Window mastic in Shipton-under-Wychwood, done properly
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Common call-outs are for gaps where the sill meets the wall and mastic that has split away from the wall, on window sills, aluminium frames and uPVC windows.
Around Shipton-under-Wychwood, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you’re covered after we have gone.

What window mastic looks like in Shipton-under-Wychwood
Historic houses like Minster Lovell Hall (about 5 miles south-east) are a reminder that the area around Shipton-under-Wychwood 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Wychwood Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Shipton station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Clear any debris from frame drain holes
- Keep paint and stain on wooden frames in good order
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

Advice
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Common questions in Shipton-under-Wychwood
Can you help a landlord with a rental near Shipton station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Shipton-under-Wychwood?
Yes, Shipton-under-Wychwood is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before we start.
Why act early in Shipton-under-Wychwood
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a small place like Shipton-under-Wychwood, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
