Sand mastic in Binsted, done properly
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We’re often asked to deal with cement or filler used on old window joints that has cracked and wind and rain getting in round a sash window, across period & listed homes, timber door frames and sash and case windows.
Around Binsted, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- The product the joint needs
- The old material and how stubborn it is
- When we can work, for business premises
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
Before you ask for a quote, have a think about:
- Where the property is
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
We quote each job on its own, so the first step is telling us about yours. Simply ring 0345 464 0079 or email us and describe the job.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Planning or listed building consent (your local planning authority decides)
- Sashes that need overhauling
- Cracked or broken glass
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

Binsted homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of the Holy Cross, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Bentley (Hampshire) station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like Binsted Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Make sure water runs off the sill
- Leave the new mastic unpainted
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

FAQs for Binsted
Do you cover smaller places like Binsted?
Yes. Binsted is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Bentley (Hampshire) station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can I do it myself?
Sometimes. 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.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Why it’s worth doing now in Binsted
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around Binsted can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
