Title: Porch deck stairs
Post by: dug on July 23, 2010, 09:04:24 PM

I am getting ready to build the stairs for my front porch and am unsure how the stringers land and attach at the base.

I am going to pour a concrete pad where the stairs will land. I'm guessing that you don't want the stringers, even pressure treated ones, in direct contact with the concrete. It would seem better yet to have them a half inch or so above.

Is there a bracket made for this purpose, Or another good way to do it?

Well to be honest it seemed a little vague. ??? It says to attach the stringers with bolts to some sort of bracket to the concrete, and makes no mention of avoiding direct wood to concrete contact. I'm certainly no expert but having the stringer rest directly on the concrete doesn't seem like too good of an idea to me.

I know they make the post brackets with about a 1/2 inch metal standup to avoid moisture problems, just thought there might be something similar for the stairs.

I am wondering what others may have done. I will have at least four stringers on these steps if that makes a difference.

I've posted a bunch of stair scenarios, maybe someone remembers a thread or two they could bump up :)

Remember you can use a moisture break membrane between things like PT stringers and concrete. That breaks the capillary action.

Here is one possible old tread that has input from PEG and others.

Your using pressure treated lumber right?

Setting PT on concrete or dirt is how it's generally done. here's a set of stringers attached to a 2x12 PT that will be set on a concrete base hand mixed out of sack redi mix after the strings where set in place and staked up in place.
