Specialist sand mastic for Heath Common: careful preparation, the right product and tidy work. Call for a quick quote.
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
- Silicone on a period window that looks wrong
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Don’t run silicone over sand mastic
- Leave the new mastic unpainted
- Plan mastic work ahead of painting
- Check the mastic when you check the paintwork
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
Sand mastic in Heath Common
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. If you are dealing with mastic worn away on windows facing the weather and mastic that needs renewing before redecorating, we can put it right, on brick reveals, stone surrounds and sash and case windows alike.
Somewhere as small as Heath Common, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Heath Common homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Parham House (about 3.1 miles west) are a reminder that the area around Heath Common has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Pulborough station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Thakeham Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Heath Common can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right 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.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
