Glazing silicone in Charleston
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. If you’re dealing with glazing silicone that has cracked or come away and cracked silicone between glass panels, we can help, whatever the surface.
Charleston 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 will not mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Every job is covered by a one-year guarantee.

For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Why it’s worth doing now in Charleston
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Charleston, damp can travel a long way before it shows.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- Colour agreed with you before any work starts
- Any old sealant cut out fully, not covered over
- Every job guaranteed for a year
- An ARBOMaster approved applicator

Charleston homes and the weather
Charleston is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Dundee’s older tenements are sandstone, and the city sits on the Firth of Tay.
If you let a flat or house near Invergowrie station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Menzieshill High School, its window and door frames need their mastic kept sound, just like a home’s.

Charleston: your questions answered
Can you help a landlord with a rental near Invergowrie station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How do repairs to the shared parts of a tenement in Charleston get organised?
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.
Are you fully insured?
Yes. We’re fully insured.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you guarantee glazing sealant work?
Every job comes with our one-year guarantee.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will resealing stop my conservatory leaking?
Often, if the leak is at a sealant joint. We trace the leak first before any sealing.
Can you replace a misted double-glazed unit?
No. A misted unit has failed inside and needs replacing by a glazier.
What affects the cost of glazing silicone
We do not publish a price list. What we look at:
- How easy the joints are to reach
- Any mould that needs treating
- The size of the job
- The number of rooms or windows
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
Helping us quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
Every job is quoted individually, so the first step is telling us about yours. Just email us at info@mrmastic.co.uk with the details and send photos if you have them.
How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to most of a day, depending on the size of the job for a typical job. In a city area like Charleston, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Common problems we fix in Charleston
Some conservatory leaks are not sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That’s why we trace the leak first.
Keep an eye out for any of the following:
- Glazing silicone that has cracked or come away
- Leaks where conservatory glass meets the frame
- Mouldy sealant around glass panels
- Water running down inside the glass
In the older streets around Lochee Baptist Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- What guarantee comes with the work
- Who turns up on the day
- When the joint can take water or movement
- What product goes in the joint
How to look after the new joints
So the new joints stay in good condition:
- Do not use a blade near the sealant
- Check the silicone on glass every year or so
- Ventilate the conservatory to cut condensation
- Use gentle products around the joints
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.
