Windows and doors in Wimbish Green
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Horham Hall (about 3.8 miles south) are a reminder that the area around Wimbish Green 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.
If you look after a building such as Wimbish Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Newport (Essex) station? Then any sash windows need sound mastic to keep draughts and rain out. Homes close to St Paul's Mission Room include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic in Wimbish Green, done properly
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on tenement windows, period & listed homes and sash and case windows, and the jobs we see most are failed mastic on an exposed elevation and crumbling sand mastic round a window.
Around Wimbish Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Period and listed homes
A traditional finish suits a period property.
Aftercare tips
So the new joints stay in good condition:
- Do not run silicone over sand mastic
- Renew mastic before redecorating the windows
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Somewhere like Wimbish Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about parking restrictions
- Mention any tricky access

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
