Window Replacement in Pennsylvania is 4% below the national average of $6,493. This is primarily due to higher labor costs and stronger demand in Pennsylvania.
Pennsylvania experiences a humid continental climate with cold, snowy winters and warm, humid summers, with meaningfully harsher winters in the Pocono and Allegheny regions than in Philadelphia and the southeast corridor. Freeze-thaw cycles, heavy winter snow loads in the north, and historic-district density in Philadelphia and Pittsburgh all influence project costs. For window replacement projects specifically, this means timing and material selection are key factors in both cost and quality.
