In Bletchley, as everywhere, if a roof lantern pane looks cloudy or wet between the two layers of glass, the sealed unit has failed and moisture has got inside. Send photos and we'll tell you what we think has failed.

What you might be seeing

  • Fog, droplets or white bloom between the panes
  • One pane looks hazier than the others
  • Misting that comes and goes with the weather

Why it happens

Water sitting on the edge

If the unit's edge sits in water because the eaves don't drain, the seal fails sooner.

Movement and age

Thermal movement and age wear the seal; units at the bottom of the lantern often go first.

Covering Bletchley and nearby

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

Bletchley is around 13 miles from Aylesbury, and both are within our Buckinghamshire coverage.

Do you need permission in England?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
