Last week we worked on the back steps to the deck. We decided last year to save this project for the hot part of the summer because it is in the shade. Well guess what???? It wasn't really in the shade. It could be that in the fall it is in the shade but it isn't in the shade in the summer.
We installed risers and replaced any treads that were in bad shape. We also replaced the posts on the bottom steps and replaced the short, rusted lag screws on the other posts with the proper length carriage bolts. Between the risers and the carriage bolts, the staircase seems much sturdier.
