Sand mastic in Shatterling, done properly
Across Shatterling, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you are dealing with tired mastic found when preparing windows for paint and a silicone bead on a sash window that spoils the look, we can help.
Somewhere as small as Shatterling, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Common questions in Shatterling
Can you do sand mastic in Shatterling?
Yes. We work across London and the South East, and Shatterling is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Can you help a landlord with a rental near Adisham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.

Other services in Shatterling
What sand mastic looks like in Shatterling
With historic houses such as Goodnestone Park (about 2.5 miles south) nearby, there’s older building stock in the area around Shatterling as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Mary's Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Wingham Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Can I do it myself?
If you do try it yourself, take your time over the 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What we can’t put right
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 rattle, stick or won’t open
- Cracked or broken glass
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. For a village or hamlet like Shatterling, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
