Questions about Little Portugal
Do you cover business parks and estates near Little Portugal, such as Handel Business Centre?
Yes. We cover Little Portugal and the area around it, including industrial estates, business parks and retail parks such as Handel Business Centre. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Do you take on jobs in Little Portugal where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What causes movement joint sealant to fail?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing, because the fix differs.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Expansion joint sealing for commercial buildings in Little Portugal
A movement joint only works while its seal does. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on car park decks and ramps, brickwork movement joints and cladding panel joints, and the usual reasons a site gets in touch are expansion joints filled with dirt and stones and car park joints leaking onto vehicles below. A specialist sealant contractor works differently from a general builder: on jobs in Little Portugal, preparation and product choice get the time they need.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Little Portugal, as everywhere in London, access, loading and the ULEZ all come into the plan.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- 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 you’re not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer.

Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- 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.
Before we start on site
- Make sure the joints can be reached
- Flag any permit to work we’ll need
- Warn occupants and staff about the work

Why deal with it now?
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Floors, slabs and movement joints in Little Portugal
Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures. The 3 miles around Little Portugal take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
For an estate such as Lambeth Hospital, 0.6 miles south of Little Portugal, the joints in ramps, decks and long building elevations all need attention over time.

What affects the price in Little Portugal
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Location, for remote and island sites
- The size and state of each joint
- How much existing material needs removing
- Phasing around occupants
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- When you need the work done
- Any specification or named product
- Drawings or a marked-up plan, if available
- Access details, including height
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Maintenance after handover
After handover, these steps help:
- Include every elevation and deck joint in periodic inspections
- Act on the first tear or lifting edge rather than waiting
- Brief car park operatives to protect joint lines during winter clearance
- Keep traffic off new joints until the cure time is up
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.
