Step-by-Step Velux Window Maintenance Guide

Regular Cleaning of Window Glass

Start by cleaning the glass with a non-abrasive cleaner. Avoid ammonia-based solutions, as they can damage special coatings. Use a microfiber cloth to prevent streaks.

Dusting and Cleaning Frames

Wooden frames should be dusted regularly and treated with varnish or paint when necessary. For PVC frames, just a wipe with mild detergent is enough.

Inspecting and Cleaning Flashing

Check the flashing around the window to ensure no debris or moss is blocking water flow. This prevents leaks and water buildup.

Checking Seals and Gaskets

Over time, seals can weaken. Check for cracks or brittleness and replace them if needed.

Lubricating Hinges and Moving Parts

Apply silicone spray to hinges, locks, and handles at least once a year to keep them working smoothly.
