Questions about Belvedere
Is hospital work, at somewhere like Erith and District Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Could you schedule work at a campus like University of East London for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you guarantee washroom sealing?
Our workmanship has a 12-month guarantee backed by public liability insurance.
Do you work in Belvedere?
Yes. We cover Belvedere, and the simplest way to start is to give us a call on 01277 525 020 or send details through our quote form.
Do you need to remove the old sealant?
The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Washroom sealing for commercial buildings in Belvedere
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. We work on vanity units and basins, kitchens and tea points and accessible toilets and changing rooms, and what we’re called in for most is open joints at the base of cubicle panels and sealant lifting along a tray edge. Looking for mastic applicators who cover Belvedere? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. 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 sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Surface by surface
Showers and trays
Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.
Urinals and WC pans
We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What affects the price in Belvedere
Before we quote, we look at:
- The size and state of each joint
- How much there is to seal
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Sending details for a quote
We can often quote from photographs and a few details. It helps to include:
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
- Your programme or deadline
- How the joints are reached, and at what height
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, call 01277 525 020 or email the details over.

After the work
For the best life from the joints:
- Add sealant joints to planned maintenance checks
- Keep washrooms out of use until we say the sealant has cured
- Squeegee showers and trays after busy periods
- Report faulty extraction promptly
We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used and signage stays in place until that time.
Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Failed tanking beneath a wet-room floor or behind tiles
- Swollen or delaminated boards behind panels or vanity tops
- A room that stays damp because ventilation isn’t working
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a job in Belvedere, access comes first. Send the building rules and access times with your enquiry.
- 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.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Preparing the site
- Confirm the product named in the specification
- Point out any areas we must not close
- Clear stock, furniture or equipment away from the joints

Two care or nursing homes sit less than 2 miles from Belvedere. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs. In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team.

Units at estates like Atlas Trade Park (to the south-east of Belvedere) have welfare blocks whose showers and toilets see shift after shift.
