Your questions answered
Will you take on work at estates like Arlington Business Park, close to Nup End Green?
Yes, sites like Arlington Business Park are within our area, along with the rest of Nup End Green. Photos and a short description are enough for a first look.
Can you work on a hospital site such as Lister Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Should floor joints be filled or sealed?
It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. For bigger or phased jobs, we’ll set out a timescale with the quote.
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 the filling isn’t wasted.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
How we handle floor joint sealing in Nup End Green
Not every floor joint we treat is in a warehouse. Shops, showrooms and trade counters have joints that take trolleys, foot traffic and scrubber-driers, where a gappy, dirty joint looks untidy and snags castors. A neat, flush fill makes the floor easier to clean and look after. If you have untidy open joints in a retail unit and brittle joint filler breaking up, we can put it right, on loading bays, joints along racking aisles and retail and showroom floors alike. Whoever orders the work in Nup End Green, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Jobs around smaller places like Nup End Green are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Leave it or put it right?
A floor coating laid over open joints soon cracks along the joint lines. Joints need their own treatment before or alongside any coating work. Converted and older buildings near places like Nup End Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

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.

What we’re called out for in Nup End Green
A slab keeps shrinking for a long time after it is cast, and saw-cut joints give that shrinkage a planned place to crack. As the panels contract, the joints widen so a filler put in early may separate along one side.
If one of these sounds familiar, it’s time for a closer look:
- Drivers complaining about joints on a route
- A gap opening alongside old joint filler
- Joint edges breaking up under truck wheels
- Grimy joint lines spoiling a showroom floor
Across sites such as Horizon Technology Park, 2 miles to the north of Nup End Green, floor and movement joints can be sealed in phases so units keep working.
