Washroom sealing in Friern Barnet
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. If you are dealing with urinal joints that look unhygienic and complaints from staff, guests or users about tired washrooms, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Friern Barnet tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
After the work
For the best life from the joints:
- Add sealant joints to planned maintenance checks
- Avoid scourers and harsh descalers on silicone
- Act on the first split you see at a shower tray
- Keep extract fans working and vents clear
Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.
Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.
What the job involves on each 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.
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.
Questions about Friern Barnet
Does a hotel in Friern Barnet need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.
Will you work in a care home in Friern Barnet without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you need to remove the old sealant?
The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.
Is it possible to just clean mouldy silicone?
Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Friern Barnet can sit alongside others in a wider programme.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For a job in Friern Barnet, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- 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.
- We strip out the old bead and clean off the residue left behind.
- Joints are cleaned, degreased and dried before sealing.
- 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.
What we need from you
- Have the specification and drawings to hand
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs

- Vanity carcasses that have swollen
- Leaking pipes, traps, wastes or cisterns, which need a plumber
