Expansion joint sealing for commercial buildings in New Cross
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. The enquiries we see most involve joints where the bead has lost adhesion and hardened, cracked sealant on exposed facades, on precast concrete panel joints, cladding panel joints and car park decks and ramps. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in New Cross, that means joint design, primers and backing rod as standard.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Our process
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- 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
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits
- Send any specification or drawings in advance
Getting a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.
Advice
Also in New Cross
Quoting for work in New Cross
Each job is priced on its own details. The main factors are:
- The size and state of each joint
- How accessible the joints are
- Site requirements such as inductions and permits
- Whether old sealant has to be cut out first
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Whether the building will be occupied during the work
- Any specification or named product
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or phone 01277 525 020 or use the quote form if you’d rather talk the job through.
When to bring in a specialist
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.
Redoing a failed joint usually costs more than getting it right at the outset, 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.
Honest limits
We check first that sealant really is the fix. It won’t put right:
- Crumbling edges that would give a new bead nothing sound to grip
- Joints too narrow for the movement, which need redesigning by the engineer
- Waterproofing layers buried beneath the sealant
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think before you book.

Floors, slabs and movement joints in New Cross
Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured. New Cross 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.
For an estate such as University Hospital Lewisham, 1.4 miles to the south-east of New Cross, the joints in ramps, decks and long building elevations all need attention over time. University campuses such as University of Greenwich - Greenwich Campus, 1.4 miles north-east of New Cross, have car parks, paved walkways and building elevations with movement joints. At places like Brookmarsh Industrial Estate (0.9 miles north-east of New Cross), joints are sealed a section at a time so operations carry on.
New Cross is about 3 miles south-east of London, in Greater London. Commercial clients in New Cross use us for work on movement joints. 764 places across Greater London fall within our area, New Cross among them.

How the job changes by surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, typically low-modulus, with backing rod setting the depth.
