What sand mastic looks like in Burdrop
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Broughton Castle (about 3.8 miles east) are a reminder that the area around Burdrop 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.
If you look after a building such as Sibford Gower Endowed 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 Church of Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

About our sand mastic in Burdrop
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you have cement or filler used on old window joints that has cracked and crumbling sand mastic round a window, we can help, whatever the surface.
In a village or hamlet like Burdrop, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All our work comes with a one-year guarantee.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Inspect the joints round the windows every year or so
- Don’t paint over the new mastic
- Clear gutters so water doesn’t pour onto the windows
- Go gently near the mastic when preparing windows
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
What the job involves on each surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. Somewhere like Burdrop needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Move anything stored near the joints
- Let us know about parking restrictions
- Mention any tricky access

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
- Damaged stone surrounds
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.

Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
