Expansion joint sealing across South Leigh

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

Quoting for work in South Leigh

To price the job, we consider:

  • The product specified
  • Working within restricted access windows
  • The site’s rules and procedures
  • How accessible the joints are

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

Before you send an enquiry

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

  • The type of building and who uses it
  • Whether an asbestos survey exists
  • Access details, including height
  • Where the site is, with the postcode

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or send photos by email.

About our expansion joint sealing in South Leigh

We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you are dealing with brittle, chalky sealant on external joints and new sealant over old, now failing, we can help, whatever the surface. Looking for mastic applicators who cover South Leigh? We’ve been sealing commercial buildings since 2005.

Around smaller places such as South Leigh, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Commercial clients in South Leigh

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

What happens if it’s left?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we will tell you honestly. Converted and older buildings near places like South Leigh tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Why clients in South Leigh choose us

  • CSCS-carded applicators
  • Old sealant cut out, never sealed over
  • Fully insured
  • Health and safety: CHAS accredited

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:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

Joints and surfaces we work on

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

FAQs: South Leigh

Can you work at a site such as Horizon Technology Park, by South Leigh?

Yes. We cover South Leigh and the area around it, including industrial estates, business parks and retail parks such as Horizon Technology Park. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Can you take on a job at a hospital such as Witney Community Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How long does movement joint sealing take?

It usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, with phasing where areas must stay open. We will confirm when each area can be used again.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What if the joint edges are damaged?

Spalled edges need repairing before a new seal will last and we will flag every length affected. A bead on a broken edge soon lets go.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.

Our process

Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around South Leigh, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Tell us which areas need to stay in use
  • Make sure the joints can be reached
  • Point out parking and an unloading spot

Get a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email the details over.

What the job involves on each surface

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, normally low-modulus laid over backing rod at the correct depth.
