Questions about Eltham
Will you take on work at estates like Green Lane Business Park, close to Eltham?
Yes. Estates, retail parks and business parks around Eltham, Green Lane Business Park among them, are all within reach. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you take on a job at a hospital such as Eltham Community Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you work in Eltham?
Yes. We cover Eltham and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or email a schedule or drawings.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Should floor joints be filled or sealed?
The answer comes from the traffic and the joint’s movement. Forklift routes generally call for a semi-rigid filler that holds the arrises and joints with more movement take a flexible sealant.
Why has the filler pulled away from one side?
Separation typically comes from slab shrinkage, poor preparation or the wrong product. We diagnose the cause before suggesting a fix.

Where floor joints take the most wear near Eltham
Basement car parks and service yards in London tend to be in use all working day, so joints are sealed in sections with each area handed back once cured. The 3 miles around Eltham take in two named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Phasing is what makes joint work possible on busy sites such as Chiltonian Industrial Estate (2 miles west of Eltham): one bay, aisle or car park row at a time. Parks like Green Lane Business Park, 0.7 miles south-east of Eltham, combine paved areas, car parks and building elevations, each with joints that move.
Eltham is about 7 miles west of Dartford, in Greater London. Our applicators travel to Eltham for work on floor joints, handled exactly as we handle every other area. Our Greater London coverage takes in 764 places. For work in that direction, see our London page, about 8 miles away.

What else we do in Eltham
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Make joint checks part of your floor inspections
- Allow for topping up joints as a new slab settles
- Keep grit out of unfilled joints in the meantime
- Photograph any joint that starts to chip
Walk the main truck routes every few months and look along the joint lines. Look for separation down one side, new chips in the arris and debris gathering and keep photos so changes are easy to compare.
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.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Eltham can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Each area is assessed for joint width, arris damage and the wheels that cross it.
- A fixed quote follows, listing the treatment for each area and the order of work.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- Filler or sealant goes in to the right depth and is finished flush with the slab.
- The area is handed back once it has cured enough to take traffic.
Getting the site ready
- Send your site hours and access windows
- Point out any areas we must not close
- Flag any permit to work we will need

What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
- Cracks across panels caused by settlement or overload
- Worn screed or surface finishes
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly before you book.
What we seal
- Construction joints
- Joints along racking aisles
- Retail and showroom floors
- Forklift and pallet-truck routes
- Loading bays
- Saw-cut induced joints
Do you need floor joint sealing in Eltham?
Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. Packed debris acts like a wedge every time a wheel crosses, speeding up the damage.
Site and facilities staff are often the first to spot these:
- Drivers complaining about joints on a route
- Open saw cuts full of debris
- A gap opening alongside old joint filler
- Soft sealant dragged out of trafficked joints
Hospital campuses such as Eltham Community Hospital, under half a mile to the north of Eltham, grow in stages, leaving movement joints wherever new blocks meet old.
