Expansion joint sealing for Upton sites

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

Expansion joint sealing in Upton, done properly

If you need expansion joint sealing in Upton, start with photographs and joint lengths. We’ll come and look where photographs don’t show enough, then send a fixed quote that names the sealant. You can also give us a call on 01277 525 020 or email a schedule or drawings to talk the joints through. Most enquiries involve damp inside where a wall movement joint has failed and car park joints leaking onto vehicles below, on car park decks and ramps, cladding panel joints and brickwork movement joints. Most enquiries from Upton start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around Upton, most floor and movement joint jobs are single buildings or yards. That way the right materials come on the day and the job is done in one visit where possible.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Commercial clients in Upton

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

What we are called out for in Upton

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’s common on joints sealed in a hurry.

These are often picked up first by site or facilities staff:

  • Previous reseals laid over old sealant
  • Water getting into the wall through a failed joint
  • Arrises breaking up along floor joints
  • Joints where the bead has lost adhesion

On industrial estates such as Pysons Road Industrial Estate (0.6 miles west of Upton), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Our contractor checklist

Common questions from Upton clients

Can you work on a hospital site such as Queen Elizabeth The Queen Mother Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Does a coastal location like Upton affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Do the joint edges need to be sound before sealing?

Broken arrises have to be put right before resealing, and we will point out where that’s the case. Sealing over them leads to early failure.

What the job involves on each surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Why deal with it now?

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open without shutting the whole car park. We agree phasing with you before work starts. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. What matters most for a job in Upton is a clear list of what needs doing. A fixed quote follows.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

Quotes

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email drawings and photos with what you know.

Joints that move: notes for Upton

Upton is within about 1 mile of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster.

In a school such as Upton Junior School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
