How we handle expansion joint sealing in Dunnet

Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. If you’re dealing with previous reseals laid over old sealant and water dripping through deck or ramp joints, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Dunnet tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Travel to smaller places like Dunnet is planned so the work is done in one trip where possible. Photos, approximate widths and what uses the floor help us bring the right materials.

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

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • The site’s rules and procedures
  • Phasing around occupants

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • Where the site is, with the postcode
  • What the building is and how it’s used

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Dunnet: questions and answers

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

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do we have to stop operations in Dunnet while the joints are sealed?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Is Dunnet in your area?

Yes. We cover Dunnet, within our coverage of Greater London, South East England and Scotland. To discuss a job, call 01277 525 020 or send details through our quote form.

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

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 sealing method is much the same.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact.

What do you charge?

Each job is quoted on its own details. For yours, call 01277 525 020 or email a schedule or drawings.

Signs you need expansion joint sealing in Dunnet

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.

Common reasons buildings call us in:

  • Spalled or broken joint edges in floors and decks
  • Weathered movement joint sealant that no longer flexes
  • Water dripping through deck or ramp joints
  • Joints where the bead has lost adhesion

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

What to look for in a quote

  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?
  • How joint depth will be controlled
  • How the joint faces will be prepared and primed

Expansion joint sealing around Dunnet: how the place shapes the job

Dunnet 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, so it pays to keep them sealed. Being in the east of Scotland, Dunnet gets less rain than the west coast. Freezing weather and salt still attack open external joints. Sealing them in drier months limits winter damage.

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

Dunnet is about 7 miles east of Thurso, in Highland. Businesses, contractors and managing agents in Dunnet use us for work on movement joints, as part of our coverage of Highland. Our Highland coverage takes in 256 places, from busy centres to rural villages.

We take on movement joints across the KW14 postcode area. If your building is just outside Dunnet, we cover Brough (2 miles north), Castletown (3 miles south-west), Scarfskerry (3 miles north-east), Rattar (3 miles north-east) and Murkle (4 miles south-west). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Keeping the joints sound

After handover, these steps help:

  • Leave barriers in place until fresh joint sealant has cured
  • Include every elevation and deck joint in periodic inspections
  • Brief car park operatives to protect joint lines during winter clearance
  • Note which joints were done, when, and with what

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint and we will tell you when each bay or area can reopen. Barriers left in place until then protect the finish.

An open joint fills with grit, and a joint full of grit can’t close. 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.

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Travel to smaller Scottish places like Dunnet is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
