With historic houses such as Anne of Cleves House (about 3.7 miles south) nearby, there’s older building stock in the area around Chiltington as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

A traditional finish suits a period property, and sand mastic is one of them.
Stone surrounds

Common problems we fix in Chiltington
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Most people get in touch after spotting one of these:
- Tired mastic found when preparing windows for paint
- Gaps where the frame meets the masonry
- Mastic dropping out of the joint
- Old cement repairs round a window that have failed
Homes close to The Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.

Aftercare tips
A little care helps the new joints last. Our advice:
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
