Preparing for Installation

Tools & & Materials Needed

  • Measuring tape, level, and square
  • Drill/driver with bits

    Apply a continuous bead of exterior‑grade sealant around the outside border where the frame fulfills the siding. Inside, utilize low‑expansion foam or backer rod to fill any gaps, then seal with paintable caulk.

  7. Install Interior Trim
    Attach pre‑cut trim pieces (pine, MDF, or PVC) utilizing ending up nails or brad nails. Fill nail holes with wood filler, then sand and paint as desired.

  8. Last Inspection
    Run a water test (garden pipe at low pressure) to confirm that no leaks appear around the frame. Inspect the locking hardware to ensure a tight seal.


Typical Mistakes to Avoid
  • Neglecting Rough‑Opening Leveling: An out‑of‑square opening results in operational issues and drafts.
  • Over‑Sealing the Sash: Too much caulk can avoid the sash from closing completely.
  • Skipping Flashing: Proper flashing is the very first line of defense versus water damage.
  • Utilizing Improper Fasteners: Use corrosion‑resistant screws; galvanized or stainless steel are suggested.
  • Disregarding Local Building Codes: Some jurisdictions require specific flashing or egress factors to consider.
