Some of the above difficulties may require a visit from your dealer or even our service personnel. Do not hesitate to contact your dealer if you are not comfortable attempting a solution. Some solutions are offered for the convenience of our more technically adept customers. Your dealer can arrange for a factory service call if required after their inspection of your window. If you are unable to contact your dealer, please have your warranty card ready and contact Vinyl Window Designs Limited directly at 905-850-3222 or email to info@vinylwindowdesigns.com for assistance.
