How To Replace A Window In Your Home

Posted on: 17 October 2016

Replacing your windows can help add curb appeal to your home by adding beauty both with the window, as well as the new surrounding molding. Those new windows can also help save you money if they are energy efficient; helping to keep drafts out and your heat/air conditioning inside your home where it belongs. Replacing all of your windows at the same time may not be in your budget, maybe not even replacing a few at a time. Even if you have to replace them one at a time, it's better than none at all. Replace those old drafty windows and invest in new windows. If you're handy, you can replace your windows yourself. See below for instructions and tips. 

Here's What You'll Need:

  • Crowbar
  • Level
  • Hammer
  • Window
  • Foam insulation
  • Caulk/caulk gun
  • Shims
  • Power drill
  • Galvanized screws
  • New window


  1. First, you'll need to begin taking out the old window. To help control the amount of debris in your home, use tarps or drop cloths on the floor around the window. Take off the trim on the inside of your home and on the outside, the window sill (if you have one) using a crowbar and hammer, then carefully take out the window.
  2. You should now have an open area where the old window used to be. You should be able to see the studs in the wall and the header. Use the level to ensure they are level, and use a square to be sure they are all square. If they are out of square of unlevel, use your hammer and some nails to help level it out and make it square.
  3. Next, add felt wrap around the window opening to help keep moisture out. Use nails to help hold it in place. 
  4. You can now begin to put the new window in place from the outside of the house, by pushing it up into the top of the frame and making sure it's in place at the top, then carefully press it in place along the sides and finally at the bottom. This job may require a second person on the inside of the house to help you. Once you have the window in place, level and square, use the galvanized screws to hold it securely in place.
  5. Add insulation around the window to help keep moisture out and to keep your heat/air inside your home. Use foam insulation that expands to ensure you have insulated the window thoroughly. Once the insulation is dry, you can use a utility knife to cut off any excess.
  6. Now is the time you can add window trim around the exterior of your home. Use vinyl, wood, or cement board around your window. Wood and cement board will both need to be primed and painted, vinyl is a little easier to maintain, as it doesn't need to be painted.
  7. Finally, add the trim and sill back to the interior of your home around your window. If the window was the same size, you can reuse the trim you had in place with your old window.

Replacing your windows can add beauty to your home and make it more energy efficient, making the cost of those replacement windows well worth it. Replace your windows yourself, or have them installed by a professional to ensure they are installed correctly if you aren't sure about doing the job yourself.


Expanding Families Means Expanding Homes: Addition Building 101

When my wife and I found out we were expecting a baby, I knew that our small starter home wasn't going to be big enough for us to raise a family. We loved the house and the neighborhood though, so we didn't want to move. That's when I decided to just build an addition. From planning to construction, the process was kind of intimidating. I didn't know what to expect along the way, and that made it more difficult. I created this site to detail our experience with the construction of the addition. I hope it helps you to prepare for your next home construction project.
