Jury's Gap Sand Mastic
We cover Jury's Gap for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- Cement or filler used on old window joints that has cracked
What the job involves on each surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Stone surrounds
The stone is treated with care while raking out the old mastic.
Sand mastic in Jury's Gap
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and cracked mastic round a front door frame, we can help, on tenement windows, sash and case windows and timber door frames alike.
In a village or hamlet like Jury's Gap, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Windows and doors in Jury's Gap
Jury's Gap is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Lamb House (about 4.4 miles west) are a reminder that the area around Jury's Gap has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Around Jury's Gap, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look over the window mastic once a year
- Don’t run silicone over sand mastic
- Go gently near the mastic when preparing windows
- Get any rot dealt with first
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Common problems we fix in Jury's Gap
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
The most common problems we see are:
- Patchy fillers round a sash window
- Silicone on a period window that looks wrong
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
If you let a flat or house near Rye station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Jury's Gap: your questions answered
Can you help a landlord with a rental near Rye station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Does the coastal weather in Jury's Gap affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer.

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up.

DIY versus a professional finish
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
