Why Proper Replacement Window Installation Is So Important

Andersen Certified Installer Badge

Your home could have the best windows in the world but if they are not installed correctly, they will not perform correctly. Cracks, rotting, and mold buildup are only a few signs that your windows were poorly installed, and now is the time to call in the experts. All-Weather Windows, Doors & Siding has been installing windows throughout the Kansas City metro for more than 30 years and we have witnessed, firsthand, the importance of quality window installation. 

Signs of a Bad Window Installation

There are many signs of poor window installation. Unfortunately, many times they don’t show up until your windows have been in place for a year or more. Here are the most common issues:


Condensation between the window panes is one of the first things homeowners notice after having windows installed improperly. It’s one of the top reasons people replace their windows. Windows are designed to complement the vapor barrier created by your walls. The goal is to prevent moisture from passing through from the outside around the window frame. But if proper steps are not followed during the installation process, vapor will condense on cold surfaces between the frame and the wall. Where there is condensation (moisture), rotting will follow. People think condensation is a problem with the window itself, but 9 times out of 10, it is the result of poor installation. 

With All-Weather, you won’t have to worry about rot, mold, and mildew in your home. Properly installed windows can eliminate these health risks and improve your home’s indoor air quality. Never settle for anything less than professionally installed windows!

High Energy Bills 

Professional window installation will reduce heating costs in winter and air conditioning costs in summer. If your energy bills are not decreasing, or even worse, increasing, your windows probably weren’t installed properly. Your wall’s air barrier is critical to keeping your home snug. Any break in this barrier is a potential area for heat exchange – in the winter your heat will seep out and in the summer, the heat will seep in. Even tiny cracks around the window frame can lead to air infiltration and substantial heat and energy loss. Add this up over years and you’re looking at hundreds or thousands of dollars in energy loss and higher bills. 


One of the main purposes of windows is to keep out harsh weather. Sure, we also want them to let in sunlight and allow us to have a nice view, but those are all secondary reasons to have windows. Proper window installation will create a continuous water barrier between the window and the wall keeping moisture from rain and snow outside.  Even the smallest gap or crack will grow to be a big problem. Mold, rot, and if left untreated, even structural damage can occur severely affecting your property value, not to mention your comfort level. With All-Weather’s experience and unique weatherproofing installation techniques, your property will be as weather-tight as possible. 

We Are Andersen Certified Window Installers 

Most window and door installers in Kansas City are trained on the job by other installers. While this is not the best way, it is the way it has been done for decades. Because we are on the service side of this industry, we have learned that most of the issues that people have with their windows and doors are installation-related. Most times the failure of the product could have been prevented had the window installer been properly trained. At All-Weather, all of our installers are Andersen Certified Installers.
