Sand mastic for sash & case windows in East End, Hampshire
Our applicators work in East End on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. In a small place like East End, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Advice
About our sand mastic in East End
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. We work on stone surrounds, timber door frames and sash and case windows, and the jobs we see most are gaps between timber frames and stone or brick and window mastic to renew ahead of painting.
Homes in small places like East End often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What happens if it’s left?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Older cottages and farmhouses around East End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

What sand mastic looks like in East End
East End is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Beaulieu Palace House (about 3.5 miles north-east) are a reminder that the area around East End has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Lymington Pier station, any sash windows need sound mastic to keep draughts and rain out. Schools such as South Baddesley Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.

Looking after it afterwards
Aftercare is simple:
- Inspect the joints round the windows every year or so
- Find out about consent before window work on a listed home
- Plan mastic work ahead of painting
- Clear gutters so water doesn’t pour onto the windows
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
