Sand Mastic in Charter Alley
Specialist sand mastic for Charter Alley: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- Window mastic to renew ahead of painting
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sand mastic for homes and businesses in Charter Alley
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. Typical jobs include window mastic to renew ahead of painting and cement or filler used on old window joints that has cracked, on timber door frames, sash and case windows and stone surrounds.
Outdoor sealant needs dry, clean surfaces, so work on frames around Charter Alley is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes with the work, just as it does everywhere we cover.

When to call us in Charter Alley
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
The most common problems we see are:
- Patchy fillers round a sash window
- Window mastic to renew ahead of painting
- Old sand mastic that has cracked, crumbled or fallen out
- Cracked mastic round a front door frame
In the older streets around Christ Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about sand mastic in Charter Alley
Can you do sand mastic in Charter Alley?
Yes. Our work covers London and the South East, and Charter Alley is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
I let a flat near Bramley (Hants) station. Can you help?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Aftercare tips
So the new joints stay in good condition:
- Ask a joiner to look at soft timber first
- Make sure water runs off the sill
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Sand mastic in Charter Alley: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like The Vyne (about 2.6 miles east) are a reminder that the area around Charter Alley 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’s traditional sand mastic.
Rented homes near Bramley (Hants) station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Schools such as The Priory Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
