How we handle sand mastic in Arbuthnott
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on sash and case windows, tenement windows and brick reveals, and people most often call us about mastic round period door frames that has failed and modern sealant on a period surround.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. For a place like Arbuthnott, 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.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
- Don’t run silicone over sand mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.

Windows and doors in Arbuthnott
Arbuthnott 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you live in an older home near Arbuthnott Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full 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 lifts and traps water and mould underneath. Everything old must be removed first.
Your questions about sand mastic in Arbuthnott
Do you cover smaller places like Arbuthnott?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does living near the coast affect sand mastic in Arbuthnott?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What does sand mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
What we’re called out for in Arbuthnott
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they normally need raking out.
Signs it’s time to call us include:
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
- Old sand mastic that has cracked, crumbled or fallen out
Around Arbuthnott, as everywhere, sand mastic is only as good as the preparation behind it.
