How to Replace or Retrofit Windows

Window installation made easy.

Replacing your old windows is a good idea. Your new windows will be better built, including being better insulated, which means energy savings in your pocket.

Installation methods do vary, including the possibility of a retrofit window.

Normal installation or retrofit can both be accomplished with just some basic tools and a few hours to do the task. Put on the protective gear, making sure it is comfortable and in proper position, before starting the project.

Instructions

Removing Old Window

1. Cut away old paint and silicone from around the window trim with the utility knife.

2. Pry off the window trim with the crowbar. Pull out any nails with a hammer. If the trim is held on with screws, remove it with the cordless drill and screw bits.

3. Cut away any window insulation.

4. Remove any nails or screws that hold the window frame to the stud walls with the hammer or cordless drill and screw bits.

5. Pull the window out of the hole opening. Use a helper to reduce the chance of dropping the window and breaking the glass.

Installing New Window

1. Measure the hole opening width and height to make certain the new window will fit.

2. Place two wood shims in the bottom of the window opening. Lift your window into the opening and place on top of the wood shims.

3. Level the window in place while you install one stainless steel screw through each side of the window frame and into the wall studs.

4. Continue to level the window as you add more shims and screws to hold the window securely in place.

5. Insert backer rod insulation into the larger gaps between the window frame and wall studs. Spray non-expanding foam insulation into the smaller spaces to fill them in.

6. Set up the chop saw and 6 to 8 foot long table. Make the measurements for your trim with the tape measure.

7. Cut all corners at a 45 degree angle, so they fit together smoothly.

8. Nail the trim to the wall with 8 penny nails or use the cordless drill and more stainless steel screws.

9. Apply a bead of silicone to the window trim with the silicone gun and silicone. Let dry several hours.

Tips & Warnings

• Maneuvering the new window in place can be awkward, depending upon the size and weight of the window. That is why having a helper can save time and make the installation easier.
