Hinchley Wood homes and the weather
With historic houses such as Hampton Court Palace (about 1.9 miles north) nearby, there’s older building stock in the area around Hinchley 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Hinchley Wood Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Hinchley Wood station, any sash windows need sound mastic to keep draughts and rain out.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Have rotten timber repaired before new mastic goes in
- Plan mastic work ahead of painting
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Do you need sand mastic in Hinchley Wood?
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
It’s worth asking for a quote if you see:
- Modern sealant on a period surround
- Open joints round the window box
- Failed mastic on an exposed elevation
- Draughts and rain around sash boxes
Homes close to Hinchley Wood Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
