About our sand mastic in Petteridge
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on sash and case windows, tenement windows and brick reveals, and common reasons people get in touch are crumbling sand mastic round a window and gaps where the frame meets the masonry.
Somewhere as small as Petteridge, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You get a one-year guarantee, the same in Petteridge as everywhere else we work.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Find out about consent before window work on a listed home
- Avoid patching sand mastic with silicone
- Don’t paint over the new mastic
- Keep sills and gutters clear so water drains away
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Windows and doors in Petteridge
Historic houses like Scotney Castle (about 3.8 miles south) are a reminder that the area around Petteridge has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Brenchley and Matfield Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Ebenezer Church (Matfield), replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Paddock Wood station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Petteridge: your questions answered
Can you help a landlord with a rental near Paddock Wood station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Petteridge?
Yes. Petteridge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
