Replacing your old windows with new energy-efficient windows can make a remarkable improvement in your home or in any room for that matter. An Awning window provides light and opens outward to catch a breeze making it a great choice for practically any room. The sash on most awning windows closes tightly against the frame, making it a better choice than the traditional double-hung unit for air infiltration. A single large awning window is often used in a kitchen or over a sink, pairs of them often flank other windows or are arranged together over large patio doors. When you remodel a basement, replacing an old awning window, will go a long way toward making any space lighter and brighter! A window contractor will charge around $425 to install a 3-foot by 4-foot awning window which should include labor and materials. However, if you have carpentry skills and tools, you can do the job yourself for about $250. Make sure you plan to do the project so you remove the old windows and immediately install the replacements. If not you may be inviting a variety of animals inside your home!
