Just digging? Or digging, build stairs (concrete including proper drainage), cut foundation wall for door, frame & install door? If the latter, perhaps 12k and counting, but can vary greatly.

Depends on how deep, type of wall you have, and what other add-on's (lighting, overhang, finished on basement side, ) . etc.

Digging? I have been digging as necessary for 60 years and for such a small job, I would dig it by hand. The Chinese built runways for B29's by hand in WWII, using buckets for hauling materials.

In a cold climate, you will also have to excavate and underpin the existing foundation up to four feet further down and to the sides to prevent frost damage to the wall.

i have had a quote to install a stairwell into a basement..It is necessary by code to have an egress out from basement prior to finishing it..Cost of 4600 dollars would be the excavating,cutting of wall, installing a set of precast concrete stairs and a bilco-type door..not included is an interior door at basement..stairwell is bolted into basement walls

Hi,
I am also interested in excavating and installing double french doors including concrete foundation and stairs and drainage done correctly. Any idea what the cost and who to go to?
Thanks,
Calvin
