Floor joint sealing in Romford, done properly
Forklifts and pallet trucks are hard on open joints. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. Filling the joint properly gives the edges back their support. It also smooths the route for drivers and stock. If you’re dealing with grimy joint lines spoiling a showroom floor and unfilled floor joints collecting dirt and grit, we can help, whatever the surface. Most enquiries from Romford start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Romford, as everywhere in London, access, loading and the ULEZ all come into the plan.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What happens if it’s left?
Duct tape or a general builders’ sealant can seem to buy some time. None of it is designed for wheel loads, and it normally ends up dragged across the floor. The right filler or sealant saves doing it twice. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
A quote for floor joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What we’re called out for in Romford
A soft, flexible sealant on a forklift route can’t hold the arrises up and the edges fail regardless. It can go the other way too: a stiff filler in a joint that keeps moving splits or comes away from the sides.
What tends to prompt an enquiry:
- Loading bay joints breaking down
- Chipped and spalling edges along forklift routes
- Flexible sealant torn out by wheels
- Cracked and crumbling joint fill
For a store at a site such as Rom Valley Retail Park (0.5 miles south of Romford), the service yard and goods-in area are where joints break down first.
What to look for in a quote
- How joint depth will be controlled
- Can the work be phased to keep areas open?
- Who will actually carry out the work
- What level of public liability insurance do they hold?
Different surfaces, different methods
Flexible floor sealants
Polyurethane sealants suit floor joints with larger movement. They don’t hold the arrises up as firmly as a semi-rigid fill so they are used where movement matters more than wheel load.
Construction joints
Construction joints, sometimes called day joints, mark where one pour ended and the next began. They can move more than saw cuts and that shapes the choice of filler or sealant.
Our process
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 the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in Romford 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.
- You get a fixed quote with the product and the phasing set out.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- We vacuum each run and prime it if the chosen product requires a primer.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- We tell you when each zone can carry trucks again and move on to the next.
Preparing the site
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs

Retail centres such as Romford Shopping Hall, less than half a mile north of Romford, have floors, service yards and car parks with joints under constant traffic.

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Sweep debris out of open joints until they can be filled
- Record damaged joints with a photo and a location
- Tell us about strong cleaning chemicals before we quote
- Check joint lines on busy aisles regularly
Keep traffic off fresh joints until the time we give you and it pays to stick to it. Cones or barriers stop the first driver cutting the corner.
While the concrete edges are intact, it’s a filling job. After the edges go, repairs come into it and that takes longer and closes areas for longer.
Questions about Romford
Do you cover business parks and estates near Romford, such as Rom Valley Retail Park?
Yes. Estates, retail parks and business parks around Romford, Rom Valley Retail Park among them, are all within reach. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you work on a hospital site such as Queens Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is it normal for joint filler to separate?
On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. It is typically dealt with by topping up.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What site paperwork can you supply?
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.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
