Washroom sealing in High Barnet, done properly
In a commercial washroom, sealant is typically the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on vanity units and basins, kitchens and tea points and IPS panels and cubicles, and the usual reasons a site gets in touch are urinal joints that look unhygienic and panel joints letting water behind. Whether you call it commercial sealant work, mastic application or joint sealing, in High Barnet it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
Every job we finish is backed by a 12-month workmanship guarantee, in High Barnet as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints
To get the most from the new sealant:
- Keep washrooms out of use until we say the sealant has cured
- Add sealant joints to planned maintenance checks
- Share your site rules when you send details
- Photograph and log failed joints across the estate
Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again, and it helps if signs stay up until then.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Commercial washrooms in High Barnet
Busy London buildings need some toilets open at all times, so we take one block of facilities out of use at a time. The 2 miles around High Barnet include five care or nursing homes. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs.
Healthcare washrooms on sites such as Barnet Hospital, 0.5 miles south-west of High Barnet, are resealed area by area, under the site’s own infection-control rules.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a job in High Barnet, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- We survey each room, count the joints and note anything behind them that needs another trade.
- We agree which rooms close and when, so users always have somewhere to go.
- The failed silicone is stripped and every face scraped clean of residue.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
Before we start on site
- Send any specification or drawings in advance
- Send your site hours and access windows
- Tell us which areas need to stay in use

How the job changes by surface
Showers and trays
A tray flexes every time it’s used and is constantly wet. Tray perimeters are a frequent source of leaks.
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.
Leave it or put it right?
Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. Failed sealant in a building in High Barnet can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
