What Maintenance Practices Are Recommended for Aluminum Curtain Walls in High-Rise Projects?

Regular maintenance preserves performance and appearance of aluminum curtain walls and avoids costly repairs. A practical regime includes visual inspections twice annually and after extreme weather events to check sealants, gaskets, visible fasteners and glass integrity. Clean finishes periodically using manufacturer-recommended detergents to remove salts, sand or urban pollutants—critical in coastal Gulf cities and dusty Central Asian climates. Replace perimeter sealants on a lifecycle basis (often 7–15 years depending on material and exposure) before failure occurs to maintain airtightness and watertightness. Check anchor bolts and brackets for corrosion or loosening, especially where dissimilar metals join; tighten or replace with stainless alternatives if needed. Drainage paths and weep holes should be cleared to prevent water buildup behind cladding. For buildings with access challenges, coordinate rope-access or façade access platforms into a maintenance plan and budget. Keep records of inspections and repairs — this helps during warranty claims and for long-term asset planning. Finally, follow manufacturer guidance for finish touch-ups and recoating schedules; doing so significantly extends service life in aggressive climates from Dubai to Almaty. A proactive maintenance program tailored to local environmental stressors preserves façade performance and adds to building value.
