How we handle sand mastic in Waterside
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on tenement windows, timber door frames and stone surrounds, and common reasons people get in touch are modern sealant on a period surround and gaps between timber frames and stone or brick.
Outdoor sealant needs a dry surface, so window work around Waterside is planned around the weather. Let us know about access to every frame, including any upstairs.
All of our work is guaranteed for twelve months.

Frames and glazing around Waterside
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to Waterside and Lethanhill Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Leave it or put it right?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
