What drives the price of window replacement
Window replacement is priced per opening, but a small double-hung window and a large casement, bay, or custom shape are not comparable units. Frame material, glass package, grille pattern, impact resistance, and exterior finish change product cost. Installation changes when an insert can fit inside a sound frame versus a full-frame replacement that removes trim, flashing, and the old sill.
Hidden carpentry is where window bids drift apart. An insert quote may exclude rotten framing, exterior cladding, interior trim, painting, and lead-safe containment for pre-1978 homes. Another proposal may include full-frame removal, sill-pan flashing, insulation, disposal, and finished trim. Compare the NFRC labels, especially U-factor and solar heat gain coefficient, rather than relying on vague labels such as premium or energy-saving glass.
Worth asking the shop
Is this insert or full-frame installation? How are hidden rot and trim repairs priced? What NFRC U-factor and solar heat gain coefficient will each window have? Are installation and glass-seal warranties separate?
Red flags
Same-day-only discounts, contracts without exact model and glass specifications, measuring every opening as a standard size, or removing old windows before confirming that the delivered units and NFRC labels match the order.
