- Inspect your windows every spring.
- Clean the aluminum frames with a non-abrasive cleaner or water mixed with gentle soap.
- Verify the sealing joints of the windows as well as the joints of the frame that are touching the building’s envelope to ensure watertightness.
- Occasionally apply a lubricating spray with silicone to the metallic hardware only.
- Be careful not to block the small openings intended for water evacuation.
- For the slider windows it is important to clean the sill (bottom of the window).
- It is important to control the level of humidity inside the house, to eliminate the formation of condensation on the internal surface of the glass.
- Avoid any contact of paint, dye or solvent with the weather strip and the hardware of the windows.
- Aerate rooms regularly to lower the humidity. Furthermore, open curtains and/or blinds to increase the air circulation.
- It is the responsibility of the customer to inspect and change, if necessary, the weather strips and the caulking joints of a window. This comes as regular maintenance of windows.
- Note : Occasionally, when certain weather conditions happen, condensation can form on the outside of the energy efficient sealed unit (glass). This result is not a window defect.
