Your questions answered
Is Roberton too small for you to travel to?
No. Places such as Roberton are covered as much as the big towns. We work across every Scottish council area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do we have to stop operations in Roberton while the joints are sealed?
Typically not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do the joint edges need to be sound before sealing?
Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member.
How we handle expansion joint sealing in Roberton
Joint design counts for as much as the sealant itself. 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, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on brickwork movement joints, blockwork control joints and cladding panel joints, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and damp inside where a wall movement joint has failed. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Roberton, preparation and product choice get the time they need.
In smaller places such as Roberton, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

More services for Roberton
Different surfaces, different methods
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Leaks coming from the membrane rather than the joint seal
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Movement on a scale no sealant is meant to absorb
If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

Keeping the joints sound
Once the work is signed off, these steps help:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Leave barriers in place until fresh joint sealant has cured
- Plan racking layouts so feet don’t land on a joint
- Act on the first tear or lifting edge rather than waiting
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.
Slabs, ramps and loading bays in Roberton
Being in the east of Scotland, Roberton gets less rain than the west coast. Cold winters and gritting are hard on any yard or deck joint left open. Sealing them in drier months limits winter damage.
In and around Roberton, the right filler or sealant for each joint depends on the traffic and the movement it takes. Once a joint near Roberton opens up, grit and water get in and the edges start to break.

What happens if it’s left?
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. Full removal and preparation is in every quote. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Roberton before they leak.
