Should I try it myself 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.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How we handle glazing silicone in St Fillans
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we’ll tell you. Common call-outs are for rooflight joints letting water in and leaks from the base of a shower screen, on shower screens, glass balustrade bases and glass-to-frame joints.
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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What we do, step by step
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most jobs. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- 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 parking rules near the property
- Move anything stored near the joints
- Mention any tricky access
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Advice
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Look over the glazing joints once a year
- Use gentle products around the joints
- Open vents or windows to let moisture out
- Wipe the screen down after showering
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.

Common problems we fix in St Fillans
Heat and cold make glass and frames move, and they don’t move by the same amount. Over years, that movement tears the silicone.
The problems people generally mention when they call include:
- Black or yellowed silicone on glass joints
- Water tracking down the inner face of the glass
- Cracked silicone between glass panels
- Water escaping where a screen meets the wall
In and around St Fillans, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- How long to leave it before use
- What product goes in the joint
- How hidden problems are handled
- Who turns up on the day
Different surfaces, different methods
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Conservatory frames
Exposed frame joints wear with the weather. Renewed sealant keeps water out.
Quotes for glazing silicone in St Fillans
The price is agreed before any work begins. It’s based on:
- How many rooms, windows or areas are involved
- Whether the work is at height
- The size of the job
- Any mould that needs treating
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- The rough size of the job
- The type of property
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

St Fillans homes and 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. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In the older streets around Church Of The Holy Spirit, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
