How we handle window mastic in Middle Claydon
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We are often asked to deal with hard, cracked sealant around windows and mastic that’s falling out in pieces, across timber windows & doors, uPVC windows and window sills.
Around Middle Claydon, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

How it works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job generally takes a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. Somewhere like Middle Claydon needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, 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.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.

What happens if it’s left?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Middle Claydon, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Frames and glazing around Middle Claydon
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Claydon House (about 0.3 miles south) are a reminder that the area around Middle Claydon has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as East Claydon Church of England School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
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. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Paint up to the joint, not over it
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
- Ventilate rooms so frames don’t stay wet inside
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
Look out for the warning signs: 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.
