Questions about Dunton Green
Is Dunton Green too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work on a hospital site such as Sevenoaks Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email us. Include photos or drawings if you have them.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
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 typically need a polyurethane, and the specification has the final say.
Expansion joint sealing in Dunton Green
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. We work on car park decks and ramps, cladding panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are damp inside where a wall movement joint has failed and car park joints leaking onto vehicles below. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Dunton Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Halls, schools and small commercial buildings near places like Dunton Green have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
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.

Joints that move: notes for Dunton Green
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, while winter salting gets into any joint left open. Dunton Green is about 18 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
At places like Goya Business Park Sevenoaks (1.1 miles east of Dunton Green), joints are sealed a section at a time so operations carry on. For buildings at a park such as Sevenoaks Business Centre, 1.1 miles east of Dunton Green, brick and panel movement joints are easy to forget until one leaks.
Dunton Green is about 1 mile north-west of Sevenoaks, in Kent. Commercial clients in Dunton Green can call on us for movement joints. Dunton Green is one of 931 places we cover in Kent. Our London page has more on work in that area (18 miles or so).

Commercial clients in Dunton Green
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Why deal with it now?
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. Converted and older buildings near places like Dunton Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Why appoint us
- Failed material removed, not covered up
- Over 20 years of commercial sealing
- Colours confirmed for the specified product
- Public liability insurance in place

Cost factors for movement joints
Each job is priced on its own details. The main factors are:
- Which sealant the job calls for
- Phasing around occupants
- Whether old sealant has to be cut out first
- Travel to remote or island sites
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Send us:
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- When you need the work done
- The asbestos register, for older buildings
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or send photos by email.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Dunton Green need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
- Let us know about inductions and permits

What we are called out for in Dunton Green
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.
These are often picked up first by site or facilities staff:
- Chipped joint edges on forklift routes
- Sealant peeling off one face of the joint
- Weathered movement joint sealant that no longer flexes
- Damp inside where a wall movement joint has failed
In a school such as Dunton Green Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Comparing quotes
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
- What the guarantee covers, and for how long
- Whether old or failed sealant will be cut out, not overlaid
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
