Floor joint sealing for Fortis Green sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We look at joint widths, edge condition and the traffic on each route.
- The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- Each phase reopens when the product is ready for wheels, then we start the next.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Tell us what induction or permit system the site runs
- Tell us your opening times and when work is allowed

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Floor joint sealing in Fortis Green, done properly
For sites in Fortis Green and across Greater London, the process is short: send details, get a fixed quote, we seal, and the work is guaranteed. Approximate joint lengths, a few photographs and a floor plan are enough for a quick quote and a visit can be arranged where that is easier. Most enquiries involve chipped and spalling edges along forklift routes and soft sealant dragged out of trafficked joints, across joints along racking aisles, construction joints and forklift and pallet-truck routes. Whether you call it commercial sealant work, mastic application or joint sealing, in Fortis Green it comes down to the same thing: the right product in a properly prepared joint.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Fortis Green, as everywhere in London, access, loading and the ULEZ all come into the plan.
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.

Common problems we fix in Fortis Green
Left open, joints fill with grit, wrap and wood fragments. Packed debris acts like a wedge every time a wheel crosses so the arrises break sooner.
It’s worth sending us details if you spot any of the following:
- Failing joints at loading bays and dock doors
- Brittle joint filler breaking up
- A gap opening alongside old joint filler
- A rough ride across broken joints
Retail sites such as Friern Bridge Retail Park, 1.4 miles to the north of Fortis Green, have car park, service yard and shop floor joints under constant traffic.
What to look for in a quote
- Do they follow the manufacturer’s priming guidance?
- The named product and why it was chosen
- Health and safety accreditation such as CHAS
- Whether their applicators hold CSCS cards
Traffic, movement and joints around Fortis Green
At least three named trading, business or retail sites lie within about 3 miles of Fortis Green. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. 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.
Phasing is what makes joint work possible on busy sites such as Brunswick Industrial Estate (2 miles north of Fortis Green): one bay, aisle or car park row at a time. A healthcare site such as Nuffield Health Highgate Hospital (to the south of Fortis Green) depends on car parks, ramps and service yards whose joints take traffic all day.

When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Your questions answered
Is a hospital such as Nuffield Health Highgate Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you take on jobs in Fortis Green where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Is the floor joint work guaranteed?
Every job has our 12-month guarantee. It applies to our workmanship rather than structural movement or accidental damage.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can the sealant be colour-matched?
Often, 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.
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 do we get a quote for floor joints?
A rough joint length, a few photographs and a site plan are usually enough for a quick quote. We can visit where that helps, and you can speak to us on 01277 525 020 or send photos by email to arrange it.
How the job changes by surface
Saw-cut induced joints
Saw cuts are made soon after the slab is cast so shrinkage cracks follow a line. They start narrow and widen as the concrete dries, and on truck routes they need a filler that supports the edges.
Isolation joints at walls and columns
We plan column and wall joints around racking and fixed plant so nothing has to move unexpectedly.
Looking after the joints
A few simple habits keep the new joints working:
- Sweep debris out of open joints until they can be filled
- Make joint checks part of your floor inspections
- Tell us about strong cleaning chemicals before we quote
- Plan for a top-up on newer floors
Dragged forks and pallets gouge joints and edges alike. Steel tines will mark a good joint over time if it keeps happening.
Treating joints while the arrises are sound keeps the work simple. Once they have broken away, edge repair comes first, with more downtime and more disruption.
