Window mastic for homes and businesses in Great Yeldham
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have white mastic on grey or black frames and cracked sealant at the sill ends, we can put it right, whatever the surface.
Around Great Yeldham, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

Frames and glazing around Great Yeldham
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 Hedingham Castle (about 2.3 miles south-east) nearby, there’s older building stock in the area around Great Yeldham 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.
Schools such as St Andrew's Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Parish Church of St Andrew include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Clear any debris from frame drain holes
- Keep timber frames painted
- Wash the frames with mild soapy water
- Air rooms to keep condensation down around windows
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Where a wall is exposed, as many are in small places like Great Yeldham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
