How we handle glazing silicone in Newtongrange
Sealant on glazing does not last for ever. Weather and movement take their toll and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on glass balustrade bases, glass-to-glass joints and rooflights, and common reasons people get in touch are stained, discoloured glazing silicone and leaks from the base of a shower screen.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job comes with a one-year guarantee, wherever you are in Midlothian.

Can you do several jobs on one visit?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Use gentle products around the joints
- Use a gentle glass cleaner and a soft cloth
- Squeegee the shower screen after each use
- Look over the glazing joints once a year
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Glazing silicone in Newtongrange: local notes
Historic houses like Melville Castle (about 2.3 miles north-west) are a reminder that the area around Newtongrange has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Managing a site like Newbattle Community High School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Newtongrange station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Do you need glazing silicone in Newtongrange?
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Signs it’s time to call us include:
- Conservatory leaks at frame and glazing joints
- Mouldy sealant around glass panels
- Leaks from the base of a shower screen
- Glazing silicone that has cracked or come away
For an older house near a landmark such as Newtongrange Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
