Floor joint sealing in Darenth, done properly
Forklifts and pallet trucks are hard on open joints. Each crossing knocks the unsupported edge, and over time a neat cut turns into a ragged channel. A properly filled joint carries the wheel over and protects both arrises. It also smooths the route for drivers and stock. We work on retail and showroom floors, joints along racking aisles and forklift and pallet-truck routes, and what we’re called in for most is drivers complaining about joints on a route and sealant pulled out along a truck route. A single leaking joint is often how a building in Darenth first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Darenth, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Our process
Occupied buildings need a little choreography. 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. If others near Darenth need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First, the zones and order of work are agreed with you.
- We point out joints whose edges need repairing first.
- We clear each run back to clean concrete.
- We fill the joints with the agreed product, finished level.
- Each area is handed back when ready for traffic.
Getting the site ready
- Tell us what induction or permit system the site runs
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or use the quote form.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Backing rod, priming and other preparation
- Induction, permit and paperwork requirements
- The product specified
- Access and working height
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- What the building is and how it’s used
- Anything awkward about access or site hours
- When you need the work done
- Whether an asbestos survey exists
To get a fixed quote, speak to us on 01277 525 020 or send photos by email with the site address and an outline of the work. You can also send details through our quote form.
Why deal with it now?
Broken joints shake trucks, stock and operators alike. Wheels and bearings wear faster and loads can shift, adding costs nobody plans for. A filled joint takes most of that out. One visit to deal with every failing joint makes more sense than several trips to a place like Darenth. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Treat loading bay joints first if they’re failing
- Hold traffic back until the product has cured
- Clear packed debris from open joints regularly
- Stop forks and pallets being dragged across joints
Normal floor cleaning is fine once the product has cured. If you use strong chemicals or hot-water washing, mention it when we quote so we choose something that tolerates them.
Joint damage starts slowly and then speeds up. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.
FAQs: Darenth
Is hospital work, at somewhere like Darent Valley Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Darenth too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
What guarantee do you give on joint filling?
A 12-month guarantee covers the work we do. It applies to our workmanship rather than structural movement or accidental damage.
How long before trucks can use the joints?
Cure times vary with the product and the conditions. We’ll give you a time for each zone before we start.
Surface by surface
Flexible floor sealants
Movement joints, joints at walls and joints in lightly trafficked areas often take a flexible sealant. Closed-cell backing rod goes in first, keeping the bead shallow and gripping only the two faces.
Loading bays and dock areas
Joints at dock doors need a product that copes with the traffic and the conditions. Curing times also have to fit around deliveries.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Spalled arrises, which need an edge repair first
- Unstable slabs moving under traffic
- Uneven floors that need grinding or levelling
If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think.
