How we handle floor joint sealing in Upper Street
It isn’t only heavy industry. Shops, showrooms and trade counters have joints that take trolleys, foot traffic and scrubber-driers, and an open, grimy joint line looks poor as well as catching wheels. A neat, flush fill makes the floor easier to clean and look after. If you are dealing with unfilled floor joints collecting dirt and grit and old filler gone hard, cracked or loose, we can help. A single leaking joint is often how a building in Upper Street first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places such as Upper Street, 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What happens if it’s left?
An open joint is a modest filling job while its edges are sound. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled which means more downtime in that zone. Older rural buildings around Upper Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Where floor joints take the most wear near Upper Street
Rainfall across the South East, Upper Street included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in. Less than 3 miles from Upper Street there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
A healthcare site such as Fordingbridge Hospital, 2.5 miles to the south of Upper Street, depends on car parks, ramps and service yards whose joints take traffic all day. In a school such as Breamore Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Locally, jobs take us to sites close to Bat and Ball pub and The Burgate School and Sixth Form. Well-known places in the area include Fordingbridge Museum (2.5 miles south) and Salisbury District Hospital (5.5 miles north).
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Let us know what the floor is cleaned with
- Respect the cure time before traffic returns
- Remind operators to lift rather than drag
- Plan for a top-up on newer floors
Dragged forks and pallets gouge joints and edges alike. Even a well-filled joint can be damaged by steel scraping along it.
Every day an open joint stays full of grit, the edges take more punishment. Filling it ends that cycle while it is still a straightforward job.
Common problems we fix in Upper Street
Oil, laitance, dust and old cleaning chemicals build up inside joints. Without cutting back to sound, clean concrete the new filler can’t stay bonded.
What tends to prompt an enquiry:
- Joint fill separating from the concrete
- Trucks and loads jolting over damaged joints
- Loading bay joints breaking down
- Open saw cuts full of debris
Estates like Arch Farm Industrial Estate, 2 miles south of Upper Street, combine warehouse slabs, yards and loading bays, all with joints under wheels.

Common questions from Upper Street clients
Can you take on a job at a hospital such as Fordingbridge Hospital?
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.
Is Arch Farm Industrial Estate, near Upper Street, within your area?
Yes. We cover Upper Street and the area around it, including industrial estates, business parks and retail parks such as Arch Farm Industrial Estate. Photos and a short description are enough for a first look.
How soon can traffic go back on the floor?
Cure times vary with the product and the conditions. We’ll give you a time for each zone when we agree the phasing.
Should floor joints be filled or sealed?
We decide joint by joint. Hard wheels need edge support, which points to a semi-rigid filler and perimeter or movement joints need flexibility. The quote sets out what goes where.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How the job changes by surface
Flexible floor sealants
Polyurethane sealants suit floor joints with larger movement. They give less edge support than semi-rigid fillers, so they suit lighter traffic or movement joints.
Saw-cut induced joints
Induced joints are sawn into a new slab to control where it cracks. They start narrow and widen as the concrete dries, and on truck routes they need a filler that supports the edges.
