Should I Use Pressure-Treated Building Materials for My Exterior or Deck Stairway?
Maybe, with a possible
I am not a big fan of pressure treated lumber and have been ridiculed by construction workers, handyman and do-it-yourselfers for quite some time now.
The bottom line is simple, pressure treated lumber might not last as long and I stress this particular point or much longer than regular construction standard building materials all the time.
I'm not a big fan of using pressure-treated materials for stair stringers, treads, risers or joist and would only use it as a bottom plate for wall framing and to attach the bottom of the stair stringers to a concrete building foundation or pad.
The key to anything, including stairways whether they were built out of pressure-treated or non-pressure-treated lumber, will always go back to maintenance. If either one of these stairways are poorly maintained, then there's a good chance neither one will outlast the other.
I've removed, repaired and replaced exterior stairways built out of both materials and am not entirely convinced, that you will be getting your money's worth, building an entire stairway or deck out of pressure-treated lumber.
The best advice I could give anyone on whether or not to use pressure-treated lumber for a porch or deck stairway, would be to see what others in their community were using and whether or not they were happy with the results.
Now, don't get carried away and listen to a neighbor tell you how wonderful their pressure-treated deck and stairway actually is, when it's only a few years old. The same would hold true for a deck built out of construction standard lumber.
The bottom line is, if everyone tells you that this or that is the only way to go, without any rational validation, then they're only going to be guessing.
