About our sand mastic in Kelvedon Hatch
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Common call-outs are for cement or filler used on old window joints that has cracked and mastic that needs renewing before redecorating, on tenement windows, timber door frames and sash and case windows.
In a village or hamlet like Kelvedon Hatch, 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.
Each job carries a 12-month guarantee, whatever its size.

Should I try it myself first?
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.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Decayed frames that need repair
- Decisions on consent for listed homes
- Sashes that need overhauling

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Find out about consent before window work on a listed home
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do.

- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.

What sand mastic looks like in Kelvedon Hatch
Historic houses like Ingatestone Hall (about 5 miles east) are a reminder that the area around Kelvedon Hatch has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Shenfield station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to New Church of St Nicholas include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Kelvedon Hatch Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.
