How we handle sand mastic in Botolph Claydon
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, applied by hand. On older homes, it suits the building far better than silicone. We work on brick reveals, stone surrounds and sash and case windows, and common reasons people get in touch are weathered mastic on the most exposed windows and gaps round a timber door in stone or brick.
Somewhere as small as Botolph Claydon, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All our work comes with a one-year guarantee.

The process
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. The work generally takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Botolph Claydon, 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.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any tricky access
- Tell us if parking is tricky

Advice
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What affects the quote in Botolph Claydon
The quote reflects the job in front of us. We take into account:
- The product the joint needs
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- How many areas need sealing
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- How we’d reach the joints
- If someone has resealed it before
- Where the property is
- Whether it’s a home or a business
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, ring 0345 464 0079 or email us.

What sand mastic looks like in Botolph Claydon
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Claydon House (about 1 mile west) are a reminder that the area around Botolph Claydon has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as East Claydon Church of England School, its window and door frames need their mastic kept sound, just like a home’s.

Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
When will the new mastic be hard?
Not straight away. The skin forms first, and the full set comes later, and we will tell you what to expect.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Should I use sand mastic or silicone?
It depends on the window. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Renew mastic before redecorating the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Crumbling stone or brickwork round the window
- Sashes that need overhauling
- Decayed frames that need repair
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
