Expansion joint sealing in Dunsden Green, done properly
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, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in. The enquiries we see most involve damp inside where a wall movement joint has failed and joints packed with grit and debris, on podiums and floor movement joints, cladding panel joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dunsden Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller community and commercial buildings around Dunsden Green have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. For work around Dunsden Green, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Tell staff and tenants when we will be in
- Send your site hours and access windows
- Send any specification or drawings in advance

General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Joints that move: notes for Dunsden Green
The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. At about 36 miles from central London, Dunsden Green is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
University campuses such as University of Reading, 0.7 miles to the east of Dunsden Green, have car parks, paved walkways and building elevations with movement joints. Schools like St Martin's Catholic Primary School often have long brick elevations with movement joints that age quietly. Hospitals like Royal Berkshire Hospital, 2.9 miles to the south of Dunsden Green, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Maintenance after handover
A few simple habits keep the new joints working:
- Inspect movement joints alongside other routine building checks
- Plan racking layouts so feet don’t land on a joint
- Act on the first tear or lifting edge rather than waiting
- Keep stones and debris out of open joint lines
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.

Questions we are asked in Dunsden Green
Do you cover business parks and estates near Dunsden Green, such as Suttons Business Park?
Yes. Estates, retail parks and business parks around Dunsden Green, Suttons Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Do you take on work at healthcare sites like Royal Berkshire 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.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Why do our movement joints keep failing?
The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Can staff carry on working while you’re here?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
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
- Crumbling edges that would give a new bead nothing sound to grip
- Joints too narrow for the movement, which need redesigning by the engineer
If you are not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Why act early in Dunsden Green
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. We can price a patch and a full reseal side by side. Halls, stores and units around places like Dunsden 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.
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
