How a job runs

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs near Rackwick are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Advice

Expansion joint sealing in Rackwick

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. If you are dealing with hardened, cracked sealant on exposed facades and damp inside where a wall movement joint has failed, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Rackwick it comes down to the same thing: the right product in a properly prepared joint.

Around smaller Scottish places like Rackwick, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Slabs and yards take vehicles, rain and frost.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Looking after the joints

A few simple habits keep the new joints working:

  • Avoid parking heavy plant or pallets on joint lines
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Leave barriers in place until fresh joint sealant has cured
  • Treat a small split as a warning, not a cosmetic issue

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We’ll tell you which movement joints need doing now and which can wait.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Where floor joints take the most wear near Rackwick

Rackwick sits close to the coast, within about 1 mile. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Rackwick is in the east of Scotland, which is drier than the west. Frost and winter road salt still work into open joints in car parks and yards. Resealing before the cold months helps protect the edges.

Around Rackwick, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Rackwick is about 24 miles north of Kirkwall, in the Orkney Islands. Businesses, contractors and managing agents in Rackwick use us for work on movement joints. 51 places across the Orkney Islands fall within our area, including Rackwick.

Postcode districts covered here: KW17 for movement joints. We also cover Pierowall (1 mile south), Brinian (14 miles south), Broughtown (14 miles east), Evie (16 miles south) and Lady (16 miles east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you phone 01277 525 020 or email us.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Changing the joint layout or spacing of a structure
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

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

What we are called out for in Rackwick

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way unless width and product are reviewed.

Look out for the following:

  • Expansion joints split through the centre of the bead
  • Damp inside where a wall movement joint has failed
  • Weathered movement joint sealant that no longer flexes
  • Layers of sealant in a movement joint

A joint near Rackwick that has lost its sealant lets in water and grit, and the edges suffer next.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Health and safety accreditation such as CHAS
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

Questions we are asked in Rackwick

Will you travel to Rackwick on the island?

Yes. We cover the whole of Scotland, and that includes island locations such as Rackwick. We group island work where we can and plan around the crossings.

Does the sea air around Rackwick change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

What causes movement joint sealant to fail?

The way it has failed usually tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Do you use silicone or polyurethane in movement joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane unless the specification names something else.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Leave it or put it right?

Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use, compared with a full closure. We agree phasing with you before work starts. Renewing every failing joint on one visit is the sensible approach for a place like Rackwick. Send photographs and we will quote for everything together.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
