Sand mastic in Churchill, done properly
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on timber door frames, period & listed homes and tenement windows, and people most often call us about silicone on a period window that looks wrong and patchy fillers round a sash window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Churchill is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

How it works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Churchill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- Go gently near the mastic when preparing windows
- Look over the window mastic once a year
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sand mastic in Churchill: local notes
With historic houses such as Chastleton House (about 3.8 miles north-west) nearby, there’s older building stock in the area around Churchill as well as newer homes. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Kingham station, any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Kingham Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
