Joints that move: notes for Dukes Green
The sea is no more than about 3 miles from Dukes Green. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Dukes Green is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
Schools such as Alfriston School have movement joints in their walls and floors that are easy to overlook. Sites like Chailey Heritage Marine Hospital (3.8 miles west of Dukes Green) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Why it’s worth doing now in Dukes Green
A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall. Acting at the first split keeps the cost down. Older rural buildings around Dukes Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Do you need expansion joint sealing in Dukes Green?
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Clients usually get in touch after noticing something like this:
- New sealant over old, now failing
- Weathered movement joint sealant that no longer flexes
- Water getting into the wall through a failed joint
- Movement joints with split or torn sealant
Phasing is what makes joint work possible on busy sites such as Cradle Hill Industrial Estate (1.8 miles south-west of Dukes Green): one bay, aisle or car park row at a time.
Before you book anyone
- Can the work be phased to keep areas open?
- How they handle RAMS and site documents
- Are they CHAS accredited or on Constructionline?
- Proof of insurance
What sets the cost
To price the job, we consider:
- Location, for remote and island sites
- The size and state of each joint
- How much there is to seal
- How accessible the joints are
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Any specification or named product
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- Whether an asbestos survey exists
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email us.
Our process
On arrival, 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 anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. If others near Dukes Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand

Dukes Green: questions and answers
Is a hospital such as Chailey Heritage Marine Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Can being near the sea in Dukes Green affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Can staff carry on working while you are here?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
What will the job 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 and we’ll price it properly.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Crumbling edges that would give a new bead nothing sound to grip
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
