- Open joints round the window box
- Failed mastic on an exposed elevation
- Patchy fillers round a sash window
How to look after the new joints
After the cure time, these simple habits help:
- Leave the new mastic unpainted
- Look over the window mastic once a year
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
How we handle sand mastic in Wingham
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on timber door frames, stone surrounds and brick reveals, and the jobs we see most are mastic worn away on windows facing the weather and old sand mastic that has cracked, crumbled or fallen out.
Around Wingham, 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 comes with our one-year guarantee, wherever you are in Kent.

Frames and glazing around Wingham

Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Wingham Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Adisham station, any sash windows need sound mastic to keep draughts and rain out.

What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic generally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.

Most people get in touch after spotting one of these:
- Mastic dropping out of the joint
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
If you live in an older home near St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Whether all the old sealant comes out first
- What product goes in the joint
- How the joint is cleaned and prepared
- Whether you can choose the colour
