Expansion joint sealing for Shawhead sites

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

What happens if it’s left?

A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we will tell you honestly. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.

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 you will have a fixed figure to work with.

Expansion joint sealing for commercial buildings in Shawhead

Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. 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. We work on precast concrete panel joints, cladding panel joints and car park decks and ramps, and what we are called in for most is hardened, cracked sealant on exposed facades and new sealant over old, now failing. Whoever orders the work in Shawhead, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For outside joints near Shawhead, the Scottish weather sets the timetable: dry faces and the right temperature are essential, so dates have some give. Inside slabs aren’t affected and can be scheduled around the occupier.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

When it isn’t the sealant

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

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

What we seal

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

Shawhead: questions and answers

What site paperwork comes with a job in Shawhead?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is Shawhead too small for you to travel to?

No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.

Why do our movement joints keep failing?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing, rather than replacing like for like.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Which product is best for expansion joints?

The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote.

Can you work on car park ramps and decks?

Yes. Tell us how the car park is used and which areas must stay open.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Shawhead, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Agree which areas must stay open
  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs

Joints that move: notes for Shawhead

Being in the east of Scotland, Shawhead gets less rain than the west coast. Freezing weather and salt still attack open external joints. Resealing before the cold months helps protect the edges.

Around Shawhead, each joint gets a filler or sealant matched to what crosses it and how much it moves. Once a joint near Shawhead opens up, grit and water get in and the edges start to break.

Maintenance after handover

Once the work is signed off, these steps help:

  • Look over external and deck joints after a hard winter
  • Keep product details with the building records for the next reseal
  • Keep traffic off new joints until the cure time is up
  • Avoid parking heavy plant or pallets on joint lines

Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Resealing early limits the damage.

What sets the cost

We price every job individually. The main factors are:

  • Removal of failed or old sealant
  • Travel to remote or island sites
  • The total length or number of joints
  • How accessible the joints are

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

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

  • Whether the building will be occupied during the work
  • The product your specification calls for
  • When you need the work done
  • Photos of the joints, close up and from further back

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or phone 01277 525 020 or send photos by email to discuss it first.

Different surfaces, different methods

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.
