I presently have a wood front staircase with seven steps 6 feet wide. There are four stringers supporting the steps and aluminum railings on each side. I want to update to exposed concrete precast treads, but I'm not sure how best to support the extra weight or the cost of having a contractor do the job properly.
Keith,
Rough estimate for precast steps of normal dimensions would range from $3500 to $4500, delivered and installed.
Good morning,
It is likely your existing stairs are not supported on the base. It is best to put in a concrete footing at the base to support the weight and prevent movement.
