Sand mastic in Yarrowford
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 older homes, it suits the building far better than silicone. If you are dealing with mastic round period door frames that has failed and mastic worn away on windows facing the weather, we can help, whatever the surface.
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.
Every job comes with a one-year guarantee.

Questions from Yarrowford
Is sand mastic in Yarrowford guaranteed?

Is Yarrowford in your area for sand mastic?
Yes. We work across all of Scotland, and Yarrowford is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
How long will you be here?
A typical job takes a few hours per window, depending on the condition of the joints. Your quote will say how long we expect yours to take.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Yarrowford.
Which is right for my windows, sand mastic or modern sealant?
We will help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
How the job changes by surface
Timber door frames
Round a period front door, sand mastic gives the right look.
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
What we can’t put right

Aftercare tips
After the cure time, these simple habits help:
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
- Look over the window mastic once a year
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on the size of the job. For a place like Yarrowford, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Move anything stored near the joints
