Expansion joint sealing in Shopwyke

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

Work for main contractors and building owners

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Expansion joint sealing in Shopwyke

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. We work on cladding panel joints, blockwork control joints and car park decks and ramps, and the usual reasons a site gets in touch are layers of sealant in a movement joint and brittle, chalky sealant on external joints. Most enquiries from Shopwyke 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.

Halls, schools and small commercial buildings near places like Shopwyke have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a building around Shopwyke, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements
  • Move anything stored against the joints

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Damaged metal nosings or cover plates over a joint
  • Movement on a scale no sealant is meant to absorb

If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in Shopwyke

  • Precast concrete panel joints
  • Blockwork control joints
  • Brickwork movement joints
  • Car park decks and ramps
  • Cladding panel joints
  • Podiums and floor movement joints

Common problems we fix in Shopwyke

When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.

Look out for the following:

  • Sealant peeling off one face of the joint
  • Rain penetration at brick or block movement joints
  • Arrises breaking up along floor joints
  • Weathered movement joint sealant that no longer flexes

A campus such as University of Chichester, 1.5 miles west of Shopwyke, has long runs of movement joint in its buildings, decks and paving.

Questions to ask before you appoint anyone

Shopwyke: questions and answers

Can you take on a job at a hospital such as St Richard's Hospital?

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

Does your area include sites such as Littlemeads Business Centre, near Shopwyke?

Yes. We cover Shopwyke and the area around it, including industrial estates, business parks and retail parks such as Littlemeads Business Centre. A few photographs 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.

Is Shopwyke in your area?

Yes. We cover Shopwyke. To discuss a job, speak to us on 01277 525 020 or email us.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

What happens if it rains on the day?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work so external dates keep some flexibility.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Floors, slabs and movement joints in Shopwyke

Rainfall across the South East, Shopwyke included, is lower than in many parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Shopwyke 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 St Richard's Hospital, 1.3 miles to the west of Shopwyke, depends on car parks, ramps and service yards whose joints take traffic all day. On a site such as Littlemeads Business Centre, which lies east of Shopwyke, the movement joints are in car park slabs, paving and building elevations.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Leave barriers in place until fresh joint sealant has cured
  • Report split or peeling joint sealant early
  • Include every elevation and deck joint in periodic inspections
  • Inspect exposed joints once the cold weather has passed

Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it. A routine sweep is the simplest protection.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
