Before replacing a window, consider how the windows are made, how they are installed and functioning thereof. Since there are so many different types of windows, you should know your options reset. A typical double-hung window can be replaced with a vinyl window made as introducing the new drive into the jambs. This is the most common and usually the option to change window easier, since you do not have to modify the outer wall surrounding the window.
Some windows have no separate jamb, and need to be removed completely. In that case, it is not possible replacement jamb to jamb. If the window is working properly, it is likely that the opening is square, and will be easier to install the replacement sale.
Replacing a window-1 (Figure 1) The existing window was removed so that the rough opening could accept the new window.
Determine whether it is preferable to install a new window jambs inside or remove everything and let the rough opening. If the jambs are intact, a revival of vinyl manufactured as jamb to jamb is the easiest option. However, if you are going to replace a window made to measure, it may be preferable to remove the entire window and reshape the rough opening to install a standard window. For our complete list of cities and suburbs that we cover check out our coverage areas page.
Browse the outer wall (ie, coating, plating, stucco) at the point where it joins the window. How difficult it will be to remove and replace the wall?
Measure the window replacement
Because vinyl windows made to measure can not be returned, it is very important that the steps you take are accurate. Most replacement windows are made of ¼ inch increments. Take measures so that the window fits best.
How to Replace a window 2 (Photo 2) The existing jambs were removed to be used later.
Make sure the end of the tape is not damaged and that the tape is read correctly. Take three measures side to side of the inner face of the window jambs. One near the top, one in the center and one near the bottom. Use the smallest of the three measures as window width replacement.
Measure frame diagonally in both directions. If the measurements are the same, the frame is square. Repeat for the vertical dimension, but this time measure from the inside of the top jamb to the sloped sill, a little beyond the point where the sill meets the windowsill. Retake the smallest of the three measures.
If you are going to change the whole window, remove the frame to see and measure the rough opening. Never assume that all windows are the same size. Make a sketch and number each opening separately so you can keep track of each series of measurements of the windows.
Remove the old windows and prepare the opening
If you are replacing a double-hung window with a vinyl window jamb manufactured as a jamb, you must remove the internal stops and the two racks. A wooden window has two sets of stops that keep the upper and lower racks into place (inside and outside), and a blind stop.
Carefully remove (or unscrew) internal buffers so that they can be reused. Cut the strings of the racks and remove the lower frame. Let falling counterweights framework; You not have to remove. If there were panels access, you can remove, remove and reinstall the weights such panels. Remove the blind stopper and remove the top rack.
With the flat bit, drill three holes on both sides of the side jambs, the head jamb and sill. Spray insulation to completely fill the voids, and remove by scraping any excess. Had putty or peeling old paint, remove it by scraping; then sand and paint the surface of the jambs.
Replacing a window
Replacing a window 3 (Photo 3) a filling ¾ inch thick at the bottom of the frame of the rough opening was added.
In this project (photo 1) A standard Windows replacement was used. The existing window, including jambs, took off for the rough opening could accept the new window. (Photo 2) both racks were removed to prevent breakage of glass, and the unit will result lighter and easier to handle. After removing the screws holding the frame jambs raw and cut the caulking between the window and lining, full frame retired.
To reduce the vertical dimension of the rough opening so that accepts the standard window, a rubber ¾ inch thick was added to the bottom frame of the rough opening (figure 3). The new landfill will be reviewed to check that was leveled.
Place the new window into the opening
Whether you go to replace the entire window or install a replacement jamb to jamb, if the lower horizontal surface of the opening is level, the new window will run correctly. If not, put a wedge between the rough opening and the bottom of the frame of the new window, or in case of a replacement jamb to jamb between the bottom of the existing framework and the bottom of the unit replacement.
Place the new window into the prepared opening and center from one side to another. Check that the sill is level, and that the sides are plumb.
How to frame a window
To frame a window (the leveled horizontal surfaces, vertical surfaces to lead and both measures equal diagonals), you may need to put a wedge. Usually in any space of ¼ inch or less you can wear a fit. If the space is larger, you must install a piece of padding to reduce the width to a dimension that can put a wedge. Cedar shims or composite are always used in pairs, with angular sides facing each other. A wedge is inserted from the outside, the other from within.
How to Replace a 4. (photo 4) If the window jamb is plumb, remove the screws and skids, and start again.
In the jambs, shims should be used wherever the new window is bolted to the frame (or jamb). Usually holes are predrilled jambs in replacement windows. Shims to adjust and prevent the sides of the window to bow when the windows are permanently fixed. Verify that the jambs are plumb before and after inserting shims and fix the window. If the jamb is plumb, remove the screws and skids, and start again (photo 4).
Replacing a window of 5 (photo 5) Fill any space surrounding the perimeter with loose insulation.
To fit the bottom of the opening, place the shims to about 1 inch from either end and near the center of the opening. You may need to hold slightly the side of the window, the head with a wood screw 2 inches. Insert the screw just enough so that the window can open and close. Check diagonal measurements of the window to make sure they are equal. After checking, the window is square, and will operate and close normally.
Never put a wedge at the top of a window or hold the frame. The windows are not structural, and any type of restraint to the top of the rough opening could cause the window to break and / or that this malfunction.
Replacing a window 6 (picture 6) Slide the top behind the flashing in the top of the window.
Completed the task of changing a window
Once the window is driveway, securely and functioning properly, flush cut and remove the excess shims. Fill any space surrounding the perimeter with loose insulation (5).
For this project to change was necessary to cut a window and drive a new brick mold around the perimeter of the new window to close the space between the window and the coating. The top section slid behind the flashing at the top of the window, and then the perimeter (photo 6) enmasilló.
Replacing a window 7 (figure 7) Install the new screen and removable tapes and verify that it works correctly.
Finally, the new wire mesh and removable racks were installed, and then make a final check of proper functioning, work (photo 7) was concluded.

Tools you will need to change a window
Although each window replacement project is different, you need some of the following tools, or all:
