How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Longfield Hill can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- You get a fixed quote with the product and the phasing set out.
- We remove failed material and packed debris until sound concrete is exposed on both faces.
- We vacuum each run and prime it if the chosen product requires a primer.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- The area is handed back once it has cured enough to take traffic.
Preparing the site
- Arrange parking or a loading space
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Advice
General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Your questions answered
Do you cover business parks and estates near Longfield Hill, such as Fawkham Business Park?
Yes. We cover Longfield Hill and the area around it, including industrial estates, business parks and retail parks such as Fawkham Business Park. Send details of the unit and the work through our quote form for a quick quote.
Is hospital work, at somewhere like Gravesham Community Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it.
What happens if the joint edges are damaged?
We check the edges as part of the survey. Where they have broken away, we will tell you before quoting the filling, so nothing is filled that won’t hold.
Is it normal for joint filler to separate?
It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We diagnose the cause before suggesting a fix.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- A floor that is out of level for the racking or trucks
- Broken concrete either side of the joint
- A failing floor coating, which is a flooring contractor’s job
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Signs you need floor joint sealing in Longfield Hill
A slab keeps shrinking for a long time after it is cast, and the saw cuts are there so it cracks in straight, controlled lines. As the panels contract, the joints widen, and a filler placed early can part company with one face.
Look out for the following:
- Flexible sealant torn out by wheels
- Joint fill separating from the concrete
- Untidy open joints in a retail unit
- Failing joints at loading bays and dock doors
Across sites such as Bowes Industrial Centre, 2.1 miles to the south-east of Longfield Hill, floor and movement joints can be sealed in phases so units keep working.
What your quote should include
- Their public liability cover
- What site paperwork they can supply
- How long is the guarantee, and what does it include?
- Are they CHAS accredited or on Constructionline?
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Ask drivers not to drag forks or pallets
- Mention any aggressive cleaning regime at quote stage
- Hold traffic back until the product has cured
- Keep photos of joints that look like they’re failing
Once cured, the joints get cleaned along with the slab. Tell us about aggressive cleaning products or hot washing at quote stage so we choose something that tolerates them.
Treating joints while the arrises are sound keeps the work simple. After the edges go, repairs come into it and that takes longer and closes areas for longer.
Slabs, ramps and loading bays in Longfield Hill
The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open. At least three named trading, business or retail sites lie within about 3 miles of Longfield Hill. Their warehouses, yards and car parks are exactly where joints take the most punishment.
