Skylights and roof windows have increased in popularity in recent years and are becoming a staple of the modern home. It is therefore important to know not only how to install them well, but how to clean them after installation, so you are delivering the best possible product for your customer.
There are many factors that go into cleaning a skylight or roof window, including safety, efficiency, and even recognising when and when not to clean. Read our guide on how to clean skylights or roof windows safely and effectively.
Safety is an important practice when it comes to cleaning any roof window. Since these windows are usually out of reach, cleaning during installation is most efficient. Equipment and extra protection is sometimes required. When cleaning, it is important to follow safety procedures – many will be inline with installation safety procedures.
Centre pivot roof windows can be cleaned even from inside the room by rotating the sash. Some of the roof windows are equipped with a barrel bolt, which can secure the sash in cleaning position. Read our step-by-step guide on how to clean the exterior of a roof window.
1.Clean water will normally be sufficient for cleaning the pane. Non-abrasive household cleaners can also be used. Avoid contact from silicone with the pane. Soft water is best for cleaning panes, therefore, in hard-water areas add a small amount of detergent to soften the water.
2.Soak the skylight or roof window glass with the solution, loosening any dirt and debris present from the installation.
3.Next, use a mild, non-abrasive glass cleaner as well as a soft brush or other non-abrasive applicator, to clean the glass. A squeegee can also be helpful.
4.The cleaning solution should be removed with a lint free cloth or soft sponge immediately to prevent streaks.
5.Keep any metal parts of the cleaning equipment from touching the glass, or any other abrasive materials, as these could damage the glass.
6.For hard to remove spots like tree sap, label adhesive, paint or other construction material, you can use a small, new razor blade. If it’s needed, the razor should only be used in one direction, to avoid damaging the glass. This should only be done on very small and stubborn spots - for example, if construction material has been splashed on the window.
7.Rinse the glass. If the skylight or roof window is cleaned from outside the roof and the window is closed, a hose can be also used. Avoid using high-pressure jets, especially from bottom to upwards direction, because the direct high-pressure water stream can cause water leakage on the window.
Interior surfaces can be cleaned simply with a damp cloth, as well as using a mild, soapy water solution against tougher dirt. If the window has become dusty during installation, we recommend cleaning both the exterior and interior to deliver the best for your customer. We also advise informing your customer of the best way to clean the interior of their new window.
Not paying attention to the condition of skylights can damage their quality.
