How we handle sand mastic in South Newington
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on brick reveals, tenement windows and sash and case windows, and the jobs we see most are a silicone bead on a sash window that spoils the look and old sand mastic that has cracked, crumbled or fallen out.
Somewhere as small as South Newington, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, in South Newington and everywhere else we cover.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes a few hours per window, depending on the condition of the joints. For a village or hamlet like South Newington, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in South Newington and across Oxfordshire. We can quote a run of properties together.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
When to call us in South Newington
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Common reasons people contact us are:
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
Around South Newington, as everywhere, sand mastic is only as good as the preparation behind it.

South Newington homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Broughton Castle (about 3.1 miles north) are a reminder that the area around South Newington has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near St Peter ad Vincula, the joint between an old wall and a newer frame is usually the first place rain gets in.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Make sure water runs off the sill
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
- Look over the window mastic once a year
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
