The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a single window, longer for several. In a small place like Milton-under-Wychwood, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit

- Let us know if you’ve seen damp or leaks

Advice
Sand mastic for homes and businesses in Milton-under-Wychwood
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. If you have gaps between timber frames and stone or brick and old sand mastic that has cracked, crumbled or fallen out, we can put it right, on brick reveals, stone surrounds and period & listed homes alike.
Homes in small places like Milton-under-Wychwood 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.
Big or small, it’s backed by our one-year guarantee.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What affects the cost of sand mastic
Your quote is based on your job. We take into account:
- How easy the joints are to reach
- How many areas need sealing
- How much there is to do
- How much old sealant there is and how hard it is to remove
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Frames and glazing around Milton-under-Wychwood
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Wychwood Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Shipton station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as Church of St Simon and St Jude, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Looking after it afterwards
So the new joints stay in good condition:
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Get any rot dealt with first
- Find out about consent before window work on a listed home
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Why act early in Milton-under-Wychwood
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Milton-under-Wychwood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Can you replace silicone on a period window with sand mastic?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
How do I get a quote for sand mastic in Milton-under-Wychwood?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How long does sand mastic take to harden?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
