Sand mastic for homes and businesses in East Hampnett
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, tenement windows and brick reveals, and common reasons people get in touch are draughts and rain around sash boxes and silicone on a period window that looks wrong.
Homes in small places like East Hampnett often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

Signs you need sand mastic in East Hampnett
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they usually need raking out.
People normally contact us when they notice something like this:
- Crumbling sand mastic round a window
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
- A silicone bead on a sash window that spoils the look
In the older streets around The Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Advice
East Hampnett homes and the weather
Historic houses like Goodwood House (about 2.4 miles north-west) are a reminder that the area around East Hampnett 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. 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.

Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What 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 finished to sit neatly against the masonry.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will talk you through it.
How much does sand mastic cost in East Hampnett?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Keeping the joints in good condition
Aftercare is simple:
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
- Avoid patching sand mastic with silicone
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

- Masonry that needs repairing
- Putty and glazing repairs

Why it’s worth doing now in East Hampnett
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like East Hampnett, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.
