Preparing for Window Installation

Before diving into the installation, preparation is key. Gather your materials, including the Viking Arm®, and ensure that your workspace is organized and that the window opening is clean and free from debris.

Materials Needed:

  • Viking Arm®
  • New window
  • Level
  • Shims
  • Screws and a power drill
  • Caulking and weatherproofing materials

Tip: Measuring the window opening twice before installation can prevent unnecessary adjustments later.

Step-by-step window installation process

1. Positioning the window

Positioning is critical in window installation, and the Viking Arm® simplifies this task considerably. Start by placing the window into the opening. If you’re working alone, the Viking Arm® will help support the weight of the window, allowing you to position it correctly without straining.

  • Action: Place the Viking Arm® under the window and/or the side, adjusting it gently to elevate the frame precisely into the desired position.

2. Centering and leveling

Once the window is roughly positioned, you’ll need to center and level it accurately. Use the Viking Arm® to make fine adjustments, ensuring that all sides are equally balanced.

  • Action: Check the leveling with a spirit level or laser and make micro-adjustments using the Viking Arm®. This step is crucial for the overall operation and aesthetic of the window.

3. Securing the window

With the window perfectly positioned and leveled, it’s time to secure it permanently. Insert shims on the sides to maintain alignment during the fastening process.

  • Action: Use a power drill to screw the window into the frame. The Viking Arm® will hold the window steady, minimizing any potential movement or misalignment.

Tip: Ensure that screws are placed securely without over-tightening, which can warp the frame.

Finalizing the installation

Once the window is secured, ensure the following finishing touches are completed:

1. Insulating and sealing

Proper insulation will impact the window’s energy efficiency. Apply caulk around the perimeter of the window frame to seal any gaps from air and moisture.

  • Action: Press caulking firmly into all crevices, ensuring a smooth, even finish.

2. Double-checking alignment

Do a final check to ensure that the window opens and closes smoothly without any obstructions. The initial precision provided by the Viking Arm® often ensures no further adjustments are necessary.

3. Clean-up and inspection

After installation, ensure the area is clean and inspect the window for any visible imperfections or misfits.

Tip: Take a moment to test the window. Check locks, handles, and any additional features to confirm they are functioning correctly.
