Expansion joint sealing for Glenlochar sites

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

Aftercare for building managers

For the best life from the joints:

  • Keep stones and debris out of open joint lines
  • Act on the first tear or lifting edge rather than waiting
  • Check joints after long freezing spells
  • Keep product details with the building records for the next reseal

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can call the office on 01277 525 020 or email the details over and send a picture.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Expansion joint sealing in Glenlochar, done properly

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. Most enquiries involve spalled or broken joint edges in floors and decks and joints where the bead has lost adhesion, across cladding panel joints, precast concrete panel joints and podiums and floor movement joints. Most enquiries from Glenlochar start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Around smaller Scottish places like Glenlochar, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

From enquiry to sign-off

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. Then we strip out anything that has failed, prepare every joint and seal it. Travel to smaller Scottish places like Glenlochar is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. 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 flag anything that needs an engineer.
  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

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected

Expansion joint sealing in Glenlochar: the local picture

Glenlochar is in the east of Scotland, which is drier than the west. Freezing weather and salt still attack open external joints. Sealing them in drier months limits winter damage.

Schools like Castle Douglas High School often have long brick elevations with movement joints that age quietly. For an estate such as Castle Douglas Hospital, which lies south-east of Glenlochar, the joints in ramps, decks and long building elevations all need attention over time. If you manage units on an estate such as Abercromby Industrial Park (1.7 miles east of Glenlochar), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Glenlochar is about 17 miles south-west of Dumfries, in Dumfries and Galloway. Anywhere in DG7, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Glenlochar is one of 139 places we cover in Dumfries and Galloway for movement joints. Glasgow is covered too, some 63 miles away.

Questions we are asked in Glenlochar

Is Abercromby Industrial Park, near Glenlochar, within your area?

Yes, sites like Abercromby Industrial Park are within our area, along with the rest of Glenlochar. Photos and a short description are enough for a first look.

Can you take on a job at a hospital such as Castle Douglas Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

How much does the work cost?

Every job gets its own fixed quote. For yours, call 01277 525 020 or use the quote form with a description of the work.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Is movement joint sealing guaranteed?

The workmanship is guaranteed for 12 months from sign-off. Regular sweeping and inspection help the joints last.

Different surfaces, different methods

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first

Pricing movement joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • The postcode of the building
  • A wide shot and a close-up of the area
  • Approximate linear metres or a joint schedule
  • Your programme or deadline

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • 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)

If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.
