Sand mastic in Liverton Street
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We are often asked to deal with gaps between timber frames and stone or brick and tired mastic found when preparing windows for paint, on timber door frames, tenement windows and sash and case windows.
Around Liverton Street, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Sand mastic in Liverton Street: local notes
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. Historic houses like Leeds Castle (about 3.1 miles north-west) are a reminder that the area around Liverton Street has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Lenham station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. For a village or hamlet like Liverton Street, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Related advice
Different surfaces, different methods
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
What we’re called out for in Liverton Street
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
People usually contact us after spotting one of these:
- Cracked mastic round a front door frame
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
Schools such as Platts Heath Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Get any rot dealt with first
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
- Don’t paint over the new mastic
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
