The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours, depending on how many joints need doing. Outside jobs in Sandwick need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on

Glazing silicone in Sandwick
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for black or yellowed silicone on glass joints and drips on the inside of a conservatory window, on rooflights, glass-to-frame joints and conservatory frames.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job is covered by a one-year guarantee, wherever you are in the Shetland Islands.

Windows and doors in Sandwick
Sandwick is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Around Sandwick, as everywhere, glazing silicone is only as good as the preparation behind it.

What else we do in Sandwick
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How we quote for glazing silicone
Every job gets its own quote. This is what makes a difference:
- The size of the job
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
Combining jobs into one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.
What to tell us for a quote
When you contact us, it’s useful to know:
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
Do you need glazing silicone in Sandwick?
Glass and frames expand and contract with the temperature at different rates. In time, the sealant splits or pulls away.
Keep an eye out for any of the following:
- A quick top-up bead that didn’t last
- Water getting into a conservatory at the joints
- Leaks from the base of a shower screen
- Leaking glazing joints on a rooflight
Whether the job is in Sandwick itself or nearby, the right material for each joint matters as much as a neat finish.

Sandwick questions
Do you cover smaller places like Sandwick?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Sandwick for glazing silicone?
Yes. We work across all of Scotland, and Sandwick is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Will it make a mess?

Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Can you replace a misted double-glazed unit?
Glass replacement is not our trade. We reseal the joints around it and can tell you if a unit seems to have gone.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Clear the conservatory gutters regularly
- Avoid scraping close to the bead
- Avoid strong solvents on or near the sealant
- Ventilate the conservatory to cut condensation
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Housing providers, facilities teams and property managers book us too in Sandwick and across the Shetland Islands. We can quote a run of properties together, and we’re fully insured for the work.
Different surfaces, different methods
Conservatory frames
Frame joints face sun and rain all year. Renewed sealant keeps water out.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
