This tutorial provides a step-by-step guide on how to install a window in new construction settings. The process is tailored for beginners looking to tackle this DIY project efficiently. Installing a window correctly is crucial for energy efficiency and preventing water damage, so follow these steps carefully.

Step 1: Gather Tools and Materials

Before you start, make sure you have the following tools and supplies:

• Level (4-foot)
• Hammer
• Utility knife
• Tape measure
• Caulk gun with silicone caulk
• Roofing nails (1.5-inch galvanized)
• Window flashing tape
• Shims
• Step ladder

Step 2: Prepare the Opening

1. Cut the House Wrap:

   • Cut an "X" from corner to corner or a straight cut down the middle.
   • Fold the flaps of the house wrap into the opening.
   • Secure them with roofing nails or staples.

2. Trim the Top Corners:

   • Cut about 6 inches of house wrap at an angle in the top corners to allow for proper window installation.

Step 3: Apply Flashing Tape

1. Measure and Cut Flashing Tape:

   • Hold the flashing tape about 3-4 inches over the opening and mark where to cut.
   • Use a utility knife to cut the tape.

2. Install Flashing Tape:

   • Peel the backing and stick the tape into place, overlapping half onto the wall and half over the opening.
   • Cut up the sides of the window opening and fold the tape into the bottom of the opening.

3. Seal the Corners:

   • Cut additional pieces of flashing tape for the corners and apply them to ensure a good seal.

Step 4: Set the Window

1. Remove Protective Board:

   • Unscrew any boards holding the window in place before installation.

2. Apply Silicone Caulk:

   • Run a bead of caulk around the window opening, ensuring it stays within 0.5 to 1 inch from the edge.

3. Position the Window:

   • With a helper, place the window into the opening, starting with the bottom.
   • Adjust the window to ensure it is centered, level, and plumb.

Step 5: Secure the Window

1. Check Level and Plumb:

   • Use a level on the bottom and sides of the window.
   • Adjust if necessary to ensure it is straight.

2. Nail the Window:

   • Secure the window by nailing through the nailing flange using roofing nails.
   • Make sure nails are angled slightly away from the J-channel to prevent damage.

Step 6: Finalize Flashing

1. Seal the Top and Sides:

   • Apply more flashing tape, extending it about 3 inches above and below the window.

2. Finish with House Wrap:

   • Fold the house wrap over the window and trim as needed.
   • Apply flashing tape to cover any exposed corners.

Step 7: Insulate Inside

1. Insulate the Gap:

   • Use spray foam insulation or tuck fiberglass insulation into the gap around the window jam.

2. Prepare for Trim:

   • Ensure the window jam sticks out slightly to accommodate drywall and trim.
