A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or send photos by email to discuss it first.
Expansion joint sealing for commercial buildings in Lisson Grove
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. If you have chipped joint edges on forklift routes and hardened, cracked sealant on exposed facades, we can help, whatever the surface. Whoever orders the work in Lisson Grove, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Lisson Grove, as everywhere in London, access, loading and the ULEZ all come into the plan.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Lisson Grove can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Flag any permit to work we’ll need
- Confirm the product named in the specification
- Tell us which areas need to stay in use

When to call us in Lisson Grove
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.
It’s worth sending us details if you spot any of the following:
- Water getting into the wall through a failed joint
- Torn sealant in brick or block movement joints
- Expansion joints filled with dirt and stones
- Weathered movement joint sealant that no longer flexes
Sites like Nightingale Hospital (to the south-east of Lisson Grove) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Comparing quotes
- Can the work be phased to keep areas open?
- Is the sealant right for the movement and the substrate?
- Health and safety accreditation such as CHAS
- Will failed sealant be removed rather than covered?
Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What you get with us

Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Crumbling edges that would give a new bead nothing sound to grip
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If in doubt, phone 01277 525 020 or email the details over and we will say what we think.
Surfaces we seal

FAQs: Lisson Grove
Does your area include sites such as The Quadrant Business Centre, near Lisson Grove?
Yes. Estates, retail parks and business parks around Lisson Grove, The Quadrant Business Centre among them, are all within reach. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is a hospital such as Nightingale Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What do you charge?
There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
Which product is best for expansion joints?
We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
