Signs you need sand mastic in Itchingfield
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Most people get in touch after spotting something like this:
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
- Modern sealant on a period surround
- Cracked mastic round a front door frame
If you look after a building such as Barns Green Primary School, the mastic around its windows and doors needs looking after like any other building’s.

How we handle sand mastic in Itchingfield
We work across Itchingfield renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you’re dealing with gaps where the frame meets the masonry and cement or filler used on old window joints that has cracked, we can put it right, whatever the surface.
In a village or hamlet like Itchingfield, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, large or small.

What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Whether work needs listed building consent
- Sashes that need overhauling
- Damaged stone surrounds
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Timber door frames
- Period & listed homes
- Stone surrounds
- Brick reveals
- Sash and case windows
- Tenement windows
Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Sand mastic in Itchingfield: local notes

Letting a property close to Christs Hospital station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around The Parish Church of St Nicolas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Advice
How to look after the new joints
To keep the joints looking good and working properly:
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Common questions in Itchingfield

Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
