"Andrea was great to work with and she wasn't pushy like a few others I got quotes from. She knew the product and was able to answer questions. Brett and Aurelio was great when they came to install the windows. They explained how the process was going to go and how long it should take. Great group of people and would highly recommend them."

Windows FAQs, answered by experts

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.

On average, hurricane windows last between 20 and 30 years. But some windows only last 10 years, while others can last 50 years or longer. Vinyl hurricane windows have a shorter lifespan than aluminum, so invest in high-quality hurricane windows and properly maintain them to get the most out of your investment. 

The maximum protruding distance allowed for a bay window is determined by its flank angles. 30-degree flanks can extend about 13 to 14 inches. If the angle is 45 degrees or larger, then the bay window can stick out about 19 inches. If the window extends too far out, it would cause structural instability and safety concerns.

Hopper windows aren’t flawless when it comes to keeping rain and debris out of your house because if there’s wind pushing the precipitation, it could easily get in through the open space. On top of that, hopper windows aren’t potential escape routes the way regular windows are in case of a fire or emergency. If that’s a priority or need, it’s something to consider when choosing a window type.

If your windows weren’t manufactured with a retaining clip to receive muntins and hold them in place, you should contact a window company near you to add them for you. A professional will bond the muntins directly to the glass to hold them in place, and they’ll make sure the edges line up nicely with your window frames. If your window does have retaining clips to hold muntins in place, you can just pop the muntins into the clips.
