Just a simple (dumb) question - how did my builder attach the plywood to the foundation wall (poured) for the breaker box and the gas manifold. It looks like it was nailed (?) and the nails look like they have square heads. Was this done by hand? Or some kind of nail gun? Are holes drilled first?
Can you tell I want to try and do this myself? I'd ask them but all the houses are completed and its tough enough getting through to them to fix something :-).
