Sand mastic in Ellen's Green
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on period & listed homes, timber door frames and brick reveals, and common reasons people get in touch are mastic worn away on windows facing the weather and gaps between timber frames and stone or brick.
Around Ellen's Green, 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.
There’s a 12-month guarantee on every job.

Different surfaces, different methods
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- Plan mastic work ahead of painting
- Avoid patching sand mastic with silicone
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

What happens on the day
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints in most cases. Somewhere as small as Ellen's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
