Need expansion joint sealing in Alfold Crossways?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

On site: what to expect

The first thing on site is a walk round with your contact, 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. If others near Alfold Crossways need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  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. 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.

What we need from you

  • Tell us which areas need to stay in use
  • Move anything stored against the joints
  • Share the asbestos register for older buildings

Expansion joint sealing for commercial buildings in Alfold Crossways

A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve movement joints with split or torn sealant and joints where the bead has lost adhesion, across brickwork movement joints, car park decks and ramps and podiums and floor movement joints. Whoever orders the work in Alfold Crossways, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a site near Alfold Crossways, measurements and photos up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions we are asked in Alfold Crossways

Is Alfold Crossways too far out for you?

Not at all. Alfold Crossways is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will our site in Alfold Crossways have to close for joint sealing?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How long does movement joint sealing take?

Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote, including any phasing.

What will the job cost?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

After the work

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Plan racking layouts so feet don’t land on a joint
  • Reopen bays and walkways only after the stated cure time
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Report split or peeling joint sealant early

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines.

On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.

Common problems we fix in Alfold Crossways

Sealant peeling cleanly off one side is an adhesion failure. 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:

  • Hardened, cracked sealant on exposed facades
  • Movement joints with split or torn sealant
  • Arrises breaking up along floor joints
  • Layers of sealant in a movement joint

On industrial estates such as Littlemead Industrial Estate (2.6 miles north of Alfold Crossways), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

What to look for in a quote

  • Their pre-qualification and accreditations
  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • Will failed sealant be removed rather than covered?

Slabs, ramps and loading bays in Alfold Crossways

At about 33 miles from central London, Alfold Crossways is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Alfold Crossways sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Across sites such as The Old Brickworks Industrial Estate, 2.8 miles east of Alfold Crossways, floor and movement joints can be sealed in phases so units keep working.

Alfold Crossways is about 9 miles west of Horsham, in Surrey. We cover commercial sites throughout Alfold Crossways. Alfold Crossways is one of 379 places in Surrey on our list. Brighton is covered too, some 25 miles away.

Different surfaces, different methods

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.

Why it’s worth doing now in Alfold Crossways

Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use. We agree phasing with you before work starts. Halls, stores and units around places like Alfold Crossways may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

See what affects the cost or how we’re accredited.

What sets the cost

Each job is priced on its own details. The main factors are:

  • The site’s rules and procedures
  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Removal of failed or old sealant

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

We can often quote from photos and a few details. It helps to include:

  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • When you need the work done

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
