Expansion joint sealing for Baltasound sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Traffic, movement and joints around Baltasound

The sea is no more than about 2 miles from Baltasound. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. For an island location such as Baltasound, work is planned around ferry crossings and the weather. Send joint sizes and details of the traffic so the right materials come on the crossing.

Around Baltasound, each joint gets a filler or sealant matched to what crosses it and how much it moves. Schools such as Baltasound Junior High School have movement joints in their walls and floors that are easy to overlook.

Baltasound is in the Shetland Islands. Any commercial site in Baltasound is covered. We work across 63 places in the Shetland Islands.

We cover the ZE2 postcode districts. For a building on Setters Hill Estate, Curlew Avenue and Cormorant Way or nearby, send details and we’ll quote for movement joints. We also cover Haroldswick (3 miles north-east), Clivocast (6 miles south), Cullivoe (6 miles south-west), Houbie (11 miles south) and Camb (12 miles south-west) for movement joints. As one of the bigger centres in the Shetland Islands, Baltasound has a broad mix of commercial, public and industrial buildings, and we cover them all. Where a site is remote or on an island, we plan travel and materials carefully, so the full address helps from the start.

Nearby you will also find Unst Boat Haven (2.1 miles north-east). For a walk, there’s Loch of Beiton and Muckle Heog.

Expansion joint sealing for commercial buildings in Baltasound

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels. If the arrises are already broken, we will say so before sealing. We work on cladding panel joints, podiums and floor movement joints and car park decks and ramps, and the usual reasons a site gets in touch are water getting into the wall through a failed joint and joints where the bead has lost adhesion. Facilities teams, main contractors and managing agents in Baltasound tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

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

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

Why it’s worth doing now in Baltasound

Resealing is normally the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Baltasound before they leak.

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Why clients in Baltasound choose us

  • CHAS accredited
  • Fully insured
  • RAL and finish matching where the product range allows
  • Clear, fixed quotes

Read our cost guide and our accreditations and insurance.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Cracking or settlement that calls for an engineer’s assessment
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Where we work in Baltasound

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

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Baltasound can form part of a wider programme across the Shetland Islands.

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

What sets the cost

Before we quote, we look at:

  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • The size and state of each joint

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • Where the site is, with the postcode
  • Any dates the work must fit around
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back

For a fixed quote, speak to us on 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Tell us who will meet us and how to get in at your building near Baltasound. That goes into the plan alongside the quote.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry.
  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. We check every joint before sign-off, and the work carries our 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Let building users know which areas are affected
  • Share the asbestos register for older buildings

Your questions answered

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

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Can you take on a job in Baltasound, on the island?

Yes. We cover the whole of Scotland, and that includes island locations such as Baltasound. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load.

Can you work while the building is occupied?

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

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Do the joint edges need to be sound before sealing?

Broken arrises have to be put right before resealing, and we will point out where that’s the case. Sealing over them leads to early failure.

Which product is best for expansion joints?

The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Inspect exposed joints once the cold weather has passed
  • Treat a small split as a warning, not a cosmetic issue
  • Note which joints were done, when, and with what
  • Avoid parking heavy plant or pallets on joint lines

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.
