Aftercare tips
So the new joints stay in good condition:
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
- Do not run silicone over sand mastic
- Make sure water runs off the sill
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

What sand mastic looks like in East Hoathly
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 Horselunges Manor (about 4.6 miles south-east) nearby, there’s older building stock in the area around East Hoathly as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around The Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like East Hoathly CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Uckfield station, any sash windows need sound mastic to keep draughts and rain out.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Why deal with it now?
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 East Hoathly can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
