Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Plan for a top-up on newer floors
- Stop forks and pallets being dragged across joints
- Check joint lines on busy aisles regularly
- Respect the cure time before traffic returns
If a joint we filled starts to break up within 12 months, tell us and we will arrange a look. After that, a check before your busiest period keeps small repairs small.
Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.
About our floor joint sealing in Haverstock
Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so we will tell you if the joint edges need repairing first and leave that decision with you. We work on joints along racking aisles, saw-cut induced joints and retail and showroom floors, and what we are called in for most is chipped and spalling edges along forklift routes and flexible sealant torn out by wheels. A single leaking joint is often how a building in Haverstock first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, call 01277 525 020 or email the details over and we will arrange a return visit.

Why deal with it now?
Open joints are where dirt collects, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Flush, filled joints leave nothing for cleaners to dig out. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What the job involves on each surface
Construction joints
Day joints vary, with or without armoured edges. We’ll tell you if the edges or any armouring look like they need attention before filling.
Loading bays and dock areas
At loading bays, product choice has to suit the loads, the temperature and the wet. Curing times also have to fit around deliveries.
Where floor joints take the most wear near Haverstock
London car parks, loading bays and podium decks often can’t close for long, which is why we work a few bays at a time. Haverstock has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Office parks like Regis Road Business Park (0.9 miles north-east of Haverstock) have decks, ramps and clad elevations whose joints take movement every day. At a retail site such as O2 Centre (0.8 miles west of Haverstock), trolleys, cages and cars run over floor and slab joints all day. For estates staff at a university like Regent's University London (1.4 miles south of Haverstock), building and paving joints are part of the planned maintenance list.

What else we do in Haverstock
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Common questions from Haverstock clients
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.
Can you take on a job at a hospital such as Royal Free Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
When can forklifts run over new joint filler?
Cure times vary with the product and the conditions. We’ll give you a time for each zone when we agree the phasing.
Can the warehouse stay open while you work?
Typically only the zone we’re working in has to close. Each zone reopens when the product can take traffic and the next zone follows.
Is colour matching possible?
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’ll confirm the colours available for the specified product.
Is it normal for joint filler to separate?
Young concrete carries on shrinking for a long time and a stiff filler can separate down one side. A top-up normally puts it right.
