Why deal with it now?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Why us?

  • Commercial sealant work since 2005
  • Constructionline member for supplier checks
  • Matching to RAL references, product permitting
  • Work carried out by CSCS-carded applicators

Expansion joint sealing for commercial buildings in Pease Pottage

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. Site teams most often ask us about car park joints leaking onto vehicles below and movement joints with split or torn sealant, across cladding panel joints, car park decks and ramps and precast concrete panel joints. A single leaking joint is often how a building in Pease Pottage first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Small units near places like Pease Pottage are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

How the job changes by surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.

Common problems we fix in Pease Pottage

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.

What tends to prompt an enquiry:

  • Sealant pulling off the joint face
  • Movement joints with split or torn sealant
  • New sealant over old, now failing
  • Debris jammed in movement joints

Office parks like Tilgate Forest Business Centre (0.7 miles north of Pease Pottage) have decks, ramps and clad elevations whose joints take movement every day.

Questions to ask before you book

  • Their public liability cover
  • Their pre-qualification and accreditations
  • Which product they’ll use, and why it suits the joint
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

FAQs: Pease Pottage

Does your area include sites such as Tilgate Forest Business Centre, near Pease Pottage?

Yes. Estates, retail parks and business parks around Pease Pottage, Tilgate Forest Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Pease Pottage outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Do you guarantee expansion joint work?

Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Why do our movement joints keep failing?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing, because the fix differs.

Slabs, ramps and loading bays in Pease Pottage

At least three named trading, business or retail sites lie within about 3 miles of Pease Pottage. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Pease Pottage sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Phasing is what makes joint work possible on busy sites such as Holmbush Potteries Industrial Estate (2.1 miles north-west of Pease Pottage): one bay, aisle or car park row at a time. For a centre such as County Mall (2.1 miles north of Pease Pottage), the service yard and car park joints typically need attention first.
