Sand mastic in Row Town
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, tenement windows and sash and case windows, and the jobs we see most are mastic worn away on windows facing the weather and crumbling sand mastic round a window.
Around Row Town, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
You get a one-year guarantee, the same in Row Town as everywhere else we work.

Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Timber that has rotted
- Whether work needs listed building consent
- Crumbling stone or brickwork round the window

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

What sand mastic looks like in Row Town
Historic houses like Botleys Mansion (about 1.4 miles north-west) are a reminder that the area around Row Town has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you look after a building such as Holy Family Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Addlestone station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Signs you need sand mastic in Row Town
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- Gaps round a timber door in stone or brick
If you live in an older home near St Paul's, the joint between an old wall and a newer frame is normally the first place rain gets in.
Before booking anyone
- How much experience the applicator has
- Is the old sealant removed completely?
- When the joint can take water or movement
