Sand mastic for homes and businesses in Ballingdon Bottom
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on brick reveals, stone surrounds and sash and case windows, and the jobs we see most are silicone on a period window that looks wrong and mastic worn away on windows facing the weather.
In a village or hamlet like Ballingdon Bottom, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

What else we do in Ballingdon Bottom
Why deal with it now?
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. In a small place like Ballingdon Bottom, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Why Ballingdon Bottom clients choose us
- Trusted Arbo and Everbuild sealants

Your questions about sand mastic in Ballingdon Bottom
Do you cover Ballingdon Bottom for sand mastic?
Yes, Ballingdon Bottom is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Ballingdon Bottom?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Ballingdon Bottom.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How long will you be here?
Most jobs take a few hours per window, depending on the condition of the joints, including the preparation. We’ll confirm how long when we quote.

Do you need sand mastic in Ballingdon Bottom?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
Schools such as Gaddesden Row JMI School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
