Expansion joint sealing in Broadfields Estate
We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it. We work on precast concrete panel joints, brickwork movement joints and podiums and floor movement joints, and what we’re called in for most is expansion joints split through the centre of the bead and arrises breaking up along floor joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Broadfields Estate is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Broadfields Estate, as everywhere in London, access, loading and the ULEZ all come into the plan.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What the job involves on each surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Planning a London job such as one in Broadfields Estate starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- 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.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Arrange parking or a loading space
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000

Advice
Cost factors for movement joints
Each job is priced on its own details. The things that drive the figure:
- Access and working height
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- Specialist products, such as fire-rated or hygienic sealants
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- The type of building and who uses it
- A wide shot and a close-up of the area
- Specification clauses that apply
- Asbestos survey details if the building is older

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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. That’s why many clients bring in a specialist from the beginning.
Where floor joints take the most wear near Broadfields Estate
The 3 miles around Broadfields Estate 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. Basement car parks and service yards in London tend to be in use all working day, so joints are sealed in sections with each area handed back once cured.
Centres like Broadwalk Centre, 1 mile south of Broadfields Estate, have mall floors and service decks whose joints carry steady traffic. Phasing is what makes joint work possible on busy sites such as Mill Hill Industrial Estate (1.7 miles south-east of Broadfields Estate): one bay, aisle or car park row at a time.

What we are called out for in Broadfields Estate
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 so backing is set before sealing.
Site and facilities staff are often the first to spot these:
- Car park joints leaking onto vehicles below
- Debris jammed in movement joints
- Spalled or broken joint edges in floors and decks
- New sealant over old, now failing
Warehouse floors on estates like Mill Yard Industrial Estate (1.6 miles south of Broadfields Estate) carry pallet trucks and forklifts over every saw-cut joint.

Broadfields Estate: questions and answers
Does your area include sites such as Mill Yard Industrial Estate, near Broadfields Estate?
Yes, sites like Mill Yard Industrial Estate are within our area, along with the rest of Broadfields Estate. Send details of the unit and the work through our quote form for a quick quote.
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. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Can you seal joints in cold or wet weather?
Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. We agree a revised date with you.
Are expansion joints and movement joints the same thing?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
