How we handle sand mastic in West Wittering
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have cement or filler used on old window joints that has cracked and tired mastic found when preparing windows for paint, we can help, on brick reveals, tenement windows and stone surrounds alike.
In a village or hamlet like West Wittering, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

FAQs for West Wittering
I let a flat near Nutbourne station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Is West Wittering within the area you cover?
Yes. West Wittering is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
How long does sand mastic take?
A typical job takes anything from a few hours to a full day, depending on how many windows, including the preparation. Your quote will say how long we expect yours to take.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
Quotes for sand mastic in West Wittering
The quote reflects the job in front of us. We take into account:
- Any mould that needs treating
- Any working-time requirements on site
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Whether it has been sealed before
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
- Keep modern sealant off the mastic
- Make sure water runs off the sill
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

What sand mastic looks like in West Wittering
West Wittering 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Nutbourne station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as West Wittering Parochial Church of England School, the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in West Wittering
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Around West Wittering, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.

When to call us in West Wittering
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they normally need raking out.
Most people get in touch after spotting one of these:
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
- Failed mastic on an exposed elevation
- Draughts and rain around sash boxes
Homes close to The Parish Church of St Peter and St Paul include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
