Sand mastic for homes and businesses in Littlehampton
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We work on stone surrounds, sash and case windows and timber door frames, and the jobs we see most are tired mastic found when preparing windows for paint and mastic round period door frames that has failed.
In a town like Littlehampton, older houses sit alongside newer estates, with windows of every age. All of them depend on a sound bead of mastic between frame and wall.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What sand mastic looks like in Littlehampton
Littlehampton 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near The Parish Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Littlehampton station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as The Littlehampton Academy, larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in Littlehampton
Littlehampton questions
Does living near the coast affect sand mastic in Littlehampton?
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.
Do you cover Littlehampton for sand mastic?
Yes, Littlehampton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Are you fully insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Can landlords and businesses book you?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before we start.
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.

The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a single window, longer for several from start to finish. In Littlehampton, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

How we quote for sand mastic
Every job gets its own quote. These are the things that affect it:
- Access and height
- The product the joint needs
- The number and length of the joints
- How many rooms, windows or areas are involved
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
What to tell us when you ask for a quote:
- The type of property
- The rough size of the job
- How we’d reach the joints
- Photos by email, if that is easy
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work.
Aftercare tips
To keep the joints looking good and working properly:
- Have rotten timber repaired before new mastic goes in
- Don’t run silicone over sand mastic
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

We also work for property managers and facilities teams in Littlehampton and across West Sussex. We can quote a run of properties together, and we’re fully insured for the work.

What the job involves on each surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Crumbling stone or brickwork round the window
- Cracked or broken glass
- Timber that has rotted
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
