About our sand mastic in Biddenden Green
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on period & listed homes, tenement windows and stone surrounds, and people most often call us about tired mastic found when preparing windows for paint and gaps round a timber door in stone or brick.
Around Biddenden Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

Windows and doors in Biddenden Green
Compared with the north and west, the South East gets less rain, 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 Church of St Michael, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Smarden Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

The process
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a single window, longer for several, including the tidy-up. Somewhere as small as Biddenden Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children

DIY versus a professional finish
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Do you need sand mastic in Biddenden Green?
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Most people get in touch when they notice something like this:
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
- Wind and rain getting in round a sash window
For landlords with property near Pluckley station, any sash windows need sound mastic to keep draughts and rain out.

What the job involves on each surface
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep modern sealant off the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
Why it’s worth doing now in Biddenden Green
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Biddenden Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
