Sand mastic for sash & case windows in Hunton, Kent
Our applicators work in Hunton on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- Window mastic to renew ahead of painting
Why deal with it now?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Hunton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

About our sand mastic in Hunton
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 period homes, it looks right where silicone wouldn’t. If you have mastic dropping out of the joint and modern sealant on a period surround, we can help, whatever the surface.
Somewhere as small as Hunton, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Windows and doors in Hunton
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Hunton Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Mary's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

- Whether there’s mould to deal with
- The number and length of the joints
- How many areas need sealing

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. Somewhere as small as Hunton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
