Milgard’s window and door hardware is protected by special coatings and lubricants. However, these coatings and lubricants can be damaged by common household products and harsh environmental conditions, such as coastal and industrial areas. These conditions can cause the windows and doors to become more difficult to operate and cause the hardware to wear or corrode faster.
Loss of functionality of hardware in highly corrosive environments, which includes any Home located within two miles of salt water and any Home located in the State of Hawaii, is excluded from Full Lifetime Warranty coverage.
In order to maintain the appearance and function of your hardware for years to come, we recommend that hardware be inspected once a year (more if necessary) and cleared of dirt and grime build up.
Please reference the FAQ questions: How do I clean my hardware? How do I lubricate my hardware?
