I built my large deck in 2009 to accommodate my daughter's first wedding. It's all treated lumber, guaranteed to last fifteen years. Except if you put a flower pot on the wooden deck. After three or four years the constant moisture under the deck rots even treated lumber. A couple of weeks ago, Milady and I learned this lesson when we moved some flower pots and found that the deck underneath was rotted. So, I had to replace four deck boards and decided that this morning would be a good time to accomplish that task.
At about 8:00 I hied myself to the lumber yard and picked out four nice, 16' deck boards, treated lumber. I specifically inspected each board to make sure that it was straight and relatively free of knots or other inclusions that would limit its useful life. I had to go through about 24 boards to find the four I wanted, but I checked out, loaded them in the truck and took myself home.
After ripping out the old boards, I commenced to installing the new boards. Two of them had warped on the way home, simply from the difference in temp and humidity from the time I took them out of the lumber yard to the time I got them home.
