What window mastic looks like in Winkfield Row
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as St Leonard's Hill (about 3.8 miles north-east) nearby, there’s older building stock in the area around Winkfield Row as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Winkfield St Mary's CofE Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Martin's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Do you need window mastic in Winkfield Row?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Common reasons people contact us include:
- Damp patches on the reveal after heavy rain
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- Cracked internal joints between frame and plaster
Rented homes near Martins Heron station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- How much experience the applicator has
- When the joint can take water or movement
- How the colour is chosen
- Is VAT in the price?
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Winkfield Row can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Air rooms to keep condensation down around windows
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
Silicone can’t generally be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. 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 careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
