Expansion joint sealing for Canning Town sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When to call us in Canning Town

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.

Common reasons buildings call us in:

  • Damp inside where a wall movement joint has failed
  • Joints where the bead has lost adhesion
  • Brittle, chalky sealant on external joints
  • Joints packed with grit and debris

Another example is Manor Road Retail Park (0.9 miles west of Canning Town), where floors and yards would be done in stages around the occupiers.

What to look for in a quote

  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • Is the sealant right for the movement and the substrate?
  • How the joint faces will be prepared and primed

About our expansion joint sealing in Canning Town

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. We’ll tell you if the edges need repairing before sealing. We work on blockwork control joints, cladding panel joints and podiums and floor movement joints, and what we’re called in for most is chipped joint edges on forklift routes and water dripping through deck or ramp joints. A single leaking joint is often how a building in Canning Town first comes to us: we look at the rest while we are there and tell you what we find.

Around Canning Town, 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.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

When to bring in a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Surface 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.

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.

Canning Town: questions and answers

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough

Can you take on a job at a hospital such as Newham University Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Are expansion joints and movement joints the same thing?

They’re closely related. Both let materials grow and shrink with temperature, moisture and load.

Joints that move: notes for Canning Town

At least three named trading, business or retail sites lie within about 3 miles of Canning Town. Their warehouses, yards and car parks are exactly where joints take the most punishment. London car parks, loading bays and podium decks often can’t close for long, so the work is broken into short sections agreed with the building manager.

In a school such as Rosetta Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Hospitals like Newham University Hospital (0.6 miles north-east of Canning Town) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Canning Town is about 5 miles east of London, in Greater London. Canning Town sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Greater London, 764 places are covered, Canning Town among them.

If your building is just outside Canning Town, we cover Custom House (1 mile south), Plaistow (1 mile north), Limmo Peninsula (1 mile west), West Silvertown (1 mile south) and Leamouth (1 mile west). Further afield, our area takes in London (5 miles west), City of Westminster (8 miles west), Marylebone (7 miles west), Kensington (10 miles west), St Pancras (6 miles west) and Shoreditch (5 miles west).

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. All of Greater London is in the ULEZ, and kerbside space in Canning Town can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand

Advice

Why act early in Canning Town

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind and repeated access costs add up. Where it helps, we quote both options. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why appoint us

  • Colour options checked against the specified product
  • A fixed quote before work starts
  • Commercial sealant work since 2005
  • One contact handling all your sites

Read our cost guide or how we’re accredited.

Maintenance after handover

A few simple habits keep the new joints working:

  • Reopen bays and walkways only after the stated cure time
  • Include every elevation and deck joint in periodic inspections
  • Check joints after long freezing spells
  • Keep stones and debris out of open joint lines

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.
