A 20×20 sunroom in Portland, ME runs $30,000 to $100,000+ installed — and that range is completely explainable once you understand what drives it. Maine's deep frost lines, heavy snow loads, and long winters add structural requirements that national pricing guides simply don't reflect.

 The model you choose is the single biggest cost factor. The WeatherMaster (Model 200) is the most accessible entry point for three-season use ($30K–$50K). The Model 300 steps up to extended three-season comfort ($45K–$70K). The fully insulated Model 400 is built for year-round Maine living with Low-E Argon glass and climate control ($65K–$100K+). Get the honest, locally grounded breakdown before you talk to any contractor.
