Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
About our floor joint sealing in Dunton Green
Concrete floors in warehouses and factories are cut into bays with saw cuts and day joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. Site teams most often ask us about unfilled floor joints collecting dirt and grit and brittle joint filler breaking up, on construction joints, retail and showroom floors and forklift and pallet-truck routes. Whether you call it commercial sealant work, mastic application or joint sealing, in Dunton Green it comes down to the same thing: the right product in a properly prepared joint.
Smaller community and commercial buildings around Dunton Green have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Dunton Green may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- A floor survey records every joint, its edges and what crosses it.
- You receive a fixed quote showing products and phasing.
- Old fill and packed debris come out until both faces are sound.
- Dust is vacuumed out and primer applied where specified.
- Filler or sealant is placed to depth and finished flush.
- We hand each phase back when it can take traffic.
What we need from you
- Flag any permit to work we’ll need

Related advice
Why deal with it now?
Dirt and spillage gather in open joints, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Filled joints are far simpler to keep clean. For buildings around smaller places like Dunton Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Pricing floor joints depends on quantities, condition and access. Ask us for a fixed quote.

Questions about Dunton Green
Is Dunton Green 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. Where we can, we group nearby jobs to make the most of each trip.
Is hospital work, at somewhere like Sevenoaks Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Why is there a gap next to the joint filler?
On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. It is usually dealt with by topping up.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What if there’s asbestos in the old mastic?
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 if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Honest limits
Honesty saves time and money. Fresh joints won’t solve:
- Unstable slabs moving under traffic
- A failing floor coating, which is a flooring contractor’s job
- Spalled arrises, which need an edge repair first
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly before you book.

Keeping the joints sound
After handover, these steps help:
- Make joint checks part of your floor inspections
- Let us know what the floor is cleaned with
- Record damaged joints with a photo and a location
- Keep grit out of unfilled joints in the meantime
Normal floor cleaning is fine once the product has cured. Tell us about aggressive cleaning products or hot washing at quote stage so the product suits them.
Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder, so it pays to act at the first signs.
