How we handle sand mastic in Wanshurst Green
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We are often asked to deal with cement or filler used on old window joints that has cracked and open joints round the window box, across timber door frames, sash and case windows and stone surrounds.
Around Wanshurst Green, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
Looking after new joints is easy:
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Why act early in Wanshurst Green
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Wanshurst Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What sand mastic looks like in Wanshurst Green
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Marden station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Different surfaces, different methods
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.
When to call us in Wanshurst Green
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
It’s worth asking for a quote if you see:
- Draughts and rain around sash boxes
- Mastic dropping out of the joint
- Gaps between timber frames and stone or brick
- Window mastic to renew ahead of painting
Homes close to St Michael and All Angels Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
