Removing the Existing Crank Out Window

Begin by carefully removing any window treatments or screens from the window frame. This ensures unobstructed access and prevents damage during the removal process. Next, open the crank out window to its fullest extent to expose the hardware and sash components.

Locate and remove the screws securing the sash to the frame. These are typically found along the sides of the window where the sash meets the frame. Use a screwdriver or drill with the appropriate bit to avoid stripping screws. Once the screws are removed, gently lift the sash away from the frame. If the sash is stuck, use a plastic putty knife to carefully pry it loose without damaging the frame or glass.

After removing the sash, examine the hinges and crank mechanism attached to the frame. Unscrew these components and store them if they are to be reused or dispose of them if they are damaged or incompatible with the new window. Finally, clean the frame thoroughly, removing any old caulk, dirt, or debris to prepare for the installation of the replacement window.

Preparing the Window Frame for Installation

Proper preparation of the window frame is critical for a secure and weather-tight installation. Inspect the frame for any signs of rot, damage, or warping. Repair or replace any compromised sections to ensure structural integrity.

Apply a high-quality, exterior-grade sealant or caulk around the perimeter of the frame to create a waterproof barrier. This step prevents water infiltration that can lead to mold, rot, or damage to the surrounding wall structure.

Check the frame’s dimensions against the new crank out window to confirm a proper fit. The new unit should fit snugly without forcing, allowing space only for necessary shims to ensure the window is level and plumb.

Use shims to adjust the frame as needed, placing them at the sill and sides. Verify the frame is square by measuring diagonally from corner to corner; the measurements should be equal. Adjust shims accordingly until the frame is perfectly square.

Installing the Replacement Crank Out Window

Position the new window carefully into the prepared frame. Ensure the window sits evenly and the crank mechanism is oriented correctly for operation. Before securing the window, double-check that the window opens and closes smoothly without binding or resistance.

Secure the window by fastening it through the pre-drilled holes in the frame using corrosion-resistant screws. Tighten screws incrementally, alternating between sides to maintain even pressure and prevent warping.

After the window is securely fastened, install the interior and exterior trim to cover gaps and provide a finished appearance. Use caulk around the trim edges to seal any remaining openings against air and water infiltration.

Test the crank mechanism multiple times to confirm smooth operation. Lubricate the moving parts if necessary with a silicone-based lubricant to enhance performance and longevity.
