Sand mastic in Milstead
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We’re often asked to deal with modern sealant on a period surround and gaps between timber frames and stone or brick, on sash and case windows, tenement windows and timber door frames.
Around Milstead, 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.
Every job is covered by our one-year guarantee, wherever you are in Kent.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Clear gutters so water does not pour onto the windows
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Signs you need sand mastic in Milstead
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
Common reasons people contact us include:
- Gaps between timber frames and stone or brick
- Cracked mastic round a front door frame
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
For site and facilities teams at buildings such as Milstead and Frinsted Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Sand mastic in Milstead: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Sittingbourne station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Mary and the Holy Cross, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for a single window, longer for several. For a village or hamlet like Milstead, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
