Garlieston: questions and answers

Is Garlieston too far out for you?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can being near the sea in Garlieston affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Are expansion joints and movement joints the same thing?

Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably and the way they’re sealed is similar.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Expansion joint sealing for commercial buildings in Garlieston

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. Site teams most often ask us about hardened, cracked sealant on exposed facades and sealant peeling off one face of the joint, across brickwork movement joints, podiums and floor movement joints and precast concrete panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Garlieston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For outside joints near Garlieston, the Scottish weather sets the timetable: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Waterproofing layers buried beneath the sealant
  • Cracking or settlement that calls for an engineer’s assessment

If you’re not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

What we seal

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

Surface by surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.

Quoting for work in Garlieston

Before we quote, we look at:

  • The size and state of each joint
  • Any access equipment needed
  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants

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

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • The postcode of the building
  • Any dates the work must fit around

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and we clear our waste as we work. Where we can, we combine work around Garlieston with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Let building users know which areas are affected
  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings

Advice

Traffic, movement and joints around Garlieston

Garlieston lies within about 1 mile of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. The west of Scotland, where Garlieston is, gets more rain than the east. Open joints in external slabs take a lot of water. We wait for dry, workable days to seal them.

For floors and slabs around Garlieston, the product is chosen for the traffic and the movement at each joint.

Common problems we fix in Garlieston

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it.

What tends to prompt an enquiry:

  • Expansion joints filled with dirt and stones
  • Hardened, cracked sealant on exposed facades
  • Joints where the bead has lost adhesion
  • Torn sealant in brick or block movement joints

Around Garlieston, open joints collect water and debris, and the arrises are the next to go.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Who will actually carry out the work
  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

Leave it or put it right?

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex, so it fails quickly. We cut out the old seal and prepare the faces every time. Renewing every failing joint on one visit is the sensible approach for a place like Garlieston. Send photos and we will quote for everything together.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
