About our sand mastic in Lower Sheering
We work across Lower Sheering renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on stone surrounds, tenement windows and timber door frames, and common reasons people get in touch are failed mastic on an exposed elevation and wind and rain getting in round a sash window.
Somewhere as small as Lower Sheering, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee.

Why it’s worth doing now in Lower Sheering
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a small place like Lower Sheering, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Frames and glazing around Lower Sheering
With historic houses such as Barrington Hall (about 4.2 miles north-east) nearby, there’s older building stock in the area around Lower Sheering as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Sawbridgeworth station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Fawbert and Barnard Infants' School? Then its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Parish Church of Great St Mary's, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
