About our sand mastic in Ruscote
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on stone surrounds, period & listed homes and brick reveals, and common reasons people get in touch are failed mastic on an exposed elevation and cracked mastic round a front door frame.
Around Ruscote, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
We stand behind the work with a one-year guarantee.

What we’re called out for in Ruscote
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
Most people get in touch after spotting one of these:
- Mastic round period door frames that has failed
- Crumbling sand mastic round a window
- Modern sealant on a period surround
- Draughts and rain around sash boxes
In the older streets around St Paul's Church Centre, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Make sure water runs off the sill
- Don’t paint over the new mastic
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Advice
Landlord and commercial work in Ruscote
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Ruscote homes and the weather
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. Historic houses like Broughton Castle (about 1.8 miles south-west) are a reminder that the area around Ruscote 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’s traditional sand mastic.
For landlords with property near Banbury station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like St Joseph's Catholic Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
