Your questions answered
Does a hotel in Osidge need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.
Will you plan work around the academic year at somewhere like Oak Hill College?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
Do you do washroom sealing in healthcare settings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.
How do I request a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.
Will all the toilets be closed at once?
Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.
Washroom sealing for commercial buildings in Osidge
You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. If you have open joints at the base of cubicle panels and failed sealant in a tea point or staff kitchen, we can help, on vanity units and basins, showers, trays and wet room floors and kitchens and tea points alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Osidge it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as Osidge, commercial washrooms in offices, hotels and leisure buildings see constant use. 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.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Work is agreed with the manager, around residents’ routines. There are a number of hotels within about 2 miles of Osidge. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.
At a hospital like Priory Hospital (1 mile east of Osidge), patient and staff washrooms are best done in short phases agreed with the ward. For a hotel such as Southgate Hotel London, 0.6 miles to the east of Osidge, resealing en suites a few rooms at a time keeps the rest available. Where you are responsible for a hall attached to a building such as St Andrew's Church, its kitchen and toilets need sealant that stays cleanable.

Why act early in Osidge
Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Avoid scourers and harsh descalers on silicone
- Report split joints at trays and basins early
- Leave signs up until the cure time is over
- Make sure washroom ventilation is running
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.
Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.

When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
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. Getting these wrong typically costs more in the end than doing them right.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes half a day to a day per washroom, depending on the number of fittings, and our waste is bagged and taken away as we go. For a job in Osidge, access comes first. Give us the hours we can be on site and we will schedule to suit.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
What we need from you
- Share the asbestos register for older buildings
- Confirm the product named in the specification
- Move anything stored against the joints

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Panel boards already damaged by water
- Failed tanking beneath a wet-room floor or behind tiles
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.
Surfaces we seal
- Kitchens and tea points
- IPS panels and cubicles
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- Vanity units and basins
- Urinals and WCs
