Sand mastic in Shipton-under-Wychwood, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you are dealing with wind and rain getting in round a sash window and modern sealant on a period surround, we can put it right.
In a village or hamlet like Shipton-under-Wychwood, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same 12-month guarantee.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Shipton-under-Wychwood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

- Whether old sealant or filler has to be cut out
- The product the joint needs
- The size of the job
- Access and height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Ask a joiner to look at soft timber first
- Leave the new mastic unpainted
- Go gently near the mastic when preparing windows
- Do not run silicone over sand mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
What sand mastic looks like in Shipton-under-Wychwood
Historic houses like Minster Lovell Hall (about 5 miles south-east) are a reminder that the area around Shipton-under-Wychwood has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Wychwood Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Shipton station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

People normally contact us after spotting one of these:
- Draughts and rain around sash boxes
- Old cement repairs round a window that have failed
- Mastic round period door frames that has failed
- Modern sealant on a period surround
For an older house near a landmark such as Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Shipton-under-Wychwood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
