Another option is a pre-cast concrete stairway sized to fit the steel door unit you select. When the foundation contractor pours the footings and foundation, a cutout is left sized for the pre-cast stairway. Once the foundation had cured, the pre-cast stairway system is delivered and dropped into place. Typically, the pre-cast stairs were prepped with a self-sealing adhesive and attached directly to the foundation wall. Steel anchors hold the stairway to the foundation and backfill sits under and around it to insulate the stairway and keep it in place.

Access for Existing Homes
For existing homes, either solution is possible, but there is the added headache of clearing out around the foundation and cutting through the existing foundation wall. Be sure to select a qualified foundation contractor and follow codes for headers, supports, and bracing. Once the footings have been placed, you may choose to construct an areaway foundation or install a pre-cast entry solution like the one we used.

Door Installation
In all cases, the door unit is assembled on site and installed on top of the foundation wall. If you are working with concrete block, experts suggest filling the cores of the top rows with wadded newspaper. The assembled door unit is then lowered in place and blocked so that a concrete cap can be shoveled underneath. Finishing the cap by sloping it away from the bulkhead and smoothing the concrete will allow for water runoff and a leakproof seal with minimum caulking. If you select the pre-cast stairway, the cap is already in place and door-ready.
