"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

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Window washing usually refers to cleaning dirt and other debris off of the exterior of your windows, while window cleaning is a much more involved process that addresses the outside and inside of the glass, as well as the interior components. Window washing is more to improve the aesthetic of your windows, while window cleaning can improve performance, reduce the risk of damage over time, and even improve your home’s energy efficiency.

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

During hurricanes or other major storms, high winds can cause objects and debris to fly through the air, which can break your windows. Depending on how strong the storm is, the winds themselves may be strong enough to break your windows, too. Investing in storm windows or hurricane shutters can help protect you against potential window breakage.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.
