The process
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a single window, longer for several. Somewhere as small as Bletchingdon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Advice
About our sand mastic in Bletchingdon
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you have silicone on a period window that looks wrong and gaps where the frame meets the masonry, we can put it right, whatever the surface.
In a village or hamlet like Bletchingdon, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Windows and doors in Bletchingdon
Historic houses like Blenheim Palace (about 3.9 miles west) are a reminder that the area around Bletchingdon 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. 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.
For landlords with property near Tackley station, any sash windows need sound mastic to keep draughts and rain out. Schools such as Bletchingdon Parochial Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St Giles include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What affects the quote in Bletchingdon
We quote each job individually. This is what makes a difference:
- Whether there’s mould to deal with
- The product the joint needs
- Access and height
- When we can work, for business premises
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- How we’d reach the joints
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
Why it’s worth doing now in Bletchingdon
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 Bletchingdon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.
