How we handle expansion joint sealing in Westcott
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Westcott. If you’re dealing with torn sealant in brick or block movement joints and sealant pulling off the joint face, we can help, on car park decks and ramps, blockwork control joints and precast concrete panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Westcott, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Westcott have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Slabs, ramps and loading bays in Westcott
Westcott is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. Westcott lies roughly 44 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day.
For an estate such as St John's Hospital, 4.6 miles south-east of Westcott, the joints in ramps, decks and long building elevations all need attention over time. On a site such as Lawn Farm Business Centre (2.3 miles north-west of Westcott), the movement joints are in car park slabs, paving and building elevations.
Westcott is about 6 miles west of Aylesbury, in Buckinghamshire. Across the HP18 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. For a building around Westcott, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Share your working hours and any access restrictions
- Have the specification and drawings to hand
- Arrange parking or a loading space

Why deal with it now?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Halls, stores and units around places like Westcott may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
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.

Looking after the joints
To get the most from the new sealant:
- Raise snow-clearing blades over deck joints where possible
- Plan racking layouts so feet don’t land on a joint
- Act on the first tear or lifting edge rather than waiting
- Leave barriers in place until fresh joint sealant has cured
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.
Common problems we fix in Westcott
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.
It’s worth sending us details if you spot any of the following:
- Sealant pulling off the joint face
- Movement joints with split or torn sealant
- Layers of sealant in a movement joint
- Rain penetration at brick or block movement joints
Schools such as Westcott Church of England School have movement joints in their walls and floors that are easy to overlook.
What to look for in a quote

- Their plan for phasing and protecting the area
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Concrete or masonry repairs along the arrises
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

FAQs: Westcott
Can you take on a job at a hospital such as St John's Hospital?
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.
Is Westcott too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
What exactly is a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably.
Do you use silicone or polyurethane in movement joints?
We choose a sealant with a movement capability that suits the joint as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
Can you work on car park ramps and decks?
Yes. Tell us how the car park is used and which areas must stay open, and we’ll plan the phasing around it.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
