About our expansion joint sealing in Temple

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. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. We work on cladding panel joints, car park decks and ramps and blockwork control joints, and the failures we are asked to look at most are expansion joints filled with dirt and stones and sealant pulling off the joint face. Facilities teams, main contractors and managing agents in Temple tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around Temple, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. 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.

What happens if it’s left?

A torn seal left alone usually gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Aftercare for building managers

For the best life from the joints:

  • Note which joints were done, when, and with what
  • Plan racking layouts so feet don’t land on a joint
  • Brief car park operatives to protect joint lines during winter clearance
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. If anything looks wrong, give us a call on 01277 525 020 or email a schedule or drawings with photographs.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.

For managing agents and facilities managers

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

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Temple can sit alongside others in a wider programme.

Your questions answered

Can you cope with the access rules in a London building?

Yes. Inductions, permits and timed loading are routine for us in London. 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

Is hospital work, at somewhere like St Bartholomew's Hospital, something you do?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

How long will the joint resealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.

Can you seal joints in cold or wet weather?

Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Cost factors for movement joints

Quotes vary with the job. Expect it to depend on:

  • How much there is to seal
  • Distance, for remote addresses
  • Phasing around occupants
  • Whether old sealant has to be cut out first

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • The type of building and who uses it
  • The product your specification calls for
  • The asbestos register, for older buildings
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or send details through our quote form.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. 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.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. 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.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance

Advice

Where floor joints take the most wear near Temple

Temple 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. Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time.

A campus such as King's College London, less than half a mile west of Temple, has long runs of movement joint in its buildings, decks and paving. Across sites such as Southwark Bridge Business Centre, 0.9 miles south-east of Temple, floor and movement joints can be sealed in phases so units keep working. Retail centres such as Brunswick Centre (1 mile north-west of Temple) have floors, service yards and car parks with joints under constant traffic.

Temple is about 1 mile south of St Pancras, in City of London. We cover commercial sites throughout Temple, whether it’s a single job or part of a planned programme. Across City of London, 7 places are covered, including Temple.

Commercial sites across SE1, WC2H and WC2B are covered for movement joints. Among the streets we cover are Shoe Lane, Drury Lane and New Square, and sites on any of them can send details for a fixed quote. You’ll find Temple on or near the A4 and A40. We also cover Temple Bar (1 mile north), Blackfriars (1 mile east), Aldwych (1 mile west), Clare Market (1 mile north-west) and Covent Garden (1 mile west) for movement joints.

Local landmarks in Temple

Locally, jobs take us to sites close to Mercers' School, The Devereux pub and Garden Bridge. Nearby too are British Library of Political and Economic Science (under half a mile north-west), St Mary-at-Hill (1.2 miles east) and London Nautical School (under half a mile south).
