Sand Mastic in Bitchet Green
We cover Bitchet Green for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.

- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
Sand mastic in Bitchet Green, done properly
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. Typical jobs include window mastic to renew ahead of painting and gaps between timber frames and stone or brick, across stone surrounds, tenement windows and sash and case windows.
Homes in small places like Bitchet Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Every job comes with our 12-month guarantee.

What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In a small place like Bitchet Green, 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 guesswork. That’s why we ask a few questions first.

FAQs for Bitchet Green
Can you help a landlord with a rental near Kemsing station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Bitchet Green?
Yes, Bitchet Green is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What information do you need?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Sand mastic in Bitchet Green: local notes
With historic houses such as Ightham Mote (about 1 mile south-east) nearby, there’s older building stock in the area around Bitchet Green as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Lawrence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as St Lawrence Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
What we do, step by step
At the end, we look at the finished work together. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do.

- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Clear gutters so water doesn’t pour onto the windows
- Have rotten timber repaired before new mastic goes in
- Plan mastic work ahead of painting
- Check with your local planning authority if your home is listed
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
When to call us in Bitchet Green
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
These are the problems we are asked about most:
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
- Modern sealant on a period surround
- Failed mastic on an exposed elevation
For landlords with property near Kemsing station, older sash windows in a rental need their mastic kept sound to keep the weather out.
