About our sand mastic in Mill Corner
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have tired mastic found when preparing windows for paint and draughty sash windows at the surround, we can put it right, on sash and case windows, timber door frames and period & listed homes alike.
Around Mill Corner, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Every job is covered by our one-year guarantee.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What we’re called out for in Mill Corner
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic on the most exposed windows
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating
- Draughty sash windows at the surround
Managing a site like Northiam Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Before booking anyone
- Whether they’re fully insured
- When the joint can take water or movement
- Is the old sealant removed completely?

Sand mastic in Mill Corner: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Great Dixter (about 1.2 miles north) are a reminder that the area around Mill Corner has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Great Dixter, about 1.2 miles north, is one of the historic houses in the wider area around Mill Corner, and older homes nearby need a sealant that suits their walls. If you let a flat or house near Doleham station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Plan mastic work ahead of painting
- Go gently near the mastic when preparing windows
- Make sure water runs off the sill
- Check with your local planning authority if your home is listed
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours per window, depending on the condition of the joints. In a small place like Mill Corner, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Advice
Can I do it myself?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
