What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Removal of failed or old sealant
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The asbestos register, for older buildings
- Where the site is, with the postcode
- Any specification or named product
- The type of building and who uses it
For a fixed quote, phone 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Panel boards already damaged by water
- Hollow tiles or loose panels behind the joint
- A dripping waste or valve behind a panel
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think.
What we seal
- Kitchens and tea points
- IPS panels and cubicles

Questions about Castle Town
Do hotels near Castle Town have to close for sealant work?
In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
Can you take on a job at a hospital such as Southlands 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.
Do you work in hospitals, clinics and care homes?
We do. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Is Castle Town in your area?
Yes. Castle Town is in our area. For a quote, call 01277 525 020 or email us.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Aftercare for building managers
For the best life from the joints:
- Don’t leave trays and floors sitting wet
- Include joints in routine washroom inspections
- Avoid scourers and harsh descalers on silicone
- Note failing joints building by building
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.
Common problems we fix in Castle Town
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.
Common reasons buildings call us in:
- Failed sealant in a tea point or staff kitchen
- Open joints at the base of cubicle panels
- Sealant stained black around basins and showers
- Complaints from staff, guests or users about tired washrooms
For a hotel such as Old Tollgate Hotel & Restaurant (0.9 miles west of Castle Town), resealing en suites a few rooms at a time keeps the rest available.
Questions to ask before you book
- What site paperwork they can supply
- What level of public liability insurance do they hold?
- Is the sealant right for the movement and the substrate?
- How joint depth will be controlled
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Castle Town need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use
- Tell staff and tenants when we will be in

Washroom sealing around Castle Town: how the place shapes the job
Central London is about 44 miles from Castle Town. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available. There are several hotels within about 2 miles of Castle Town. 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.
Clinical washrooms at sites like Southlands Hospital (3.1 miles south-east of Castle Town) are scheduled with the ward so the room is out of use for as little time as possible. On an industrial estate such as Mackley Industrial Estate, 1.7 miles to the north-east of Castle Town, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Around Castle Town
Around Castle Town, our work takes us to commercial buildings near Steyning Grammar School and Hillside Park (parke sa Hiniusang Gingharian) and the streets around them. Castle Town’s nearest station is Shoreham-By-Sea station, about 3.2 miles south of the centre. Well-known places in the area include Southlands Hospital (3.1 miles south-east) and Steyning Museum (1.5 miles north-west). The countryside around Castle Town includes Mill Hill and Truleigh Hill.
What happens if it’s left?
Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Halls, stores and units around places like Castle Town may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
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.
