Sand mastic in Hare Street
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. Typical jobs include mastic that needs renewing before redecorating and mastic worn away on windows facing the weather, on timber door frames, tenement windows and stone surrounds.
In a village or hamlet like Hare Street, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What sand mastic looks like in Hare Street
Historic houses like Hill Hall (about 3 miles west) are a reminder that the area around Hare Street has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Hare Street, as everywhere, sand mastic is only as good as the preparation behind it.

What happens on the day
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before work begins. The work usually takes anything from a few hours to a full day, depending on how many windows. In a small place like Hare Street, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.

Advice
What affects the cost of sand mastic
You will get a clear quote before work begins. It takes into account:
- Mould in or behind the old joints
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
When you call or email, it’s useful to know:
- Where the property is
- If someone has resealed it before
- Whether it’s a home or a business
- Pictures of the joints, sent by email
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, phone 0345 464 0079 or email us.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the job changes by surface
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
When it is not the sealant
A few problems are outside what sealant work can do:
- Masonry that needs repairing
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Stone surrounds

- Period & listed homes
Common problems we fix in Hare Street
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Most people get in touch when they notice something like this:
- Silicone on a period window that looks wrong
- Mastic round period door frames that has failed
- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
If you live in an older home near Church of St Margaret of Antioch, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

FAQs for Hare Street
Is there a guarantee on sand mastic in Hare Street?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Hare Street within the area you cover?
Yes. Hare Street 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.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They decide whether consent is needed.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Do not paint over the new mastic
- Clear gutters so water doesn’t pour onto the windows
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
