Floor joint sealing in Duncton
Floor joint sealing for us covers warehouse aisles, loading bays, production halls, retail floors and showroom slabs. Pricing depends on the length of joint, how worn the edges are and when we can get in, and the quote is fixed before we mobilise. Site teams most often ask us about chipped and spalling edges along forklift routes and drivers complaining about joints on a route, across retail and showroom floors, forklift and pallet-truck routes and loading bays.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How the job changes by surface
Saw-cut induced joints
Saw cuts are made soon after the slab is cast so shrinkage cracks follow a line. They start narrow and widen as the concrete dries, and on truck routes they need a filler that supports the edges.
Retail and showroom floors
We plan shop-floor work so trading can continue. Tell us your site hours and access windows and we will plan around them.
Common questions from Duncton clients
Do you take on work at healthcare sites like Midhurst Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Is Duncton off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can the warehouse stay open while you work?
Typically only the zone we’re working in has to close. Traffic returns to each zone once it has cured and the next zone follows.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you guarantee industrial floor joints?
Our workmanship carries a 12-month guarantee and the work is covered by public liability insurance.
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 deal with it now?
Dirt and spillage gather in open joints where scrubber-driers can’t get it out. Where the floor is on show or needs to be kept clean, that is a problem. Filled joints are far simpler to keep clean. Around Duncton, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

When to call us in Duncton
Soft sealant in a heavily trafficked joint gives the edges little support and the edges fail regardless. It can go the other way too: a stiff filler in a joint that keeps moving splits or comes away from the sides.
Clients usually get in touch after noticing one or more of the following:
- Dock area joints that have failed first
- Cracked and crumbling joint fill
- Sealant pulled out along a truck route
- A gap opening alongside old joint filler
Sites like Midhurst Community Hospital (to the north-west of Duncton) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Floor joint sealing around Duncton: what changes locally
Duncton lies roughly 45 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Rainfall across the South East, Duncton included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.
In a school such as Duncton CofE Junior School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
