Window mastic for Shipton-on-Cherwell and the surrounding area: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.

- Sealant in the wrong colour for the frame
Window mastic in Shipton-on-Cherwell
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you have black, perished sealant on frames and sealant in the wrong colour for the frame, we can help, whatever the surface.
Around Shipton-on-Cherwell, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we’re called out for in Shipton-on-Cherwell
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Keep an eye out for any of the following:
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
Managing a site like The Marlborough Church of England School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Before you book anyone
- What product goes in the joint
- Whether they seal over old material or remove it
- What guarantee comes with the work
- Are they insured?
What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- uPVC windows
- Aluminium frames
- Composite doors
- Patio & French doors
- Window sills
- Timber windows & doors

How to look after the new joints
To keep the joints looking good and working properly:
- Do not use solvent cleaners on the joint
- Keep jet washers away from the mastic
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
Silicone can’t normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
uPVC windows

What window mastic looks like in Shipton-on-Cherwell
Historic houses like Blenheim Palace (about 2.5 miles west) are a reminder that the area around Shipton-on-Cherwell 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Tackley station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of Holy Cross, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
