Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
How we handle expansion joint sealing in Cornhill
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. The enquiries we see most involve expansion joints split through the centre of the bead and brittle, chalky sealant on external joints, across car park decks and ramps, podiums and floor movement joints and precast concrete panel joints. Searching for sealant specialists in Cornhill? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
In smaller places such as Cornhill, the joints we are asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What the job involves on each surface
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement, with primer where specified.
Floors, slabs and movement joints in Cornhill
Cornhill is in the east of Scotland, which is drier than the west. Cold winters and gritting are hard on any yard or deck joint left open. Autumn is a sensible time to seal them.

When to call us in Cornhill
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.
Clients typically get in touch after noticing one or more of the following:
- New sealant over old, now failing
- Sealant pulling off the joint face
- Joints packed with grit and debris
- Arrises breaking up along floor joints
For floors and slabs around Cornhill, the product is chosen for the traffic and the movement at each joint.

Questions about Cornhill
Is a hospital such as Campbell Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Cornhill too small for you to travel to?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Are expansion joints and movement joints the same thing?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing and both need a flexible seal.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
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. Broken edges are a third possibility.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. Tell us who will meet us and how to get in at your building near Cornhill. We’ll confirm the plan with the fixed quote.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Point out any areas we must not close
- Warn occupants and staff about the work
- Send any specification or drawings in advance
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Related advice
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Inspect exposed joints once the cold weather has passed
- Record the sealant used and the date in the O&M file
- Inspect movement joints alongside other routine building checks
- Raise snow-clearing blades over deck joints where possible
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
