Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
About our sand mastic in Lullington
We work across Lullington renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on sash and case windows, tenement windows and timber door frames, and the jobs we see most are failed mastic on an exposed elevation and draughts and rain around sash boxes.
Around Lullington, 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.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Sand mastic in Lullington: local notes
Lullington 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Alfriston School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St. Andrew, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
Looking after new joints is easy:
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
- Ask the planning authority about consent for listed or conservation-area homes
- Sort the mastic before the decorators arrive
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Lullington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Before we arrive
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Lullington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
