Sand mastic in Tongland, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. We work on period & listed homes, stone surrounds and tenement windows, and the jobs we see most are draughty sash windows at the surround and cement or filler used on old window joints that has cracked.
Mastic can only go onto a dry joint, so outside work in Tongland depends on the weather. Tell us about access to all the windows and doors, upstairs included.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What sand mastic looks like in Tongland
Tongland is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
In the older streets around Tongland Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Tongland
Timber frames move with the seasons. The movement cracks the mastic over time.
If you can see any of these, it’s time to have the joints looked at:
- Draughty sash windows at the surround
- Gaps between timber frames and stone or brick
- Cracked mastic round a front door frame
- Weathered mastic on the most exposed windows
If you look after a building such as Kirkcudbright Academy, its window and door frames need their mastic kept sound, just like a home’s.

Questions from Tongland
Will you come out to Tongland?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is Tongland in your area for sand mastic?
Yes. We work across all of Scotland, and Tongland is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can you replace silicone on a period window with sand mastic?
Usually, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours per window, depending on the condition of the joints from start to finish. Around Tongland, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.

- The joint is raked out and cleaned.

- We finish the mastic to a tidy line.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
