Facade sealing in Castle Town
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. We work on shopfront frames, window and door perimeters and perimeter joints where frames meet the structure, and what we are called in for most is new sealant peeling off old mastic and water coming in around window frames. Searching for sealant specialists in Castle Town? We’ve been sealing commercial buildings since 2005.
Conversions of older rural buildings near smaller places such as Castle Town bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Mastic packages on Castle Town sites
Castle Town is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Castle Town has a number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
With historic properties like Portslade Manor, 4.2 miles to the south-east of Castle Town, in the area, refurbishment work often meets old masonry that needs compatible sealants. Recladding or extending a unit at a site like Mackley Industrial Estate, 1.7 miles to the north-east of Castle Town, brings panel joints and frame perimeters into the programme.
Castle Town is about 3 miles north of Shoreham-by-Sea, in West Sussex. We send applicators to Castle Town for facade joints. Castle Town is one of 373 places in West Sussex on our list for facade joints. Brighton is covered too, around 8 miles from Castle Town.

How the quote is worked out
Each job is priced on its own details. The main factors are:
- Phasing around occupants
- Travel to remote or island sites
- Backing rod, priming and other preparation
- Any access equipment needed
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- Where the site is, with the postcode
- Any specification or named product
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email a schedule or drawings.

Common problems we fix in Castle Town
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.
It’s worth sending us details if you spot any of the following:
- Perimeter sealant that has split or peeled away
- Damp patches beside frames after rain
- Old perimeter mastic that has dried out
- Air leaks through failed facade joints
Extensions at sites like Southlands Hospital, 3.1 miles south-east of Castle Town, typically sit beside working departments, and the mastic follows strict access rules.

Castle Town: questions and answers
Can you work on a hospital site such as Southlands Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Mackley Industrial Estate, near Castle Town, within your area?
Yes. Our area takes in Castle Town and its surroundings, with estates and business parks such as Mackley Industrial Estate included. Photos and a short description are enough for a first look.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Do you work in Castle Town?
Yes. We cover Castle Town, and you can call the office on 01277 525 020 or email a schedule or drawings to get started.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What happens if it’s left?
Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. One visit to deal with every failing joint makes more sense than several trips to a place like Castle Town, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. 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 look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Preparing the site
- Warn occupants and staff about the work
- Point out parking and an unloading spot
- Confirm the product named in the specification
