbury, preparation and product choice get the time they need.
Halls and community buildings near places like Holwellbury are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Water escaping beneath the floor rather than through a joint
- Fittings that move too much to hold a bead
- Leaking pipes, traps, wastes or cisterns, which need a plumber
If you’re not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Joints and surfaces we work on
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Showers, trays and wet room floors
- Vanity units and basins
- Kitchens and tea points
- Urinals and WCs
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Brief cleaning staff to treat joints gently
- Act on the first split you see at a shower tray
- Squeegee showers and trays after busy periods
- Inspect washroom sealant regularly
Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.
Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Surface by surface
IPS and cubicle panels
IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.
Urinals and WC pans
Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. If others near Holwellbury need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Rooms reopen after the product’s cure time, and we move to the next.
Getting the site ready
- Let building users know which areas are affected
- Move anything stored against the joints
- Have the specification and drawings to hand

When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Certain joints really need a specialist: 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.
