Sand mastic in Roedean, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include window mastic to renew ahead of painting and mastic round period door frames that has failed, across period & listed homes, sash and case windows and timber door frames.
Somewhere as small as Roedean, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
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 it’s worth doing now in Roedean
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Roedean, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why choose Mr Mastic in Roedean
- Neat joints and a tidy finish
- Approved under the ARBOMaster scheme

The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Roedean, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Common problems we fix in Roedean
Timber frames move with the seasons. That movement opens up the mastic joint over time.
Signs it’s time to call us include:
- Open joints round the window box
- Crumbling sand mastic round a window
- Tired mastic found when preparing windows for paint
- Draughts and rain around sash boxes
For an older house near a landmark such as St Mark's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Windows and doors in Roedean
Roedean is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Brighton station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like St Mark's CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
