Why it’s worth doing now in Knockholt
A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints before or alongside any coating work. Older rural buildings around Knockholt move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

Looking after the joints
A few simple habits keep the new joints working:
- Tell us about strong cleaning chemicals before we quote
- Walk the main routes and inspect joint lines on a regular cycle
- Clear packed debris from open joints regularly
- Hold traffic back until the product has cured
Problems inside the 12-month guarantee period are ours to put right. Beyond that, an inspection once or twice a year catches failing joints early.
Grit in an open joint does damage every time a wheel crosses it. Filling it ends that cycle before it becomes a repair.
Cost factors for floor joints
What shapes the price:
- The product specified
- Whether the work must be split into stages
- Backing rod, priming and other preparation
- Access and working height
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Details that help us quote
A few photographs plus some basic facts will normally do. Please tell us:
- Whether an asbestos survey exists
- The product your specification calls for
- A wide shot and a close-up of the area
- Drawings or a marked-up plan, if available
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email us.

- Wide or random cracking that suggests a structural issue
- Uneven floors that need grinding or levelling
If you are not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

- Broken arrises where pallet trucks cross
- Open saw cuts full of debris

Questions we are asked in Knockholt
Is Knockholt off your patch?
No. Places such as Knockholt are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is North Downs Business Park, near Knockholt, within your area?

Do you repair broken joint edges?
Filling against broken edges doesn’t last. If the arrises have spalled, we’ll say they need repair before filling and set out how that affects the job.
Is the floor joint work guaranteed?
Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Floors, slabs and movement joints in Knockholt
Knockholt sits in one of the drier corners of the country, the South East. 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. Knockholt lies roughly 16 miles out from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.
For buildings at a park such as North Downs Business Park, 2.2 miles east of Knockholt, brick and panel movement joints are easy to forget until one leaks.
