Sand mastic for homes and businesses in Irons Bottom
Across Irons Bottom, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. Common call-outs are for failed mastic on an exposed elevation and wind and rain getting in round a sash window, across timber door frames, tenement windows and period & listed homes.
Around Irons Bottom, 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.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. Somewhere like Irons Bottom needs a little journey planning: 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.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises

What we are called out for in Irons Bottom
Water gets into small cracks in the mastic and pushes it out. Exposed elevations normally fail first.
Look out for any of the following:
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Failed mastic on an exposed elevation
- Draughty sash windows at the surround
For site and facilities teams at buildings such as Burys Court School, larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Irons Bottom
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like Irons Bottom, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Keeping the joints in good condition
Aftercare is simple:
- Make sure water runs off the sill
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
