Expansion joint sealing for Galashiels sites

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

Expansion joint sealing for commercial buildings in Galashiels

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Galashiels. The enquiries we see most involve sealant peeling off one face of the joint and expansion joints split through the centre of the bead, on brickwork movement joints, precast concrete panel joints and podiums and floor movement joints. Most enquiries from Galashiels start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Schools, health centres and council buildings in towns like Galashiels have long runs of brick and panel movement joints. Resealing them before water gets in protects the wall behind.

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

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. Jobs in Galashiels are planned with two things in mind: the forecast for external joints and the building’s hours for internal ones. Send photos or drawings and we will quote and plan to suit.

  1. We assess the joints on site or from photographs, 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. 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. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints

Leave it or put it right?

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Water through a failed joint in a building in Galashiels can spoil ceilings, floors and stock. Early action limits what needs repairing.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

  • A Constructionline member, so easy to vet
  • Colour options checked against the specified product
  • Fully insured

Signs you need expansion joint sealing in Galashiels

Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.

If one of these sounds familiar, it’s time for a closer look:

  • Layers of sealant in a movement joint
  • Damp inside where a wall movement joint has failed
  • Car park joints leaking onto vehicles below
  • Brittle, chalky sealant on external joints

For an estate such as Borders General Hospital (2.7 miles south-east of Galashiels), the joints in ramps, decks and long building elevations all need attention over time.

How to choose a sealant contractor

Expansion joint sealing in Galashiels: the local picture

At least three named trading, business or retail sites lie within about 3 miles of Galashiels. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Galashiels is in the east of Scotland, which is drier than the west. Freezing weather and salt still attack open external joints. Sealing them before winter limits the damage.

A campus such as Heriot-Watt University - Scottish Borders Campus (0.9 miles south-east of Galashiels) has long runs of movement joint in its buildings, decks and paving. Schools such as Galashiels Academy have movement joints in their walls and floors that are easy to overlook.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • The product specified
  • Access and working height
  • Working within restricted access windows
  • Induction, permit and paperwork requirements

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

What we need to price the job

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
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send photos by email.

Work for main contractors and building owners

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.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Common questions from Galashiels clients

Must our site in Galashiels stop work while the joints are done?

Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

Can you work at a site such as Netherdale Industrial Estate, by Galashiels?

Yes. Estates, retail parks and business parks around Galashiels, Netherdale Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
