cost of replacing stairs
Before you bring in a professional, it may be beneficial to have a rough estimate of the costs involved. Keep in mind that no two repair projects are the same, so the cost of repairing a squeaky stair in one location could be priced very differently from needing to replace several steps in another location. The national average for professional stair and railing repair is $750, so that is a good place to start budgeting. Larger projects can run as high as $1,400, and smaller fixes may cost as little as $200.
Cost breakdown. Purchase and Installation - Most manufacturers of pre-built staircases will charge between $800 and $1000 for a set of straight basement stairs, usually all stringers 4 and precut lumber is included and will need to be installed according to manufacturer recommendations.
