How we handle expansion joint sealing in St Boswells
Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. If you have arrises breaking up along floor joints and brittle, chalky sealant on external joints, we can put it right, whatever the surface. Whoever orders the work in St Boswells, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Weather windows decide external joint work around a place like St Boswells: dry faces and the right temperature are essential, so dates have some give. Inside slabs aren’t affected and can be scheduled around the occupier.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

St Boswells: questions and answers
Would you work within a site like Dingleton Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like St Boswells outside your area?
No. Places such as St Boswells are covered as much as the big towns. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
What exactly is a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably, and the sealing method is much the same.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Common problems we fix in St Boswells
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.
It’s worth sending us details if you spot any of the following:
- Torn sealant in brick or block movement joints
- Sealant peeling off one face of the joint
- Chipped joint edges on forklift routes
- New sealant over old, now failing
For an estate such as Dingleton Hospital (3.7 miles west of St Boswells), the joints in ramps, decks and long building elevations all need attention over time.

Being in the east of Scotland, St Boswells gets less rain than the west coast. Freezing weather and salt still attack open external joints. Sealing them in drier months limits winter damage.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Movement on a scale no sealant is meant to absorb
- 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)
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly.

After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Leave barriers in place until fresh joint sealant has cured
- Keep stones and debris out of open joint lines
- Include every elevation and deck joint in periodic inspections
- Raise snow-clearing blades over deck joints where possible
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.
What sets the cost
Before we quote, we look at:
- How much there is to seal
- Backing rod, priming and other preparation
- Distance, for remote addresses
- Removal of failed or old sealant
A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

- Any dates the work must fit around
