How we handle sand mastic in Brabourne Lees
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. Typical jobs include draughty sash windows at the surround and patchy fillers round a sash window, across stone surrounds, timber door frames and period & listed homes.
Homes in small places like Brabourne Lees often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, it’s backed by our one-year guarantee in Brabourne Lees and across Kent.

Why it’s worth doing now in Brabourne Lees
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Brabourne Lees, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
- Clear gutters so water does not pour onto the windows
- Check the mastic when you check the paintwork
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Brabourne Lees 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 Westenhanger Castle (about 3.2 miles south-east) nearby, there’s older building stock in the area around Brabourne Lees as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Smeeth Community Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.
