What maintenance practices are recommended to extend the lifespan of a glass facade system?

A proactive maintenance program preserves performance and reduces lifecycle costs. Cleaning frequency should reflect environment—monthly or quarterly for sand-prone Gulf cities (Dubai, Abu Dhabi), biannual in cleaner Central Asian contexts (Almaty, Tashkent). Use approved detergents and soft tools to avoid damaging low-e coatings and PVDF finishes on metal spandrels. Inspect and document sealant condition annually; UV and thermal exposure cause sealant hardening and adhesion loss, requiring scheduled resealing (commonly 8–12 year cycles depending on exposure). Check gaskets and compression seals for extrusion set and replace compromised sections to maintain airtightness. Verify anchor torque and check for corrosion on stainless fixings, especially for coastal projects in Muscat or Manama—apply passivation or replace corroded items promptly. Ensure weep and drainage paths are clear to avoid ponding and water ingress. Maintain an asset register mapping panel serial numbers to elevation locations to expedite replacements. Contract with certified façade maintenance contractors who provide BMU operations, rope access teams and façade inspection reports. Regular preventive maintenance preserves thermal and acoustic performance, limits emergency interventions, and supports warranty compliance for metal curtain wall systems.
