Sand mastic in Chilham, done properly
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on brick reveals, sash and case windows and period & listed homes, and common reasons people get in touch are cement or filler used on old window joints that has cracked and modern sealant on a period surround.
Homes in small places like Chilham 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.
All our work comes with a one-year guarantee, wherever you are in Kent.

What sand mastic looks like in Chilham
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Chilham station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Why it’s worth doing now in Chilham
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Around Chilham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Questions from Chilham
Do you work for landlords with property near Chilham station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is Chilham in your area for sand mastic?
Yes, Chilham is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Is it possible to take out silicone and use sand mastic instead?
Normally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can you quote for more than one area?
Yes. Just list everything you need.
How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a single window, longer for several from start to finish. Somewhere like Chilham needs a little journey planning: 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.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- 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.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Let us know about earlier repairs to the joints

Advice
Can I do it myself?
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 doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How the job changes by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Leave the new mastic unpainted
- Clear gutters so water doesn’t pour onto the windows
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
