How we handle sand mastic in Lochmaben
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. If you have mastic worn away on windows facing the weather and crumbling sand mastic round a window, we can help.
Mastic can only go onto a dry joint, so outside work in Lochmaben depends on the weather. Let us know about access to every frame, including any upstairs.
Big or small, you get the same one-year guarantee.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What sand mastic looks like in Lochmaben
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. 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 landlords with property near Lockerbie station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What happens on the day

- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.

Keeping the joints in good condition
Looking after new joints is easy:
- Find out about consent before window work on a listed home
- Take care around the mastic when scraping paint
- Renew mastic before redecorating the windows
- Keep modern sealant off the mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
