Sand mastic in Great Canney, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Common call-outs are for gaps between timber frames and stone or brick and silicone on a period window that looks wrong, on period & listed homes, sash and case windows and stone surrounds.
Homes in small places like Great Canney often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, it’s backed by our 12-month guarantee in Great Canney and across Essex.

How to look after the new joints
After the cure time, these simple habits help:
- Check the mastic when you check the paintwork
- Clear gutters so water doesn’t pour onto the windows
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.

Frames and glazing around Great Canney
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Cold Norton Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Parish Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Common questions in Great Canney
Do you cover Great Canney for sand mastic?
Yes, Great Canney is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Will you come out to Great Canney?
Yes, Great Canney is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How much does sand mastic cost in Great Canney?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Can you replace silicone on a period window with sand mastic?
Normally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Leave it or put it right?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Around Great Canney, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

- Sanitary silicone with an anti-fungal additive in wet areas
- More than 20 years in sealant work

What affects the cost of sand mastic
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- How many rooms, windows or areas are involved

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.
