Sand mastic for homes and businesses in Gambles Green
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with mastic that needs renewing before redecorating and mastic round period door frames that has failed, across period & listed homes, tenement windows and stone surrounds.
Outdoor sealant needs dry, clean surfaces, so work on frames around Gambles Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by our one-year guarantee.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Gambles Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we’ll talk you through it.

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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Gambles Green homes and 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 Terling Church of England Voluntary Aided Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near United Reformed Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will talk you through it.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Which products do you use?

How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
