About our washroom sealing in Swiss Cottage
In a commercial washroom, sealant is usually the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have sealant stained black around basins and showers and sealant lifting along a tray edge, we can help, whatever the surface. Looking for mastic applicators who cover Swiss Cottage? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In a London area such as Swiss Cottage, 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.
A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or use the quote form and we will arrange a return visit.

Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Include joints in routine washroom inspections
- Make sure washroom ventilation is running
- Keep a record of which washrooms need attention
- Don’t leave an open joint at a basin or tray
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.
Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

What happens if it’s left?
A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
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 easy to get wrong without experience.
Wet areas in Swiss Cottage’s workplaces
A good number of hotels sit less than 2 miles from Swiss Cottage. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping. Swiss Cottage has three care or nursing homes no more than 2 miles away. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. We plan the work with the manager so residents are disturbed as little as possible.
At a university such as Regent's University London, which lies south-east of Swiss Cottage, summer is the usual window for resealing residence bathrooms. Customer toilets in retail centres such as O2 Centre, 0.5 miles north-west of Swiss Cottage, rarely close, so resealing is phased.

FAQs: Swiss Cottage
Do you work in occupied care homes around Swiss Cottage?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Can you work on a hospital site such as Hospital of St John and St Elizabeth?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What do you charge?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
How do you deal with asbestos in old sealant?
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.
Do you do washroom sealing in healthcare settings?
We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote.
When to call us in Swiss Cottage
Daily commercial cleaning wears sealant faster than people expect. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.
Look out for the following:
- Urinal joints that look unhygienic
- Panel joints letting water behind
- Sealant lifting along a tray edge
- Complaints from staff, guests or users about tired washrooms
For buildings on a site such as Regis Road Business Park (1.4 miles north-east of Swiss Cottage), washrooms and tea points can be resealed in phases through the working week.
Before you book anyone
- Who will actually carry out the work
- Are they CHAS accredited or on Constructionline?
- Proof of insurance
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go. In Swiss Cottage, 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.
- We agree which washrooms close and when.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
What we need from you
- Send your site hours and access windows
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance
