How we handle sand mastic in Cornton
Across Cornton, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on period & listed homes, timber door frames and tenement windows, and common reasons people get in touch are modern sealant on a period surround and mastic round period door frames that has failed.
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.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

What sand mastic looks like in Cornton
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Wallace High School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. 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.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.

Do you need sand mastic in Cornton?
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Old cement repairs round a window that have failed
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
For landlords with property near Stirling station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before you book
- What insurance they hold
- Who does the work, and how experienced they are
- The length of the guarantee
- How the surfaces are prepared before sealing
How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. Outdoor work around Cornton depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Advice
For landlords and businesses
For anyone letting property in or around Cornton, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
DIY versus a professional finish
If you are set on DIY, put the effort into 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
