Washroom sealing for commercial buildings in Highbury
From one staff toilet in Highbury to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. If you’re dealing with complaints from staff, guests or users about tired washrooms and failed joints along IPS and cubicle panels, we can put it right, whatever the surface. Whoever orders the work in Highbury, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
In a London area such as Highbury, commercial washrooms in offices, hotels and leisure buildings see constant use. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Why it’s worth doing now in Highbury
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. In Highbury, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What sets the cost
The price varies from site to site. Expect it to depend on:
- The size and state of each joint
- Distance, for remote addresses
- Working within restricted access windows
- The product specified
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Specification clauses that apply
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- The type of building and who uses it
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or ring 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- 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.
- Rooms reopen after the product’s cure time, and we move to the next.
Preparing the site
- Have the specification and drawings to hand
- Make sure the joints can be reached
- Point out parking and an unloading spot

How the job changes by surface
Healthcare and care settings
Accessible and assisted washrooms are used and cleaned intensively so their sealant tends to fail sooner.
Kitchens and tea points
In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Food-safe sealants are used where food may touch the joint.
Commercial clients in Highbury
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Questions about Highbury
Can you take on a job at a hospital such as Moorfields Eye Hospital (City Road campus)?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do hotels near Highbury have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Will all the toilets be closed at once?
The work is phased so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we’ll plan around them.
Can you reseal washrooms in healthcare buildings?
Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.
Do you need to remove the old sealant?
We strip every bit of the failed bead and wipe away the residue before resealing. That’s what makes the new joint last.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Leaks through tanking or membranes below the finishes
- Loose panels, vanity units or tiles, which need fixing first
- A room that stays damp because ventilation isn’t working
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.

Busy facilities in and around Highbury
A London building with hundreds of occupants can’t lose every washroom for a day, so we phase the work core by core or floor by floor with the building manager. There are six care or nursing homes within about 2 miles of Highbury. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home.
Toilets at places like Arena Shopping Park, 1.7 miles north of Highbury, are cleaned constantly, so silicone needs to be sound and smooth. Welfare facilities in units on estates such as Frogmore Industrial Estate (to the north of Highbury) have showers, toilets and kitchens with sealant that works hard. Colleges such as City & Islington College (to the north of Highbury) have toilets, changing rooms and catering kitchens that can be resealed around term dates.
