After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Reopen bays and walkways only after the stated cure time
- Act on the first tear or lifting edge rather than waiting
- Brief car park operatives to protect joint lines during winter clearance
- Include every elevation and deck joint in periodic inspections
Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.
On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
Expansion joint sealing for commercial buildings in Headcorn
Brickwork and blockwork walls have vertical movement joints at intervals. 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. Most enquiries involve hardened, cracked sealant on exposed facades and spalled or broken joint edges in floors and decks, on car park decks and ramps, podiums and floor movement joints and cladding panel joints. A specialist sealant contractor works differently from a general builder: on jobs in Headcorn, preparation and product choice get the time they need.
Around places the size of Headcorn, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.

Common questions from Headcorn clients
Can you take on a job at a hospital such as Benenden Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Headcorn off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does the weather affect joint sealing?
Sealing onto a damp surface leads to adhesion failure, so external work waits for suitable conditions. The work is simply moved to the next suitable day.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Why has the sealant in our expansion joints split?
It depends on how the sealant has let go: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
Do you reseal car park expansion joints?
Yes. Let us know the opening hours and which levels or bays have to stay available and we will plan around them.

Joints that move: notes for Headcorn
Headcorn is in the South East, one of the UK’s drier regions. 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. At about 39 miles from central London, Headcorn is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
On industrial estates such as Barradale Farm Industrial Estate, which lies north-west of Headcorn, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Sites like Benenden Hospital, 5.8 miles south of Headcorn, carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Headcorn is about 8 miles south-east of Maidstone, in Kent. We cover commercial sites throughout Headcorn, for single jobs and planned programmes alike. We work across 931 places in Kent, large and small. Sites around London have their own page, about 39 miles away.
We cover the TN27 postcode districts for movement joints. For a building on Station Road, High Street and Knight's Way or nearby, we can quote for movement joints. Nearby places we also cover include Hearnden Green (1 mile north-west), Southernden (2 miles north-east), Swift's Green (2 miles east), Lashenden (2 miles south) and Smarden Bell (2 miles south-east) for movement joints. Bigger towns within reach include Maidstone (8 miles north-west), Ashford (11 miles east), Sittingbourne (13 miles north), Tonbridge (15 miles west), Faversham (15 miles north-east) and Kings Hill (12 miles north-west).

Other landmarks nearby include Sutton Valence Castle (3.2 miles north-west) and Benenden Hospital (5.8 miles south).
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Joints too narrow for the movement, which need redesigning by the engineer
- Waterproofing layers buried beneath the sealant
If you are not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a site in Headcorn, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- 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.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Arrange parking or a loading space
- Flag any permit to work we will need

Advice
Signs you need expansion joint sealing in Headcorn
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Typical triggers for a call:
- Arrises breaking up along floor joints
- Damp inside where a wall movement joint has failed
- Joints packed with grit and debris
- Weathered movement joint sealant that no longer flexes
For a school such as Headcorn Primary School, playground and building joints can be done in the holidays.
What your quote should include

- Proof of insurance
Why it’s worth doing now in Headcorn
A torn seal left alone normally gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. For buildings in places like Headcorn, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

How the job changes by surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.
