Expansion joint sealing across South Newington

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

How we handle expansion joint sealing in South Newington

Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. Most enquiries involve sealant peeling off one face of the joint and torn sealant in brick or block movement joints, across brickwork movement joints, cladding panel joints and podiums and floor movement joints. One point of contact handles commercial sealant work in South Newington from the first photographs to the final walk-round, whether it’s one building or several.

Jobs around smaller places like South Newington are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Why deal with it now?

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. Older rural buildings around South Newington move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why appoint us

  • Matching to RAL references, product permitting
  • Standard and matched colours in many product ranges
  • Commercial sealant work since 2005
  • 12-month guarantee on workmanship

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Cracking or settlement that calls for an engineer’s assessment
  • Leaks coming from the membrane rather than the joint seal

If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.

Joints and surfaces we work on

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

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and our waste is bagged and taken away as we go. Jobs in and around smaller places like South Newington are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Questions we’re asked in South Newington

Is a hospital such as Horton General Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do we have to stop operations in South Newington while the joints are sealed?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

What exactly is a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped and the way they’re sealed is similar.

What happens if it rains on the day?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

What will the job cost?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

How the job changes by surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement priming where the maker calls for it.

Floors, slabs and movement joints in South Newington

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. Central London is about 66 miles from South Newington. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

Hospitals like Horton General Hospital (to the north-east of South Newington) have multi-storey or surface car parks whose joints carry vehicles round the clock. In and around South Newington, the right filler or sealant for each joint depends on the traffic and the movement it takes.
