How we handle sand mastic in Hyde End
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We’re often asked to deal with patchy fillers round a sash window and mastic round period door frames that has failed, across brick reveals, sash and case windows and period & listed homes.
Around Hyde End, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months.

Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Hyde End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before we start.

Surface by surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep modern sealant off the mastic
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
- Look over the window mastic once a year
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

- Whether there’s mould to deal with

Sand mastic in Hyde End: local notes
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.
Managing a site like Brimpton C.E. Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Midgham station, any sash windows need sound mastic to keep draughts and rain out.

What we are called out for in Hyde End
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Common reasons people contact us include:
- Tired mastic found when preparing windows for paint
- Draughty sash windows at the surround
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
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.
Before booking anyone
- When the joint can take water or movement
- Which colour the sealant will be
- What guarantee comes with the work
- Whether all the old sealant comes out first
What we can’t put right
To be straight with you, some problems need a different trade:
- Decayed frames that need repair
- Decisions on consent for listed homes
- Sashes that need overhauling
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
Surfaces we seal
