About our expansion joint sealing in Bakers Arms

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 while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on brickwork movement joints, blockwork control joints and car park decks and ramps, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and arrises breaking up along floor joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bakers Arms it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Areas such as a loading bay or car park deck in Bakers Arms typically have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Work for main contractors and building owners

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

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. On site, the work usually 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, and our waste is bagged and taken away as we go. In Bakers Arms, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Point out any areas we must not close
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Keeping the joints sound

To get the most from the new sealant:

  • Leave barriers in place until fresh joint sealant has cured
  • Look over external and deck joints after a hard winter
  • Record the sealant used and the date in the O&M file
  • Include every elevation and deck joint in periodic inspections

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Concrete or masonry repairs along the arrises
  • Cracking or settlement that calls for an engineer’s assessment
  • Joints too narrow for the movement, which need redesigning by the engineer

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

FAQs: Bakers Arms

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough

Would you work within a site like Whipps Cross University Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Why has the sealant in our expansion joints split?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How do we ask for a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.

Traffic, movement and joints around Bakers Arms

At least three named trading, business or retail sites lie within about 3 miles of Bakers Arms. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. 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.

For a centre such as Leyton Mills Retail Park, which lies south of Bakers Arms, the service yard and car park joints normally need attention first. Hospital campuses such as Whipps Cross University Hospital (0.7 miles east of Bakers Arms) grow in stages, leaving movement joints wherever new blocks meet old.

Common problems we fix in Bakers Arms

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.

Site and facilities staff are often the first to spot these:

  • Expansion joints split through the centre of the bead
  • Damp inside where a wall movement joint has failed
  • Sealant peeling off one face of the joint
  • Leaks through car park deck joints onto the level below

Phasing is what makes joint work possible on busy sites such as Ravenswood Industrial Estate (0.6 miles north of Bakers Arms): one bay, aisle or car park row at a time.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • Are they CHAS accredited or on Constructionline?
  • Will CSCS-carded applicators be on site?
  • Can the work be phased to keep areas open?

Our contractor checklist

Surface by surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

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, with a flexible sealant where movement is larger.
