- Old sand mastic that has cracked, crumbled or fallen out
- Open joints round the window box
- Mastic that needs renewing before redecorating
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid heavy scraping on the mastic joint
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
- Sort the mastic before the decorators arrive
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
About our sand mastic in Letham
We work across Letham renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. Common call-outs are for modern sealant on a period surround and crumbling sand mastic round a window, on sash and case windows, timber door frames and tenement windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Letham homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
Letting a property close to Perth station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Perth High School, the mastic around its windows and doors needs looking after like any other building’s.

Why act early in Letham
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us

- Old, loose mastic is raked out and the joint cleaned.
- 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.
- We dress the surface so it sits neatly against the masonry.
How to prepare

- Move anything stored near the joints
