About our sand mastic in Millerston
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on brick reveals, tenement windows and sash and case windows, and people most often call us about draughty sash windows at the surround and tired mastic found when preparing windows for paint.
Mastic can only go onto a dry joint, so outside work in Millerston depends on the weather. Let us know about access to every frame, including any upstairs.
There’s a 12-month guarantee on every job.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to a full day, depending on how many windows. Outdoor work around Millerston depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic 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
- Let us know about stairs, lifts or work at height

Advice
Sand mastic in Millerston: local notes
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
If you look after a building such as Belmont House School, the mastic around its windows and doors needs looking after like any other building’s. Pollok House, about 4 miles north, is one of the historic houses in the wider area around Millerston, and older homes nearby need a sealant that suits their walls.

- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
- Timber that has rotted

Aftercare tips
To keep the joints looking good and working properly:
- Don’t paint over the new mastic
- Make sure water runs off the sill
- Don’t run silicone over sand mastic
- Ask a joiner to look at soft timber first
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
