Sand mastic for homes and businesses in Micheldever
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We work on period & listed homes, stone surrounds and timber door frames, and common reasons people get in touch are draughts and rain around sash boxes and old sand mastic that has cracked, crumbled or fallen out.
Around Micheldever, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. In a small place like Micheldever, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
- Do not paint over the new mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.

Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.

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.
