What Are the Most Common Window Installation Mistakes?

Posted on Posted in Custom Glass, Residential Glass, Window Repair, Window Replacement

While there are many home renovations that homeowners can complete with a little DIY know-how, window installation isn’t one of them. When you need to install replacement windows—or when you’re constructing a new home or undergoing exterior renovations—you’ll want to call the pros to install your windows. However, even professional handymen and other installers can make mistakes. That’s why it’s best to go with window replacement experts like the team at Crandell Glass & Aluminum, LLC. We not only work to complete each job right the first time, we also fix the following window installation mistakes.

Mistake #1: Incorrect Measurements

The most common mistake we see is incorrect measurements. You may be surprised how many windows are installed that aren’t actually the right fit for a space. Another issue is that homeowners often assume most window openings adhere to standard sizes. However, there are a lot of factors to consider when it comes to window size. For example, older homes may feature windows outside of the current standards for new home constructions. In addition, conditions like dry rot can create a larger hole that needs to be filled in the window opening.

Mistake #2: Failing to Create a Backslope

Windowsills should be designed to stand up to weather. That means that a backslope should be part of the windowsill design. A back dam should also be incorporated to avoid unwanted moisture from entering the home. Even if you are installing a replacement window in an existing opening, it is essential to check for proper moisture diversion. If you aren’t sure what to look for, our professional installers can help. We will ensure that the window opening is adequately prepared and measured before placing your new window.

Mistake #3: Poor Flashing Adherence

Small details make a big difference when it comes to window installation. Therefore, big problems can arise from something as simple as poor flashing tape adherence. When installing flashing tape and membranes over the weather-resistant barrier in the window opening, all moisture, dust, and debris should be wiped away to create a firm, tight seal. In addition, the right flashing tape should be selected for the surrounding environment. Some flashing adhesives do not perform correctly in cold weather or humid conditions. This is, again, another advantage of professional installation. Our team will not only recommend the right replacement windows for your home, but we will select the appropriate installation materials to keep the window securely in place.

Mistake #4: Correcting Gaps with Spray Foam

In some DIY window installations, the window frame or the window itself may become damaged by the addition of spray foam. While spray foam may be used to seal the window in place, it must be selected carefully. Expanding spray foam may crack or split wood in the window frame or bend the window itself. In addition, spray foam can be difficult to work with and easily create a mess on unfinished or untreated wood. Therefore, it should not be a fallback for correcting installation mistakes.
