Windows and doors warranty and service.
Windows and doors warranty and service are in some ways similar to the warranty you get on a major appliance like a furnace. Windows, doors and large appliances require professional installation to ensure their proper operation and long life. If you got it installed by your general contractor or by yourself there will be significant limitations to the coverage. There are also significant differences as well. Most important one is that once a door or a window is installed, it can not be removed without the damage which would render the item unusable. Certain things can be repaired and adjusted, e.g. broken glass, hardware.
Reputable windows and doors manufacturers/dealers that stand behind their product and their craftsmanship all include a lifetime transferable non-prorated warranty and service in the price. They have no issue backing up their work with a comprehensive written warranty. Companies not confident in their technicians tend to offer the manufacturer’s (parts only, no longer than 10-15 yrs) warranty. As for the true value of any promise and service quality, the best strategy is to research the company’s reputation and look up the old customers’ reviews.
Reading and understanding everything about written warranty needs to be done before signing the contract. All concerns regarding the warranty should be easily addressed by a company representative. Exclusions and limitations shall be added to the contract in writing.
