What drives the range
Windows work is a moderate slice of a full rehab — roughly 6% of a whole-house budget. The high end runs about 2.4× the budget end: finish level and how much you replace (versus repair) move this category more than square footage does. Labor is roughly half the cost, so Connecticut wage levels are baked into every line.
