Expansion joint sealing in Plumpton Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Common problems we fix in Plumpton Green

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.

Things that typically lead to an enquiry:

  • Arrises breaking up along floor joints
  • Joints packed with grit and debris
  • Water dripping through deck or ramp joints
  • Previous reseals laid over old sealant

For a school such as Plumpton Primary School, playground and building joints can be done in the holidays.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • Who will actually carry out the work
  • Whether old or failed sealant will be cut out, not overlaid
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Expansion joint sealing in Plumpton Green, done properly

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you are dealing with damp inside where a wall movement joint has failed and car park joints leaking onto vehicles below, we can put it right, whatever the surface. Whoever orders the work in Plumpton Green, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Jobs around smaller places like Plumpton Green are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Questions about Plumpton Green

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

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you take on work at estates like Park Farm Business Park, close to Plumpton Green?

Yes. We cover Plumpton Green and the area around it, including industrial estates, business parks and retail parks such as Park Farm Business Park. 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.

What guarantee do you give on joint sealing?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

What’s the difference between an expansion joint and a movement joint?

They’re closely related. Both let materials grow and shrink with temperature, moisture and load while the sealant stops grit and water getting in.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

How the job changes by surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Podium joints

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

Why it’s worth doing now in Plumpton Green

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. We can split the scope into urgent and planned. Converted and older buildings near places like Plumpton Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

A quote for movement joints depends on how many there are, their condition and the access. Call for a quote.

What you get with us

  • Work carried out by CSCS-carded applicators
  • Colours chosen to suit frames, cladding or finishes where possible
  • Work to your specification and the manufacturer’s guidance
  • A range of standard colours, depending on the product

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Waterproofing layers buried beneath the sealant
  • Movement on a scale no sealant is meant to absorb
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If you are not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

What we seal

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

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
