Sand mastic in Thames View Estate, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We’re often asked to deal with window mastic to renew ahead of painting and weathered mastic on the most exposed windows, across stone surrounds, brick reveals and tenement windows.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Thames View Estate.
We stand behind the work with a 12-month guarantee.

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

Advice
How to look after the new joints
A little care helps the new joints last. Our advice:
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
- Do not paint over the new mastic
- Make sure water runs off the sill
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Crumbling stone or brickwork round the window
- Cracked or broken glass
- Whether work needs listed building consent
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

When to call us in Thames View Estate
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they normally need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
- Open joints round the window box
- Mastic worn away on windows facing the weather
If you look after a building such as Thames View Infants, larger buildings have plenty of frames, and the mastic around each one ages.
