Sand mastic in Smarden, done properly
Across Smarden, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. Typical jobs include wind and rain getting in round a sash window and crumbling sand mastic round a window, across brick reveals, period & listed homes and sash and case windows.
Somewhere as small as Smarden, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Do you need sand mastic in Smarden?
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Keep an eye out for these signs:
- Modern sealant on a period surround
- Open joints round the window box
- Gaps round a timber door in stone or brick
- Wind and rain getting in round a sash window
If you let a flat or house near Pluckley station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. For a village or hamlet like Smarden, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

Related advice
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Your questions about sand mastic in Smarden
Is Smarden in your area for sand mastic?
Yes, Smarden is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Do you work for landlords with property near Pluckley station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Plan mastic work ahead of painting
- Avoid patching sand mastic with silicone
- Inspect the joints round the windows every year or so
- Don’t paint over the new mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.

Sand mastic in Smarden: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Smarden Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Michael, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why it’s worth doing now in Smarden
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In a small place like Smarden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
