If you are no longer interested in your double hung windows and want to replace them with awning windows instead, simply follow these instructions to give your home a new feel. Before getting started, it will be helpful to have a few items handy.

Step 1 – Removing the Old Double Hung Window

Take out the window by first getting rid of the interior trim with a pry bar. Work one length, making sure not to peel off the wall paint. Using the utility knife along the trim helps with this as it comes off the wall. You will then need to take strip away the exterior trim, as well as the sidings. If the sidings are vinyl rather than wood paneling, use the zip tool to remove them. Screws and nails on the frame edges also need to be removed. Ejecting the window then becomes possible by pulling it out. Having someone on the other side pushing is also helpful.

Step 2 – Getting Ready for the New Awning Window

Now that the double hung window is gone, you must get the new space properly prepared for its replacement. Make sure the hole is clean by scraping off any remaining putty and clearing away debris. Check that the awning window is measured accurately and that all edges, both on the window and the space, are level. You must also take into account the health of surrounding wood frame. If any rot, erosion, or damage is visible it may compromise the stability of the window. 

Step 3 – Inserting the Window

This step begins by nailing the window flashing around the rough frame opening. Each piece should be overlapped onto the next one. The final piece can be caulked directly to the frame. At this point it would be useful to check your work by putting the window into the crude opening. Any discrepancies in plumb and level can be alleviated by strategically incorporating the wood shims. Place the window in its final position by running caulking all along the inside of the interior opening. Secure it by then nailing the mounting fin to the rough frame.

Step 4 – Finishing Touches

Once the window in place the new look should be taking shape. Finish the project off by making any necessary adjustments or adding finishes or trim pieces.

Step 5 – Enjoying the New Awning

Awning windows are perfect for breezy ventilation, as well as maintaining indoor privacy. If you decide to place a screen, it will have to be on the inside, which may attract dirt and dust that will land on your floor, so keeping it clean is important.  Also make sure there is enough clearance for plants, as some awnings open wide.
