How we handle sand mastic in Haywood
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We’re often asked to deal with modern sealant on a period surround and old cement repairs round a window that have failed, across period & listed homes, timber door frames and sash and case windows.
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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Sand mastic in Haywood: 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Rented homes near Breich station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Around Haywood, as everywhere, sand mastic is only as good as the preparation behind it.

What affects the cost of sand mastic
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Advice
Surface by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
How to look after the new joints
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
