Expansion joint sealing for commercial buildings in St Margarets
For movement joints in St Margarets, photographs and approximate lengths are the best start. We’ll come and look where photographs don’t show enough. You can also speak to us on 01277 525 020 or email us to talk the joints through. We work on car park decks and ramps, cladding panel joints and blockwork control joints, and what we’re called in for most is arrises breaking up along floor joints and water getting into the wall through a failed joint. A single leaking joint is often how a building in St Margarets 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.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In St Margarets, as everywhere in London, access, loading and the ULEZ all come into the plan.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Expansion joint sealing in St Margarets: the local picture
The 3 miles around St Margarets take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards normally have to keep running, so we seal in sections and hand areas back as each cures.
Campuses like University of London (to the north-west of St Margarets) mix old and new buildings, with movement joints wherever they meet. Retail sites such as Ivybridge Retail Park, 0.5 miles west of St Margarets, have car park, service yard and shop floor joints under constant traffic. Sites like West Middlesex Hospital, 0.9 miles north of St Margarets, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Joints too narrow for the movement, which need redesigning by the engineer
- Concrete or masonry repairs along the arrises
- Leaks coming from the membrane rather than the joint seal
If in doubt, ring 01277 525 020 or email us and we’ll say what we think before you book.
Surfaces we seal
- Blockwork control joints
- Brickwork movement joints
- Podiums and floor movement joints
- Car park decks and ramps
- Cladding panel joints
- Precast concrete panel joints
How the job changes by surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.
Common questions from St Margarets clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Can you work at a site such as Ivybridge Retail Park, by St Margarets?
Yes, sites like Ivybridge Retail Park are within our area, along with the rest of St Margarets. Send details of the unit and the work through our quote form for a quick quote.
Can staff carry on working while you’re here?
Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can a joint be sealed if the edges are broken?
Spalled edges need repairing before a new seal will last and we will flag every length affected. Sealing over them leads to early failure.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Look over external and deck joints after a hard winter
- Inspect movement joints alongside other routine building checks
- Keep product details with the building records for the next reseal
- Act on the first tear or lifting edge rather than waiting
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. 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.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Send any specification or drawings in advance
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
