1. The installers forgot to properly insulate your windows resulting in cold drafts throughout the winter months.
2. Your newly installed, high-quality windows neither operate properly nor meet your visual expectation due to improper installation.
3. Wood rot and mold exists that the installer neglected to warn you about. As a result, your new window is poorly installed and you have condensation, moisture and a greater chance of mold growth.
4. Your carpets, flooring and/or property are damaged by careless installers.
5. A problem arises post-installation but the installer, a sub-contractor who is paid by the piece, is not willing to help. The dealer or manufacturer will not offer any assistance either because they did not install the windows in the first place.
