In the last 20 years, we have done over 18,000 inspections. Many of the homes we’ve inspected have older Anderson Casement windows. (Casement windows are the ones with cranks, and double-hung windows are the ones that slide up and down). During our inspections, we operate many of the windows. Unfortunately, many of these casement windows are difficult to open and close because of damaged crank mechanisms. Often, the crank handle gears are stripped, or the mechanism is faulty. It appears that Anderson produced these mechanisms for many years until they finally improved the design.
FYI, Typical replacement parts cost less than $50, and it is not difficult to change the mechanisms. The repairs can be accomplished relatively quickly by a handyman.
