Windows and doors are essential elements in every building, not only providing light, ventilation, and access, but also ensuring comfort, energy efficiency, and security. Like any long-term investment, proper care and maintenance are necessary to keep them functioning well and looking new. With the right upkeep, modern windows and doors—whether PVC, aluminum, steel, or wood—can last for decades. Below are practical tips to help you extend their lifespan. 1. Regular Cleaning Clean windows and doors at least twice a year, or more often if you live in a coastal or dusty area. Use mild soap and water for glass surfaces, wiping with a soft cloth to prevent scratches. Avoid harsh chemicals or abrasive materials that could damage special coatings. For frames, PVC and aluminum should be cleaned with non-abrasive cleaners, while wooden frames need gentle cleaning and periodic refinishing to prevent moisture damage. 2. Care for Tracks, Hinges, and Hardware Dirt and dust often build up in sliding tracks and around hinges, causing windows and doors to operate less smoothly. Vacuum tracks regularly and wipe with a damp cloth. Hinges, locks, and handles should be lubricated once or twice a year with silicone spray or light oil to ensure effortless movement. Avoid heavy grease, as it tends to attract more dust. 3. Inspect Weatherstripping and Seals Seals and weatherstripping play an important role in energy efficiency and water resistance. Over time, they can crack, shrink, or lose flexibility. Inspect them every season and replace when necessary. Also check caulking around frames; reapply if you notice cracks or peeling. Well-maintained seals reduce air leaks, lower energy bills, and protect interiors from moisture. 4. Moisture and Drainage Management Windows and doors are designed with small drainage holes to let water escape. Keep these openings free of debris to avoid water accumulation and leaks. For wooden frames or doors, look for swelling, peeling, or rot. Sand, repaint, or reseal exposed areas to maintain a strong moisture barrier. 5. Glass and Frame Care Examine glass panels for cracks or chips, as even small damages can spread over time. Replace damaged panes quickly to maintain safety and insulation. Check frames for dents, warping, or corrosion, depending on the material. Tighten any loose screws in handles, locks, and hinges. 6. Proper Use and Handling Gentle operation is key to long-lasting windows and doors. Avoid slamming them shut or forcing them open if they stick. For sliding systems, do not overload handles or lean on panels. Small habits in daily use can significantly extend the product’s life. 7. Seasonal Inspection Before rainy or winter seasons, check windows and doors for insulation, water tightness, and overall performance. After heavy storms, inspect frames, seals, and glass for possible damage. Preventive maintenance ensures long-term durability. Conclusion Windows and doors are designed to last 20–30 years or more with the right ma...
