Washroom sealing for Brook sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How the job changes by surface
Wet-room floors and floor-to-wall joints
Floor edges in wet areas are where water most often escapes. We reseal the floor-to-wall junctions and around drains where sealant is used.
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.
How we handle washroom sealing in Brook

There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. Site teams most often ask us about split or peeling sealant at shower trays and mould spotting along silicone joints, across kitchens and tea points, showers, trays and wet room floors and accessible toilets and changing rooms.

What else we do in Brook
Owners, agents and contractors
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Why act early in Brook
When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Converted and older buildings near places like Brook tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Brook: questions and answers
Is hospital work, at somewhere like Milford Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Brook outside your area?
No. Places such as Brook are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What guarantee comes with washroom resealing?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
Can you clean the mould off instead of resealing?
Typically not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.
Can washrooms stay open while you work?
Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.
Do you use special sealant for toilets and showers?
It depends on the joint. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- A dripping waste or valve behind a panel
- Fittings that move too much to hold a bead
- Failed tanking beneath a wet-room floor or behind tiles
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.
Surfaces we seal
- Vanity units and basins
- Showers, trays and wet room floors
- Kitchens and tea points
- Urinals and WCs
- Accessible toilets and changing rooms
- IPS panels and cubicles

Signs you need washroom sealing in Brook
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.
Common reasons buildings call us in:
- Panel joints letting water behind
- Washrooms that look worn because of the sealant
- Urinal joints that look unhygienic
- Resealing that didn’t last because the old bead stayed
Hotels such as The White Hart Hotel (1.5 miles north-east of Brook) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.
