Does Anyone Know Why Holes Are Being Drilled

[hc4361]

in the walls of my neighbours' house? The man has drilled holes at the corners of the house about 4ft from the ground, inserted some sort of probe attached to a black box (pocket camera size); removed the probe after a couple of minutes and sealed the hole with a mastic gun.

After drilling several holes he attached the black box thing to a tablet pc, I think.

He's been about an hour.

I could ask the neighbour but I don't want to appear nosey :)

Several of the posts have it.

It is almost certainly checking the wall ties or suitability for insulation.

Maybe it's a build up of air pressure inside the house and they're drilling holes to let the air out?

- or -

Perhaps someone left the tap on in the bathroom and it's flooded so they've drilled holes to let the water out?

- or -

They might be checking to see if there are any bodies bricked up behind the walls? Have you seen the neighbour's wife recently?

- or -

It could be so your neighbours can look out through the holes and watch you without being seen?

Or they might just be trying to make the house lighter by making holes in it so it uses less fuel?
