Advice
Different surfaces, different methods
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
When to call us in South Ockendon
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Look out for these signs:
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
If you look after a building such as Bonnygate Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Windows and doors in South Ockendon
Historic houses like Rainham Hall (about 4.3 miles west) are a reminder that the area around South Ockendon has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Ockendon station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
