Windows FAQs, answered by experts

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

The cost of window installation depends on several factors, including the window type, size, and frame material. Labor rates, the need for custom sizing, and any required structural modifications will also influence the final price.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

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.
