Sand mastic for sash & case windows in Lamberhurst Quarter, Kent
Our applicators work in Lamberhurst Quarter on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Weathered mastic on the most exposed windows
- Silicone on a period window that looks wrong
- Draughts and rain around sash boxes
How we handle sand mastic in Lamberhurst Quarter
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. Common call-outs are for open joints round the window box and old sand mastic that has cracked, crumbled or fallen out, on brick reveals, tenement windows and timber door frames.
Somewhere as small as Lamberhurst Quarter, 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.

What the job involves on each surface
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In a small place like Lamberhurst Quarter, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Frames and glazing around Lamberhurst Quarter
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. With historic houses such as Scotney Castle (about 2.7 miles south-east) nearby, there’s older building stock in the area around Lamberhurst Quarter 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.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Take care around the mastic when scraping paint
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
- Plan mastic work ahead of painting
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
