Why act early in Cousley Wood

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.

Frames and glazing around Cousley Wood
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. With historic houses such as Wadhurst Castle (about 1.6 miles south-west) nearby, there’s older building stock in the area around Cousley Wood as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Rehoboth Chapel, the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Wadhurst station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Uplands Community College are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
