Is the installation warranty separate from the window warranty or the same thing?

Installation warranty and window warranty are typically separate coverages - the window manufacturer covers the product itself, while the installer provides warranty on the workmanship and installation.

Window Product Warranty covers defects in the window itself - things like seal failures in double-pane glass, hardware malfunctions, frame warping, or coating deterioration. These warranties typically run 10-20 years for quality windows and are provided directly by the manufacturer like Jeld-Wen, Pella, or Marvin. The warranty follows the window regardless of who installed it.

Installation Warranty covers the actual installation work - proper fitting, air sealing, flashing, trim work, and ensuring the window operates correctly in the opening. This includes issues like air leaks around the frame, water infiltration due to improper flashing, or operational problems caused by installation errors. Licensed installers in Ottawa typically provide 1-2 years of installation warranty coverage.

Why separate warranties matter is that installation problems often show up in the first year or two, while product defects may not appear until years later. Poor installation can actually void your window warranty if moisture damage occurs due to improper sealing or flashing. That's why choosing a licensed, insured installer is crucial - they'll stand behind their work and know how to maintain your product warranty.

In Ottawa's climate, proper installation is especially critical given our temperature extremes and freeze-thaw cycles. A quality installer will ensure both warranties remain valid and work together to protect your investment.

For peace of mind on both product and installation coverage, request details on warranty terms from your installer before starting the project.
