Sand mastic for homes and businesses in Hedgerley Green
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. If you have wind and rain getting in round a sash window and failed mastic on an exposed elevation, we can help, on stone surrounds, tenement windows and period & listed homes alike.
In a village or hamlet like Hedgerley Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

Signs you need sand mastic in Hedgerley Green
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
These are the problems we are asked about most:
- Cracked mastic round a front door frame
- Gaps where the frame meets the masonry
- Silicone on a period window that looks wrong
- Draughts and rain around sash boxes
If you live in an older home near Parish Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
- Whether VAT is included

What sand mastic looks like in Hedgerley Green
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Cliveden (about 4.5 miles west) nearby, there’s older building stock in the area around Hedgerley 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.
For site and facilities teams at buildings such as Gayhurst School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Gerrards Cross station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
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 blends with the stone or brick. Where a wall is exposed, as many are in small places like Hedgerley Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
