Expansion joint sealing across Spitalfields

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Proprietary pre-formed expansion joint systems
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • A joint that has to be widened or re-detailed before it can work

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think before you book.

How we handle expansion joint sealing in Spitalfields

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it. The enquiries we see most involve movement joints with split or torn sealant and debris jammed in movement joints, across precast concrete panel joints, car park decks and ramps and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Spitalfields it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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.

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.

Your questions answered

Do you take on work at healthcare sites like Royal London Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

How much does the work cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or send photos by email with a description of the work.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Where floor joints take the most wear near Spitalfields

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. Spitalfields has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

A healthcare site such as Royal London Hospital (to the east of Spitalfields) depends on car parks, ramps and service yards whose joints take traffic all day. In a school such as Makers Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak. Another example is Anchor Retail Park, which lies east of Spitalfields, where floors and yards would be done in stages around the occupiers.

Spitalfields is about 1 mile north-east of London, in Greater London. We send applicators to Spitalfields for movement joints. Across Greater London, 764 places are covered, Spitalfields among them.

Postcode districts covered here: E1, EC2A and E1W. We cover commercial and managed buildings on New Road, Mark Lane and Bell Lane. Access to Spitalfields is via the A10 and A1202 among other routes, so getting applicators and materials to site is simple.

A short drive away, we cover City of Westminster (3 miles west), Marylebone (3 miles west), Kensington (6 miles west), Walthamstow (5 miles north-east), Hampstead (5 miles north-west) and Ruislip (15 miles west).

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. In Spitalfields, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

How the quote is worked out

We price every job individually. The main factors are:

  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers
  • Any access equipment needed
  • Joint width, depth and condition

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • When you need the work done
  • Specification clauses that apply

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or send details through our quote form.

What the job involves on each surface

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it.

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Look over external and deck joints after a hard winter
  • Record the sealant used and the date in the O&M file
  • Act on the first tear or lifting edge rather than waiting
  • Keep stones and debris out of open joint lines

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. Should you spot a problem, you can phone 01277 525 020 or email a schedule or drawings and send a picture.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

Why it’s worth doing now in Spitalfields

On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. We agree phasing with you before work starts. Failed sealant in a building in Spitalfields can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.

Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
