Need expansion joint sealing in Walberton?

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

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Walberton are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Share your working hours and any access restrictions
  • Tell staff and tenants when we’ll be in

Expansion joint sealing in Walberton

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 comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you are dealing with movement joints with split or torn sealant and brittle, chalky sealant on external joints, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Walberton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Halls, schools and small commercial buildings near places like Walberton have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When something else is needed

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Movement on a scale no sealant is meant to absorb
  • Leaks coming from the membrane rather than the joint seal
  • Concrete or masonry repairs along the arrises

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Surfaces we seal

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

Building owners, agents and FMs in Walberton

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Do you need expansion joint sealing in Walberton?

When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way, so we check width and movement before quoting.

Most enquiries start with something like this:

  • Sealant pulling off the joint face
  • Torn sealant in brick or block movement joints
  • Water dripping through deck or ramp joints
  • Weathered movement joint sealant that no longer flexes

On industrial estates such as Tokar Industrial Park, 0.5 miles south-east of Walberton, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • Their pre-qualification and accreditations
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • The terms of the workmanship guarantee

Why act early in Walberton

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we’ll plan around it. Older rural buildings around Walberton move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why us?

  • Over 20 years of commercial sealing
  • One number for every site we cover
  • Matching to RAL references, product permitting
  • Health and safety: CHAS accredited

Is Walberton off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What guarantee do you give on joint sealing?

A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Expansion joint sealing in Walberton: the local picture

Walberton lies roughly 51 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.

Another example is Sussex Business Village (0.9 miles south of Walberton), where floors and yards would be done in stages around the occupiers. Campuses like University of Chichester (Bognor Campus) (4.3 miles south-west of Walberton) mix old and new buildings, with movement joints wherever they meet.

Walberton is about 5 miles north-west of Littlehampton, in West Sussex. Across the BN18 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Walberton is one of 373 places we cover in West Sussex for movement joints. Our Portsmouth page has more on work in that area (20 miles or so).

How the job changes by surface

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement.
