Frames and glazing around Freefolk
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Testbourne Community School, larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t paint over the new mastic
- Avoid patching sand mastic with silicone
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Common questions in Freefolk
Do you cover Freefolk for sand mastic?
Yes. Our work covers London and the South East, and Freefolk is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Will you come out to Freefolk?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Should I use sand mastic or silicone?
Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant.
