About our glazing silicone in Melby
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on glass-to-frame joints, glass balustrade bases and conservatory frames, and common reasons people get in touch are water escaping where a screen meets the wall and cracked silicone between glass panels.
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.
All of our work is guaranteed for twelve months, in Melby and everywhere else we cover.

What affects the quote in Melby
We do not publish a price list, because jobs vary so much. The quote depends on:
- When we can work, for business premises
- Mould in or behind the old joints
- The number and length of the joints
- Which sealant suits the joint
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
What to tell us for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- Roughly how big the job is
- Photos by email, if that is easy
- What’s wrong with the joints now

What the job involves on each surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. We reseal them with a sealant suited to the frame.

FAQs for Melby
Do you cover Melby for glazing silicone?
Yes, Melby is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Will you come out to Melby?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is balustrade sealant something you do?
Yes, we reseal the joint at the base channel. Fitting glass is a separate trade.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most jobs. Outside jobs in Melby 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 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.
- The glass and frame are cleaned and degreased.
- 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 sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
How to get a quote

Advice
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why act early in Melby
Topping up old silicone can look like a fix, but silicone does not stick to silicone and water soon finds its way back. Cutting out and resealing properly lasts. In a place like Melby, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Glazing silicone in Melby: local notes
Melby 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. 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.
Around Melby, as everywhere, glazing silicone is only as good as the preparation behind it. If you live in an older home near St Margaret's Kirk and Graveyard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Melby is in the Shetland Islands. Jobs in Melby get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 63 towns and villages across the Shetland Islands.
Our applicators cover all of ZE2 for glazing silicone and the streets around it. We also cover Sandness (1 mile south-east), Walls (6 miles south-east), Aith (10 miles east), Easter Skeld (11 miles south-east) and Brae (12 miles north-east). For island and remote addresses, a little more planning is needed.
