Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it and tidies the surround. We work on brick reveals, period & listed homes and stone surrounds, and common reasons people get in touch are old cement repairs round a window that have failed and mastic round period door frames that has failed.
Around East Street, 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.

Aftercare tips
After the cure time, these simple habits help:
- Find out about consent before window work on a listed home
- Check the mastic when you check the paintwork
- Have rotten timber repaired before new mastic goes in
- Renew mastic before redecorating the windows
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Honest limits
In fairness, there are a few things sealant will not fix:
- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Leave it or put it right?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around East Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Goodnestone Park (about 4.3 miles south-west) are a reminder that the area around East 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’s traditional sand mastic.

Homes close to Church of St Nicholas include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
