About our sand mastic in Black Notley
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you have mastic worn away on windows facing the weather and mastic that needs renewing before redecorating, we can put it right, whatever the surface.
Somewhere as small as Black Notley, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Signs you need sand mastic in Black Notley
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Signs it’s time to call us include:
- Gaps between timber frames and stone or brick
- Draughty sash windows at the surround
- Window mastic to renew ahead of painting
- Modern sealant on a period surround
For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- Which colour the sealant will be
- Is VAT in the price?
- How hidden problems are handled
- When the joint can take water or movement
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours for a single window, longer for several, depending on the size of the job.
