Expansion joint sealing in Elephant and Castle

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

Signs you need expansion joint sealing in Elephant and Castle

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.

Most enquiries start with something like this:

  • New sealant over old, now failing
  • Sealant peeling off one face of the joint
  • Torn sealant in brick or block movement joints
  • Hardened, cracked sealant on exposed facades

Another example is Southwark Bridge Business Centre (0.6 miles north-east of Elephant and Castle), where floors and yards would be done in stages around the occupiers.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • Their public liability cover
  • Whether old or failed sealant will be cut out, not overlaid
  • Do they follow the manufacturer’s priming guidance?

About our expansion joint sealing in Elephant and Castle

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Elephant and Castle. We work on brickwork movement joints, cladding panel joints and precast concrete panel joints, and the failures we are asked to look at most are joints packed with grit and debris and expansion joints split through the centre of the bead. Most enquiries from Elephant and Castle start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

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 are upfront about that.

Common questions from Elephant and Castle clients

Do you take on jobs in Elephant and Castle where loading and access are tightly controlled?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Does your area include sites such as Grand Vitesse Industrial Estate, near Elephant and Castle?

Yes. We cover Elephant and Castle and the area around it, including industrial estates, business parks and retail parks such as Grand Vitesse Industrial Estate. A few photos and the unit address let us price the work.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use.

What’s the difference between an expansion joint and a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint and both need a flexible seal.

Do you reseal car park expansion joints?

Yes. We use a sealant designed for wheel loads and the expected movement.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Elephant and Castle. One quote can cover more than one site, which keeps the paperwork simple.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs

Related advice

Different surfaces, different methods

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.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

Leave it or put it right?

Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we will plan around it. Getting scaffold, permits or access booked in Elephant and Castle takes effort, so it makes sense to deal with every failing joint while access is in place.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
