Window mastic in Kingham, done properly
Some gaps around frames are far deeper than they look. 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. Common call-outs are for a bead that doesn’t match the frame and cold air getting in at the frame edge, across aluminium frames, patio & French doors and timber windows & doors.
In a village or hamlet like Kingham, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months.

Advice
DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Why act early in Kingham
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we will say so. Where a wall is exposed, as many are in small places like Kingham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Frames and glazing around Kingham
With historic houses such as Chastleton House (about 3.3 miles north) nearby, there’s older building stock in the area around Kingham as well as newer homes. In older buildings, 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.
For landlords with property near Kingham station, renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Kingham Primary 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 St Andrew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Paint up to the joint, not over it
- Use gentle cleaners on frames and sealant
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.

Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Can you do upstairs windows?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
When is the sealant fully cured?

Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is there any odour?
Possibly a little. It fades as the sealant cures.
