Sheetrock damage - Nail popping 1

[msquared48]

Anyone ever heard of an unpatterned nail popping in walls occurring in multiple locations in an old residence after new vinyl windows were installed?

I could attribute it to a humidity change, due to the new windows, possibly related to the type of nails used, but it seems a stretch.

Archie: I said on the inside and outside walls, true, but both locations were inside the structure.

Are you sure these are new nailpops? I often have people show me new cracks, nailpops, etc. that they just noticed for some reason, but were often times present for a long time. The crack looks like a common stress crack often seen at the top corners of windows or doors.

If these are new conditions, changes in humidity would be a likely cause.

They are all new.

Did they use expanding spray insulation foam around the windows?

I don't know. I'll have to find out.
