Sand Mastic in Ewhurst
Problem with your window and door surrounds in Ewhurst? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Silicone on a period window that looks wrong
- Cracked mastic round a front door frame
- Mastic dropping out of the joint
How we handle sand mastic in Ewhurst
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you have mastic worn away on windows facing the weather and crumbling sand mastic round a window, we can help, whatever the surface.
Around Ewhurst, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How it works
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for a single window, longer for several, depending on the size of the job. Somewhere as small as Ewhurst, 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.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Leave the new mastic unpainted
- Avoid heavy scraping on the mastic joint
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.

Ewhurst homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Ockley station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
