Expansion joint sealing for Strathy sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Surface by surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

How we handle expansion joint sealing in Strathy

We have been sealing expansion and movement joints for over 20 years. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on brickwork movement joints, cladding panel joints and precast concrete panel joints, and what we are called in for most is expansion joints split through the centre of the bead and layers of sealant in a movement joint. Whoever orders the work in Strathy, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In smaller places such as Strathy, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Slabs and yards take vehicles, rain and frost.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Signs you need expansion joint sealing in Strathy

Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.

Typical triggers for a call:

  • Spalled or broken joint edges in floors and decks
  • Joints where the bead has lost adhesion
  • Car park joints leaking onto vehicles below
  • Damp inside where a wall movement joint has failed

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

What to look for in a quote

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants
  • Health and safety accreditation such as CHAS
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

Expansion joint sealing around Strathy: points for this area

The sea is no more than about 1 mile from Strathy. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. The west of Scotland, where Strathy is, gets more rain than the east. Rainwater through open yard and deck joints is a bigger issue here than in the drier east. External sealing is booked for dry spells, with some give in the dates.

Once a joint near Strathy opens up, grit and water get in and the edges start to break; we’ll tell you if the edges need repairing first.

Strathy is about 17 miles west of Thurso, in Highland. We send applicators to Strathy for movement joints, handled exactly as we handle every other area. Our Highland coverage takes in 256 places.

Quoting for work in Strathy

To price the job, we consider:

  • The size and state of each joint
  • The product specified
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites

Pricing movement joints depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

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

  • Whether the building will be occupied during the work
  • Any dates the work must fit around
  • Asbestos survey details if the building is older
  • Any specification or named product

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Strathy, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  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.

Before we start on site

  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Waterproofing layers buried beneath the sealant
  • Concrete or masonry repairs along the arrises
  • Joints too narrow for the movement, which need redesigning by the engineer

If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Surfaces we seal

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

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

FAQs: Strathy

Does a site in Strathy have to shut while its joints are sealed?

Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.

Our building in Strathy is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

How long does movement joint sealing take?

Expect a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, with phasing where areas must stay open. Cure time before reopening is confirmed on the day.

Do you cover Strathy?

Yes. Sites across Strathy are covered, with one number for every area we cover.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Can you seal joints in cold or wet weather?

Outside work depends on conditions. Indoor joints can normally carry on regardless.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.
