How we handle facade sealing in Sandwick
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you’re dealing with sealant pulling away from frames or panels and patch repairs that keep failing, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Sandwick is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Sandwick that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Facade sealing in Sandwick: the local picture
Sandwick is within about 1 mile of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Island jobs, Sandwick among them, are planned around the ferry and the forecast. With drawings and the programme in hand, the whole mastic package comes with us.
For contractors building in or near Sandwick, we seal to the drawings, the specification and the programme.
Sandwick is about 14 miles north of Lerwick, in the Shetland Islands. Businesses, contractors and managing agents in Sandwick use us for work on facade joints, as part of our coverage of the Shetland Islands. Sandwick is one of 63 places in the Shetland Islands on our list.

Just outside Sandwick, we also work in Clate (1 mile south), Symbister (1 mile north-east), Hamister (1 mile north), Huxter (1 mile east) and Tripwell (2 miles north-east).

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

On site: what to expect
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Jobs near Sandwick are often grouped with others in the same area. Let us know if your dates have any give.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Move anything stored against the joints
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000

General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Your questions answered
Does the sea air around Sandwick change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you work on the island where Sandwick is?
Yes. Islands are part of our area, Sandwick included. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Are you insured?
Yes. We’re fully insured, including public liability cover.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one.
Surface by surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint.
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.
Signs you need facade sealing in Sandwick
When the sealant tears down its centre, it has normally been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Clients normally get in touch after noticing something like this:
- Perimeter sealant that has split or peeled away
- Cladding panel joints that have opened up
- Unsightly perimeter sealant on a visible elevation
- Perimeter joints where frames meet the structure
Around Sandwick, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

- Will RAMS and insurance details be available?
- How joint depth will be controlled
- How long is the guarantee, and what does it include?
Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure. Renewing every failing joint on one visit is the sensible approach for a place like Sandwick. Send photos and we’ll quote for everything together.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
