Sand mastic in Alyth
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. Typical jobs include cement or filler used on old window joints that has cracked and open joints round the window box, on tenement windows, timber door frames and period & listed homes.
In and around a place like Alyth, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.

What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Sand mastic in Alyth: 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. With historic houses such as Balhary House (about 1.6 miles south-east) nearby, there’s older building stock in the area around Alyth as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Around Alyth, as everywhere, sand mastic is only as good as the preparation behind it. If you live in an older home near Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
