Replacing windows is a home improvement project to do if existing windows are not energy efficient. This is a common option for homeowners wishing to reduce energy costs. However, a standard or custom replacement window can be ordered at a home improvement store or from a local window company – like Home Exterior Systems in Houston.

Measure the Window

Proper measurements are required before beginning any window replacement project. A measurement is needed of the width and height of the existing window opening. This will need to be done from inside the house, as replacement windows are not installed from the outside. Windows need to be measured from the jamb on one side to the jamb on the other; measure from the inside of each jamb to obtain the width. Make sure to get a measurement at the top, the middle, and the bottom. The smallest measurement will need to be used. The height of the window is measured from the inside top of the sill to the inside of the top jamb. Record each measurement to use later when ordering the new replacement windows.

Remove Old Window

Remove the decorative trim around the perimeter of the window by using a pry bar. Remove the stops on each of the sashes. This can be done with a screwdriver or by using the pry bar. Removing the stops will need to be done carefully to limit damage to the window opening. Save the stops because they can be used when the new window is ready to be installed. The sash should be removed next. Look to see if the window has a sash cord or rope that will need to be cut. The outside sash will then need to be pulled down before taking off the parting beads. Take off the outside sash, but make sure to leave the stops in place.

Clean Window Opening

Scrape off old paint and take off any pieces of trim that surround the window opening. The jambs will need to be examined for any holes and splintered wood. Sand the wood smooth and fill holes by using wood putty. Pieces of fiberglass insulation can also be used as this will help with heat loss. Clean using a vacuum or brush to remove any debris from the sill.

Dry-Fit New Window

Place the new window in the opening to test the fit. This will determine if shims or other measures are needed when securing the window. Look on each side of the window to locate the mounting holes. Remove the window and set it aside.

Prepare Window Frame

Apply a bead of silicone caulk to the perimeter of the window frame. The caulk helps to weatherproof the window by keeping out air. Set the header piece on top of the replacement window and apply caulk across the top.

Install the Window

Set the new replacement window in the window frame. Check with a level. Square the window by placing shims in-between the window and the frame. The shims should stick out at three to four inches. Insert the mounting screws and tighten with a power drill. There may be gaps between the window and the frame. These gaps can easily be filled by using spray foam insulation. Open and then close the window to test its operation. Adjust the screws if the sashes are difficult to open. The last step is to knock out the shims.
