Sand mastic for homes and businesses in Stone Corner
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you’re dealing with gaps round a timber door in stone or brick and draughts and rain around sash boxes, we can put it right.
Around Stone Corner, 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Do you have insurance?

How long does sand mastic take to harden?
Not right away. The skin forms first, and the full set comes later and we will give you an idea for your job.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Looking after it afterwards
So the new joints stay in good condition:
- Keep sills and gutters clear so water drains away
- Do not paint over the new mastic
- Sort the mastic before the decorators arrive
- Check the mastic when you check the paintwork
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Stone Corner homes and the weather
Historic houses like Smallhythe Place (about 1.4 miles north-west) are a reminder that the area around Stone Corner has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Smallhythe Place, about 1.4 miles north-west, is one of the historic houses in the wider area around Stone Corner. If you let a flat or house near Appledore (Kent) station, older sash windows in a rental need their mastic kept sound to keep the weather out.
