Sand mastic for homes and businesses in Shieldhill
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. We work on period & listed homes, stone surrounds and tenement windows, and people most often call us about failed mastic on an exposed elevation and mastic dropping out of the joint.
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.
You get a 12-month guarantee, the same in Shieldhill as everywhere else we work.

How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. Outside jobs in Shieldhill need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

Related advice
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. In an older home around Shieldhill, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
For anyone letting property in or around Shieldhill, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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. All the old material has to come out first.
Frames and glazing around Shieldhill
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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Graeme High School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Falkirk High station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Sort the mastic before the decorators arrive
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
