Holton Hill Sand Mastic
Problem with your window and door surrounds in Holton Hill? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
- Wind and rain getting in round a sash window
How to look after the new joints
To keep the joints looking good and working properly:
- Have rotten timber repaired before new mastic goes in
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
About our sand mastic in Holton Hill
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on period & listed homes, sash and case windows and timber door frames, and people most often call us about old cement repairs round a window that have failed and gaps between timber frames and stone or brick.
Mastic can only go onto a dry, clean joint, so window work in Holton Hill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, in Holton Hill and everywhere else we cover.

Sand mastic in Holton Hill: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Bateman's (about 0.9 miles south-east) nearby, there’s older building stock in the area around Holton Hill as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Stonegate station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Burwash CofE School, its window and door frames need their mastic kept sound, just like a home’s.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why act early in Holton Hill
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Holton Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What we’re called out for in Holton Hill
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
People generally contact us after spotting something like this:
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
For an older house near a landmark such as The Parish Church of St Bartholomew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
