Glazing silicone in Sound
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. If you have water tracking down the inner face of the glass and cracked silicone between glass panels, we can help.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Whatever the size of the job, you get the same one-year guarantee.

What we’re called out for in Sound
Sealant laid over old sealant doesn’t last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
The problems people generally mention when they call are:
- Silicone pulling away from the glass
- Water tracking down the inner face of the glass
- Stained, discoloured glazing silicone
- Water getting into a conservatory at the joints
For site and facilities teams at buildings such as Anderson High School, larger buildings have plenty of frames, and the mastic around each one ages.

What glazing silicone looks like in Sound
Sound is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Sound, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
Sound is about 1 mile south-west of Lerwick, in the Shetland Islands. From the centre of Sound to the outskirts, glazing silicone is available for homes and businesses alike. 63 places in the Shetland Islands are on our list.
Work in ZE1 is quoted and booked the same way as anywhere else. We cover properties on Quoys Road, South Road and Oversund Road. If you’re just outside Sound, we cover Lerwick (1 mile north-east), Gulberwick (2 miles south-west), Gremista (2 miles north), Grindiscol (2 miles east) and Heogan (2 miles north-east). As one of the bigger places in the Shetland Islands, Sound has every kind of property, from flats to offices. For island and remote addresses, a little more planning is needed.
Around Sound
Around Sound, our work takes us to homes and buildings near Gilbertson Park and the streets around them. A little further out are Gilbert Bain Hospital (0.7 miles north-east) and Shetland Museum (1.2 miles north-east). For a walk, there’s Hill of Berry and Clickimin Loch.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from an hour or two to most of a day, depending on the size of the job. Around Sound, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Sound: your questions answered
Is glazing silicone in a coastal place like Sound any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Is Sound in your area for glazing silicone?
Yes, Sound is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How long does the job take?
As a guide, most jobs take a few hours, depending on how many joints need doing. Larger jobs naturally take longer, and we will say how long yours will take.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What sealant do you use on glazing?
We pick a glazing silicone to suit the materials. Neutral-cure silicone is the usual choice.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Act on drips or damp patches early
- Run a squeegee over the glass when you’re done
- Keep harsh solvents off the silicone
- Inspect the sealant on glazing annually
Avoid scraping near the new silicone when you clean. Stick to a soft cloth.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below long before you see it.
