Siding Installation in Montana: Local Market Insights
Montana experiences a semi-arid to continental climate with long, very cold winters and short, warm summers east of the Rockies, and heavier snowfall and mountain conditions west of the divide. Exterior work in most of the state is limited to May through September, and frost protection for footings is a core part of any foundation scope. For siding installation projects specifically, this means timing and material selection are key factors in both cost and quality.
Less regulatory burden and simpler permitting processes help keep overall project costs down.
