Expansion joint sealing for Sutton sites

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

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Building owners and managing agents use us on everything from one building to a spread of sites around Sutton. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Expansion joint sealing for commercial buildings in Sutton

Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. Most enquiries involve brittle, chalky sealant on external joints and torn sealant in brick or block movement joints, on brickwork movement joints, car park decks and ramps and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sutton it comes down to the same thing: the right product in a properly prepared joint.

Smaller community and commercial buildings around Sutton have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Why deal with it now?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. We cut out the old seal and prepare the faces every time. For buildings around smaller places like Sutton, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For work around Sutton, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Flag any permit to work we will need
  • Tell staff and tenants when we will be in

What the job involves on each surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Common questions from Sutton clients

Do you take on work at healthcare sites like Arundel and District Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Must our site in Sutton stop work while the joints are done?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

What if the joint edges are damaged?

Sound edges are essential. If they’re damaged, we’ll say so before any sealing, so the new seal has something to grip.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Do you use silicone or polyurethane in movement joints?

Whatever suits the joint and the specification. The quote states the sealant and its movement class so there are no surprises.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Will your applicators have CSCS cards?

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

Honest limits

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

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Concrete or masonry repairs along the arrises
  • Changing the joint layout or spacing of a structure

If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Surfaces we seal

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

Expansion joint sealing in Sutton: the local picture

Central London is about 46 miles from Sutton. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

In and around Sutton, the right filler or sealant for each joint depends on the traffic and the movement it takes. Hospital campuses such as Arundel and District Hospital (5.3 miles south-east of Sutton) grow in stages, leaving movement joints wherever new blocks meet old.

Sutton is about 9 miles north-west of Littlehampton, in West Sussex. If you are looking for expansion joint sealing in Sutton, we can help, as we do across West Sussex. Our West Sussex coverage takes in 373 places. Sites around Portsmouth have their own page, roughly 22 miles from Sutton.

Should maintenance staff do it?

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
