Bay Window vs Bow Window Cost in Baltimore MD

What Usually Drives The Price

• How far the window extends from the wall
• Whether the frame is vinyl, fiberglass, or wood-clad
• Labor for structural support and exterior weatherproofing
• How much drywall, trim, plaster, or paint repair is needed
• Whether the opening needs a built-to-fit unit instead of an off-the-shelf size
