How to look after the new joints
After the cure time, these simple habits help:
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
- Do not run silicone over sand mastic
- Ask a joiner to look at soft timber first
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
How we handle sand mastic in Scragged Oak
Across Scragged Oak, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have silicone on a period window that looks wrong and patchy fillers round a sash window, we can put it right, whatever the surface.
In a village or hamlet like Scragged Oak, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. Where a wall is exposed, as many are in small places like Scragged Oak, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

How the job changes by surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Scragged Oak 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. With historic houses such as Stoneacre (about 4.8 miles south) nearby, there’s older building stock in the area around Scragged Oak as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Bearsted station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
