Glazing silicone in Germiston
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. We are often asked to deal with new silicone smeared over old sealant and leaking glazing joints on a rooflight, across glass-to-glass joints, rooflights and shower screens.
Scotland’s cities are full of stone-built tenements and terraces, in 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 comes with our one-year guarantee.

Different surfaces, different methods
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Why act early in Germiston
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Private landlords in Germiston 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.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why Germiston clients choose us
- 12-month guarantee on every job
- You choose the colour before work begins

What we are called out for in Germiston
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
If you can see any of these, it’s time to have the joints looked at:
- Leaking glazing joints on a rooflight
- Cracked silicone between glass panels
- Shower screens leaking along the wall or tray
- Black or yellowed silicone on glass joints
Managing a site like St. Roch's Secondary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Your questions about glazing silicone in Germiston
Can you do glazing silicone in Germiston?
Yes, Germiston is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
How do repairs to the shared parts of a tenement in Germiston get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
How do I get a quote for glazing silicone in Germiston?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
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.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Where are you based?
We work from Crawley. Our applicators cover Germiston, along with the rest of our area.
Will resealing stop my conservatory leaking?
If the water is coming in through failed sealant joints, yes. If the cause is the roof, a panel or a unit, we will say so.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Look over the glazing joints once a year
- Clear the conservatory gutters regularly
- Do not leave a drip for the next storm
- Keep scrapers and blades away from the silicone
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
The process
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job generally takes a few hours for most jobs. Inside a flat in Germiston, 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 agree the joints to be done.

Before we arrive

Frames and glazing around Germiston
Historic houses like Provand's Lordship (about 1.2 miles south-west) are a reminder that the area around Germiston has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Glasgow’s tenements are largely red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
For an older house near a landmark such as Our Lady of Good Counsel Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Barnhill station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
