Sand mastic in Easebourne
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. If you have old sand mastic that has cracked, crumbled or fallen out and a silicone bead on a sash window that spoils the look, we can help.
Mastic can only go onto a dry, clean joint, so window work in Easebourne is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, you get the same one-year guarantee in Easebourne and across West Sussex.

Easebourne homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Cowdray House (about 0.6 miles south) are a reminder that the area around Easebourne 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 is traditional sand mastic.
Managing a site like Easebourne CofE Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near The Parish Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Easebourne
Is sand mastic in Easebourne guaranteed?
All our work, in Easebourne and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Will you come out to Easebourne?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Do you have insurance?
Yes. Full insurance covers our work.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Easebourne.
Why it’s worth doing now in Easebourne
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. In a small place like Easebourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us
- 20+ years of sealant experience
- ARBOMaster approved applicator
- 12-month guarantee on every job
- We leave the area clean and tidy
What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Easebourne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Have rotten timber repaired before new mastic goes in
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
- Clear gutters so water does not pour onto the windows
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
