Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Proprietary pre-formed expansion joint systems
- Joints too narrow for the movement, which need redesigning by the engineer
- Leaks coming from the membrane rather than the joint seal
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
What we seal
- Cladding panel joints

Expansion joint sealing for commercial buildings in Hadley Wood
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on brickwork movement joints, car park decks and ramps and blockwork control joints, and what we’re called in for most is torn sealant in brick or block movement joints and sealant pulling off the joint face. Facilities teams, main contractors and managing agents in Hadley Wood tend to want the same three things: 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. Planning a job in Hadley Wood means thinking about access, loading times and the ULEZ as well as the joints.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
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. That’s why many clients bring in a specialist from the beginning.

What else we do in Hadley Wood
Warehouse floors and decks around Hadley Wood
In London, decks, bays and service yards normally have to keep running, so the work is broken into short sections agreed with the building manager. Hadley Wood 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.
At a retail site such as Spires Shopping Centre, which lies west of Hadley Wood, trolleys, cages and cars run over floor and slab joints all day. In a school such as Livingstone Primary and Nursery School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Why act early in Hadley Wood
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind, and a second visit means paying for access again. We can price a patch and a full reseal side by side. In Hadley Wood, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Common problems we fix in Hadley Wood
Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.
Clients normally get in touch after noticing something like this:
- Joints where the bead has lost adhesion
- Expansion joints filled with dirt and stones
- Hardened, cracked sealant on exposed facades
- Water getting into the wall through a failed joint
Hospitals like Potters Bar Community Hospital (1.8 miles north of Hadley Wood) have multi-storey or surface car parks whose joints carry vehicles round the clock.
What your quote should include
- The terms of the workmanship guarantee
- How the existing material will be dealt with
- Whether their applicators hold CSCS cards
- Do they follow the manufacturer’s priming guidance?
How a job runs
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 the sealant is tooled off neatly. 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.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed
- For older buildings, check the asbestos register before work
Quotes
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Surface by surface
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.
Questions we’re asked in Hadley Wood
Is a hospital such as Potters Bar Community Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you work in London buildings with loading restrictions?
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
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What sealant do you use in movement joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class.
