Expansion joint sealing in Duncton, done properly
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. The enquiries we see most involve weathered movement joint sealant that no longer flexes and sealant peeling off one face of the joint, on podiums and floor movement joints, precast concrete panel joints and brickwork movement joints. Facilities teams, main contractors and managing agents in Duncton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Duncton, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Duncton, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, 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.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site

- Confirm the product named in the specification

Floors, slabs and movement joints in Duncton
Rainfall across the South East, Duncton included, is lower than in many 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. Duncton is about 45 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.
A healthcare site such as Midhurst Community Hospital (to the north-west of Duncton) depends on car parks, ramps and service yards whose joints take traffic all day.
Duncton is about 10 miles north-east of Chichester, in West Sussex. Across the GU28 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 373 places across West Sussex fall within our area, Duncton among them. Portsmouth is covered too, around 22 miles from Duncton.
If you need expansion joint sealing in GU28, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Around Duncton

Aftercare for building managers
To get the most from the new sealant:
- Check joints after long freezing spells
- Act on the first tear or lifting edge rather than waiting
- Leave barriers in place until fresh joint sealant has cured
- Raise snow-clearing blades over deck joints where possible
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.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.
What the job involves on each surface
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.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
Commercial clients in Duncton
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Duncton can sit alongside others in a wider programme.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Do you need expansion joint sealing in Duncton?
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way unless width and product are reviewed.
What tends to prompt an enquiry:
- Leaks through car park deck joints onto the level below
- Torn sealant in brick or block movement joints
- Joints where the bead has lost adhesion
- Joints packed with grit and debris
For a school such as Duncton CofE Junior School, playground and building joints can be done in the holidays.

Common questions from Duncton clients
Is Duncton off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Does a site in Duncton have to shut while its joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
What causes movement joint sealant to fail?
The way it has failed typically tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
Can staff carry on working while you are here?
Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Can a joint be sealed if the edges are broken?
Spalled edges need repairing before a new seal will last, and we will point out where that’s the case. Sealing over them leads to early failure.
Quoting for work in Duncton
To price the job, we consider:
- Working within restricted access windows
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Good information means a firmer quote. When you get in touch, include:
- Drawings or a marked-up plan, if available
