Expansion joint sealing in Amberley, done properly

The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on brickwork movement joints, blockwork control joints and car park decks and ramps, and what we are called in for most is expansion joints filled with dirt and stones and water getting into the wall through a failed joint. Most enquiries from Amberley start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Smaller community and commercial buildings around Amberley have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Common questions from Amberley clients

Will you take on work at estates like Quell Farm Industrial Estate, close to Amberley?

Yes, sites like Quell Farm Industrial Estate are within our area, along with the rest of Amberley. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Do you take on work at healthcare sites like Arundel and District Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you reseal car park expansion joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement with bays phased so the car park keeps operating.

Do you use silicone or polyurethane in movement joints?

The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane unless the specification names something else.

Are expansion joints and movement joints the same thing?

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.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Amberley can be grouped with others nearby. You will have a fixed quote before work starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Make sure the joints can be reached
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work

Advice

Joints that move: notes for Amberley

Amberley is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, while winter salting gets into any joint left open. Amberley lies roughly 45 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.

On industrial estates such as Quell Farm Industrial Estate, which lies north of Amberley, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Hospital campuses such as Arundel and District Hospital (to the south of Amberley) grow in stages, leaving movement joints wherever new blocks meet old.

Amberley is about 7 miles north of Littlehampton, in West Sussex. Looking for expansion joint sealing in Amberley? We can help. Our West Sussex coverage takes in 373 places. For work in that direction, see our Brighton page (18 miles or so).

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Clear dirt from joint lines during routine cleaning
  • Inspect exposed joints once the cold weather has passed
  • Keep product details with the building records for the next reseal
  • Avoid parking heavy plant or pallets on joint lines

Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.

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 can suggest an order, worst joints first.

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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

Quoting for work in Amberley

What shapes the price:

  • Any access equipment needed
  • How much existing material needs removing
  • The product specified
  • Travel to remote or island sites

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • The product your specification calls for
  • Clear photographs of the problem areas
  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send details through our quote form.

Do you need expansion joint sealing in Amberley?

When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.

These are often picked up first by site or facilities staff:

  • Rain penetration at brick or block movement joints
  • Joints where the bead has lost adhesion
  • Layers of sealant in a movement joint
  • Expansion joints split through the centre of the bead

Schools such as Amberley CofE Primary School have movement joints in their walls and floors that are easy to overlook.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • What site paperwork they can supply
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What level of public liability insurance do they hold?

What we can’t put right

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

  • Changing the joint layout or spacing of a structure
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Leaks coming from the membrane rather than the joint seal

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer before you book.
