Sand mastic in Boyndie
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on timber door frames, tenement windows and sash and case windows, and common reasons people get in touch are window mastic to renew ahead of painting and gaps between timber frames and stone or brick.
Outdoor sealant needs a dry surface, so window work around Boyndie is planned around the weather. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, it’s backed by our one-year guarantee.

What sand mastic looks like in Boyndie
Boyndie is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Duff House (about 2.5 miles east) are a reminder that the area around Boyndie has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In and around Boyndie, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What we’re called out for in Boyndie
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Common reasons people contact us include:
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
Homes close to Parish Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
Questions to ask before you book
- Who turns up on the day
- When the joint can take water or movement
- Which colour the sealant will be
- What product goes in the joint
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Get any rot dealt with first
- Renew mastic before redecorating the windows
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.

Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What does sand mastic cost?

Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.

What affects the quote in Boyndie
Every job gets its own quote. These are the things that affect it:
- The old material and how stubborn it is
- Working hours on commercial sites
- Access and height
- Which sealant suits the joint
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
To make quoting easier, please include:
- How we’d reach the joints
- What’s wrong with the joints now
- Whether it’s a home or a business
- The rough size of the job
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Whether work needs listed building consent
- Sashes that need overhauling
- Cracked or broken glass
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
What we seal
- Timber door frames
- Stone surrounds
- Period & listed homes
- Sash and case windows
- Brick reveals
- Tenement windows
Leave it or put it right?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. In a place like Boyndie, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint normally makes the job bigger, not smaller, 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.

What else we do in Boyndie
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
