Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Get any rot dealt with first
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Stonestreet Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Stonestreet Green homes and the weather
Historic houses like Westenhanger Castle (about 3.7 miles east) are a reminder that the area around Stonestreet Green 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Aldington Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Westenhanger station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
