Sand mastic for sash & case windows in Gubbion's Green, Essex
We cover Gubbion's Green for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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 fails, we can still redo it.
Sand mastic in Gubbion's Green
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you have modern sealant on a period surround and mastic that needs renewing before redecorating, we can help, on sash and case windows, brick reveals and tenement windows alike.
In a village or hamlet like Gubbion's Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What we are called out for in Gubbion's Green
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Look out for any of the following:
- Gaps between timber frames and stone or brick
- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation
If you look after a building such as Great Leighs Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
After the cure time, these simple habits help:
- Make sure water runs off the sill
- Get any rot dealt with first
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. Left, the gap tends to get bigger.

Can old silicone round a sash window be swapped for sand mastic?

Do you do commercial work?

Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
