How the job changes by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
Sand mastic in Holton
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you’re dealing with mastic dropping out of the joint and draughty sash windows at the surround, we can help.
In a village or hamlet like Holton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Why act early in Holton
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Holton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
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.
Frames and glazing around Holton
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Garsington Manor (about 3.1 miles south) are a reminder that the area around Holton has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Wheatley Park School, the mastic around its windows and doors needs looking after like any other building’s.

What else we do in Holton
Common problems we fix in Holton
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
If you live in an older home near The Granary Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
