How we handle sand mastic in Pevensey Bay
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. We work on stone surrounds, sash and case windows and brick reveals, and the jobs we see most are open joints round the window box and old cement repairs round a window that have failed.
In smaller places like Pevensey Bay, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Every job is covered by a 12-month guarantee.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Windows and doors in Pevensey Bay
Pevensey Bay is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
Letting a property close to Pevensey Bay station? Then any sash windows need sound mastic to keep draughts and rain out. Schools such as Pevensey and Westham CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

When to call us in Pevensey Bay
Timber frames move with the seasons. That movement opens up the mastic joint over time.
Any of these means the joints need attention:
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
- Cracked mastic round a front door frame
Homes close to St Wilfrid's Church Pevensey Bay include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Pevensey Bay: your questions answered
Is sand mastic in a coastal place like Pevensey Bay any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Pevensey Bay station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it possible to take out silicone and use sand mastic instead?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
How do I get a quote for sand mastic in Pevensey Bay?
Size, access and the old material all affect the cost. Call for a quick quote.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What happens if it’s left?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Around Pevensey Bay, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

How to look after the new joints
To keep the joints looking good and working properly:
- Keep sills and gutters clear so water drains away
- Avoid heavy scraping on the mastic joint
- Sort the mastic before the decorators arrive
- Do not paint over the new mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
