About our glazing silicone in Thornliebank
Not every silicone suits glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. If you are dealing with stained, discoloured glazing silicone and shower screens leaking along the wall or tray, we can help, whatever the surface.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Thornliebank.
Each job carries a 12-month guarantee, whatever its size.

When to call us in Thornliebank
Silicone will not bond to a dirty surface. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Signs it’s time to call us include:
- Water running down inside the glass
- Stained, discoloured glazing silicone
- Leaks from the base of a shower screen
- Failed sealant around rooflight glass
Historic houses such as Pollok House, about 1.9 miles north, show how far back building around Thornliebank goes, and older homes nearby need a sealant that suits their walls.

What affects the quote in Thornliebank

- When we can work, for business premises
- The product the joint needs
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What glazing silicone looks like in Thornliebank
Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Windows usually belong to the flat, but the title deeds have the final say. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Schools such as Eastwood High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Whitecraigs station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Thornliebank: your questions answered
Who arranges sealant work on the shared parts of a tenement in Thornliebank?
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. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
I let a flat near Whitecraigs station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Do you fit new glass or sealed units?
We do not replace glass. We reseal the joints around it and can tell you if a unit seems to have gone.
Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Why not top up the existing silicone?
It does not last. Fresh silicone won’t bond to cured silicone, so we remove the old sealant and clean the joint.

What else we do in Thornliebank
Why act early in Thornliebank
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Private landlords in Thornliebank must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Keeping the joints in good condition
Aftercare is simple:
- Ventilate the conservatory to cut condensation
- Wipe the screen down after showering
- Use a gentle glass cleaner and a soft cloth
- Get a new leak looked at quickly
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
