Expansion joint sealing for commercial buildings in Dunollie
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors on sites in Dunollie. We work on precast concrete panel joints, blockwork control joints and cladding panel joints, and the failures we are asked to look at most are expansion joints split through the centre of the bead and car park joints leaking onto vehicles below. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dunollie is the same: the right product in a properly prepared joint.
Around smaller Scottish places like Dunollie, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Common questions from Dunollie clients
Do you take on work at healthcare sites like Lorn and Islands Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Our building in Dunollie is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
What causes movement joint sealant to fail?
The way it has failed typically tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.
What happens if old sealant might contain asbestos?
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 if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
What exactly is a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing.
How long does movement joint sealing take?
Allow 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.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Around smaller places like Dunollie, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Different surfaces, different methods
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
When to call us in Dunollie
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens.
Most enquiries start with one or more of the following:
- Sealant peeling off one face of the joint
- Expansion joints split through the centre of the bead
- Water dripping through deck or ramp joints
- Expansion joints filled with dirt and stones
Schools like Oban High School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- Will CSCS-carded applicators be on site?
- The terms of the workmanship guarantee
- How they’ll work around occupants
- Their pre-qualification and accreditations
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building near Dunollie, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Point out parking and an unloading spot
- Tell staff and tenants when we will be in
- Have the specification and drawings to hand

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Inspect exposed joints once the cold weather has passed
- Brief car park operatives to protect joint lines during winter clearance
- Keep product details with the building records for the next reseal
- Inspect movement joints alongside other routine building checks
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.

How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we look at:
- Induction, permit and paperwork requirements
- The size and state of each joint
- Access and working height
- Removal of failed or old sealant
There’s no price list, since every building and every scope is different. Call for a quote.
Sending details for a quote
To price the job accurately, we need to understand the site. Send us:
- Access details, including height
- Where the site is, with the postcode
- When you need the work done
- Whether an asbestos survey exists
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Slabs, ramps and loading bays in Dunollie
Dunollie lies within about 1 mile of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. The west of Scotland, where Dunollie is, gets more rain than the east. Open joints in car parks and yards let in more water than in drier areas. We wait for dry, workable days to seal them.
For an estate such as Lorn and Islands Hospital, 1.4 miles to the south of Dunollie, the joints in ramps, decks and long building elevations all need attention over time.
