Sand mastic for sash & case windows in Bumble's Green, Essex
Problem with your window and door surrounds in Bumble's Green? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
- Draughty sash windows at the surround
How we handle sand mastic in Bumble's Green
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and old cement repairs round a window that have failed, we can put it right.
In a village or hamlet like Bumble's Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, 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.

Landlord and commercial work in Bumble's Green
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
When it is not the sealant
A few problems are outside what sealant work can do:
- Sash cords, weights and draught-proofing of the sashes
- Damaged stone surrounds
- Whether work needs listed building consent

Surface by surface
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Bumble's Green questions
Do you work for landlords with property near Broxbourne station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Bumble's Green in your area for sand mastic?
Yes, Bumble's Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we’ll advise.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Common problems we fix in Bumble's Green
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Look out for these signs:
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
- Weathered mastic on the most exposed windows
- Draughts and rain around sash boxes
If you let a flat or house near Broxbourne station, older sash windows in a rental need their mastic kept sound to keep the weather out.
