"We had a 35 year old solarium in great need of repair. The project was complex and difficult, but Wayne had the skills and expertise to replace six large windows and rebuild the solarium. It was a challenging project, and Wayne did an exceptional job. Our "new" solarium adds greatly to the value of our house. Wayne knows windows and doors and he gets five stars from us! Mary Ross"

"Dustin C. @ DaBella Boise helped us choose the right windows for our application and personally monitored progress from order to completion. The finished product looks great, but the best part is instantly seeing and feeling the difference between modern tech vs. 40y old aluminum framed windows. No more drafts or condensation! Thanks DaBella!"

Windows FAQs, answered by experts

Installing bifold windows can take anywhere from three or four hours to several days. Smaller bifold windows that open vertically and fit inside your existing wall opening should take just a few hours and no longer than a day. Larger bifold windows, especially wider ones, may require structural work before your professional can install the window. The installation could take two to three days, depending on how much work your wall needs.

The differences between a bay window versus a bow window involve the number of individual windows and the angle at which both windows extend from the home. A bow window has four to six individual windows that form a curve outside the exterior wall. A bay window usually has two small windows on the edges that angle outward from the exterior wall and a large window in the middle that’s parallel to the home’s exterior wall.

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.

Most modern egress windows installed in basements open outward into a window well, although some older homes have in-swing windows. Egress windows, like casement windows used in other parts of the home, such as bedrooms and bathrooms, may open inward, and these windows are often larger than outward-opening windows.

Most windows last between 15 and 30 years. The exact life span depends on a few things, including the frame material, the quality and type of glass, the weather in your area, whether or not the window is installed properly, and more. You can always speak with a window professional about whether or not it’s time to replace your windows or if repairs would be more affordable. You’ll need to consider the cost of replacing your windows, the cost of repair, and the longevity of each solution.
