After about taking a header on my well-aged wooden steps to my backyard, I made them go away today. They were almost 30 years old. After doing the disassembly, I believe god may have just liked me all these years because none of the material except the redwood planking were rated for outdoor purposes. Oh well, lucky me.
They will be getting replaced by a 12’ by 16’ wood deck - boss’s orders. 
now I have to go into my “Tim the tool man” mode and construct the new deck with stairs. Pray for me.
Good luck finding any actual redwood… I’ve tried to buy some for small reburb projects on some 130 year old outbuildings at my old place in Idaho and have been told you simply cannot buy it.
I get it - there is not an endless supply and we have to stop cutting down those old trees. Just get used to using pressure treated pine, knowing that it will not outlast redwood, but it will certainly outlast us 
Despite being raised by a dad who was extremely handy and could fix anything, I have absolutely zero DIY skills. Honestly, none at all.
In fact, I’d go so far as to say I actually have negative DIY skills. If I try to fix something, it’s highly likely that I will make whatever the original problem was worse and then have to call a professional to fix not only the original issue, but whatever I did to make it 10X worse.
It’s quite embarrassing, but I’ve come to terms that while I may be good at lots of things, handyman stuff definitely isn’t one of them.
I have some skills…with a sledgehammer and a sawzall. 
Ok, I am a little better than that. When working with my brothers doing renovations of High Desert houses that were totally wrecked inside, I got to run the chop saw and be a “human forklift” for getting replacement trusses up on the roof.
It’s going to be a lot of work; but since I don’t have anything else to do, I can take my time to get things right.
Do no harm.
