Windows questions, answered by experts

Double-pane windows increase your home’s energy efficiency, leading to lower energy bills and more comfortable temperatures inside. They also dramatically reduce noise from outside compared to single-pane windows, so you’ll notice your home is significantly quieter once you’ve installed double-pane windows. If you’re replacing your windows, the initial investment in double-pane styles can be well worth the up-front cost.

In addition to protecting your home from costly storm damage, storm windows increase your home's value if you live in an area that’s prone to severe weather. Storm windows offer about an 80% return on investment (ROI). Therefore, if you install $10,000 worth of storm windows, you can expect to get around $8,000 back if you sell your home within a few years of installation. Additionally, highly hurricane-prone areas, like the Florida coast, offer even higher returns, with ROIs on storm windows reaching up to 86%.

In addition to window well covers or bars, you can take a few more steps to boost basement window security. Try motion-activated lighting; it scares off potential intruders by lighting up when someone gets too close. Strengthening your window glass with impact-resistant security film can also deter forced entry. A dependable home security system with window sensors and cameras offers real-time monitoring and alerts for added protection. Lastly, fostering good relationships with neighbors can establish a supportive community watch network, enhancing your home's safety.

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

You will need about half of a caulking cartridge to caulk one window. The average home has eight to 10 windows, so you would need about 4 or 5 cartridges to caulk every window in an average-sized house. However, you may not need to caulk all the windows at once. If just one window has a pesky draft, you may only need half of a cartridge to fill in the gaps.
