"This is our second window installation with Renewal By Anderson. We had an outstanding experience our first time around, and today our much anticipated installation of two very large stationary windows took place. Bebe and Ryan were our installers for this job. They were awesome!! They were friendly, they were prompt, and they even helped me figure out how to contact Anderson about a window screen that has been damaged by my landscapers. I very much appreciated their professionalism and their extra attention to detail. I highly recommend Renewal by Anderson for replacement windows. Thanks Bebe and Ryan, you guys are the best!!!"

"Window Wizards did an excellent job. They pressure washed my driveway, walkway, back patio, and also washed and cleaned my patio doors. Window Wizards was very professional and did a thorough job and I would definitely hire them again and refer them to others."

Windows FAQs, answered by experts

The material around a window is simply called the window frame, but the individual pieces also have different names. The top portion of the frame is called the head, the side pieces are called jambs, and the bottom portion is called the sill. If you have multiple windows next to each other, you’ll also have a mullion, which is the frame piece that separates the individual windows. Windows stacked on top of each other are separated by a horizontal frame piece, which is called a transom.

Insulating windows with plastic works, but it can be time-consuming, and the end results can—and often do—end up lacking in aesthetics. Window film and caulking your windows to make sure there are no drafts are two options that increase the energy efficiency of your home in a low-cost way. Plastic can be a good strategy while you consider alternatives.

Fiberglass and wood windows last the longest, with lifespans of up to 45 years or more with proper maintenance. Wood windows are more expensive than vinyl and aluminum windows, but they’re 10% to 20% less expensive than fiberglass windows. Repairing and restoring wood windows is also easier than with fiberglass windows, so they’re considered the more durable option overall.

Not every home needs window capping. Whether or not you need to cap your windows depends on your climate and window frame materials. Wooden windows should have window capping if moisture is a problem. Arid climates like the Southwest may not need window capping due to low rainfall and low humidity.

The best homemade cleaning solution for windows is one gallon of warm, distilled or bottled water mixed with five to ten drops of liquid dish soap. This is what professional window cleaners typically use when they make their cleaning solutions. Using bottled or distilled water will help avoid hard water stains after cleaning, and the soap will cut through grease, smudges, and debris on your glass.
