Have you ever tried opening your sliding window only to feel it drag or resist halfway? Many clients tell us this is usually the moment they realise their windows need a little care. Aluminium sliding windows are known for their strength and reliability, yet even the best systems perform better with regular maintenance. At our façade company, we install high-quality aluminium window systems, and we always share these simple habits to help them last for years.
Why Maintenance Really Matters
Aluminium is incredibly durable, but sliding windows operate on rollers and tracks that deal with dust, moisture and daily wear. Without routine checks, these factors affect performance over time. Good maintenance not only keeps the window sliding smoothly but also protects the hardware, improves insulation and boosts overall lifespan.
When we install windows for homes, offices or high-rise façade projects, we want clients to enjoy effortless operation for years. These steps help you do exactly that.
Start With Track Cleaning
Clean tracks are the foundation of smooth sliding. Dust, dirt and small debris accumulate faster than most people realise. If you live near a roadside, a busy neighbourhood or an industrial area, the buildup happens even quicker.
Use a soft brush or a vacuum nozzle to clear loose dirt. Then wipe the tracks with a damp cloth and dry them completely. This simple step often brings an immediate improvement in how your aluminium sliding window moves.
Use the Right Lubrication Technique
Once the tracks are clean, lubrication keeps everything running effortlessly. We recommend silicone spray or a dry lubricant because oil-based products trap dust and cause more friction over time.
Apply a light coating on the tracks and rollers, then move the sash back and forth to spread it evenly. Regular lubrication greatly reduces pressure on the hardware and maintains smooth sliding.
Check the Rollers at Least Twice a Year
Rollers handle the entire weight of the glass panel, so they wear down gradually. If your window feels heavy or makes noise, the rollers may need attention.
Lift the sash slightly and inspect the wheels. If they look worn or uneven, a replacement is usually the best solution. Many of the systems we supply include adjustable rollers, which help us restore perfect alignment and smooth movement.
Make Sure Locks and Handles Work Properly
Security is as important as ease of use. Over time dust collects near locks or alignment shifts slightly because of constant operation.
Check whether the lock closes neatly without force. Clean around the latch and tighten any loose screws. Maintaining the locking system ensures your window stays secure and dependable.
Inspect Sealing, Gaskets and Exterior Silicone
Air leaks, noise issues and water seepage happen when seals begin to age. Rubber gaskets may harden or shrink and silicone sealant can develop cracks over time.
Run your hand around the frame to check for air gaps. Replace any damaged sealing and inspect the outer silicone joint, especially before monsoons. Fresh sealing restores insulation and protects the building envelope—something we take seriously in all our façade projects.
Clean the Glass Safely
Use mild cleaners and avoid anything harsh or abrasive. Strong chemicals can damage aluminium surfaces and roller mechanisms. A simple mix of water and mild soap works well, followed by a microfiber cloth for a streak-free finish.
Monitor Alignment for Smooth Sliding
If the window tilts, drags or makes scraping noises, misalignment may be the reason. Small adjustments to the rollers usually solve this, but if the issue seems complex, our team or any qualified technician can realign the sash without stressing the frame.
Annual Servicing Keeps Everything Healthy
Even with regular homeowner maintenance, aluminium windows benefit from a yearly professional check. As façade specialists, we inspect drainage pathways, roller condition, sealant edges and frame alignment. Early detection prevents long-term damage and ensures the window performs at its best.
Final Thoughts
Aluminium sliding windows deliver excellent performance when they receive a little routine care. Clean tracks, smooth rollers, strong sealing and proper alignment make all the difference. At our façade company, we design and install systems meant to last, and these steps help you get the best out of them.
