Do-it-yourself window replacement is an interesting project and less expensive compared to when you hire a Window installer. If you have an old house with extremely old windows and doors, it is best to replace them before they either break or their hinges come off. Additionally, it is not safe to have old doors and windows as anyone can break into your house just because the doors and windows are not strong enough. However, it is important to note that older windows were much different from the windows of today. Wndows today, are much like self-contained units that can be easily inserted into openings in the wall created for them. In the olden times, windows were installed in pieces, so you will have to take out each of these pieces of window if you want to replace them.
One of the most important thing to consider when replacing your window is to always get a replacement window that will fit right. If you purchase a window that leaves gaps, the entire purpose of the replacement will be defeated. Also, never take out the old window before purchasing the new window.
Measure the Window
Measure the height, width and thickness of the window with a measuring tape. Start at the window jamb which is the widest point your window is sitting. Then measure the length from this opening to the top, to the middle and then to the bottom. Subtract 1/4 inch from the smallest measurements you have. Ideally, this will give you the width of your window. Measure the height again from the middle of the window on both side and then subtract a 1/4 inch from the smaller number again. This is will give you the height of your window. You can now order your window with these numbers.
Remove the Old Window
You will first have to remove the trims on the sides of the window to be able to take off the window. These are usually made of clay to steady and hold the windows. Use a hammer or a flat bar to loosen off the trims. After removing the trim, begin to pull the bottom sash out. At times, it is connected to the wall by a weight attached to a small chain. To remove the weights, cut the chain and then remove the pieces that are holding the top of the sash. Remove all the pieces carefully to leave a clean hole for the new window.
Install the New Window
Apply some force to push the window in place. The bottom part of the window goes into the jamb. Ideally, the trim should allow the window to remain in place. Make sure the length and the width of the window should be in level. You can use a level bar to make sure of this. Once the windows are leveled, set the window in place with the screws. Caulk around the window with a caulking gun and trim the caulking to give a clean finish.
