Mastic sealing near Scalloway
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
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.
Mastic sealing in Scalloway
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. We work on external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks, and what we are called in for most is damp patches beside frames and window mastic that has split and shrunk. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Scalloway is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Travel to smaller places like Scalloway is planned so several buildings can be done on one trip. Send addresses and photos for a quote covering the batch.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we are called out for in Scalloway
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
Things that typically lead to an enquiry:
- A mix of products and colours from past repairs
- Repeated reactive repairs to the same buildings
- Occupiers reporting cold air round windows
- Communal area joints that look neglected
Owners near Scalloway can renew frame and external mastic block by block on one programme.
Before you book anyone
- What site paperwork they can supply
- What the guarantee covers, and for how long
- Their approach to joint depth and backing
- Which product they’ll use, and why it suits the joint
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Scalloway, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Send your site hours and access windows
- Warn occupants and staff about the work

Related advice
Leave it or put it right?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Around smaller places like Scalloway, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Surface by surface
Commercial and mixed-use buildings
Commercial occupiers usually stay open during the work so the work is phased.
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.

Looking after buildings in and around Scalloway
The sea is no more than about 1 mile from Scalloway. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Scalloway is in the east of Scotland, which is drier than the west. Cold mornings still limit when outside mastic can go on. Block programmes are built with that in mind
If you are responsible for a building such as Methodist Church, frame and door mastic needs the same attention as any other property.

Scalloway: questions and answers
Our building in Scalloway is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
Can you take on a job in Scalloway, on the island?
Yes. Islands are part of our area, Scalloway included. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Keep a record of when each building was resealed
- Look at the sunniest and most exposed elevations first
- Keep bins and bikes away from communal door frames
- Share your contractor requirements early
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
