About our sand mastic in Littleworth Corner
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you are dealing with mastic that needs renewing before redecorating and gaps between timber frames and stone or brick, we can put it right, whatever the surface.
Around Littleworth Corner, 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.
Each job carries a 12-month guarantee.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What else we do in Littleworth Corner
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Don’t run silicone over sand mastic
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Signs you need sand mastic in Littleworth Corner
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they generally need raking out.
Common reasons people contact us are:
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
- Mastic that needs renewing before redecorating
- Mastic worn away on windows facing the weather
If you look after a building such as Dropmore Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

What sand mastic looks like in Littleworth Corner
Historic houses like Cliveden (about 1.6 miles west) are a reminder that the area around Littleworth Corner has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Anne include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Bourne End station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In a small place like Littleworth Corner, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
