Expansion joint sealing in Dunk's Green, done properly
Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. We work on blockwork control joints, car park decks and ramps and brickwork movement joints, and the usual reasons a site gets in touch are torn sealant in brick or block movement joints and weathered movement joint sealant that no longer flexes. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Dunk's Green, that means joint design, primers and backing rod as standard.
Around smaller places such as Dunk's Green, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Different surfaces, different methods
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints, or we visit if they don’t show enough.
Other services in Dunk's Green
Leave it or put it right?
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind and repeated access costs add up. Where it helps, we quote both options. Halls, stores and units around places like Dunk's Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

- One number for every site we cover

Expansion joint sealing in Dunk's Green: the local picture
Dunk's Green sits in one of the drier corners of the country, the South East. 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. The 3 miles around Dunk's Green take in two named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Hospital campuses such as Tonbridge Cottage Hospital, 5.3 miles to the south of Dunk's Green, grow in stages, leaving movement joints wherever new blocks meet old. Schools like Plaxtol Primary School often have long brick elevations with movement joints that age quietly. Phasing is what makes joint work possible on busy sites such as Bourne Enterprise Centre (2.9 miles north of Dunk's Green): one bay, aisle or car park row at a time.

Questions about Dunk's Green
Is a smaller place like Dunk's Green outside your area?
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.
Is hospital work, at somewhere like Tonbridge Cottage Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Crumbling edges that would give a new bead nothing sound to grip
- Leaks coming from the membrane rather than the joint seal
- Cracking or settlement that calls for an engineer’s assessment
If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Dunk's Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- 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
- Flag any permit to work we’ll need
- Tell us your opening times and when work is allowed
- Share the asbestos register for older buildings
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
