About our sand mastic in Adur
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you have draughts and rain around sash boxes and patchy fillers round a sash window, we can help, on brick reveals, period & listed homes and timber door frames alike.
Homes in small places like Adur often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, you get the same 12-month guarantee in Adur and across West Sussex.

How the job changes by surface
Stone surrounds
Old stone surrounds are often uneven, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Landlords, agents and businesses in Adur
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
When to call us in Adur
Timber frames move with the seasons. That movement opens up the mastic joint over time.
The problems people normally mention when they call include:
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
- Crumbling sand mastic round a window
- Gaps where the frame meets the masonry
If you look after a building such as The Sir Robert Woodard Academy, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include

What else we do in Adur
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
FAQs for Adur
Does living near the coast affect sand mastic in Adur?
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.
I let a flat near Shoreham-By-Sea station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Adur homes and the weather
Adur 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 Portslade Manor (about 3.2 miles east) nearby, there’s older building stock in the area around Adur 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.
Rented homes near Shoreham-By-Sea station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as St Nicolas' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Do not paint over the new mastic
- Look over the window mastic once a year
- Take care around the mastic when scraping paint
- Have rotten timber repaired before new mastic goes in
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Adur, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
