How we handle facade sealing in Inverarnan
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Inverarnan. Coping and flashing joints are included where sealant is the specified fix. The enquiries we see most involve perimeter sealant that has split or peeled away and discoloured or dirty facade joints, on shopfront frames, stone and brick facade joints and perimeter joints where frames meet the structure. Facilities teams, main contractors and managing agents in Inverarnan tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Inverarnan that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Different surfaces, different methods
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed.
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.
Building owners, agents and FMs in Inverarnan
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Where we can, we combine work around Inverarnan with other jobs nearby. Tell us how flexible your dates are.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Before we start on site
- Explain the parking and delivery arrangements
- Move anything stored against the joints
- Point out any areas we must not close

Advice
Leave it or put it right?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, so the real damage is often some distance away. For buildings near Inverarnan, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

When to call us in Inverarnan
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
These are often picked up first by site or facilities staff:
- Air leaks through failed facade joints
- Cladding panel joints that have opened up
- Unsightly perimeter sealant on a visible elevation
- Sealant pulling away from frames or panels
Window perimeters and facade joints around Inverarnan need correct width, depth and backing rod as much as a neat finish.

Inverarnan: questions and answers
Is a smaller place like Inverarnan outside your area?
Not at all. Inverarnan is within our area. 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.
Can you work to our programme on a site in or near Inverarnan?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you offer coloured sealant?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Replacing glass or failed glazing units
- Damaged frames that need replacing
- Movement beyond what any sealant can handle
If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think before you book.
