About our expansion joint sealing in Auchendinny

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. Most enquiries involve debris jammed in movement joints and leaks through car park deck joints onto the level below, on precast concrete panel joints, car park decks and ramps and blockwork control joints. One point of contact handles commercial sealant work in Auchendinny from the first photos to the final walk-round, whether it’s one building or several.

Weather windows decide external joint work around a place like Auchendinny: dry faces and the right temperature are essential. Inside slabs aren’t affected and can be scheduled around the occupier.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Common questions from Auchendinny clients

Is a smaller place like Auchendinny outside your area?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.

Do you take on work at healthcare sites like Rosslynlee Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

What if the joint edges are damaged?

Sealant needs sound faces to bond to, so we’ll tell you if the edges need repairing before sealing. Where it’s visible beforehand, we’ll say so when we quote.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Looking after the joints

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

  • Act on the first tear or lifting edge rather than waiting
  • Keep racking legs and heavy point loads off floor joints
  • Keep scrapers and ploughs from dragging across joint sealant
  • Leave barriers in place until fresh joint sealant has cured

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Cost factors for movement joints

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

  • The size and state of each joint
  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • Access details, including height
  • Whether an asbestos survey exists

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or use the quote form.

Signs you need expansion joint sealing in Auchendinny

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.

Clients typically get in touch after noticing one or more of the following:

  • Leaks through car park deck joints onto the level below
  • Sealant pulling off the joint face
  • Expansion joints filled with dirt and stones
  • Expansion joints split through the centre of the bead

Retail centres such as Straiton Retail Park, 2.5 miles north of Auchendinny, have floors, service yards and car parks with joints under constant traffic.

What to look for in a quote

  • How they’ll work around occupants
  • Do they follow the manufacturer’s priming guidance?
  • Is the sealant right for the movement and the substrate?
  • Whether their applicators hold CSCS cards

Our contractor checklist

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Proprietary pre-formed expansion joint systems
  • A joint that has to be widened or re-detailed before it can work
  • Concrete or masonry repairs along the arrises

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly before you book.

Surfaces we seal

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

Building owners, agents and FMs in Auchendinny

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

How a job runs

Before any cutting starts, the area is protected: 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 we clear our waste as we work. Where we can, we combine work around Auchendinny with other jobs nearby. Tell us how flexible your dates are.

  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. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Share your working hours and any access restrictions
  • Let building users know which areas are affected
