Sand mastic for sash & case windows in Apuldram, West Sussex
Our applicators work in Apuldram on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
- Open joints round the window box
Why act early in Apuldram
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Apuldram, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

About our sand mastic in Apuldram
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. Typical jobs include gaps round a timber door in stone or brick and mastic dropping out of the joint, on stone surrounds, brick reveals and sash and case windows.
Somewhere as small as Apuldram, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard.

Frames and glazing around Apuldram
Apuldram is within about 3 miles of 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Chichester station change hands often, and 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 Mary, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as Fishbourne CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The process
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a few hours per window, depending on the condition of the joints. Somewhere like Apuldram needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the surrounds with you and agree the joints to renew.
- 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.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

FAQs for Apuldram
Is sand mastic in a coastal place like Apuldram any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Apuldram?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Plan mastic work ahead of painting
- Make sure water runs off the sill
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Sashes that rattle, stick or won’t open
- Decayed frames that need repair
- Masonry that needs repairing
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
