Sand mastic in Icklesham, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have tired mastic found when preparing windows for paint and silicone on a period window that looks wrong, we can help.
Around Icklesham, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

The process
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere like Icklesham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Mention any tricky access
- Mention if the joints have been sealed before
- Tell us if parking is tricky

Advice
Surface by surface
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Why act early in Icklesham
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Around Icklesham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot 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, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What sand mastic looks like in Icklesham
Icklesham 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. Historic houses like Lamb House (about 3.7 miles north-east) are a reminder that the area around Icklesham has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Winchelsea station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as The Parish Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Icklesham is about 6 miles north-east of Hastings, in East Sussex. Across the TN36 area, our applicators can take on sand mastic. We cover 289 towns and villages across East Sussex, large and small. There’s also a page for Brighton, about 35 miles away.

Near you in Icklesham

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure water runs off the sill
- Do not paint over the new mastic
- Renew mastic before redecorating the windows
- Look over the window mastic once a year
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Common problems we fix in Icklesham
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating
- Gaps round a timber door in stone or brick
- Mastic worn away on windows facing the weather
For site and facilities teams at buildings such as Icklesham Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Icklesham: your questions answered
Does living near the coast affect sand mastic in Icklesham?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
I let a flat near Winchelsea station. Can you help?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Do you work in Icklesham?
Yes. We work in Icklesham. For a quote, ring 0345 464 0079 or email us.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Should I use sand mastic or silicone?
We’ll help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
