Sand mastic in North Halling, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you have gaps round a timber door in stone or brick and mastic that needs renewing before redecorating, we can help, whatever the surface.
Around North Halling, 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 a 12-month guarantee.

Sand mastic in North Halling: local notes
With historic houses such as Starkey Castle (about 0.6 miles east) nearby, there’s older building stock in the area around North Halling as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Michael and All Angels, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Cuxton station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Why it’s worth doing now in North Halling
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around North Halling can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Do you guarantee sand mastic work?

What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like North Halling, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

Advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
