Sand mastic in East Clandon
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 older homes, it suits the building far better than silicone. If you have crumbling sand mastic round a window and weathered mastic on the most exposed windows, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around East Clandon is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
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.

What sand mastic looks like in East Clandon
Historic houses like Hatchlands Park (about 0.5 miles north-east) are a reminder that the area around East Clandon 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 is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Clandon CofE Aided Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Clandon station, any sash windows need sound mastic to keep draughts and rain out.

Yes, East Clandon is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
I let a flat near Clandon station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
When to call us in East Clandon
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
The problems people usually mention when they call are:
- Window mastic to renew ahead of painting
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
- Mastic dropping out of the joint
For an older house near a landmark such as Church of St Thomas of Canterbury, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Whether they seal over old material or remove it
- What product goes in the joint
- What the cure time is
- Whether they’re fully insured
Why deal with it now?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Where a wall is exposed, as many are in small places like East Clandon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

The process
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like East Clandon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Related advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Take care around the mastic when scraping paint
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
- Inspect the joints round the windows every year or so
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Whether work needs listed building consent
- Crumbling stone or brickwork round the window
- Sashes that rattle, stick or will not open
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.
