Expansion joint sealing near Kingsfold

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

Expansion joint sealing in Kingsfold, done properly

The seal is what lets a movement joint do its job. 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. The enquiries we see most involve brittle, chalky sealant on external joints and leaks through car park deck joints onto the level below, on cladding panel joints, podiums and floor movement joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kingsfold it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Kingsfold, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Advice

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Kingsfold can sit alongside others in a wider programme across West Sussex.

What we’re called out for in Kingsfold

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.

It’s worth sending us details if you spot any of the following:

  • Layers of sealant in a movement joint
  • Brittle, chalky sealant on external joints
  • Movement joints with split or torn sealant
  • Expansion joints filled with dirt and stones

Business parks such as Northlands Business Park (1.7 miles west of Kingsfold) have car parks, paved areas and long brick and panel elevations, all with movement joints.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • How they’ll work around occupants
  • The terms of the workmanship guarantee
  • How the joint faces will be prepared and primed

Our contractor checklist

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Cracking or settlement that calls for an engineer’s assessment
  • Crumbling edges that would give a new bead nothing sound to grip

If you are not sure, just call 01277 525 020 or email drawings and photos and we will give you a straight answer.

Surfaces we seal

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

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Slabs, ramps and loading bays in Kingsfold

Rainfall across the South East, Kingsfold included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Kingsfold is about 28 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

Phasing is what makes joint work possible on busy sites such as North Heath Lane Industrial Estate (2.5 miles south of Kingsfold): one bay, aisle or car park row at a time. Hospitals like Horsham Hospital, 3.2 miles to the south of Kingsfold, have multi-storey or surface car parks whose joints carry vehicles round the clock.

What happens if it’s left?

A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. For buildings around smaller places like Kingsfold, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Pricing movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Questions we’re asked in Kingsfold

Can you take on a job at a hospital such as Horsham Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Can you work at a site such as Northlands Business Park, by Kingsfold?

Yes. Our area takes in Kingsfold and its surroundings, with estates and business parks such as Northlands Business Park included. To start, just give us a call on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Why has the sealant in our expansion joints split?

It depends on how the sealant has let go: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

How much does the work cost?

There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

Is colour matching possible?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
