About our washroom sealing in Cookley Green
Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels so they get particular attention. Site teams most often ask us about complaints from staff, guests or users about tired washrooms and panel joints letting water behind, on IPS panels and cubicles, showers, trays and wet room floors and accessible toilets and changing rooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Cookley Green is the same: the right product in a properly prepared joint.
Halls and community buildings near places like Cookley Green 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.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Cookley Green are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- We agree which rooms close and when, so users always have somewhere to go.
- 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.
- You get a reopening time for every room, with signage left up until then.
Preparing the site
- Let building users know which areas are affected
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Vanity carcasses that have swollen
- Water escaping beneath the floor rather than through a joint
If in doubt, call 01277 525 020 or email us and we’ll say what we think before you book.

Different surfaces, different methods
Urinals and WC pans
Pan and urinal joints face constant cleaning and splashing. Stained or split joints here trap smells and look unhygienic.
Changing rooms and gyms
Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.
Looking after the joints
A few simple habits keep the new joints working:
- Keep a record of which washrooms need attention
- Make sure washroom ventilation is running
- Report split joints at trays and basins early
- Respect the cure time before reopening each room
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.

Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.

Signs you need washroom sealing in Cookley Green
A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old so it peels away quickly.
What tends to prompt an enquiry:
- Stained sealant around pans and urinals
- Washrooms that look worn because of the sealant
- Open joints along basins and vanity units
- Sealant stained black around basins and showers
For an occupier at a site such as Watlington Industrial Estate, which lies north of Cookley Green, the canteen and welfare facilities need cleanable joints as much as any office.
