About our sand mastic in Elvanfoot
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you’re dealing with old sand mastic that has cracked, crumbled or fallen out and failed mastic on an exposed elevation, we can put it right, on period & listed homes, timber door frames and tenement windows alike.
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.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. Around Elvanfoot, 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.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What is sand mastic?
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 it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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 doesn’t work out, we can still put it right.
What happens if it’s left?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Anti-fungal silicone where joints get wet

What we are called out for in Elvanfoot
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
These are the problems we’re asked about most:
- Mastic worn away on windows facing the weather
- Crumbling sand mastic round a window
- Window mastic to renew ahead of painting
- Gaps where the frame meets the masonry
In and around Elvanfoot, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- The length of the guarantee
- Is VAT in the price?
- Whether all the old sealant comes out first
- Whether you can choose the colour
Frames and glazing around Elvanfoot
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For jobs in and around Elvanfoot, choosing the right material for each joint is as important as a tidy finish.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep modern sealant off the mastic
- Look over the window mastic once a year
- Ask us before painting near the mastic
- Go gently near the mastic when preparing windows
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
