Expansion joint sealing in West Dean
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we’ll confirm the choice in the quote. Site teams most often ask us about damp inside where a wall movement joint has failed and expansion joints filled with dirt and stones, on car park decks and ramps, brickwork movement joints and podiums and floor movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in West Dean is the same: the right product in a properly prepared joint.
Smaller community and commercial buildings around West Dean have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Every job we finish is backed by a 12-month workmanship guarantee, in West Dean as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Proprietary pre-formed expansion joint systems
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- A joint that has to be widened or re-detailed before it can work
If in doubt, phone 01277 525 020 or send photos by email and we will say what we think.

Looking after the joints
Once the work is signed off, these steps help:
- Avoid parking heavy plant or pallets on joint lines
- Keep scrapers and ploughs from dragging across joint sealant
- Clear dirt from joint lines during routine cleaning
- Note which joints were done, when, and with what
Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Sealing early protects the edges.
West Dean: questions and answers
Is West Dean off your patch?
No. Places such as West Dean are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Would you work within a site like Chichester Centre?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Site staff or a sealant specialist?
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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Work for main contractors and building owners
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.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Traffic, movement and joints around West Dean
West Dean 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, while winter salting gets into any joint left open. West Dean is about 51 miles from central London.

Hospitals like Chichester Centre (4.1 miles south of West Dean) have multi-storey or surface car parks whose joints carry vehicles round the clock. In a school such as West Dean CofE Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

How a job runs
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. If others near West Dean need work, visits can be combined. You will have a fixed quote before work starts.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- Point out any areas we must not close
- Send any specification or drawings in advance

Different surfaces, different methods
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler.
