Windows are certainly a beautiful focal point in your home and we want to make sure that they remain in good working order. Your windows should open and close with reasonable ease as designed. And we will take corrective action as necessary to meet the performance standard. You don't have to register your windows because Van Metre has taken care of that for you. You have a limited lifetime warranty, meaning there are certain parts and components covered if your window balances need the following: adjustment, repairs—such as your windows not latching properly, or replacement due to a major defect.
