Sand mastic for sash & case windows in Reading Street, Kent
We cover Reading Street for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Open joints round the window box
- Mastic round period door frames that has failed
- Window mastic to renew ahead of painting
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Have rotten timber repaired before new mastic goes in
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Sand mastic for homes and businesses in Reading Street
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. We work on timber door frames, tenement windows and stone surrounds, and people most often call us about mastic round period door frames that has failed and mastic that needs renewing before redecorating.
Around Reading 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.
All our work comes with a one-year guarantee, wherever you are in Kent.

Common problems we fix in Reading Street
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
It’s worth asking for a quote if you see:
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
Homes close to Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Advice
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Reading Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Frames and glazing around Reading Street
With historic houses such as Smallhythe Place (about 1.8 miles west) nearby, there’s older building stock in the area around Reading Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
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.
