Washroom sealing for commercial buildings in Finchley
Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. If you have open joints at the base of cubicle panels and open joints along basins and vanity units, we can help, whatever the surface. Most enquiries from Finchley start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In Finchley, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Do you need washroom sealing in Finchley?
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.
These are often picked up first by site or facilities staff:
- Users noticing mouldy joints
- Sealant laid over old silicone and now peeling
- Open joints at the base of cubicle panels
- Black mould inside silicone joints that cleaning can’t shift
Halls of residence and teaching buildings at universities such as Middlesex University (2.6 miles west of Finchley) are easiest to reseal during vacations.

What else we do in Finchley
Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Share your site rules when you send details
- Don’t leave an open joint at a basin or tray
- Note failing joints building by building
- Keep extract fans working and vents clear
Ventilation is half the battle. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.
Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.
Busy facilities in and around Finchley
The 2 miles around Finchley include nine care or nursing homes. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Rooms are done a few at a time at times agreed with the home. In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team.
Staff changing rooms and patient toilets at places like Finchley Memorial Hospital (to the north-east of Finchley) need cleanable, sound silicone. Toilets at colleges like St. Giles College (2.4 miles south-east of Finchley) take heavy use from students and staff alike.

Why act early in Finchley
A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Resealing is a modest task with a very visible payoff. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Your questions answered
Can you work in a care home near Finchley with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Is hospital work, at somewhere like Finchley Memorial Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
What guarantee comes with washroom resealing?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you need to remove the old sealant?
We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Finchley, 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 inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.
- Joints are degreased and dried.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Rooms reopen after the cure time.
Before we start on site
- Explain the parking and delivery arrangements
- Send your site hours and access windows
- Warn occupants and staff about the work

How the job changes by surface
Showers and trays
A tray that rocks or has cracked won’t be fixed by sealant, and we’ll say so before resealing.
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.
Cost factors for washrooms and wet areas
Quotes vary with the job. It mainly depends on:
- The size and state of each joint
- Site requirements such as inductions and permits
- Travel to remote or island sites
- Whether old sealant has to be cut out first
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
However big the job, these details speed things up:
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- Specification clauses that apply
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email a schedule or drawings.
