What the job involves on each surface
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
How we handle glazing silicone in Letham
Glazing silicone is a maintenance item. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on glass balustrade bases, shower screens and glass-to-glass joints, and the jobs we see most are split or lifting silicone on glass and failed sealant around rooflight glass.
Mastic can only go onto a dry joint, so outside work in Letham depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Letham questions
Can you help a landlord with a rental near Perth station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Letham?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Is it enough to run a bead over the old sealant?
New silicone won’t bond to old silicone, so a top-up soon lets water through. We cut out the old sealant first.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Is the work guaranteed?
All our work has a 12-month guarantee.
What does glazing silicone cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for most jobs. Outside jobs in Letham need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

Looking after it afterwards
So the new joints stay in good condition:
- Keep harsh solvents off the silicone
- Keep scrapers and blades away from the silicone
- Check the gutters above the glazing for debris
- Clean glass with a mild cleaner and a soft cloth
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
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.

What glazing silicone looks like in Letham
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Perth High School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Perth station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Leave it or put it right?
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old and water soon finds its way back. A proper reseal is the lasting answer. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
