- Inspect glazing seals, clips, and gaskets periodically to ensure all panels remain secure, sealed, and weather-tight.
- Remove dirt, algae, and organic debris from the frame, base, and corners to prevent corrosion and staining.
- Check doors, vents, and windows seasonally and lubricate hinges, rollers, and moving parts for smooth operation.
- Ensure proper drainage around the greenhouse foundation to prevent water pooling and structural stress.
- Tighten all structural bolts and frame connections periodically, especially after strong winds or seasonal changes.
