About our expansion joint sealing in Hanger Hill
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve brittle, chalky sealant on external joints and movement joints with split or torn sealant, on car park decks and ramps, precast concrete panel joints and podiums and floor movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hanger Hill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Hanger Hill, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions about Hanger Hill
Do you cover business parks and estates near Hanger Hill, such as Concord Business Centre?
Yes, sites like Concord Business Centre are within our area, along with the rest of Hanger Hill. A few photos and the unit address let us price the work.
Can you work on a hospital site such as Cygnet Hospital Ealing?
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.
How long does movement joint sealing take?
It usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Cure time before reopening is confirmed on the day.
Can you work on car park ramps and decks?
Yes. Let us know the opening hours and which levels or bays have to stay available.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
Common problems we fix in Hanger Hill
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.
What tends to prompt an enquiry:
- Layers of sealant in a movement joint
- Spalled or broken joint edges in floors and decks
- Leaks through car park deck joints onto the level below
- Torn sealant in brick or block movement joints
At a retail site such as Kew Retail Park, which lies south of Hanger Hill, trolleys, cages and cars run over floor and slab joints all day.

From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Share the asbestos register for older buildings
- Agree which areas must stay open

Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Crumbling edges that would give a new bead nothing sound to grip
- Waterproofing layers buried beneath the sealant
- A joint that has to be widened or re-detailed before it can work
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think.

How the job changes by surface
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.
