Frames and glazing around Littlestead Green
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. Historic houses like Mapledurham House (about 3.9 miles west) are a reminder that the area around Littlestead Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Reading station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as St Martin's Catholic Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
So the new joints stay in good condition:
- Clear gutters so water does not pour onto the windows
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why it’s worth doing now in Littlestead Green
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Littlestead Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
