Step 1: Measure and Prepare Opening

Measure the window space meticulously to ensure a snug fit. Clear away any debris or obstructions from the designated area.

Step 2: Remove Old Window (if applicable)

Carefully dismantle and dispose of the existing window if one is in place. Handle the removal process with attention to prevent damage.

Step 3: Check for Level and Square

Verify the opening’s levelness and squareness meticulously to prevent future complications in the installation.

Step 4: Install Flashing

Achieve a refined interior appearance by fitting interior trim around the window, covering gaps and providing a complete look.
