I recently had a shed built by what I thought was a reputable company. Now I'm in doubt about that quality of the construction, but I don't really have a reference to compare it to. I'm looking for experienced opinions.

At least one of the builders apparently had a problem holding the nail gun straight. Dozens of nails missed the studs, including some coming up out of the bottom sills of window frames. Here's one of the worst areas, in the roof. (The city building inspector passed this.)

The prebuilt door frame is screwed tightly to the framing on the hinge side, so there's a half-inch gap on the lock side. As a result, the deadbolt is anchored in nothing but the wooden door frame and a couple of questionable-looking screws.

Two of the windows are sitting directly on the bottom frame, leaving a large gap at the top. The other is visibly crooked. When I had new windows installed in my house, the builders carefully shimmed the windows so they were centered. I anticipate problems finishing the window casing with the large gap at the top.

The windows are identical to those on my house, but the shed builders used molding half as thick, leaving this huge gap and protrusion. I'm concerned that water will enter here.

Am I right to think that these are problems that should be fixed?
