About our sand mastic in Burghfield
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. If you’re dealing with gaps between timber frames and stone or brick and mastic that needs renewing before redecorating, we can put it right.
Homes in small places like Burghfield often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee.

Sand mastic in Burghfield: local notes
With historic houses such as Stratfield Saye House (about 4.8 miles south-east) nearby, there’s older building stock in the area around Burghfield as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Burghfield St Mary's C.E. Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the job changes by surface
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Clear gutters so water doesn’t pour onto the windows
- Sort the mastic before the decorators arrive
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
What happens if it’s left?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Around Burghfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.

Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
