How we handle sand mastic in Horney Common
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on period & listed homes, brick reveals and stone surrounds, and the jobs we see most are cement or filler used on old window joints that has cracked and tired mastic found when preparing windows for paint.
In a village or hamlet like Horney Common, 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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How we quote for sand mastic
There’s no set price list. What we look at:
- The product the joint needs
- The old material and how stubborn it is
- The number and length of the joints
- When we can work, for business premises
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- If someone has resealed it before
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or drop us an email.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Inspect the joints round the windows every year or so
- Go gently near the mastic when preparing windows
- Don’t paint over the new mastic
- Ask the planning authority about consent for listed or conservation-area homes
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Will you come out to Horney Common?

What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
When will the new mastic be hard?

Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
How do I get a quote for sand mastic in Horney Common?

Signs you need sand mastic in Horney Common
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
These are the problems we are asked about most:
- Gaps round a timber door in stone or brick
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
If you live in an older home near Christ Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job generally takes a few hours for a single window, longer for several, and we explain the cure time before we leave.

- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
