Advice
Sand mastic in Kingston near Lewes, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. If you are dealing with silicone on a period window that looks wrong and patchy fillers round a sash window, we can help, on brick reveals, timber door frames and sash and case windows alike.
Homes in small places like Kingston near Lewes 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.
Each job carries a 12-month guarantee, whatever its size.

Frames and glazing around Kingston near Lewes
Historic houses like Anne of Cleves House (about 1.5 miles north-east) are a reminder that the area around Kingston near Lewes has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
In the older streets around St Pancras Church (Kingston near Lewes), replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Iford and Kingston Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Questions from Kingston near Lewes
Can you do sand mastic in Kingston near Lewes?
Yes, Kingston near Lewes is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Kingston near Lewes?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Different surfaces, different methods
