About our sand mastic in Milcombe
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We’re often asked to deal with draughty sash windows at the surround and mastic worn away on windows facing the weather, on brick reveals, tenement windows and period & listed homes.
In a village or hamlet like Milcombe, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months.

A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.

What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Milcombe homes and the weather
With historic houses such as Broughton Castle (about 2.2 miles north) nearby, there’s older building stock in the area around Milcombe as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Banbury 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 Lawrence, the joint between an old wall and a newer frame is normally the first place rain gets in.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Take care around the mastic when scraping paint
- Get any rot dealt with first
- Leave the new mastic unpainted
- Don’t run silicone over sand mastic
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
