Casper Screens doesn’t provide refunds on our Pre-Cut and assembled retractable screen doors. It’s the customer’s responsibility to ensure that the appropriate measurements are taken prior to submitting your order. If any questions do arise regarding measuring of the screen prior to placing the order please call our office at 877-745-5525. In the event of damage during the shipment of the product, Casper will make every attempt to ensure customer satisfaction up to and including providing any replacement parts and assistance required. If a part needs to be cut to a different dimension, Casper can recut the parts after the order has been shipped back to our office location.
