How the job changes by surface
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. They’re resealed with a suitable sealant.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
About our glazing silicone in Sandness
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you’re dealing with glazing silicone that has cracked or come away and water getting into a conservatory at the joints, we can put it right.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Whatever the size of the job, you get the same 12-month guarantee.

Windows and doors in Sandness
Sandness is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
In the older streets around St Margaret's Kirk and Graveyard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Sandness is in the Shetland Islands. Homes, rented property, offices and hotels in Sandness is covered for glazing silicone, old or new, large or small. Every job comes with our one-year guarantee. We cover 63 towns and villages across the Shetland Islands, from the larger towns to small villages.
All of ZE2 is covered for glazing silicone. If you’re just outside Sandness, we cover Melby (1 mile north-west), Walls (6 miles south-east), Aith (10 miles east), Easter Skeld (11 miles south-east) and Brae (12 miles north-east). If you are somewhere remote, a little more planning is needed.

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most jobs, depending on how much there is to do. Around Sandness, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We find where water is getting in and check whether it’s a sealant joint.
- 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 check the joints and, where safe, run water over them.
Before we arrive
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

What affects the cost of glazing silicone
There’s no set price list, because no two jobs are the same. What we look at:
- The product the joint needs
- Any working-time requirements on site
- Whether the work is at height
- Whether old sealant or filler has to be cut out
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- The type of property
- Any previous sealing or DIY work
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Do you need glazing silicone in Sandness?
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Keep an eye out for these signs:
- Glazing silicone that has cracked or come away
- Drips on the inside of a conservatory window
- Shower screens leaking along the wall or tray
- Failed joints on frameless glass
In and around Sandness, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

Should I try DIY first?

Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
When something else is needed
It helps to know what we cannot do:
- Failed flashing around a conservatory
- Structural problems with a conservatory roof
- A sealed unit that has misted inside
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Rooflights
- Glass balustrade bases
- Shower screens
- Glass-to-frame joints
- Conservatory frames
- Glass-to-glass joints
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Stick to mild cleaners on glass
- Don’t leave a drip for the next storm
- Use gentle products around the joints
- Keep conservatory gutters clear of leaves
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
