Document the condition
Note location, timing, weather relationship, changes over time, and any previous work. Photos and simple measurements can improve the first conversation.
Read the local context
Lansing's housing stock runs in clear waves: modest early-1900s frame houses near the original river-crossing neighborhoods, a long run of bungalows and postwar ranches built as Oldsmobile and REO Motor Car Company employment pulled workers into the city through the mid-20th century, and newer construction in outlying pockets after the Oldsmobile assembly plant finally closed in 2005. A window opening cut for a 1920s frame house, a 1950s ranch, or a 2000s infill build calls for very different sizing, trim, and flashing decisions, so matching the replacement to the era of the opening matters as much as the glass package itself.
Ask what will be hidden
Installation method, flashing, sill condition, frame material, glass package, trim restoration, and solar exposure matter as much as the unit itself. The written scope should explain the preparation and verification that will no longer be visible at completion.
Compare complete scopes
Look for protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
What official local sources add
The City of Lansing maintains dedicated floodplain-permit and stormwater/sewer program pages, including a Basement Backup Protection Program, because the Grand River and Red Cedar River corridors that run through the city carry mapped flood risk. Work proposed near mapped flood hazard areas, or work affecting drainage and grading, should be checked against current City of Lansing requirements before it begins.
