About our sand mastic in Ifieldwood
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and silicone on a period window that looks wrong, on sash and case windows, brick reveals and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Ifieldwood is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

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 dealing with it now protects both. In a small place like Ifieldwood, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.
How much does sand mastic cost in Ifieldwood?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us with a short description of the job.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Common problems we fix in Ifieldwood
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber and we normally remove them.
Keep an eye out for these signs:
- Cement or filler used on old window joints that has cracked
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
- Gaps between timber frames and stone or brick
If you let a flat or house near Ifield station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Do not paint over the new mastic
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Check with your local planning authority if your home is listed
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Frames and glazing around Ifieldwood
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like The Mill Primary Academy? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Margaret's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
