Tread Brace and the one-board rule

Field notes

The page separates loose treads, low rails, and individual squeaks in its navigation. It describes Ruthie fastening a tread to the stringer and Cal listening from the floor, while explicitly limiting the work to smaller repairs rather than full staircase replacement. It gives a Gay Street, Suite 3 address and a phone number, but the extracted page does not independently establish whether the operation is active.
