Sand mastic in Feering
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We are often asked to deal with a silicone bead on a sash window that spoils the look and open joints round the window box, across timber door frames, period & listed homes and stone surrounds.
Somewhere as small as Feering, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Every job comes with a one-year guarantee, wherever you are in Essex.

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a single window, longer for several. Somewhere like Feering needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

Advice
What we’re called out for in Feering
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint and we normally remove them.
These are the problems we are asked about most:
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
- Failed mastic on an exposed elevation
For site and facilities teams at buildings such as Feering Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Your questions about sand mastic in Feering
Is Feering within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Kelvedon station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We’ll tell you what to expect for your job.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Windows and doors in Feering
Historic houses like Layer Marney Tower (about 3.8 miles south-east) are a reminder that the area around Feering has older buildings as well as new. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Parish Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Kelvedon station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Around Feering, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Renew mastic before redecorating the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid patching sand mastic with silicone
- Make sure water runs off the sill
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
