About our sand mastic in Broomhouse
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. Common call-outs are for mastic round period door frames that has failed and tired mastic found when preparing windows for paint, on timber door frames, tenement windows and sash and case windows.
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.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. Somewhere like Broomhouse may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

Looking after it afterwards
So the new joints stay in good condition:
- Don’t paint over the new mastic
- Renew mastic before redecorating the windows
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
Frames and glazing around Broomhouse
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that won’t mark it.
For site and facilities teams at buildings such as Bannerman High School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Baillieston station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near Baillieston St Andrew's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.

It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames generally get a flexible sealant.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
