Why act early in Sunninghill
When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Washroom sealing in Sunninghill, done properly
You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. Most enquiries involve stained or open joints at kitchen sinks and worktops and users noticing mouldy joints, across showers, trays and wet room floors, accessible toilets and changing rooms and kitchens and tea points. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sunninghill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around places like Sunninghill, hospitality kitchens and toilets see heavy use in busy spells. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.
Our workmanship is guaranteed for 12 months, in Sunninghill as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Sunninghill
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
A quote for washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Asbestos survey details if the building is older
- Where the site is, with the postcode
- The type of building and who uses it
- Access details, including height
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. For a site in Sunninghill, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Joints are cleaned, degreased and dried before sealing.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Rooms reopen after the product’s cure time, and we move to the next.
Before we start on site
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Move anything stored against the joints

General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Sunninghill: questions and answers
Is hospital work, at somewhere like Heatherwood Hospital, something you do?
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.
Does a hotel in Sunninghill need to shut while its sealant is renewed?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How do we ask for a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Wet areas in Sunninghill’s workplaces
The 2 miles around Sunninghill include two care or nursing homes. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Each room is kept out of use only as long as the sealant needs. A number of hotels sit less than 2 miles from Sunninghill. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice.
For a hall at a building such as Church of St Michael and All Angels, resealing the kitchen and toilets can be fitted between bookings. Office washrooms on sites such as Ascot Business Park (to the west of Sunninghill) are in use all working day, so resealing is phased to keep some open. En suites at hotels like Highclere Hotel, less than half a mile to the east of Sunninghill, are cleaned daily, which wears silicone over time.

What the job involves on each surface
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.
Changing rooms and gyms
Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.
