Advice
Sand mastic for homes and businesses in Sandhurst Cross
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you’re dealing with a silicone bead on a sash window that spoils the look and window mastic to renew ahead of painting, we can help, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Sandhurst Cross is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Why deal with it now?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Sandhurst Cross, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Keeping the joints in good condition
Looking after new joints is easy:
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
- Ask a joiner to look at soft timber first
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
What we’re called out for in Sandhurst Cross
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Signs it’s time to call us include:
- Patchy fillers round a sash window
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
- Wind and rain getting in round a sash window
If you let a flat or house near Robertsbridge station, any sash windows need sound mastic to keep draughts and rain out.

What else we do in Sandhurst Cross
Sandhurst Cross homes and the weather
With historic houses such as Great Dixter (about 2.5 miles south-east) nearby, there’s older building stock in the area around Sandhurst Cross as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For an older house near a landmark such as Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Sandhurst Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
