I have this botched job a "pro" did for me. Unfortunately there are no bui lding codes here so the only option is to sue in small claims court, and th at is not a sure thing either due to the lack of codes here.
The stairway is 18 steps long, outside up to the attic/loft of my garage. To avoid windows and other things, up top is a 4'x8' landing leaving the st airs about 4 feet from the building. Instead of ordering special order str ingers long enough, he used 2 sets and he did a number on how they join and are supported in the middle of the run. I've been going through multiple idea's on how to fix it (multiple problems) and I've gotten to the point wh ere I'm thinking of making something out of steel U channel that would fit the 2x12 stringers at the bottom edge, centered at the stringer joints, not sure how far to extend it, an I'd weld upside down U's to fit 4x4 posts to set on and be bolted to. Without you seeing this I suppose this is hard o r impossible thing to picture?
Lets say you have an idea that uses wood and doesn't involve welding. How would you join these stringers? I searched and searched and could not find anything like my situation. I believe most builders would have put a 4'x4 ' landing between the two sets. This guy put a not quite double depth step in the middle because he didn't realize he was doing it until he put on th e treads. I plan on cutting that one extra step and sliding the lower set of stringers forward to properly meet the upper stringers. A 4x4 landing i s not possible, the steps would extend too far into the driveway. If you h ave a picture that would be great although I'm not sure where we could post them, I assume they aren't allowed here. Thanks, Tony
