About our sand mastic in Telham
We work across Telham renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on sash and case windows, stone surrounds and brick reveals, and people most often call us about open joints round the window box and a silicone bead on a sash window that spoils the look.
Somewhere as small as Telham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sand mastic in Telham: local notes
Historic houses like Durhamford Manor (about 2.4 miles north) are a reminder that the area around Telham 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. 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.
Letting a property close to Battle station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Claverham Community College, its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.

Signs you need sand mastic in Telham
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
Common reasons people contact us include:
- Crumbling sand mastic round a window
- Window mastic to renew ahead of painting
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
For an older house near a landmark such as Chapel of the Ascension, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
