Sand mastic for sash & case windows in West End, South Lanarkshire
Sand mastic across West End and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Silicone on a period window that looks wrong
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
What happens if it’s left?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. 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.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Sand mastic in West End, done properly
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you have crumbling sand mastic round a window and failed mastic on an exposed elevation, we can put it right, 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.
All our work is covered by a 12-month guarantee.

Your questions about sand mastic in West End
Do you work for landlords with property near Carstairs station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Will you come out to West End?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What do you need from me for a quote?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
How long does sand mastic take?
That depends on how much there is to do, but as a guide it takes a few hours for a single window, longer for several. We’ll give you a better idea when we quote.

What sand mastic looks like in West End
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Carstairs station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Aftercare tips
Aftercare is simple:
- Keep modern sealant off the mastic
- Check the mastic when you check the paintwork
- Have rotten timber repaired before new mastic goes in
- Go gently near the mastic when preparing windows
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
What we can’t put right
A few problems are outside what sealant work can do:
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.
