Should I make my two steps have the same rise or keep one closer to a typical height?

How to install deck railing top board slanted

You'd just slope the 4x4 posts, set the top rails on them, and fit your 2x4 rails underneath. A slight wedge gap would be present, but that's not going to look terrible. I'd reconsider for a few ...

I am a painter and I build also and I personally will not warranty the work unless it's after 6 months. Pressure treated (PT) lumber takes months to shrink and re-contract on and off so the paint will ...

I'm building a Deck. Is it cheaper to buy wood from a mill rather than a box store like Home Depot?

Should the underside of a deck be stained?

Why does the maximum deck overhang sometimes decrease with joist spacing?

Looks like data entry error to me. The values were reversed for several rows at some point. Considering that they spelled 'fir' as 'fire' in one case, one can assume that accuracy was not a high ...
