Cranbrook Common Sand Mastic
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for householders, landlords and businesses in Cranbrook Common. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Gaps between timber frames and stone or brick
- Draughty sash windows at the surround
- Mastic dropping out of the joint
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Older cottages and farmhouses around Cranbrook Common can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What you get with us
- Experience in homes, commercial sites and hotels
- An ARBOMaster approved applicator
- Arbo and Everbuild products
- We never seal over old sealant
About our sand mastic in Cranbrook Common
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. Common call-outs are for draughty sash windows at the surround and mastic dropping out of the joint, across tenement windows, brick reveals and timber door frames.
In a village or hamlet like Cranbrook Common, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee.

What else we do in Cranbrook Common
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
- Sort the mastic before the decorators arrive
- Have rotten timber repaired before new mastic goes in
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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 doesn’t work out, we can still put it right.
Cranbrook Common homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Staplehurst station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Cranbrook School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Are you fully insured?
Yes. We’re fully insured for every job we do.

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
