How we handle expansion joint sealing in Windmill Hill
Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. We work on precast concrete panel joints, cladding panel joints and podiums and floor movement joints, and the usual reasons a site gets in touch are hardened, cracked sealant on exposed facades and sealant peeling off one face of the joint.

Around smaller places such as Windmill Hill, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement flagging broken arrises before sealing.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

Leave it or put it right?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We’ll flag where edges need repair before sealing. Converted and older buildings near places like Windmill Hill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why us?
- 12-month guarantee on workmanship
- Colours chosen to suit frames, cladding or finishes where possible

Where floor joints take the most wear near Windmill Hill
Windmill Hill is about 46 miles from central London. The roads out of London are lined with trade parks and distribution sheds. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.
Hospitals like Amberstone Hospital (2.8 miles west of Windmill Hill) have multi-storey or surface car parks whose joints carry vehicles round the clock.
Windmill Hill is about 4 miles north-east of Hailsham, in East Sussex. Anywhere in BN27, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our East Sussex coverage takes in 308 places. Sites around Brighton have their own page, about 21 miles away.

Your questions answered
Is a smaller place like Windmill Hill outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Does a site in Windmill Hill have to shut while its joints are sealed?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can staff carry on working while you’re here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What sealant do you use in movement joints?
The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane unless the specification names something else.
When to bring in 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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
When to call us in Windmill Hill
Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it.
Typical triggers for a call:
- Weathered movement joint sealant that no longer flexes
- Water getting into the wall through a failed joint
- Previous reseals laid over old sealant
- Movement joints with split or torn sealant
For a school such as Herstmonceux Church of England Primary School, playground and building joints can be done in the holidays.
