Window Maintenance


The most frequent maintenance operation is cleaning, which can be performed manually or with devices such as a squeegee. Some owners hire professionals for the regular cleaning of windows which are situated at considerable heights and require the use of elevated surfaces such as ladders, high platforms or mobile platforms, depending on the height. Purposely designed cleaners should be used as they provide the best results in terms of not leaving smudges. Certain types of windows, particularly sash windows, may need to be removed for cleaning. When cleaning glass surfaces, all cloths used should be grit and lint free and applied with a minimum to moderate pressure. An emphasis should be placed on rinsing, in order to avoid streaks and smudges. The exterior side of the window frames should be cleaned regularly to prevent the accumulation of dirt; warm soapy water should be used, or another diluted detergent.

The following types of products should always be avoided:

pressure washers

abrasive products

corrosive cleaners, particularly on window frames

Moisture reduction

Condensation is often noticed on the inner side of the sashes in rooms with a high level of humidity, such as kitchens and bathrooms. Not ventilating a room can be a health hazard as it can cause fungus to develop on walls and ceilings; windows are essential in managing condensation as they provide fast and effective ventilation when opened. If windows cannot stay open for too long for practical reasons, other devices can be installed, such as fans.


Also, inspections should be carried out every five years on average, in order to ensure the proper functioning of the windows and avoid the worsening of any existing problem. Professionals will check for wood corrosion (which is very common) but also malfunctioning hinges or alternatively, damaged cords, pulleys and weights, depending on the specific type of windows.
