What Your Deck Should Actually Feel Like — A Homeowner’s Inspection Checklist

We regularly get calls from homeowners asking what they should reasonably expect from a deck — and the answer usually comes down to a handful of clear, checkable things. A gate should operate without jamming, with roughly an inch of clearance, and it should have a proper diagonal brace. A deck should not develop black spots across its surface, and it should not sag noticeably between the joists.

These calls come up often enough that we’ve inspected competitors’ work a few times a year, preparing homeowners with a clear list of deficiencies they can use to negotiate with their contractor. It’s worth saying up front: in most of these cases, the homeowner paid a low, “budget” price for the work — and the deficiencies usually trace directly back to that.

The single most common design flaw we see is a step of 11 inches or more just outside an exterior door, often with visible marks on the wall from where a previous deck sat higher. That step height is more than just uncomfortable — it’s a genuine safety hazard, and it makes a deck feel wrong to use every single time you walk out the door, which defeats the purpose of building it in the first place.

If you’re evaluating a deck, whether newly built or one you’re considering buying a house with, these are the checkable basics: gate clearance and bracing, joist deflection, surface staining, and — critically — the step height transitioning from the house.
