Sand mastic in Great Totham, done properly
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on sash and case windows, brick reveals and tenement windows, and common reasons people get in touch are modern sealant on a period surround and mastic worn away on windows facing the weather.
Many houses in smaller places like Great Totham have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Get any rot dealt with first
- Clear gutters so water doesn’t pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Leave the new mastic unpainted
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Honest limits
We will not take on work that will not last, so here’s what sealant can’t put right:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that rattle, stick or will not open
- Damaged stone surrounds
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Should I try it myself first?
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 does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sand mastic in Great Totham: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Great Totham Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Witham station, older sash windows in a rental need their mastic kept sound to keep the weather out.

- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
