Expansion joint sealing in Newton Stewart

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability 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. We work on brickwork movement joints, precast concrete panel joints and cladding panel joints, and what we’re called in for most is previous reseals laid over old sealant and sealant pulling off the joint face. A single leaking joint is often how a building in Newton Stewart first comes to us: we look at the rest while we are there and tell you what we find.

Weather windows decide external joint work around a place like Newton Stewart: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Surface by surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability.

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Travel to smaller Scottish places like Newton Stewart is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Flag any permit to work we will need
  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work

Questions we are asked in Newton Stewart

Is a smaller place like Newton Stewart outside your area?

No. Places such as Newton Stewart are covered as much as the big towns. We cover the whole of Scotland. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is hospital work, at somewhere like Newton Stuart Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is any job too small?

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

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

What do you charge?

There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.

What timescale should we allow for resealing expansion joints?

It normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We confirm the timescale with the quote along with the phasing plan.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Look over external and deck joints after a hard winter
  • Keep scrapers and ploughs from dragging across joint sealant
  • Report split or peeling joint sealant early
  • Put movement joints on the planned maintenance inspection round

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.

Why deal with it now?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Newton Stewart before they leak.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we are called out for in Newton Stewart

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way.

These are often picked up first by site or facilities staff:

  • Hardened, cracked sealant on exposed facades
  • Water getting into the wall through a failed joint
  • Expansion joints filled with dirt and stones
  • Spalled or broken joint edges in floors and decks

For a school such as Douglas Ewart High School, playground and building joints can be done in the holidays.
