How to Replace Your Windows

3/22/2016 4:11:37 PM

Tired of your leaky, cracking, hard-to-open windows? It’s time to replace them. Your budget may be tight, or you may simply want to save money on the installation by doing it yourself. If you’re an avid do-it-yourselfer with handyman experience, you may be able to complete the job yourself with the help of an equally knowledgeable friend. Otherwise, in almost every situation best to hire a professional.

DIY Window Replacement

Before you decide taking the DIY route is right for you, consider all the steps involved:

Take Window Measurements

Measure the height and width in three different places so you know what size window to buy. The decision to replace the frame or reuse it with the new window determines where you should take your measurements from.

Remove the Old Window

The procedure for removing a window depends on the type of windows you have. For double-hung windows, it’s a fairly straightforward process of taking out the inner sash, removing the inside stop pieces and removing the outside sash. You then need to clean up the window frame, assuming you’re keeping it, and prepare it for new window installation.

If the frame is rotting, you’ll need to replace it along with any damaged surrounding structure. In this case, it’s best to stop what you’re doing and contact a professional for help.

Install the New Window

With the preliminary work out of the way, now you can focus on the actual installation process:
  • Caulk the inner portion of the outside stops on the window jambs.
  • If you plan to use a window expander, secure it in place with caulk now.
  • Center the inside and outside sashes in the frame. Slide the bumper stops over into the middle of the frame until four mounting holes become visible.
  • Shim each window pane if necessary. Check for plumb, level installation with a leveler.
  • Fasten four screws into the mounting holes.
  • Expand the window header to create a tight seal between the window and frame.
  • Check for gaps around the window and correct them with adjustment screws.
  • Caulk the inside of the window.
  • Reattach the inside stops.

Benefits of Professional Window Installation

If the prospect of installing your own window is overwhelming, enjoy the many benefits of professional window installation in place of the DIY route:

Better Materials

The windows sold at home improvement stores are not nearly as high quality as windows available from premium Weather Shield dealers. Better materials available from a professional helps you get the most from your window replacement project.

Superior Installation

You can make guesses during the installation, or you can enjoy the peace of mind that comes with trusting a professional with years of experience replacing windows just like yours.


Most manufacturers only honor warranties if a professional installs the windows. If something goes wrong, your efforts to save money on a DIY installation could backfire.
