About our sand mastic in Broad Tenterden
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. We work on period & listed homes, stone surrounds and timber door frames, and people most often call us about mastic that needs renewing before redecorating and mastic round period door frames that has failed.
Homes in small places like Broad Tenterden 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 guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Broad Tenterden homes and the weather
With historic houses such as Smallhythe Place (about 1.6 miles south) nearby, there’s older building stock in the area around Broad Tenterden as well as newer homes. 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Parish Church of St Mildred, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What else we do in Broad Tenterden
Do you need sand mastic in Broad Tenterden?
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Most people get in touch when they notice one of these:
- Open joints round the window box
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
Managing a site like Tenterden Church of England Junior School? Then its window and door frames need their mastic kept sound, just like a home’s.
Comparing quotes

- How long the guarantee is
- Whether all the old sealant comes out first
- Whether they’re fully insured
What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Broad Tenterden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear price for the lot.
