Window mastic in Westwell Leacon, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with gaps where the sill meets the wall and gaps between the frame and the inside reveal, we can help, on uPVC windows, composite doors and aluminium frames alike.
In a village or hamlet like Westwell Leacon, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Window mastic in Westwell Leacon: local notes
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. Historic houses like Godinton House (about 2.7 miles south-east) are a reminder that the area around Westwell Leacon 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 site and facilities teams at buildings such as The Hayesbrook School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Charing Methodist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Charing station, renewing tired window mastic between tenants heads off draught and damp complaints.

What’s near Westwell Leacon

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Avoid harsh chemicals near the mastic
- Clean frames with a soft cloth and soapy water
- Clear any debris from frame drain holes
- Keep paint off silicone joints
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.

Why it’s worth doing now in Westwell Leacon
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Westwell Leacon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
