Questions we’re asked in Kingston
Do you take on work at healthcare sites like St James Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will our hotel in Kingston need to close for the work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
Can the sealant be colour-matched?
It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Can washrooms stay open while you work?
Just the room being resealed is out of use. Each room reopens after the sealant’s cure time and we start the next.
Is there a guarantee on the work?
Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
How long before the toilets can reopen?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.
What do you charge?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email a schedule or drawings.
Washroom sealing for commercial buildings in Kingston
Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. If you’re dealing with failed sealant behind washroom basins and open joints at the base of cubicle panels, we can put it right, on IPS panels and cubicles, urinals and WCs and showers, trays and wet room floors alike. Facilities teams, main contractors and managing agents in Kingston tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In a smaller place such as Kingston, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What happens if it’s left?
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 smaller place such as Kingston, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Building owners, agents and FMs in Kingston
Building owners and managing agents use us on everything from one building to a spread of sites around Kingston. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Looking after the joints
To get the most from the new sealant:
- Clean sealant with gentle products and a soft cloth
- Leave signs up until the cure time is over
- Don’t leave an open joint at a basin or tray
- Squeegee showers and trays after busy periods
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Several jobs near Kingston can be grouped on one trip. Mention the building’s opening times and we will work within them.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Rooms reopen after the cure time.
Getting the site ready
- For older buildings, check the asbestos register before work
- Send your site hours and access windows
- Have the specification and drawings to hand
Quotes
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Typical triggers for a call:
- Sealant laid over old silicone and now peeling
- Complaints from staff, guests or users about tired washrooms
- Panel joints letting water behind
- Sealant stained black around basins and showers
