Common Window Replacement Mistakes to Avoid

The proper installation of your home window is no easy feat. If not done right, it can often lead to unforeseen problems in the future. It usually takes experience, precision, and expertise to install new windows safely. One of the most common mistakes is attempting to install a window without the proper experience and practical knowledge.

While you may know where to look to determine that your windows need replacement, problems are likely to arise if you choose to replace them on your own and you don’t have prior experience. Once you determine that your windows need replacing, it’s crucial that you find a reputable and experienced local window installer to help install your new window and avoid making costly mistakes. In this article, we’ll look at some of the most common mistakes to avoid when replacing your window:


1.  Purchasing the Wrong Size Jamb Windows

In case of a full-frame window replacement, you’ll most likely order windows with attached jambs. It’s crucial to consider the jamb’s width, especially if you are responsible for measuring and ordering the windows. Most windows will usually have the same jamb depth, but there are occasions where you’ll need to consider other factors. For instance, if the finished interior surface is thicker than the drywall, you may need a wider jamb.

Since jambs are the main vertical components of your window frame that ensure a perfect fit, you must be sure to do the calculations before ordering the window. Also, add the width of the jambs if the finished interior walls will be plastered.

2.  Installing Windows at Different Levels

Full-frame window replacement involves pocketing the window into an often rough opening. The window will thus need to be effectively secured to the opening. Always ascertain that your window is level, centered, square and plumb before securing it. You may also need to add shims to get the window positioned right.

Other than matching profiles, you’ll also want to consider placing your windows appropriately to keep clean lines across the home. This can be a problem in window replacement only if you ordered wrong-size windows or unknowingly try to replace incorrectly installed window replacements.

3.  Using the Wrong Spray Foam

Bad spray foam can be two-fold. Either you used the wrong foam, or you ended up with the entire window perimeter covered with foam. You should only use a non-expanding spray foam sealant since expanding spray foam could bow wooden jambs or distort your window’s frame shape.

You might consider filling the entire window cavity with foam, but this means water cannot escape. Some water that finds its way near your window needs a way to flow out, and foam can prevent this from causing unwanted water build-up.

4.  Not Following Manufacturer’s Directions

When you’re installing windows, remember to read the manufacturer’s instructions. While most instructions will tend to be quite similar, each manufacturer will often have some unique requirements and best practices. Follow the instructions provided to get the most utility from your window. Following instructions will also prevent you from violating the manufacturer’s warranty conditions.
