How to Replace Home Windows: A Guide

Do you want to replace your windows in your home? Sometimes it is tough to find the right crew to help you with home projects. 

You’ve got to find someone that works with your schedule and that is consistent. Finding outside help can be a job all of its own.

Instead of outsourcing the work, why not do it yourself? 

There are numerous reasons why you should replace home windows yourself, one of which is to save money.

Not sure how to replace home windows? Here, we’ll give you the tips and tricks you need to know to get started! Keep reading to learn more.

Know the Window 

The first step to replacing home windows is to ensure you have the right information from the get-go. Though window replacement seems basic, there are some technical things to know. There are three different types of replacement windows:

  • Sash kits, which give old frames new parts that are moveable
  • Insert replacements, which fits into the current opening
  • Full-frame units, which are new, complete frames

Know which one you’re looking for before you get started. This will save you time and money in the long-run when learning how to replace home windows. 

Next, grab your tape measure to calculate the dimensions of the window. To measure the windows, first, run the tape measure horizontally across the top, middle, and bottom of the window. Write down the smallest of these three measurements to ensure the best fit. 

You’ll repeat this process going vertically down the window. Measure the right, middle, and left sides, then record the smallest number. 

The last measurements to grab are the window diagonals. These need to be the same, if they’re more than 1/4 inch off, you may need to contact a pro. 

Removing Old Pieces

Now that you’ve got your initial measurements, it’s time to start ripping away remnants of the old window. Start by doing these things:

  • Vacuum the window opening
  • Remove the window sash
  • Pry off any jamb liners
  • Take out sash weights, if any remain

You want to make sure any pieces of your old window that can be removed are gone before installing the new one. This will provide a more stable and clean installation. 

Prepare the Window Opening

To start, scrape off any old glue, paint, or goo from the window frame. Then, sand down any rough patches of wood. This is important to ensure there are no gaps later when you add the window. 

Also, be sure to spray foam into the opening before caulking any open areas in the frame. Caulking helps eliminate space between your window and window frame, reducing drafts. 

When you prepare the window opening, you’ll also have a chance to see any warped areas of the frame. Use this time as an inspection.

Install the Window

Stand inside the room whose window you’re replacing. Set the bottom of the window on the bottom of the frame and slowly begin to push it into the window cavity. 

Then, use a drill to loosely secure the window. Make any necessary adjustments. When the window is a snug fit, drill the window fully in place. 

Post-Work

After installing the window, you’ll need to caulk and paint the frame. By doing this, you’re examining all areas of the window by closely working more with it. 

To be most energy-efficient, work on cleaning double glazed windows for the best results.
