7. Install Interior Trim
   Attach pre‑cut trim pieces (pine, MDF, or PVC) using ending up nails or brad nails. Fill nail holes with wood filler, then sand and paint as preferred.
8. Final Inspection
   Run a water test (garden tube at low pressure) to confirm that no leakages appear around the frame. Inspect the locking hardware to guarantee a tight seal.

Common Mistakes to Avoid

• Disregarding Rough‑Opening Leveling: An out‑of‑square opening results in operational issues and drafts.
• Over‑Sealing the Sash: Too much caulk can prevent the sash from closing fully.
• Avoiding Flashing: Proper flashing is the very first line of defense versus water damage.
