$41k one-car garage?
This is a quote for enlarging an attached single car garage. The existing garage has a passage door and 2 windows. These will be retained and relocated.
The enlarged garage will have a single garage door in front. The existing garage's door is also in the front.
The roof shingles and siding, which will be matched, are not in any way extraordinary. Existing soffit and facia are from 1937, so they might be slightly different from the cheapest thing available to day, but they are no where near grand. It is not an especially tall garage.
The garage is easy to access. It is not in a tight space, on a hill, or far from the street.
The price seems insane to me, perhaps double what it should be. That is a gut reaction. I know nothing about the nuts and bolts.
Do you see something I could omit or question?
