Signs you need sand mastic in Edgehill
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Cracked mastic round a front door frame
- Gaps where the frame meets the masonry
- Old cement repairs round a window that have failed
Around Edgehill, as everywhere, sand mastic is only as good as the preparation behind it.

Sand mastic in Edgehill, done properly
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Common call-outs are for a silicone bead on a sash window that spoils the look and mastic that needs renewing before redecorating, across sash and case windows, tenement windows and period & listed homes.
Somewhere as small as Edgehill, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months.

Your questions about sand mastic in Edgehill
Will you come out to Edgehill?
Yes, Edgehill is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do sand mastic in Edgehill?
Yes, Edgehill is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
How long does the job take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we’ll say how long yours will take.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Edgehill and the rest of Oxfordshire, along with the rest of our area.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Around Edgehill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Windows and doors in Edgehill
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. With historic houses such as Upton House (about 1 mile south) nearby, there’s older building stock in the area around Edgehill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

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
- Inspect the joints round the windows every year or so
- Get any rot dealt with first
- Make sure water runs off the sill
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
