Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Older cottages and farmhouses around Worth Abbey can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Do you need sand mastic in Worth Abbey?
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
The most common problems we see are:
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
Managing a site like Oriel High School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
- Renew mastic before redecorating the windows
- Leave the new mastic unpainted
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
