Different surfaces, different methods
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement, and tell you if edges need repairing first.
How we handle expansion joint sealing in Clapham Junction
For movement joints in Clapham Junction, photos and approximate lengths are the best start. We will come and look where photos don’t show enough. You can also call 01277 525 020 or email a schedule or drawings to talk the joints through. We work on precast concrete panel joints, cladding panel joints and podiums and floor movement joints, and the usual reasons a site gets in touch are sealant peeling off one face of the joint and joints packed with grit and debris.

What we’re called out for in Clapham Junction
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.
It’s worth sending us details if you spot any of the following:
- Debris jammed in movement joints
- Brittle, chalky sealant on external joints
- Leaks through car park deck joints onto the level below
- Sealant peeling off one face of the joint
At a retail site such as Brompton Cross District Shopping Centre., which lies north of Clapham Junction, trolleys, cages and cars run over floor and slab joints all day.
What your quote should include
- Their pre-qualification and accreditations
- Their approach to joint depth and backing
- The named product and why it was chosen
- Will RAMS and insurance details be available?

From enquiry to sign-off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Tell us which areas need to stay in use
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Inspect exposed joints once the cold weather has passed
- Report split or peeling joint sealant early
- Keep traffic off new joints until the cure time is up
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
Common questions from Clapham Junction clients
Do you take on work at healthcare sites like Chelsea and Westminster Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Parkfield Industrial Estate, close to Clapham Junction?
Yes. Our area takes in Clapham Junction and its surroundings, with estates and business parks such as Parkfield Industrial Estate included. Photos and a short description are enough for a first look.
Why do our movement joints keep failing?
The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
What about RAMS and site documents?
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.
What will the job cost?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
Can you seal joints in cold or wet weather?
Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside so external dates keep some flexibility.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Clapham Junction can form part of a wider programme.
Traffic, movement and joints around Clapham Junction
At least three named trading, business or retail sites lie within about 3 miles of Clapham Junction. Their warehouses, yards and car parks are exactly where joints take the most punishment. Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager.
Another example is Town Mead Business Centre, which lies north-west of Clapham Junction, where floors and yards would be done in stages around the occupiers. Warehouse floors on estates like Parkfield Industrial Estate (to the north-east of Clapham Junction) carry pallet trucks and forklifts over every saw-cut joint.
