Expansion joint sealing for commercial buildings in Upton

Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Upton. We work on podiums and floor movement joints, blockwork control joints and precast concrete panel joints, and the usual reasons a site gets in touch are joints where the bead has lost adhesion and hardened, cracked sealant on exposed facades. Whoever orders the work in Upton, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What affects the price in Upton

The price varies from site to site. It mainly depends on:

  • How much existing material needs removing
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • A wide shot and a close-up of the area
  • Access details, including height
  • The asbestos register, for older buildings
  • Specification clauses that apply

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email drawings and photos.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Cracking or settlement that calls for an engineer’s assessment
  • Damaged metal nosings or cover plates over a joint
  • Concrete or masonry repairs along the arrises

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 before you book.

Surfaces we seal

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

How the job changes by surface

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

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, and we’ll confirm the colours available for the specified product.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. Planning a London job such as one in Upton starts with access. Send the building rules and access times with your enquiry.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open
  • Tell staff and tenants when we will be in

Expansion joint sealing around Upton: how the place shapes the job

At least three named trading, business or retail sites lie within about 3 miles of Upton. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time.

Retail centres such as Broadway Shopping Centre, 0.5 miles south-east of Upton, have floors, service yards and car parks with joints under constant traffic. For buildings at a park such as Old Bexley Business Park, which lies south-east of Upton, brick and panel movement joints are easy to forget until one leaks. Sites like Erith and District Hospital, 1.8 miles to the north-east of Upton, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

FAQs: Upton

Do you take on jobs in Upton where loading and access are tightly controlled?

Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it

Is Old Bexley Business Park, near Upton, within your area?

Yes. Our area takes in Upton and its surroundings, with estates and business parks such as Old Bexley Business Park included. A few photos and the unit address let us price the work.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Why do our movement joints keep failing?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

What exactly is a movement joint?

They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Inspect exposed joints once the cold weather has passed
  • Keep racking legs and heavy point loads off floor joints
  • Report split or peeling joint sealant early
  • Note which joints were done, when, and with what

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
