Sand mastic for sash & case windows in Clackmannan, Clackmannanshire
Problem with your window and door surrounds in Clackmannan? We remove the old material, prepare the joints and seal them properly.
- Failed mastic on an exposed elevation
- Gaps round a timber door in stone or brick
- Old cement repairs round a window that have failed
How we handle sand mastic in Clackmannan
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include mastic round period door frames that has failed and window mastic to renew ahead of painting, on sash and case windows, timber door frames and stone surrounds.
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.
All our work comes with a 12-month guarantee.

DIY sealant or a professional job?
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.
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. Outside jobs in Clackmannan need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Why it’s worth doing now in Clackmannan
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Clackmannan, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
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.

What sand mastic looks like in Clackmannan
Clackmannan is within about 2 miles of 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 sound outside sealant is part of that.
Homes close to Parish Church and Churchyard include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Alloa station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
