Cost to Install Bay Windows in Lexington SC

A bay window can change the feel of a room fast, but the final bill depends on more than just the glass and frame.

What drives the price

Size of the opening and overall projection. The frame choice, including vinyl, fiberglass, or wood-clad options. The glass spec, including low-E glass and other options for heat control. Whether the opening needs extra support or reframing. The amount of trim, siding, and drywall work after the unit goes in.
