How do I know if a shed is built well?

The Short Answer

A well-built shed shows its quality in the parts you can't see from the driveway. Check four things: floor joists on 16-inch centers (not 24), wall studs on 16-inch centers, LP SmartSide or comparable engineered siding rather than thin plywood, and a properly trussed roof with real decking and a warrantied covering.

Then check the details that reveal care: caulked seams before paint, drip edge on the roof, pressure-treated skids and floor framing, and doors that hang square. A company that does these things right will tell you about them without being asked.

Why it matters

The difference between a shed that lasts 5 years and one that lasts 30 is almost entirely in framing, siding, and moisture details — none of which are visible once it's painted and sitting on the lot. Knowing what to look for lets you judge quality instead of trusting a sales pitch.

Real examples

Joist spacing you can feel

Stand in the middle of the floor and bounce. A quality 16-inch-on-center floor feels solid; a bouncy floor usually means joists are spaced too far apart.

Moisture details

Caulked seams, drip edge, and pressure-treated framing are what keep Texas rain out. Their absence is why cheap sheds rot at the base first.

Common mistakes

  • Judging by looks alonePaint and trim hide framing shortcuts. Ask what's underneath before you decide.
  • Ignoring the floorThe floor takes the most abuse and is the most expensive thing to fix later. Thin decking and wide joist spacing are red flags.
  • Not checking the doorsDoors that stick or sag out of the gate signal a building that wasn't framed square.
