Sand mastic in Wivelsfield Green
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. We are often asked to deal with tired mastic found when preparing windows for paint and draughty sash windows at the surround, across stone surrounds, period & listed homes and sash and case windows.
Around Wivelsfield Green, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Why act early in Wivelsfield Green
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. In a small place like Wivelsfield Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What affects the cost of sand mastic
The price is agreed before any work begins. It takes into account:
- Any working-time requirements on site
- The product the joint needs
- The number and length of the joints
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Roughly how big the job is

Advice
Wivelsfield Green homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Ockenden Manor (about 4.3 miles north-west) are a reminder that the area around Wivelsfield Green 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.
For an older house near a landmark such as Ote Hall Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Wivelsfield Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Wivelsfield station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Can I paint the new mastic?

Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
