What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Eel Pie Island, the repair is bigger than a sealant job.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- Neat joints and a tidy finish

Sand mastic for homes and businesses in Eel Pie Island
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you have draughts and rain around sash boxes and weathered mastic on the most exposed windows, we can help, whatever the surface.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

It normally takes a few hours for a single window, longer for several.

- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.

What sand mastic looks like in Eel Pie Island
With historic houses such as Richmond House (about 0.2 miles west) nearby, there’s older building stock in the area around Eel Pie Island as well as newer homes. 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Eel Pie Island can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Schools such as St Mary's Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
When to call us in Eel Pie Island
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Any of these means the joints need attention:
- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
- Draughty sash windows at the surround
- Crumbling sand mastic round a window
For an older house near a landmark such as St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before booking anyone

- When the joint can take water or movement
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
