How we handle expansion joint sealing in Knightswood

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. Every one calls for a sealant picked for its movement, exposure and traffic. If you have expansion joints split through the centre of the bead and previous reseals laid over old sealant, we can help. Facilities teams, main contractors and managing agents in Knightswood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In Scottish cities, where newer extensions meet older stone buildings, movement joints take the difference. They need the right movement class and correct width and depth to last.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Slabs, ramps and loading bays in Knightswood

Knightswood has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Knightswood is on Scotland’s wetter western side. External slab joints left open take plenty of rain. We wait for dry, workable days to seal them.

A campus such as University of Glasgow Garscube Campus, 1.2 miles to the north-east of Knightswood, has long runs of movement joint in its buildings, decks and paving. For an occupier at a site such as Anniesland Industrial Estate, 0.5 miles north-east of Knightswood, the joints at loading doors and dock levellers typically see the hardest wear. Sites like Gartnavel Royal Hospital (to the south-east of Knightswood) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Knightswood is about 2 miles south of Bearsden, in Glasgow. We cover Knightswood, with the same fixed quotes and 12-month guarantee as everywhere else. 171 places across Glasgow fall within our area, including Knightswood.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally 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. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Pass on the site’s contractor rules when you get in touch.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Advice

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Damaged metal nosings or cover plates over a joint
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Joints and surfaces we work on

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

Common questions from Knightswood clients

Will our site in Knightswood have to close for joint sealing?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Do you take on work at healthcare sites like Gartnavel Royal Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What if there’s asbestos in the old mastic?

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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you seal joints in cold or wet weather?

Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Different surfaces, different methods

Podium joints

Podium joints often sit within a waterproofing system. 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, typically low-modulus, with backing rod setting the depth.

Commercial clients in Knightswood

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

What sets the cost

These are the things that shape the price:

  • Access and working height
  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Working within restricted access windows

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Any specification or named product
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • The type of building and who uses it

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or send details through our quote form.

Why it’s worth doing now in Knightswood

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. We can split the scope into urgent and planned. In a Scottish city, access often needs scaffold, permits or factor approval, so deal with all failing joints while access is up.

Pricing movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
