Sand Mastic in Marks Tey
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for householders, landlords and businesses in Marks Tey. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Wind and rain getting in round a sash window
- Silicone on a period window that looks wrong
- Cement or filler used on old window joints that has cracked
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sand mastic in Marks Tey, done properly
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We work on tenement windows, brick reveals and timber door frames, and common reasons people get in touch are failed mastic on an exposed elevation and mastic that needs renewing before redecorating.
Somewhere as small as Marks Tey, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Advice
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. Left, the gap tends to get bigger.

Sand mastic in Marks Tey: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Layer Marney Tower (about 3.9 miles south) are a reminder that the area around Marks Tey has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Marks Tey station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Church of St Andrew, the joint between an old wall and a newer frame is normally the first place rain gets in.
