"The windows were manufactured earlier than we expected and we were promptly contacted about installation. Although we were told the installation was scheduled for two days, the four man crew that arrived was able to finish in a single day! Each window was installed with the same consistency in quality and efficiency. Furthermore, the crew did an excellent job protecting our floors and furnishings in every room. When it comes to evaluating the installation crew, we couldn't be happier. Regarding price, we probably paid more than we should, but that's on us. We advise getting several other quotes first and then get Castle's quote. This will definitely help in your negotiating. The windows have definitely helped to eliminate draftiness in our home and helped to maintain a consistent temperature."

Window Treatments questions, answered by experts

Mulled windows are no less efficient than individual windows, provided the wall opening is the same size. Larger wall openings filled with glass will always reduce overall energy efficiency, as glass transmits heat more readily than a solid wall. If the windows that are mulled together have the same square footage as individual windows, you might actually see a small decrease in your electric bills, as mulled windows let in more natural light that can reduce interior lighting costs.

Storm windows have about the same life span as standard windows—between 20 and 30 years. Vinyl and wood storm windows last longer than aluminum, but they all fall within that life span range. Of course, how long your storm windows last will depend on how much severe weather they see. Direct impacts, in particular, can quickly reduce how long your storm windows last.

Window replacement is typically always worth the cost, both from a money-saving standpoint and a comfort standpoint. If your windows are older and significantly damaged, a window replacement can actually save you money in the long term by improving energy efficiency. If your windows aren’t up to code, you may not really have a choice. 

The most likely cause of smearing or streaking after cleaning your windows is residue left on the glass from the cleaner you’re using. Consider diluting the solution and cleaning them again, or use old newspaper to dry the windows after cleaning, as this will soak up any residual material. Additionally, aim to clean your windows on a cool, cloudy day, as cleaners will dry more quickly on the glass if it’s hot and sunny, promoting streaking.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.
