Sand mastic in West Peckham
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We’re often asked to deal with gaps where the frame meets the masonry and crumbling sand mastic round a window, on timber door frames, sash and case windows and stone surrounds.
In a village or hamlet like West Peckham, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They decide whether consent is needed for work to your windows.
Is sand mastic better than silicone for my windows?
We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for a single window, longer for several. Somewhere as small as West Peckham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit

Sand mastic in West Peckham: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Old Soar Manor (about 1.9 miles north-west) nearby, there’s older building stock in the area around West Peckham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St Dunstan, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Mereworth Community Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
