Sand mastic in Ladwell, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have gaps round a timber door in stone or brick and crumbling sand mastic round a window, we can put it right.
In a village or hamlet like Ladwell, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In a small place like Ladwell, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep sills and gutters clear so water drains away
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
- Take care around the mastic when scraping paint
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that need overhauling
- Decisions on consent for listed homes
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

Sand mastic in Ladwell: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Chandlers Ford station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like John Keble Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours for a single window, longer for several, depending on the amount of work. Somewhere like Ladwell 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.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
