OUTDOOR STAIRS – Stringer rot repair?
Boss showed me a set of outdoor stairs hung off phone poles sunk in dirt. Four landings as it comes down the hillside. Three waves of repair thus far, judging from the different woods used. Looks like fun. Don’t get much deck/stair repair so your ideas are welcome.
The bottom flight has 48″W treads (2.5 x 11 = 3×12?) hung off metal stair backets on the non PT stringers. OK except these two. They have termite damage and one was secured with some deck screws. Not anymore.
There is about 1.5″ of the end of the tread gone to rot and a matching hole in the stringer. Tread above is a bit better.
Currently I have a 2×3 stuffed under the bad end to hold it up. Very Gomer. Tomorrow I will see about building a wood bracket that will hold it up and screw off to the stringer while we find the right wood, paint it, etc., etc.
I’d just pull the stringer and replace it, but it doesn’t head out at the landing. It is lagged into the poles top and bottom, then runs under the deck for at least 6″. When it ran out they attached a cleat across the gap and screwed the Trex to that. While I could pull up that Trex, I wonder is there is a simple, yet elegant solution. (No, not a flamethrower. Tempting, but…)
Looking for Best Practices suggestions on a repair – not a rebuild <g>.
* Sister the stringer between the posts top and bottom?
How best to attach treads (hole in first stringer)?
Run new tread through to butt on new sistered stringer
* Insert a dutchman on the existing stringer? How would it carry the tread, being loaded in tension? Make it wide and thru-bolt it?
* Other good ideas that you have …
