What sand mastic looks like in East Worthing
East Worthing is close to 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around St George's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near East Worthing station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Lyndhurst Infant School? Then the mastic around its windows and doors needs looking after like any other building’s.

Sand mastic in East Worthing, done properly
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We’re often asked to deal with old cement repairs round a window that have failed and draughts and rain around sash boxes, across period & listed homes, stone surrounds and timber door frames.
Houses in smaller places like East Worthing can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.

What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a smaller place like East Worthing, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Surface by surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Avoid patching sand mastic with silicone
- Get any rot dealt with first
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
East Worthing questions
Do you cover smaller places like East Worthing?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near East Worthing station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
How much does sand mastic cost in East Worthing?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

What affects the quote in East Worthing
Every job gets its own quote. This is what makes a difference:
- The type of sealant required
- Any mould that needs treating
- The number and length of the joints
- How many areas need sealing
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
To make quoting easier, let us know:
- The problem you’ve noticed
- The address or postcode of the job
- The rough size of the job
