Sand mastic for homes and businesses in Lanham Green
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We are often asked to deal with old cement repairs round a window that have failed and gaps between timber frames and stone or brick, across sash and case windows, tenement windows and timber door frames.
Somewhere as small as Lanham Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Lanham Green homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Cressing station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Cressing Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours per window, depending on the condition of the joints. In a small place like Lanham Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Move anything stored near the joints

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
- Get any rot dealt with first
- Renew mastic before redecorating the windows
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Signs you need sand mastic in Lanham Green
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint and we normally remove them.
The problems people generally mention when they call are:
- Gaps between timber frames and stone or brick
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
- Draughts and rain around sash boxes
For an older house near a landmark such as Parish Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Who turns up on the day
- When the joint can take water or movement
- How the colour is chosen
- The length of the guarantee
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Timber that has rotted

Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.
