Sand mastic in Greenstead Green, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have draughts and rain around sash boxes and cement or filler used on old window joints that has cracked, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Greenstead Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

What happens if it’s left?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Around Greenstead Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Don’t paint over the new mastic
- Avoid patching sand mastic with silicone
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Windows and doors in Greenstead Green
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Chappel & Wakes Colne station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as The Ramsey Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Common problems we fix in Greenstead Green
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Keep an eye out for these signs:
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Open joints round the window box
If you live in an older home near Parish Church of St James, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
FAQs for Greenstead Green
Do you cover Greenstead Green for sand mastic?
Yes. We work across London and the South East, and Greenstead Green is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Will you come out to Greenstead Green?
Yes, Greenstead Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Should I use sand mastic or silicone?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
