Glazing silicone in Prestonfield
Glass replacement is not something we do and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that is often where the water gets in. If you are dealing with water tracking down the inner face of the glass and new silicone smeared over old sealant, we can put it right.
Prestonfield is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, which usually means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
You get a 12-month guarantee, the same in Prestonfield as everywhere else we work.

FAQs for Prestonfield
How is work on the outside of a tenement in Prestonfield generally arranged?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.
Does living near the coast affect glazing silicone in Prestonfield?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long does glazing silicone take?
That depends on the amount of work, but most jobs take a few hours for most jobs. We’ll give you a better idea when we quote.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you fit new glass or sealed units?
No. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Surface by surface
Glass balustrade bases
The base joint is cut out and resealed. Glass fitting is a separate trade.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
Glazing silicone in Prestonfield: local notes
Prestonfield 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. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Windows normally belong to the flat, but the title deeds have the final say.
If you live in an older home near Priestfield Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as St Margaret's School, larger buildings have plenty of frames, and the mastic around each one ages.

Aftercare tips
After the cure time, these simple habits help:
- Get a new leak looked at quickly
- Stick to mild cleaners on glass
- Clear the conservatory gutters regularly
- Inspect the sealant on glazing annually
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we’ll find out which.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Water coming through the roof rather than a sealant joint
- Rotten or badly damaged frames
- Condensation trapped between two panes
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Surfaces we seal
- Glass balustrade bases
- Conservatory frames
- Shower screens
- Glass-to-glass joints
- Glass-to-frame joints
- Rooflights
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
When to call us in Prestonfield
Glass and frames expand and contract with the temperature at different rates. In time, the sealant splits or pulls away.
The problems people usually mention when they call include:
- Glazing silicone that has cracked or come away
- Glass-to-glass joints that have split
- Sealant that was laid over old silicone and failed
- Failed sealant around rooflight glass
Letting a property close to Edinburgh Waverley station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many joints need doing, and the area is left clean. Inside a flat in Prestonfield, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
