Expansion joint sealing for Cowlairs sites

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

How we handle expansion joint sealing in Cowlairs

We cover the full range of movement joints: 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. If you have new sealant over old, now failing and expansion joints split through the centre of the bead, we can put it right. Facilities teams, main contractors and managing agents in Cowlairs tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around the edges of Scotland’s cities are warehouses, trade counters and distribution units, each with saw-cut and construction joints under forklifts and pallet trucks. We work in phases with a product suited to the traffic, so operations carry on.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email us and we will arrange a return visit.

FAQs: Cowlairs

Is a hospital such as Stobhill Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

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

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

What’s the difference between an expansion joint and a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.

Why has the sealant in our expansion joints split?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing since each needs a different fix.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Give us the access times and building rules for your premises in Cowlairs, and we will plan the work to suit, phased where areas need to stay in use.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  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. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • Have the specification and drawings to hand
  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed

Advice

Slabs, ramps and loading bays in Cowlairs

The 3 miles around Cowlairs take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Cowlairs is in the west of Scotland, the wetter side of the country. External slab joints left open take plenty of rain. Outside joints are sealed in dry spells, so dates have some give.

Hospital campuses such as Stobhill Hospital, 1.1 miles north-east of Cowlairs, grow in stages, leaving movement joints wherever new blocks meet old. If you manage units on an estate such as Cowlairs Industrial Estate, under half a mile to the north-east of Cowlairs, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Campuses like Glasgow Caledonian University, 1.1 miles south of Cowlairs, mix old and new buildings, with movement joints wherever they meet.

Cowlairs is about 2 miles south-west of Bishopbriggs, in Glasgow. We send applicators to Cowlairs for movement joints. Cowlairs is one of 171 places we cover in Glasgow for movement joints.

We cover the G22, G21 and G4 postcode districts for movement joints. We cover commercial and managed buildings on Atlas Road, Walnut Road and Cowlairs Road. Being close to the A803 and A879, Cowlairs is easy to get to with materials and equipment. Close to Cowlairs, our area also takes in Possilpark (1 mile north-west), Parkhouse (1 mile north-west), Port Dundas (1 mile south-west), Hamiltonhill (1 mile west) and Sighthill (1 mile south). A short drive away, we cover Partickhill (3 miles west), Hyndland (3 miles west), Langside (4 miles south), Yoker (5 miles west), Partick (3 miles west) and Mount Florida (4 miles south).

Cost factors for movement joints

A fixed quote reflects the actual work. It takes account of:

  • Whether the work must be split into stages
  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email us with what you know.

Different surfaces, different methods

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.

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.

Keeping the joints sound

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

  • Record the sealant used and the date in the O&M file
  • Treat a small split as a warning, not a cosmetic issue
  • Keep scrapers and ploughs from dragging across joint sealant
  • Inspect movement joints alongside other routine building checks

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.

Why deal with it now?

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. Scottish city buildings take plenty of rain, and failed external joints let it into stone walls and around frames. Resealing promptly protects the stone and the interior.

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