What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours for a single window, longer for several. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

What sand mastic looks like in Grandtully
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional 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 an older house near a landmark such as Strathtay Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Pitlochry station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Plan mastic work ahead of painting
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
- Get any rot dealt with first
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Sashes that need overhauling
- Rotten sashes, sills or window boxes (a joiner’s job)
- Masonry that needs repairing
