Sand mastic in Brocketsbrae, done properly
We work across Brocketsbrae renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on tenement windows, brick reveals and timber door frames, and people most often call us about crumbling sand mastic round a window and window mastic to renew ahead of painting.
Mastic can only go onto a dry joint, so outside work in Brocketsbrae depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Sand mastic in Brocketsbrae: local notes
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 failed outside joints work against that.
For landlords with property near Lanark station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Lesmahagow High School, larger buildings have plenty of frames, and the mastic around each one ages.

Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

Is sand mastic better than silicone for my windows?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
