What affects the price
The final price for impact windows depends on several variables. The biggest factor is the size and type of your window frames, along with the specific glass thickness required for your local building codes. Opting for custom shapes or specialized tints also shifts the total. Installation complexity matters too; if your existing frames are damaged or if the project requires extra structural support, labor costs will increase. Exact pricing confirmed free on the call.
