About our sand mastic in Benenden
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you have old sand mastic that has cracked, crumbled or fallen out and modern sealant on a period surround, we can put it right.
In a village or hamlet like Benenden, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Your job is guaranteed for a year, as with all our work.

How the job changes by surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Which products do you use?

Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Frames and glazing around Benenden
Historic houses like Great Dixter (about 5 miles south) are a reminder that the area around Benenden 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Benenden Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep modern sealant off the mastic
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
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.
Signs you need sand mastic in Benenden
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint and we normally remove them.
People generally contact us when they notice something like this:
- Wind and rain getting in round a sash window
- Old cement repairs round a window that have failed
- Silicone on a period window that looks wrong
- Weathered mastic on the most exposed windows
Homes close to Church of St George include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
