External mastic for homes and businesses in Postling Green
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on joints between brick and frames, copings & trims and façade panels, and common reasons people get in touch are damp patches traced to an open external joint and sealant that has lost its bond to the brick or render.
In a village or hamlet like Postling Green, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid pressure-washing directly into sealant joints
- Have failed joints looked at early
- Deal with leaking gutters that soak the joints below
- Look over the joints every year, ideally after winter
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Postling Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Signs you need external mastic in Postling Green
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
Common reasons people contact us are:
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
For landlords with property near Westenhanger station, split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book

- Is VAT in the price?

Outside joints around Postling Green

Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Martin, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Aldington Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
