Note the condition
Where it shows up, when, any weather pattern, how it's changed, and prior attempts to fix it. A handful of photos and basic measurements improve that first conversation.
Read the local context
Which housing category applies decides the recommendation before any product comparison. Historic-district properties hold original sash that is frequently repairable, in openings rarely built to a standard size, and review can reach the decision itself. University-area housing commonly carries a mix of units replaced one at a time between tenancies, so matching what exists is its own problem. Mid-century ranches typically have aluminum single glazing at the end of its life, where the frame is the weak point. Measure openings individually rather than trusting a plan.
Ask about what gets covered up
Installation approach, flashing, sill condition, frame material, glass package, trim rework, and how much sun the wall gets under the oak canopy or in the open all matter as much as the window itself. A solid scope explains, in writing, the prep and verification steps that vanish from view once the work is done.
Line up full scopes
Protection measures, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and the change-order process should all be part of the comparison.
What official local sources add
Historic-preservation review is the item that governs this trade, and it is the one worth settling first, because on a designated property window review can reach sash configuration, material and profile rather than merely thermal performance -- and may carry an expectation that original units are repaired. That is determined by address, not by the look of the street. The rest of this framework reaches an opening in a wall hardly at all: karst geology, springsheds and drainage concern the ground, and tree impacts only matter if access equipment has to work under protected canopy.
