Expansion joint sealing in West Kingston
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on cladding panel joints, podiums and floor movement joints and precast concrete panel joints, and what we are called in for most is expansion joints filled with dirt and stones and spalled or broken joint edges in floors and decks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in West Kingston, preparation and product choice get the time they need.
For a site near West Kingston, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Concrete or masonry repairs along the arrises
- Damaged metal nosings or cover plates over a joint
- Movement on a scale no sealant is meant to absorb

Traffic, movement and joints around West Kingston
West Kingston is within about 1 mile of the coast. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
On industrial estates such as Rustington Trading Estate, which lies north-west of West Kingston, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Schools like East Preston Infant School often have long brick elevations with movement joints that age quietly.
West Kingston is about 3 miles east of Littlehampton, in West Sussex. Any commercial site in West Kingston is covered. We work across 373 places in West Sussex. We also cover Brighton, around 15 miles from West Kingston.

When to bring in a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around West Kingston 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.
- 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.
Preparing the site
- Warn occupants and staff about the work
- Send your site hours and access windows
- Clear stock, furniture or equipment away from the joints

Looking after the joints
For the best life from the joints:
- Brief car park operatives to protect joint lines during winter clearance
- Keep product details with the building records for the next reseal
- Inspect exposed joints once the cold weather has passed
- Keep stones and debris out of open joint lines
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. A sound seal keeps the joint working.
Your questions answered
Do you take on work at healthcare sites like Zachary Merton Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is West Kingston off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email us. Include photographs or drawings if you have them.
Can a joint be sealed if the edges are broken?
Sound edges are essential. If they’re damaged, we will say so before any sealing.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When to call us in West Kingston
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again.
Typical triggers for a call:
- Brittle, chalky sealant on external joints
- Layers of sealant in a movement joint
- Chipped joint edges on forklift routes
- Damp inside where a wall movement joint has failed
Another example is Goring Business Park (2.2 miles east of West Kingston), where floors and yards would be done in stages around the occupiers.
What your quote should include
- How the joint faces will be prepared and primed
- Whether their applicators hold CSCS cards
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?
