How we handle expansion joint sealing in Scottish Borders

If you need expansion joint sealing in Scottish Borders, start with photos and joint lengths. We’ll come and look where photos don’t show enough. You can also give us a call on 01277 525 020 or email a schedule or drawings to talk the joints through. If you have hardened, cracked sealant on exposed facades and new sealant over old, now failing, we can put it right, whatever the surface. Whoever orders the work in Scottish Borders, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

In smaller places such as Scottish Borders, the joints we are asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Expansion joint sealing in Scottish Borders: the local picture

Scottish Borders is in the east of Scotland, which is drier than the west. Cold winters and gritting are hard on any yard or deck joint left open. Sealing them before winter limits the damage.

Around Scottish Borders, each joint gets a filler or sealant matched to what crosses it and how much it moves. A joint near Scottish Borders that has lost its sealant lets in water and grit, and the edges suffer next.

Scottish Borders is about 22 miles south-east of Carluke, in the Scottish Borders. We cover commercial sites throughout Scottish Borders, for single jobs and planned programmes alike. We work across 91 places in the Scottish Borders, from busy centres to rural villages. For work in that direction, see our Edinburgh page, about 31 miles away.

Postcode districts covered here: ML12. Access to Scottish Borders is via the A701 among other routes. Close to Scottish Borders, our area also takes in Broughton (7 miles north), Coulter (7 miles north-west), Biggar (8 miles north-west), Skirling (9 miles north) and Symington (9 miles north-west).

What’s near Scottish Borders

Cost factors for movement joints

A fixed quote reflects the actual work. It takes account of:

  • Joint width, depth and condition
  • How much existing material needs removing
  • Travel to remote or island sites
  • How much there is to seal

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • Specification clauses that apply
  • Clear photos of the problem areas
  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.

Leave it or put it right?

Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too and repeated access costs add up. We can price a patch and a full reseal side by side. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Scottish Borders before they leak.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why us?

  • Commercial sealant work since 2005
  • A fixed quote before work starts
  • RAL and finish matching where the product range allows
  • CSCS-carded applicators

Questions about Scottish Borders

Is Scottish Borders too far out for you?

Not at all. Scottish Borders is within our area. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

Which documents can you supply for work in Scottish Borders?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

What happens if it rains on the day?

Sealing onto a damp surface leads to adhesion failure. The work is simply moved to the next suitable day.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly.

Where we work in Scottish Borders

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

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Scottish Borders is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Flag any permit to work we will need
  • Tell us which areas need to stay in use
  • Send your site hours and access windows

Related advice

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Maintenance after handover

For the best life from the joints:

  • Note which joints were done, when, and with what
  • Clear dirt from joint lines during routine cleaning
  • Avoid parking heavy plant or pallets on joint lines
  • Brief car park operatives to protect joint lines during winter clearance

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.
