About our sand mastic in Manuden
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and modern sealant on a period surround, across tenement windows, timber door frames and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Manuden is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Aftercare tips
To keep the joints looking good and working properly:
- Make sure water runs off the sill
- Ask us before painting near the mastic
- Look over the window mastic once a year
- Keep modern sealant off the mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
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 suits the building and finishes neatly against the masonry. In a small place like Manuden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Your questions about sand mastic in Manuden
Can you do sand mastic in Manuden?

Will you come out to Manuden?

How long does sand mastic take to harden?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Is sand mastic better than silicone for my windows?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant, and we will explain why.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Manuden homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Stansted Mountfitchet station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Manuden Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is usually favoured.
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Whether work needs listed building consent
- Sashes that rattle, stick or will not open
- Damaged stone surrounds
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
