How we handle sand mastic in Sandwich Bay Estate
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Typical jobs include a silicone bead on a sash window that spoils the look and window mastic to renew ahead of painting, on sash and case windows, tenement windows and brick reveals.
Somewhere as small as Sandwich Bay Estate, 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.
Every job comes with a 12-month guarantee.

How the job changes by surface
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
When to call us in Sandwich Bay Estate
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Signs it’s time to call us include:
- Tired mastic found when preparing windows for paint
- Mastic worn away on windows facing the weather
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
Walmer Castle, about 4.6 miles south, is one of the historic houses in the wider area around Sandwich Bay Estate.

Sandwich Bay Estate questions
Can you help a landlord with a rental near Sandwich station?
Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Sandwich Bay Estate?
Yes, Sandwich Bay Estate is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Are you fully insured?
Yes. We are fully insured.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before work begins.
What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In a small place like Sandwich Bay Estate, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Sand mastic in Sandwich Bay Estate: local notes
Sandwich Bay Estate is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Walmer Castle (about 4.6 miles south) nearby, there’s older building stock in the area around Sandwich Bay Estate as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Sandwich station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Sir Roger Manwood's School, the mastic around its windows and doors needs looking after like any other building’s.
