About our sand mastic in Shover's Green
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. Common call-outs are for gaps between timber frames and stone or brick and cracked mastic round a front door frame, on sash and case windows, period & listed homes and tenement windows.
Around Shover's Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, you get the same 12-month guarantee in Shover's Green and across East Sussex.

Advice
Sand mastic in Shover's Green: local notes
Historic houses like Wadhurst Castle (about 1.6 miles north-west) are a reminder that the area around Shover's Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Uplands Community College, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Shover's Green Baptist Chapel, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Stonegate station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Common questions in Shover's Green
Is Shover's Green within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do sand mastic in Shover's Green?
Yes, Shover's Green is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will advise.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Should I use sand mastic or silicone?
Sand mastic generally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
When will the new mastic be hard?
It takes a while. The skin forms first, and the full set comes later and we will give you an idea for your job.
Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In a small place like Shover's Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
- Sort the mastic before the decorators arrive
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
DIY versus a professional finish
The difference is mostly in the preparation and the 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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- How easy the joints are to reach
