A permit is typically not required for 'like-for-like' replacements where the size and structure remain unchanged. However, if you are enlarging an opening or changing the structure, the City of Portland requires a permit costing between $145 and $380.
Oregon's strict energy codes require replacement windows to have a U-factor of 0.30 or less. This effectively mandates double-pane or triple-pane glass with Low-E coatings and argon gas fills, which increases the average cost per unit to approximately $825.
Due to the high moisture levels in the Pacific Northwest, fiberglass and vinyl are the most recommended materials. Fiberglass offers the best moisture resistance but costs between $800 and $1,500 per window, while vinyl is more budget-friendly at $400 to $500 per installed unit.
Yes, replacing all windows in a single project can reduce the per-window cost by 15% to 30%. For example, a single window replacement averages $825, but a bulk project of 10+ windows can bring the per-unit cost down to roughly $590 to $700.
