About our sand mastic in Allhallows-on-Sea
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead and we’ll explain which is best for yours. If you’re dealing with mastic worn away on windows facing the weather and mastic dropping out of the joint, we can help, whatever the surface.
Somewhere as small as Allhallows-on-Sea, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, in Allhallows-on-Sea and everywhere else we cover.

Allhallows-on-Sea homes and the weather
Allhallows-on-Sea is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Chalkwell station, any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Allhallows Primary Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

Questions from Allhallows-on-Sea
Will you come out to Allhallows-on-Sea?
Yes. Allhallows-on-Sea is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is sand mastic in a coastal place like Allhallows-on-Sea any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Why act early in Allhallows-on-Sea
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Allhallows-on-Sea, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Keeping the joints in good condition
Looking after new joints is easy:
- Make sure water runs off the sill
- Take care around the mastic when scraping paint
- Ask the planning authority about consent for listed or conservation-area homes
- Sort the mastic before the decorators arrive
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
