About our sand mastic in Hightown
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We are often asked to deal with tired mastic found when preparing windows for paint and mastic round period door frames that has failed, on timber door frames, tenement windows and stone surrounds.
Homes in small places like Hightown often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months, in Hightown and everywhere else we cover.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Avoid heavy scraping on the mastic joint
- Have rotten timber repaired before new mastic goes in
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

What sand mastic looks like in Hightown
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Avon Tyrrell House (about 3 miles south) nearby, there’s older building stock in the area around Hightown as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
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.
How the job changes by surface
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Period and listed homes
A traditional finish suits a period property.
The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a single window, longer for several for a typical job. In a small place like Hightown, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in

Do you need sand mastic in Hightown?
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
These are the problems we’re asked about most:
- Mastic round period door frames that has failed
- Draughts and rain around sash boxes
- Cement or filler used on old window joints that has cracked
- Modern sealant on a period surround
If you look after a building such as Ringwood Junior School, larger buildings have plenty of frames, and the mastic around each one ages.
