Sand mastic in Stenton
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on period & listed homes, tenement windows and timber door frames, and common reasons people get in touch are a silicone bead on a sash window that spoils the look and gaps between timber frames and stone or brick.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All our work comes with our one-year guarantee.

How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.

We protect the rest, and the job takes a few hours per window, depending on the condition of the joints in most cases.

- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit

What sand mastic looks like in Stenton
Stenton is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Letting a property close to East Linton station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Do you need sand mastic in Stenton?
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they normally need raking out.
Common reasons people contact us include:
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Mastic round period door frames that has failed
- Draughts and rain around sash boxes
Homes close to Stenton Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why act early in Stenton
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

FAQs for Stenton
Will you come out to Stenton?
Yes. Stenton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Stenton affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What does sand mastic cost?
Every job is different, so each one gets its own quote. To get one, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Damaged stone surrounds
- Putty and glazing repairs
- Timber that has rotted
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
