1. Keep the right instructions
Store window and hardware references with the installation paperwork. PVC, coated aluminium and painted timber do not necessarily use the same care products. Ask for the instructions matching the actual finish and record previous work. These details help you describe any problems later.
2. Clean without damaging surfaces
Kömmerling recommends lukewarm water, a soft cloth or sponge and a suitable mild cleaner. Avoid abrasives, solvents and tools that could scratch. Remove loose dust first and check compatibility with neighbouring surfaces. For timber and special finishes, follow the relevant manufacturer’s recommendations.
3. Look at seals and accessible areas
During cleaning, look for seals that have slipped out of their grooves, torn or collected deposits. Photograph anything unusual and identify its position on the window. Do not choose a replacement seal just because it looks similar. Ask for the compatible reference and care method; a hardware product is not automatically suitable for rubber.
4. Care for hardware as instructed
SIEGENIA distinguishes care of moving parts from adjustment and replacement. Its TITAN instructions specify suitable lubricants for particular points. This does not mean spraying a product throughout the mechanism. Confirm which points users can access and the applicable intervals. Frequent use and exposure are useful topics for a maintenance discussion.
5. Know when to ask for help
If the sash rubs, the handle resists or a part appears loose, describe what you observe without forcing it. Do not remove the sash or adjust hinges to experiment. Photograph the overall window and the detail, then request a check. If operation seems unsafe, stop using the element until it has been assessed.
6. Keep a simple maintenance record
Use the intervals in the instructions supplied for your elements and set a reminder. Record cleaning, products and observations. Dated photographs help track changes and distinguish one window from another.
- Window reference and hardware identification if available.
- Date, product used and work carried out.
- Displaced seals, unusual marks, rubbing or closing difficulties.
- The question sent to the professional and the response received.
