Washroom sealing for commercial buildings in Upper Holloway
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. Most enquiries involve users noticing mouldy joints and kitchen worktop joints that can’t be kept clean, on accessible toilets and changing rooms, vanity units and basins and urinals and WCs. A single leaking joint is often how a building in Upper Holloway first comes to us: we look at the rest while we are there and tell you what we find.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Common questions from Upper Holloway clients
Could you schedule work at a campus like American University in London for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you work on a hospital site such as The Whittington Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you reseal washrooms in healthcare buildings?
We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote before we start.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. In Upper Holloway, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Each area is handed back when ready.
Getting the site ready
- Have the specification and drawings to hand
- Tell us what induction or permit system the site runs
- Agree which areas must stay open

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Water escaping beneath the floor rather than through a joint
- A dripping waste or valve behind a panel
- Loose panels, vanity units or tiles, which need fixing first
If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think before you book.
Where we work in Upper Holloway
- Vanity units and basins
- Accessible toilets and changing rooms
- Urinals and WCs
- Kitchens and tea points
- Showers, trays and wet room floors
- IPS panels and cubicles
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What the job involves on each surface
Basins and vanity tops
Vanity tops and basins are splashed all day, 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.
Healthcare and care settings
Clinics, hospitals and care homes need joints that can be kept clean. We work to your estates and infection-control requirements as well as site permits.
Wet areas in Upper Holloway’s workplaces
The 2 miles around Upper Holloway include five 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. Plenty of hotels sit less than 2 miles from Upper Holloway. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.
At a hospital like The Whittington Hospital, under half a mile north-west of Upper Holloway, patient and staff washrooms are best done in short phases agreed with the ward. Units at estates like Bush Industrial Estate (to the south of Upper Holloway) have welfare blocks whose showers and toilets see shift after shift.
