How we handle sand mastic in Horndon on the Hill
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, period & listed homes and timber door frames, and people most often call us about tired mastic found when preparing windows for paint and mastic round period door frames that has failed.
Somewhere as small as Horndon on the Hill, 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.
All of our work is guaranteed for twelve months.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like Horndon on the Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Windows and doors in Horndon on the Hill
Horndon on the Hill is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Horndon-On-the-Hill CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Get any rot dealt with first
- Check the mastic when you check the paintwork
- Avoid heavy scraping on the mastic joint
- Don’t paint over the new mastic
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Do you need sand mastic in Horndon on the Hill?
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint and we normally remove them.
Any of these means the joints need attention:
- Weathered mastic on the most exposed windows
- Gaps round a timber door in stone or brick
- Open joints round the window box
- Wind and rain getting in round a sash window
For landlords with property near Stanford-Le-Hope station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Horndon on the Hill questions

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Is sand mastic in a coastal place like Horndon on the Hill any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Do you cover Horndon on the Hill?
Yes. We work in Horndon on the Hill. For a quote, phone 0345 464 0079 or drop us an email.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
