• Gain access to Requirements: If the windows are on the 3rd story or greater, scaffolding may be essential, adding a considerable set cost to the project.

Even the best-installed windows need care. Installers normally advise the following:

1. Cleaning Tracks: Keep the side channels devoid of debris to prevent the sashes from jamming.
2. Lubrication: Periodically use a silicone-based spray to the tracks or pulleys. Prevent WD-40, as it can draw in dust and grime.
