Window mastic in Kiddington, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, uPVC windows and patio & French doors, and the jobs we see most are water coming in at the bottom corners of a door and leaking joints at the ends of sills.
Mastic can only go onto a dry, clean joint, so window work in Kiddington is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, it’s backed by our 12-month guarantee in Kiddington and across Oxfordshire.

Why it’s worth doing now in Kiddington
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Kiddington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

How the job changes by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Questions from Kiddington
Do you work for landlords with property near Charlbury station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover Kiddington for window mastic?
Yes. Our work covers London and the South East, and Kiddington is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
How do I get a quote for window mastic in Kiddington?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
How many windows can you do in a day?
A few frames take a few hours, while a whole house takes longer. You’ll get a timescale with the quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Clean frames with a soft cloth and soapy water
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
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. If you notice one, it’s time to get the joint looked at.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Advice
Frames and glazing around Kiddington
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Blenheim Palace (about 4.6 miles south) are a reminder that the area around Kiddington 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.
If you live in an older home near Church of St Nicholas, the joint between an old wall and a newer frame is usually the first place rain gets in. Rented homes near Charlbury station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
