INSTALLATION: Please remember than non-professional installation can make any product or warranty worthless. Replacement window installation is not the task for a beginner or amateur do-it-yourselfer. Windows need to be installed plumb, level and square. They need to be suspended in the actual rough opening. Improper installation can result in distorted window frames that allow that allow air and water to get in.
To achieve the best fit and finish, it is best to use the window company’s factory-trained installers.
Most installers put windows in one room at a time to make sure that the house is not open to the elements. Reputable dealers and manufactures make certain that the installers clean up after themselves and check the windows for proper operation before they leave. In case, you can and should insist that a representative of the selling company inspect the process before you complete payment for the work. This way all of your concerns will be addressed by a representative of the company and you will be satisfied with the job before you pay.
>WARRANTY: A warranty is only as good as the product it covers and the company who stands behind it. Find out what would happen if the dealer goes out of business or no longer carries the brand of window you bought. Will the product be replaced or refunded if defective? Make certain too, that the company who makes the window is reputable and easy to reach. Find out who would actually be performing any service work. Would the service person be from the dealer, the distributor or the manufacture? The warranty should be non-prorated for a least two-years and cover both the parts and labor, for as long as you own the home.
