The short answer

The short answer

Window Replacers uses an approved insert-replacement baseline, then applies an approved location factor when one is available. A final insert proposal still depends on a suitable retained frame, exact product fit, perimeter detailing, trim, access, and documented repair exclusions.
Published ranges are national baselines or clearly identified geographic adjustments from the active Window Replacers pricing model.
