About our sand mastic in Wintershill
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. Typical jobs include open joints round the window box and old cement repairs round a window that have failed, on timber door frames, period & listed homes and sash and case windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Wintershill is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Wintershill as everywhere else we work.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What sand mastic looks like in Wintershill
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.
Schools such as Wyvern Technology College are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Clear gutters so water does not pour onto the windows
- Look over the window mastic once a year
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Wintershill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises

Work for landlords, hotels and businesses
