Sand mastic in Bells Yew Green, done properly
Silicone on a period window often looks wrong and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and wind and rain getting in round a sash window, we can help.
Mastic can only go onto a dry, clean joint, so window work in Bells Yew Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Frames and glazing around Bells Yew Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Wadhurst Castle (about 3 miles south-east) nearby, there’s older building stock in the area around Bells Yew Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In a small place like Bells Yew Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
