Expansion joint sealing in West Thorney, done properly
For movement joints in West Thorney, photos and approximate lengths are the best start. We’ll come and look where photos don’t show enough. You can also speak to us on 01277 525 020 or email us to talk the joints through. We work on car park decks and ramps, brickwork movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and chipped joint edges on forklift routes. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in West Thorney it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places such as West Thorney, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Joints that move: notes for West Thorney
West Thorney sits close to the coast, within about 1 mile. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. West Thorney is about 59 miles 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.
On industrial estates such as Finchwood Farm Industrial Estate (2.5 miles west of West Thorney), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Sites like Havant War Memorial Hospital (to the north-west of West Thorney) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
West Thorney is about 5 miles south-east of Havant, in West Sussex. Businesses, contractors and managing agents in West Thorney use us for work on movement joints. West Thorney is one of 373 places in West Sussex on our list. Our Portsmouth page has more on work in that area (7 miles or so).

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Smaller jobs around West Thorney can be grouped with others nearby. A fixed quote is given before anything starts.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- 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.

When to call us in West Thorney
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.
Look out for the following:
- Leaks through car park deck joints onto the level below
- Damp inside where a wall movement joint has failed
- Expansion joints filled with dirt and stones
- Sealant peeling off one face of the joint
Phasing is what makes joint work possible on busy sites such as Southfield Industrial Park. (2.9 miles north-east of West Thorney): one bay, aisle or car park row at a time.

Common questions from West Thorney clients
Is West Thorney too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Does the sea air around West Thorney change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Can a joint be sealed if the edges are broken?
The edges have to be sound. If they’re damaged, we will say so before any sealing, so the new seal has something to grip.
Are expansion joints and movement joints the same thing?
The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped and the way they’re sealed is similar.
What will the job cost?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Building owners, agents and FMs in West Thorney
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Cracking or settlement that calls for an engineer’s assessment
- Leaks coming from the membrane rather than the joint seal
- Concrete or masonry repairs along the arrises
If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Surfaces we seal
- Brickwork movement joints
- Podiums and floor movement joints

Cost factors for movement joints
