Leave it or put it right?
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Stocker's Head, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Frames and glazing around Stocker's Head
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 Belmont House and Gardens (about 3.9 miles north) nearby, there’s older building stock in the area around Stocker's Head as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Charing station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in.

Signs you need sand mastic in Stocker's Head
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint and we normally remove them.
The most common problems we see are:
- Tired mastic found when preparing windows for paint
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
- Gaps between timber frames and stone or brick
Schools such as Charing Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
Aftercare is simple:
- Clear gutters so water doesn’t pour onto the windows
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
- Check the mastic when you check the paintwork
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
