What Should You Know Before Replacing Your Own Windows?

Even if you do have the funds to spend on your window project, you need the expertise as well. You may want to start with insert replacement windows if this is your first time, as these slip right into place. Insert replacement windows also require less deconstruction, in that there’s no need to remove your trim or window frame. 

The simplicity of this project means you can do it relatively quickly and have your new windows up and ready to admire by the time the weekend ends. 

If you have tinkered around with window work before, then you may be interested in a full-frame replacement window project. As the name implies, this job does involve you taking out both the window frame and the trim while installing the new window. Since it’s more complex, you could pay more for the materials to do this job yourself. 

Also, it’s going to be more time-consuming. For each window, you have to install on your home’s main floor (the one that’s ground level), expect to work for at least four hours. It may even take you six hours. 

You’ll also have to add considerably more time to your project when the time comes to install the windows on the home’s upper floors. The only exception would be if you have a single-story house. 

How do you choose between insert windows or full-frame windows? Don’t just pick one type based on cost and time intensiveness. If your windows are in pretty good shape, with frames that haven’t decayed or worn down, then insert windows are a smart choice for you.

If a.) your trim no longer matches your home, b.) it’s worn down or rotted, or c.) you’re buying a bigger window or one in a different shape, then you need a full-frame window replacement. 

What Do You Do with the Old Windows?

If you do opt for a full-frame window replacement, you’re going to have a lot of old windows and trim to deal with. While normally, your window installation company will take care of the removal of these parts, since you went the DIY route, that onus is now on you.

This isn’t necessarily a bad thing, as old window parts can be useful in a lot of ways. You can hold onto the wood and reconfigure it for other household projects. You may also recycle the parts, including the frames and sometimes even the window glass.

However, if recycling isn’t an option, look for a local waste transfer station. Typically this is where contractors dispose of their old windows and other debris.

Should You Choose DIY Window Replacement or Let the Pros Do It?

Replacing your windows is a big job. If it’s done incorrectly, your home could be blemished. Even worse, you’ll have to turn around in a few years and pay for new windows all over again. Thus, deciding whether to do this yourself or let a professional handle it is a decision that shouldn’t be taken lightly.

If your window frames are in good enough shape that you only need insert replacement windows, then you can probably save yourself the money and do this project on your own. For full-frame replacement windows, we recommend tackling this yourself if you’re completely comfortable with all facets of the job.

If you just spent a fortune on new windows, such as wooden windows or those from Marvin or Andersen, then it might be worth letting a pro step in. They will handle your new windows with the care they need. The team can also ensure that installation will be done right the first time, maintaining the integrity of your pricy new windows. 


Replacing windows is a job normally reserved for window companies, but many homeowners have begun tackling this project themselves. You can do so as well, saving some money in the process. After all, instead of paying for labor and installation, you only have to buy your windows and related tools.

If you’re seriously contemplating a DIY window replacement, the information in this article should act as a great starting point. Good luck!
