Sand mastic for homes and businesses in Ovingdean
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you’re dealing with modern sealant on a period surround and mastic that needs renewing before redecorating, we can help.
Outdoor sealant needs dry, clean surfaces, so work on frames around Ovingdean is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Leave it or put it right?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Around Ovingdean, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Questions from Ovingdean
I let a flat near Moulsecoomb station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Does living near the coast affect sand mastic in Ovingdean?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Do you cover Ovingdean?
Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Ovingdean.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames usually get a flexible sealant.
How much does sand mastic cost in Ovingdean?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Quotes for sand mastic in Ovingdean
There’s no set price list. The quote depends on:
- Any working-time requirements on site
- Whether the work is at height
- The type of sealant required
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Roughly how big the job is
- Where the job is, and your postcode
- The problem you’ve noticed
- A few photos by email, if you can

How to look after the new joints
Aftercare is simple:
- Go gently near the mastic when preparing windows
- Get any rot dealt with first
- Check with your local planning authority if your home is listed
- Clear gutters so water does not pour onto the windows
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Windows and doors in Ovingdean
Ovingdean is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Moulsecoomb station? Then any sash windows need sound mastic to keep draughts and rain out. Schools such as Ovingdean Hall School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Common problems we fix in Ovingdean
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Look out for any of the following:
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Window mastic to renew ahead of painting
In the older streets around St Wulfran's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
