2.3 Assembly Steps Overview
- Unpack and Organize: Carefully unpack all components and verify against the parts list in the manual. Organize parts for easy access.

5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Doors do not close or align properly. | Uneven base; incorrect door frame assembly; loose hinges. | Ensure the shed is on a perfectly level surface. Recheck door frame assembly steps and adjust framing pieces. Tighten all door hinges and fasteners. |
| Water leakage inside the shed. | Improperly sealed roof panels; gaps in wall assembly; damaged seals. | Verify all roof panels are correctly snapped and wedged into place. Inspect wall panel connections for gaps. Check for any damage to the shed's waterproof seals. |
| Missing or damaged parts upon delivery. | Shipping damage; packaging error. | Contact Greesum customer support immediately with your purchase details and a list of missing/damaged parts. |
| Difficulty with roof assembly. | Panels not sliding easily; tight edge pieces. | Ensure panels are aligned correctly before attempting to slide. Use the provided wedge tool (if applicable) or a similar non-damaging tool to assist with fitting into tight edge pieces. Two people are recommended for this step. |
| Window misalignment. | Incorrect installation; manufacturing tolerance. | Carefully re-evaluate window installation steps. If a gap exists, consider using weather-resistant sealant around the window frame. |
