Glazing silicone in Newtown St Boswells, done properly
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. If you have drips on the inside of a conservatory window and leaks from the base of a shower screen, we can help, on glass-to-glass joints, conservatory frames and shower screens alike.
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.
Big or small, it’s backed by our 12-month guarantee.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Stick to mild cleaners on glass
- Check the gutters above the glazing for debris
- Wipe the screen down after showering
- Do not leave a drip for the next storm
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with straight away.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Your questions about glazing silicone in Newtown St Boswells
Will you come out to Newtown St Boswells?
Yes, Newtown St Boswells is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Newtown St Boswells for glazing silicone?
Yes. We work across all of Scotland, and Newtown St Boswells is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Do you replace glass?
That’s not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Do you need glazing silicone in Newtown St Boswells?
New silicone over old silicone will not bond. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Any of these means the joints need attention:
- Water escaping where a screen meets the wall
- Sealant that was laid over old silicone and failed
- Water getting into a conservatory at the joints
- Black or yellowed silicone on glass joints
If you let a flat or house near Tweedbank station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Frames and glazing around Newtown St Boswells
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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you look after a building such as Newtown Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
