Questions from Rye Foreign
I let a flat near Rye station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover Rye Foreign for sand mastic?
Yes. Our work covers London and the South East, and Rye Foreign is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Sand mastic in Rye Foreign
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We are often asked to deal with old cement repairs round a window that have failed and gaps between timber frames and stone or brick, across sash and case windows, period & listed homes and timber door frames.
Homes in small places like Rye Foreign often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by a one-year guarantee, wherever you are in East Sussex.

Rye Foreign homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Lamb House (about 1.9 miles south-east) are a reminder that the area around Rye Foreign 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.
In the older streets around The Parish Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Peasmarsh Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Quotes for sand mastic in Rye Foreign
Your quote is based on your job. We take into account:
- Any mould that needs treating
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- Access and height
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What to tell us for a quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- What’s wrong with the joints now

What we’re called out for in Rye Foreign
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Common reasons people contact us are:
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic worn away on windows facing the weather
- Open joints round the window box
If you let a flat or house near Rye station, any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- How the colour is chosen
- How long the guarantee is
- How much experience the applicator has
- Which sealant they’ll use, and why
What happens if it’s left?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Rye Foreign can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost 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, so you know where you stand.
Why us?
- An ARBOMaster approved applicator
- Arbo and Everbuild products

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Damaged stone surrounds
- Whether work needs listed building consent
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Tenement windows
- Brick reveals
- Sash and case windows
- Period & listed homes
- Timber door frames
- Stone surrounds
What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere as small as Rye Foreign, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
